Apologies, this was the common wisdom when I was doing iOS dev pre-iPad, pre-iPhone 3GS even. I haven't revisited localization since then. Should have thought more about that. My more recent iOS dev was mostly iterating on an English-only app.

tare: how much of it can you automate, i.e. with UIAutomation and captureScreenWithName?

It's all good; I finally got UIAutomation going so at least I can rip through the 180 screenshots in a somewhat automated way, but if you use the names (accessibility labels) its useless because those get translated too... So you have to access everything by index, which is fairly brittle.

I will say that German has had the best sales for me, like double the next which is Japan. Of course the US is #1 by such a ridiculous margin, then the commonwealth countries UK/Canada/Australia/NZ next (25% of US), then Germany (like 10% of commonewealth), then Japan, then France, then the Spanish countries.

Localizing to Chinese was a massive waste.

I haven't tried Korean, Russian, Italian, Dutch, etc so far.

DreadCthulhu: Sep 17, 2008; What the fuck is up, Denny's?!

A bit of a noobish question here: on the iPad version, I have a couple of visible controllers up at all times. One of them displays a bunch of stubbed content when the app initially loads, but then eventually it should refresh itself when it receives a notification through NSNotificationCenter and display the final data.

What I'm seeing though is that modifying the view doesn't seem to redraw it right away. In fact I have to wait 5-20 seconds for the new content to suddenly appear on the screen. Same thing if I pop open a full-screen modal and close it, viewDidLoad for that controller kicks in and displays the correct content.

I imagine I might have to force the view to be re-drawn on the screen, or is that always wrong and thus I should be using a more idiomatic approach to this problem?

[self setNeedsDisplay] when the content is updated might do the trick.

That was the first thing I tried, but it doesn't seem to do the trick. I could be doing this wrong though, no guarantee there.

I wonder if the fact that this specific controller is a "contained controller" under another controller screws something up in the redrawing. What's odd is that the same logic works perfectly fine on iPhone, when that controller occupies the whole screen. I receive the notification, the screen updates immediately. Not on iPad though.

Finally got my first app up on the app store! So proud of myself - pretty much learnt everything from scratch starting in August last year.

Stackoverflow and Ray Wenderlich are amazing resources when you get stuck. Any problem I had, someone else had figured it out already and posted about it there. Oh and of course lurking in this thread is great too.

Ok, retard me. I was completely oblivious to the fact that NSNotificationCenter receives messages on the same queue they're sent to (or the system is simply synchronous, thus quite similar) and so I was modifying the view in the background queue. What surprises me is that there was nothing in the logs about it. I thought it always lets you know when you're modifying the UI from outside the main thread..

Ah, the always entertaining "behavior is undefined". It might do nothing, it might crash, it might cause your computer to vomit rainbows. All are equally valid responses! On dotnet WinForms and WPF have the same problem; only one UI thread and you had better be doing all your UI modifications on that thread or you'll be sorry.

Of course the answer is mainQueue or BeginInvoke respectively, which begs the question: why can't these drat UI toolkits just do that for me?

A while back, when I was trying to figure out some random, drawing related crashes, I tried using swizzling to make it throw an exception when doing off-main thread UI work. I got it to work but it wasn't usable - UIKit was, as far as I could tell, intentionally splitting off some UITableView drawing onto a background thread. I'm still not sure that wasn't causing some of the issues I was seeing, either.

Weird. An update for an iPhone-only camera app I wrote was just rejected because the reviewer couldn't take pictures with it on an iPad. Except that I specifically tested it on an iPad, knowing that iPhone-only apps are still expected to work on iPads, and it works fine. Release builds, Ad-Hoc builds, etc., all work fine.

neu.Node is an implementation of Node.js-compatible API for iOS devices, which allows the application developer to embed variety of micro servers (http server, chat server, proxy server, game server, etc.) in their iOS applications.

With neu.Node, iOS devices are no longer just "client" devices. They become network "nodes", which actively participate in providing distributed computing services and enriching the user experience.

neu.Node enables new breeds of applications, such as:

� Server-less multi-player games
� Ad-Hoc/local social networking applications
� Peer-to-peer sharing, co-producing, and collaborations

Noob problem with UIWebView that is driving me nuts:

Context:
1. I am working on a storyboard app that I started from scratch. I like starting from scratch and wiring up the storyboard has not been a problem.
2. The initial view controller is a vanilla UINavigationController. The app is mostly a hierarchical navigation of various menus and content pages, but deeper and more varied than the Master/Detail template.
3. The root view controller of the nav controller is a vanilla UIViewController with a few controls, one of which is an "About" button.
4. Pressing the "About" button should segues to a view displaying a nicely formatted 'about' page that will be larger than the device display. Judging from the data views at my disposal, and Interface Builder's ease-of-use, it would appear that formatting content like this is better done in a HTML resource and displayed in a UIWebView than constructed using various UIKit objects (is this correct?).
5. In my attempt to use a UIWebView to display a nicely formatted 'about' page, it appears that the only way to get local content into a UIWebView is by sending a message such as loadHTMLString or loadData (is this correct?)
6. From the documentation that I can find it seems that such messages should be sent by the parent ViewController of the WebView in response to something like a viewWillAppear or viewDidLoad event, and thus will require a custom ViewController.
7. I created a custom AboutViewController that has an outlet for a WebView, wired up an instance of it as the target of the 'About' button segue from the root view controller, and wired up a UIWebView as its child and connect it to the outlet.
8. The custom view controller appears to never be getting messages such as viewDidLoad or viewWillAppear. It never hits breakpoints set in implementations for these.
9. Testing with a single-view application definitely shows that this technique of initializing WebViews works in other contexts, so I can only conclude that I am missing something about how navigation controllers work - which is frustrating because I've been scouring xcode's own docs such as "UI Navigation Controller Class Reference" and can find no warnings about such events being swallowed up.

Code for my custom view controller that is the target of the segue:

code:

@interface AboutViewController : UIViewController
@property (weak, nonatomic) IBOutlet UIWebView *webview;
@end

code:

@implementation AboutViewController
- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [_webview loadHTMLString:@"<html><body><h1>TEST</h1></body></html>" baseURL:nil];
}

-(void) viewDidLoad
{
    [super viewDidLoad]
    [_webview loadHTMLString:@"<html><body><h1>TEST</h1></body></html>" baseURL:nil];
}
@end

The WebView is a child of an AboutViewController and hooked up to its _webview outlet. All I get after the segue to the AboutViewController is a blank page. I have to be missing something pretty basic here.

Paolomania posted:

Noob problem with UIWebView that is driving me nuts:

90% of the time when this happens to me, it's because I forgot to change the class of the view controller in my storyboard from UIViewController to MyCustomViewController.

As for loading your HTML into you UIWebView, correct, you either load a string or a loadData to the view a la:

code:

NSString* path = [[NSBundle mainBundle] pathForResource:@"myFile" ofType:@"html"];
NSURL* url = [NSURL fileURLWithPath:path];
NSURLRequest* request = [NSURLRequest requestWithURL:url] ;
[_webView loadRequest:request];

code:

NSString *htmlPath = [[NSBundle mainBundle] pathForResource:@"myFile" ofType:@"html"]; 
NSString *htmlString = [NSString stringWithContentsOfFile:htmlPath encoding:NSUTF8StringEncoding error:nil];
[_webView loadHTMLString:htmlString baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]];

The second example is in the viewDidLoad of a navigation-based app I have in the store, so I know it works in that context.

I found cleaning target helps a lot too when wondering why changes in web views weren't showing up; maybe it clears the view's cache or something? :iiam:

Is the iOS 6.0 simulator busted in regards to app rotation? We have an iPad app that was built for 5.1 and is landscape only. It works fine in the 5.1 simulator and on all versions of iOS 5 and 6 on the actual devices but when I try to run it from Xcode in the 6.0 simulator all of the views are rotated 90° counter-clockwise.

I found this thread that sounds similar to my issue but the answer posted there doesn't seem to work at all. Has anyone else seen this? I know the simulators have their quirks and bugs but as of now I can't use the iOS 6 one with my app at all.

I'm not quite sure where I would even start to ask these questions, but as far as I can tell, this is the best place.

I've created spreadsheets for several things, utilizing vbasic for some of the functions. If all that stuff is already done, how difficult would it be to have an app developer turn it into a usable app for me?

What I'd like is my sales guys to be able to run the quote and other spreadsheets while they're at a meeting, and have a quote/engagement agreement ready for signature immediately. So, bonus points for having the ability to sign a document with a stylus on the ipad.

Would this be a super costly thing? Where would I even find good freelancers to do this for me?

Is this totally the wrong place to ask this question? Is it possible to have the app only available to my salesguys and not the general public through the app store?

I know, very dumb basic questions for this thread, but I'm not quite sure how to proceed.

I know, very dumb basic questions for this thread, but I'm not quite sure how to proceed.

It depends what you're looking to do. If you're just talking about converting the entire thing into an app, that's going to take longer than taking input from a given spreadsheet, crunching numbers, and creating a quote/agreement generated on that basis. If you're only going to be using the app in-house, you'll want to enter into the enterprise developer program, which allows you to bypass the App Store in a legitimate, legal fashion. The cost is $299/year, and that's going to be a fairly small amount compared to what you'll pay to have the app developed. Depending on the complexity of the spreadsheets, data manipulation, network integration, etc., etc. I'd say you're looking at a minimum of $5000, and it's hard to give an upper bound without knowing more about the spreadsheets involved and the exact functionality you need. This is obviously a very quick estimate, but in general there aren't many apps which are going to come in significantly under that number.

In terms of finding a freelance developer, I've picked up work from this forum before, and I'm guessing other developers around here have as well. Apart from that, I'd really have no idea where best to look, as I've picked up all my app development contracts from people I know in person.

Hey guys. Quick question and I can't figure out the correct way to search for this on google. Can I type an id pointer after initializing it? (I know I phrased that poorly, part of the reason I can't find an answer. For example:

code:

id thing = [game returnObject];
if([thing isKindOfClass:[Player class]]) {
// make thing a Player* pointer, permanently
} else if ([thing isKindOfClass:[Enemy class]]) {
// make thing an Enemy* pointer, permanently

Usually you don't even need to cast, it should only be necessary if there are conflicting method signatures (ie selectors with the same name but different params/return values). But anyway, if all calls made after the if-blocks are equally valid on Enemy- and Player-classes, I'd do one of two things:

Either use their common superclass which should be where their common methods/properties are defined anyway:

Objective-C code:

GameObject *thing = [game returnObject];
// do things

Or put the common method definitions in a category that they can both implement:

Objective-C code:

id<GameObject> thing = [game returnObject];
// do things

That way you don't have to do any logic.

To answer your question, no, you can't change the type of a variable after you've declared it. You would have to create separate variables with the types you want and have them all point to the same object.

I can't remember clearly, we just had a baby so I am running on zero sleep.

OK so I figured it out for my project at least. I guess the old shouldAutorotateToInterfaceOrientation works just fine as none of the new methods that I'm finding as solutions are ever being called and don't make a drat bit of difference. It turns out as per this thread in my AppDelegate's didFinishLaunchingWithOptions I had to change

code:

[self.window addSubview:navigationController.view];

code:

[self.window setRootViewController:navigationController];

I still don't get WHY this is the case and it seems there's some confusion in the community as well but at least my app doesn't blow up any more.
