If they feel that you're not adding anything to the user experience over a website, then they might reject it on that basis. Nothing seems particularly bad about that storyboard, but at the same time it seems like you aren't really getting any utility out of making a native iOS app over making a website.

Especially in that case. I don't see any way to edit data, so you essentially have a book with a fancy hierarchy. Is there a specific reason you're not publishing this as an eBook? At least add some cool features like a way to scale recipe amounts up and down, or something that makes it more than just a collection of information. Even then, without the ability for the user to actually extend the information by (for example) entering their own recipes, they might feel it's not worthy of being on the App Store. Have you seen any apps with similar functionality and layout available on the App Store?

Last weekend I finished the Big Nerd Ranch iOS book, and am about to undertake my first app. One thing that a few Internet articles recommended was to create your interfaces by hand programmatically, to really learn what's going on under the hood. I've also read that you should just use Interface Builder because it owns, and dive deeper once you've got some experience under your belt. Does anyone in here have any particular opinions on this topic?

This is an ongoing debate and has been for decades. Pick one and keep working on your project. Try the other one if you do get bogged down. It's easy to mix and match code-only and IB so you can't go wrong.

When I started it actually bothered me that you had to still use code if you choose to use IB, since not all the view properties are represented there. So I shunned IB and did everything in code.

That was before storyboards. Now IB is just so much more useful I think it would be silly to ignore it for new projects. Sure, you will still touch up your views with code, but the view controller switching alone is worth using IB.

loving autolayout.

It takes me forever to get things tweaked in IB using autolayout since moving one thing seems to change everything else I set there. Or if I pin the height on a button, moving it or changing the text seems to remove the pin andasodas

I just got used to how Auto Layout behaves in IB, so it doesn't bother me like it used to. It's just too convenient to pass up when I can make complex split view resizing behaviors using no code.

It is an iPhone version of a friend's Android app. I pretty much did a direct conversion of his android UI to native iOS controls. I guess I need to let him know that Apple wants more interesting functionality if he wants his app up there.

I'm trying to display an image in a UITableViewCell and I'm running into a bit of an issue. I have an array called Articles of dictionary objects, get the image URL from each dictionary, and then create a UIImage from that and then display it in the cell. However, the image isn't displaying for me.

Here is my code, this is all in tableView:cellForRowAtIndexPath:

code:

NSDictionary *article = [articles objectAtIndex:indexPath.row];
NSString *imageURL = [article objectForKey:@"image_url"];
NSURL *url = [NSURL URLWithString:[imageURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSData *imageData = [[NSData alloc] initWithContentsOfURL:url];

CGRect imageFrame = CGRectMake(2, 20, 75, 125);
        
UIImageView *articleImage = [[UIImageView alloc] initWithFrame:imageFrame];
articleImage.image = [[UIImage alloc] initWithData:imageData];

[[cell contentView] addSubview:articleImage];

For some reason this isn't working. I've made another single view project and the images are loading fine, and if I have a picture saved into the project and load that image into articleImage there is no issue. Any ideas?

I don't have an answer for why this isn't working specifically, but in general this approach is a bit unsafe. I imagine this code is in cellForRowAtIndexPath, right?

I believe [[NSData alloc] initWithContentsOfURL:url] is going to block until all the data is downloaded, you really don't want that in your tableview rendering code, especially on the UI thread. (I'm assuming the images are remote here). Consider using ~~SDImageView~~ SDWebImage or something for remote/async images.

But also, you can start debugging by replacing [[NSData alloc] initWithContentsOfURL:url] with "initWithContentsOfFile" and using a local file just to see what happens.

You're right, looks like that's the case. Changing [[NSData alloc] initWithContentsOfURL:url] to initWithContentsOfFile loaded the image, so I'll have to load all the images first before rendering the table. Thanks for the point in the right direction.

# ? Feb 10, 2013 03:36

Doc Block: Apr 15, 2003; Fun Shoe

Why do you have to load all the images first? If they're being downloaded over the network, just download them asynchronously in a background thread as-needed and then stuff them in the appropriate imageView when done. If you don't want to write the code yourself, use something like AFNetworking's UIImageView+AFNetworking category to do it for you.

Well, you can replace the image with an ActivityIndicator while it is loading. You'll want to cache your images and load them on demand. Look into SDWebImage: https://github.com/rs/SDWebImage

e: yeah, or what Doc Block said. In any case, this is a near-solved problem and there are probably numerous examples of a scrollable UITableView with remotely loaded images.

I cannot find anything via google, so once again, I turn to you kind folks. In an iOS app, I write data to a file in the Documents directory. It does so, and I can read the data back out later in the app. Hooray!

I then install a newer version of the application (downloading via Enterprise deployment) "on top of" yesterday's build. I get to the screen where I read the data file previously written and:

C code:

NSUnderlyingError = 
"Error Domain=NSPOSIXErrorDomain Code=2 \"The operation couldn't be completed. No such file or directory\"";

I have the device plugged in and am looking at the Documents directory in the Organizer, and I'm staring at the file. The app is reading other files from that directory as well. Has anyone run into anything similar?

Leave the Shell text field as /bin/sh. Just have

as the first line of the run script. Leave out the export part of the path statement.

It's a shell script, so don't break a single command up across multiple lines. Each line is being executed as a separate command.

edit: you can use "\" to indicate that the next line should be part of the current one, so maybe try

code:

PATH=/usr/sed-4.2/bin:$PATH

sed -n '/<tileset\s\+firstgid="1"/ { \
s/\(<tileset\s\+firstgid="1"\).*/\1/p \
r /Resources/maps_sideScrolling/tileProperties.txt \
:loop \
n \
s/.*<layer name="background".*/&/p \
t \
b loop }' ~/Resources/maps_sideScrolling/ruinsItemCave2.tmx

if you absolutely have to break it up.

As always, try it and see what happens.

For what it's worth, collection views can do pretty much anything you like. They're the graph theory of UIKit: every problem can be solved with a collection view.

And if you need collection views on iOS 5, there's a polyfill called PSTCollectionView.

It seems like a mega-nib, so it has merge issues, just opening it will change it, it's dog-slow, and it crashes Xcode much of the time. Made worse by the fact that it's a single gargantuan file rather than a number of smaller files.

It does some fun resource management, for one thing. Unlike Xibs, where the whole tree gets built at init time, storyboards will load individual parts lazily. You can basically assemble large sections of views and their transitions in one file, with the downside being they're all in one file and XCode will try and show you all of them.

I'm also pretty sure the "changes when you open it" thing is just a symptom of an XCode upgrade. As of sometime recently they started automagically upgrading your interface files to the schema of the last version, which means your whole team doesn't have to upgrade at once but you also don't end up with XIBs from 2009 in your source tree as easily.

File bugs for the crashes, that ain't right.

I think of storyboards as the next level of abstraction above nibs. A nib combines many views under one view controller; a storyboard combines many nibs under one app. They're useful for the same reason nibs are useful: they configure and instantiate many objects with a single line of code.

Unfortunately I found iPad storyboards unusable. You must zoom to 100% to edit anything, yet every view controller insists on drawing at least one view (sometimes many in the case of tab bar or navigation view controllers) at 1024x768. I couldn't meaningfully edit an iPad storyboard on a 27" display, let alone anything smaller. So I gave up.
