Doctor w-rw-rw- posted:Subjunctive: Would FB consider open-sourcing React iOS? I can't really comment on possible future releases, though we really do like releasing useful stuff for iOS developers. Would depend on a few things, especially in the case of React iOS, which as described is a prototype. I'm doing work now to get a handle on the overall arc of what we're releasing and how to do a good job tending to all of it. I hope we'll be able to get a bunch more stuff out after ASDisplayNode, but don't have specific plans to share.

pokeyman posted:The interesting ones are the ones I haven't used long enough to dislike. The ones that generally seem to work are utterly uninteresting. But I'll throw one out there: ReactiveCocoa. A better language exists somewhere near where RAC is thrashing around. I'd agree with this; I don't know what that future language looks like but if you take some pieces of functional programming, RX (and LINQ - IObservable<T> is the inverse of IEnumerable<T>), C#, and Objective-C then there must be something there. Rust is also interesting for a lot of reasons, though I don't necessarily agree with some of the design choices (though the recent proposal to split mut to owned/mut is a good step IMHO). TICoreDataSync looked interesting but I haven't used it in anger. I used to champion RestKit but I've decided I don't care for it; too complicated and over-designed, with a steep learning curve. I yearn for a simple CoreData iCloud sync that works. I went through the trouble of creating a test project and filing a Radar during the iOS 7 beta and it seemed like the CoreData guys didn't understand what I was getting at and it's still broken and useless, 3 major iOS releases after it was made public. Thinking about it, I can come up with a lot more stuff I hate than anything else. I don't know if that says something about me or not.

Plorkyeran posted:I really wanted to like RestKit, but after actually using it in a nontrivial project I concluded it's a whole bunch of code that doesn't actually do anything particularly useful. Ripping it out and replacing it with Mantle, AFNetworking and just using CoreData directly made things quite a bit simpler. I've only used Mantle once but I had an annoying issue where if I declared a property an NSString and the server returned all numbers for that string the property would actually be set to an NSNumber by Mantle. Maybe I was just doing something silly?

To avoid getting the Invalid Product ID error with IAPs do you have to have a paid apps contract in effect with Apple? I've sent them my tax paperwork but it hasn't been processed yet, and that's literally the only thing I can think of that's the reason I'm still getting the error, I've gone through that checklist of 11 things to check when that's the error you're getting, and it's definitely nothing else.

Does anyone have any experience or advice with respect to CAScrollLayer's? Should I be using them if I am trying to design a timeline view (like a video editor / audio playback style timeline)? Is there something more useful than a CAScrollLayer? I am finding absolutely no info about it other than the Apple Developer documentation which usually means a "here be dragons" kind of deal. EDIT: with respect to using an NSScrollView since at the moment I don't think I have very specific needs for this view per se. ptier fucked around with this message at 02:17 on May 20, 2014 |

Is there anything that I'm missing that's different between CGPoint and CGVector aside from their names? They both take CGFloats but the CGVector's coordinates are signified by dx and dy, instead of just x and y. The reason I'm asking is because I'm curious. I've been using CGPoint for velocities and it hasn't occurred to me until now to use CGVector. LP0 ON FIRE fucked around with this message at 15:23 on May 20, 2014 |

I'm going to say its all semantics in how you want to represent your data in code, if you want var.dx over var.x. Interestingly CIVector has a constructor for point but not CGVector. I've seen several libraries where vector types made for more clear parameter types but points are used. Edit: unless you find yourself frequently having to convert from one to the other when interfacing with other api.

Normy posted:I'm very new to iOS development. I'm trying to create and application with a Tab Controller and I want to also have a custom timer view that is present on every tab. Is this something I can do in IB or do I have to do it programmatically? Depends on what you mean by "custom timer view". You can create a container view controller that has two children - the timer and the tab controller. It would be responsible for the layout and so on. Be aware that the tab controller doesn't necessarily like not being the root view controller and can get a bit testy. If you just want to drop your timer view on each of the tab's content views then that works, though it is duplicated obviously. I'd probably go for having my own base view controller inheriting from UIViewController, then use that as the class for the tab content view controllers in IB/Storyboards. That base class' job would be to inject the timer view with layout adjustments as needed. That keeps the tab controller happy as the root. However due to the way Xcode/IB work there is no "design time" mode so you won't see any of that in the Interface Builder design views. You'll just have to trust that it works at runtime. So the short version is just do it in code. Interface Builder has nothing in common with other GUI designers (like VS WinForms for example). You cannot and should not expect to get your UI look setup in IB; you are just creating a rough outline and will polish it up in code.

I'm having horrible problems with a UICollectionView I am using as a keypad with many buttons. When a touch begins, a cell is highlighted, fair enough - but I’d like a cell to *unhighlight* when a touch is released. Currently I get around this by calling reloadData every time basically anything happens, but, as I have canCancelContentTouches turned on, when you scroll on top of a cell, the cell gets stuck in the highlighted position.  Is this doable in a sane or reasonable way or am I fundamentally misunderstanding the way a UICollectionView is supposed to be used?

Doesnt UICollectionView have methods that your delegate can implement to be notified when a cell is going to be highlighted (so that you can decide if the cell even should be highlighted)? Can't you just use that to be notified when a cell has been highlighted and then unhighlight it a split second later? edit: also, my view is that if you want a button, or button-like behavior, then use a button. Otherwise you wind up reimplementing stuff that UIButton gives you for free. Just make a grid of buttons, and tag each one appropriately. Have them all use the same method when tapped, and determine which got tapped by its tag. You can use autolayout or a small amount of simple manual layout if you're worried about it working on different screen sizes. Doc Block fucked around with this message at 20:32 on May 24, 2014 |

I'm working my way through a course for development and one thing I've been trying to wrap my head around is delegates. I understand their function, but what I need help clarifying is their assignment. Given that I have a view controller A and view controller B A references the B delegate where B defines the protocol. So when A is set as B's delegate through a segue, are we saying that in B, we'll be using A's implementation of the protocol methods? and in this sense, is B used just to pass information to A so it can perform something for itself?(A). What I'm mainly confused about is: "is the implementation working for A or B". If anyone can shed some light for me that'd be great.

Manic Mongoose posted:What I'm mainly confused about is: "is the implementation working for A or B". B. It's delegating various decisions and/or calculations to A. Think of it as B sending a message to A saying "help me out, what happens when this row of my table is selected?" There's a maxim, "you call a library, but a framework calls you". If you can puzzle on that and know which side delegation is on, you'll be set.

I got it working right in the end, I wound up overriding -touchesBegan: et al like lord funk told me to (you don't need a tap gesture recogniser as UICollectionViewCell already inherits from UIResponder). But instead of using these to set the highlight on the cell I added an additional property, tapped, which I use to set the alpha value on the cell, while highlighted now does nothing. Hooray

I have a UITextView inside a UICollectionView that's reusable. Sometimes, and I don't know why, when I update an existing view with new text, the text doesn't show up at all. I'm trying to dig into it more, but it happens randomly and if I scroll back and forth over the cell, the text will eventually show up/hide itself again.

On the face of it it sounds like a reusable view issue. i.e. - you're dequeuing a reusable view and not setting that view's textview text when you do it. Or you're trying to hold onto a reference to a cell to make changes, which is a bad idea. Just throwing these out there.

I had an old assignment of autoresizingmasks that I'd forgotten about in my view's init, which was automatically changing its height to 0 (god knows why) after I was setting its height. Now it works! But still, screw UITextViews!
