Is there a reason for using the user's Documents folder? Do you want the user to have access to the files through iTunes File Sharing? or can they add their own? If not I think just keeping the files in the application bundle should be fine. Anyone noticed UISliders acting poorly in iOS 8? If you tap on a slider that is at 100%: ---------0 it moves the handle to the left: -------0-- and keeps doing so until the handle is in the middle.

I guess I was thinking there was some sort of App Data folder which only the app itself had access to.

I had one stupid, nagging issue with auto layout still. I have a UILabel that I want rotated 90 degrees. I had all kinds of issues where auto layout would make the label do very odd things (go off screen, rotate back around, disappear entirely) when animating constraint changes to the parent view. I was chasing my tail by trying to compensate for all of these during the layout subview process. I finally got it mostly working, but it involved checking the major iOS version and changing the timing in seemingly arbitrary ways depending on the result. That is horrible and couldn't stick. In a moment of desperation, I removed the UILabel from my .xib and replaced it with a UIView placeholder in the correct, rotated dimensions. Manually putting the UILabel in there still doesn't work right all the time. Instead, now every time the label text is changed, I create a temporary UILabel, render it into a rotated CG context, yoink the CG context into a image, make a UIImageView, and smack that UIImageView into the center of my placeholder view. That was... fun. At least all of my weird layout problems regarding that label behaving differently across iOS versions now seem resolved. Remember, kids, auto layout does not play nicely with transforms.

HaB posted:stuff Notifications can only use sounds in your app bundle so I hope you are prepared to ship all IAPs from the beginning, which it appears you are. There is no point in copying the files around, that's just a waste of space. Give them unique names and include them in your project. You can play them from there as well as use them for notifications. When you ask for bundle path to resource you're just getting a path into the filesystem... bundles are just directories.

I got an email out of the blue from them about a position and although I'm not actively looking for work, I'm a bit curious to say the least. Is it me you're looking for? I'm ex-Facebook, sorta. Facebook has the best iOS developers outside of Apple, and the company is structured such that you can cast a wide net when you need the expertise (i.e. stuff that Stack Overflow wouldn't cover, ranging from intermediate to pretty darn advanced). It also enables you to be a Silicon Valley man-child, if you want, whose every need is taken care of*. This frees up you and your high salary to compete with your coworkers to see who can buy the best drone with the highest-quality camera and gimbal apparatus, which you will invariably fly around campus and post on your timeline (or on Instagram. Bonus points: Hyperlapse) for your Facebook friends to see, and your non-Facebook friends to be jealous of – you hope, because that drone didn't come cheap. * I jest, but it's really quite great. EDIT: You might also want to talk to Subjunctive, who's a true-blue Facebooker, or ultramiraculous, who recently joined EDIT 2: Also unrelated, but I missed this a couple of pages ago: Nipplebox posted:The documented convention is that, when passed nil, -isEqual: returns NO and -isEqualTo*: throws an exception, but this isn't consistent across all of Cocoa.

So post initial iOS8 release it's time to clean up some cruft. Is there an easy way to share config settings, or plist settings between two targets in the same project? Basically our use case right now is that an extension needs to know certain bundle information about the containing app and vice versa, we also have different values for these based on the configured environment (debug/adhoc/stage..). The solution so far has been custom config fields in each target but ideally we would just load some common file in both targets, having to make sure a string is the correct value in multiple places is error prone. I'm guessing a project wide UserSetting is the answer?

Kallikrates posted:So post initial iOS8 release it's time to clean up some cruft. I think you want .xcconfig files. You can extract common build settings into a single xcconfig then base each target's configuration from that xcconfig. I forget the details for configuring Xcode but that should give you something to look up. xcconfig files can include one another and interpolate other build settings, you can get a lot done with them.

Although I bet it isn't that painful, I can't bother spending any energy dealing with bridging the two languages between files. Like I could make one new view area with Swift, but if it needed to communicate / pull information from existing Obj-C areas there would be those moments where I'd have to stop and think. And god knows stopping and thinking has never been on my agenda.

Our iPhone app has swift in production right now if anyone has questions. I wrote our extension all in it and some of the signaling code back and forth to the main app. Getting unit tests to work with a mishmash of swift and objc was complicated and I had to fall back to a really hacky way to do it. Seems apple wants your swift to be compiled into a module you can use from obj-c, but I just use it raw from my obj-c and vice versa and this caused issues with generated bridging headers.

So who wants to tell me how Hangouts and Messenger are managing their keyboards? They're using interactive dismiss so you can drag down to hide the keyboard, but the text entry view moves with it. We were able to mostly replicate this by adding an empty inputAccessoryView to our textfield, and observing its superview's frame changes so we could match the movement of the textfield with the keyboard. This doesn't work on iOS8. The observation of the superview does absolutely nothing, so when the keyboard comes up, our text entry view stays put, and when we drag to dismiss, it doesn't move either. I'm able to find the keyboard view through other means, but KVO still isn't giving me anything. Also, how the gently caress are they doing interactive setting of first responder? When the keyboard is hidden, I can pan up from the textfield and the keyboard slides up as I do. I have no idea how they did this without some sort of private fuckery. It's hurting my brain.

Yeah we were doing something similar before to have it move in time with the automatic animation via the notifications, but now that we're doing interactive dismiss, it's not working out. iOS8 broke it all and made me sad

Has anyone heard or seen anything about Xcode 6 failing with incremental builds? Maybe of large C++ projects. Someone at work is convinced that it's unusable if you edit a header 'bad things happen.' And other teams have been on it since day of GM seed without seeing anything odd.

Unrelated to your question but double check you aren't creating a retain cycle in that completion handler. Also prefer tableView:cellForRowAtIndexPath: over dequeueReusableCellWithIdentifier: the former will remove the need to nil check since it will always return a cell

If that's true then how do you specify which built-in style of cell to use? Or are people really building their own cell types for every single table view?

It makes it easier to bind cells logically (in terms of their functionality) to the view controller (presumably where the meat of the behavioral code lives), instead of bloating said view controller with a lot of gesture recognizers or accesses to random owned views to modify state.

Why would I waste time recreating one of the standard table view cell styles for that? You don't have to if you don't want to! But it's neither hard not time consuming to subclass a UITableViewCell (hell, even put it within the same file as the VC  ) and put whatever subviews you want in there.
