问题 I have spent over a ton of hours working on an app, it works perfectly on iOS 7, both on device and simulator. When I run it on iOS 8, it works perfectly on simulator. But for some reason, when I run it on my iOS 8 device, it starts crashing weirdly. If I implement CLLocation, the app will run smoothly for the first 5 times that I run it. Then it will crash the MOMENT I compile it for the next 5 times. After that 5 times, it starts compiling smoothly again. Then after 5 more times, it crashes

问题 I have written a small private framework that I want to share between a few iOS apps. Here is the work flow I envision: Pull SimpleApp from source control. Pull BobFramework from source control. Somehow embed BobFramework into SimpleApp using Xcode. Build project. Done! The problem is how do I accomplish the "embed using Xcode" step? I cannot find step-by-step instructions on how to do this. Apple's docs are an out-of-date lie. All the Stack Overflow questions I have found assume readers know

问题 I am trying to make four separate variables that are all different so that a and b are different, a and c are different, b and c are different and so on so forth. Here are the four variables. var a = Int(arc4random_uniform(5)) var b = Int(arc4random_uniform(5)) var c = Int(arc4random_uniform(5)) var d = Int(arc4random_uniform(5)) 回答1: let a = Int(arc4random_uniform(5)) var b = Int(arc4random_uniform(5)) while b == a { b = Int(arc4random_uniform(5)) } var c = Int(arc4random_uniform(5)) while c

问题 I am trying to add an extension to Swift so I can format Doubles as found in this answer here Precision String Format Specifier In Swift Not ideal, but best solution I can find so far. However I cannot seem to add extensions to my project. Extensions work fine on playground, but when I try to add it to my project, I get the SourceKit service crash error every time I try to add the code in. I also get an error stating "declaration is only valid at file scope". I have not previously used

问题 Xcode 6 does not have a menu item to access provisioning profiles. How can one manage existing provisioning profiles (list, delete, etc)? For reference purposes, a similar question was asked pertaining to Xcode 5: Provisioning Profiles menu item missing from Xcode 5 I commented on the selected answer that in Xcode 6 the Accounts tab now shows Repositories. I was encouraged to start a new question to help others find information relevant to Xcode 6. 回答1: Adding Apple ID As Bo A points out, in

问题 I'm trying to implement an unwind segue that will take me from the last view controller back to the todo-list controller. Here's my storyboard Without the tab bar controller, the unwind segue works fine. However, as soon as I add the tab bar controller, the unwind stopped triggering. What am I doing wrong? Thanks Edit: Also, actions created on the bar button in the last view controller do not trigger when the tab bar controller is implemented 回答1: I have had a similar situation and I was able
