iOS app crashes when first opened by URL Scheme

问题

My app handles URL Schemes. When it is already running and gets called from another app, it behaves correctly and without a problem. However, when it is completely closed (as in not-in-background-mode), and another app calls it, it crashes immediately.

I've already set the "Wait for executable to be launched" option so I could debug the application:willFinishLaunchingWithOptions: but it seems that it is not getting called. I've also implemented -application:openURL:sourceApplication:annotation: but it seems that its not getting called either.

Here's the crash:

libsystem_kernel.dylib`__pthread_kill:
0x10a79e278:  movl   $0x2000148, %eax
0x10a79e27d:  movq   %rcx, %r10
0x10a79e280:  syscall 
0x10a79e282:  jae    0x10a79e28c               ; __pthread_kill + 20
0x10a79e284:  movq   %rax, %rdi
0x10a79e287:  jmp    0x10a799ca3               ; cerror_nocancel
0x10a79e28c:  retq   
0x10a79e28d:  nop    
0x10a79e28e:  nop    
0x10a79e28f:  nop    

Any idea on how to solve this, or what am I doing wrong? I'm using iOS 8 GM and Xcode 6 GM.

回答1:

Well, I fixed it! I just had to check for the following case in my AppDelegate didFinishLaunchingWithOptions method.

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

            if ((launchOptions) != nil) {

                if ((launchOptions?[UIApplicationLaunchOptionsURLKey]) != nil){


                }

Thanks for the support!
