objective c - obj_msgSend function pointer crash when build with 64bit arm64 -


Actually my basic code works well with Xcode 5.0.2 and is also great for sending app stores: 

  objc_msgSend (self.target, self.successAction, category);

This line crashes with Xcode5.1 Beta 5. I got the solution to fix the accident: 

  // Solution ID (* response) (id, sel, id) = (id (*) (id, sel, id)) objc_msgSend; Feedback (self.target, self.successAction, category);

And when using the recommended solution I would like to use Xcode 5 or Xcode5.1beta to test on the device (iPhone 5s) or simulator (32 bit or 64 bit) The problem is not found. Architectures set in Build Settings "Standard Architecture in XX5 (ARM 7, ARM 7)" and "Standard Architecture (ARM 7, ARM 7, AR64)".

However, my new version of the app is ready for sale on the App Store today and it crashes on every device (iPhone 5S, 5, 4S) (according to Crashcat report). Since I do not get an accident using Xcode (build on real device), I do not know whether I fix the problem or not before reviewing the apple.

Finally, I can reproduce the accident right now. Simply edit the scheme and replace "Run YOURAPPNAME.play" from "debug to release".

And immediately after reproducing this bug, I know how to fix it, since my selector works type is zero (does not return anything), only copy the question to me Should not (using "ID").

By changing: 

  ID (* response) (id, sel, id) = (id (*) (id, sel, id)) objc_msgSend; Feedback (self.target, self.successAction, category); From

: 

  zero (* response) (id, sel, id) = (zero (*) (id, sel, id)) objc_msgSend ; Feedback (self.target, self.successAction, category);

This fixes !! Or thanks to a one-line code: 

  ((zero (*) (id, sel, id)) objc_msgSend (self.target, self.successAction, category);

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
