如何使用NSSetUncaughtExceptionHandler在Swift的UIView上显示异常消息 [英] How to use NSSetUncaughtExceptionHandler to show exception message on UIView in Swift

问题描述

我使用Martin R的答案在Swift中打印NSSetUncaughtExceptionHandler。

因为我有一个编译器错误消息说，AC函数指针只能从引用func或文字闭包形成。

解决方案

的NSSetUncaughtExceptionHandler

  NSSetUncaughtExceptionHandler {
 print（EXception Details Are \\\\
ExceptionName  - \（exception.name）\\\
Reason  - > \（exception.reason！）\\\
\（exception.description））
 print（exception.callStackSymbols）
 } 
  

I use Martin R's answer to print the NSSetUncaughtExceptionHandler in Swift.

How should I use NSSetUncaughtExceptionHandler in Swift

  func exceptionHandler(exception : NSException) {

    let alert = UIAlertController(title: "Exception", message: "\(exception)", preferredStyle: .Alert)

    self.presentViewController(alert, animated: true, completion: nil)

    print(exception)
    print(exception.callStackSymbols)
}

But how can I display the message in a UIView. Like this one

Because I got a compiler error message said that "A C function pointer can only be formed from a reference to a 'func' or a literal closure."

NSSetUncaughtExceptionHandler { exception in
            print("EXception Details Are \n\nExceptionName--> \(exception.name) \nReason -->\(exception.reason!)\n\(exception.description)")
            print(exception.callStackSymbols)
        }
