如何处理未捕获异常

If use NSSetUncaughtExceptionHandler, it only handles objective-C runtime errors. https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/index.html#//apple_ref/c/func/NSSetUncaughtExceptionHandler

如果使用NSSetUncaughtExceptionHandler，它只处理objective-C运行时错误。https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/index.html / / apple_ref / c /函数/ NSSetUncaughtExceptionHandler

NSSetUncaughtExceptionHandler can catch the exception:

NSSetUncaughtExceptionHandler可以捕获异常:

var a: NSArray = [""]
println(a[2])

But NSSetUncaughtExceptionHandler can not catch exceptions:

但是NSSetUncaughtExceptionHandler不能捕获异常:

var a = [""]
println(a[2])
