void uncaughtExceptionHandler(n exception * exception){
NSLog(@“崩潰:%@”，異常)；
NSLog(@ "堆棧跟蹤:%@ "，[異常調用Stack symbols])；
//內部錯誤報告

-(BOOL)application:(ui application *)application difinishlaunchingwithoptions:(ns dictionary *)launch options
{
NSSetUncaughtExceptionHandler(& amp；uncaughtExceptionHandler)；
//其他正常處理
經過測試，崩潰時可以輸出以下日誌:
