我在我的AppDelegate.m中使用以下代码片段来捕获异常：

void uncaughtExceptionHandler(NSException *exception)
{
    NSLog(@"CRASH: %@", exception);
    NSLog(@"Stack Trace: %@", [exception callStackSymbols]);
}

如何避免此警告：

Semantic Issue: No previous prototype for function 'uncaughtExceptionHandler'？

最佳答案

只需在.h文件中声明此方法

void uncaughtExceptionHandler(NSException * exception);

或将此函数放在调用函数上。

    void uncaughtExceptionHandler(NSException *exception){
       //your code
    }

-

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

            NSSetUncaughtExceptionHandler(&HandleExceptions);
//your code

return YES;

}
