显示警报，您可以使用以下方法： 将以下方法添加到您的应用程序委托中，并确保在启动时只调用一次：#import "/usr/include/objc/objc-runtime.h" - (void)_handleError:(NSNotification *)notification { // do nothing, or add any custom error handling code here } - (void)patchMPVVC { // add the _handleError: method to the MPVideoViewController class Class class = NSClassFromString(@"MPVideoViewController"); Method myMethod = class_getInstanceMethod([self class], @selector(_handleError:)); class_addMethod(class, @selector(_handleError:), method_getImplementation(myMethod), "v@:@"); // swap method implementations: SEL selector = sel_registerName("_videoView_playbackErrorNotification"); Method originalMethod = class_getInstanceMethod(class, selector); myMethod = class_getInstanceMethod(class, @selector(_handleError:)); method_exchangeImplementations(originalMethod, myMethod); }类和方法。
