ios - 升级到 xcode 4.6 和 iOS 6.1 后出错 "used as the name of the previous parameter rather than as part of the selector"

更新到xcode4.6和ios6.1后,我收到这个新错误“'objectType'usedasthenameofthepreviousparameterratherthanpartoftheselector”。我多次得到这个。有什么想法吗?PS:它的显示方法是反向地理编码的自定义方法。-(void)getAddress:(NSString*)objectType:(CLLocationCoordinate2D)objectCoordinate 最佳答案 它说objectType是方法中NSString对象的名称,而不是方法名称的一部

iOS 7 MPMoviePlayerController 向前搜索按钮将视频带到结尾并显示黑屏

我在iOS7中面临MPMoviePlayerController的问题。我进入全屏,然后单击(只需轻按一下)向前搜索按钮(>>|),视频播放结束并显示黑屏并显示文本header上的“正在加载”。我为“MPMoviePlayerPlaybackStateDidChangeNotification”注册了通知。**[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(moviePlayerPlaybackStateDidChange:)name:MPMoviePlayerPlaybackStateDid

ios - 选择器作为 IOS 中的参数

我想为每个创建的按钮提出不同的方法。我尝试在viewDidLoad中调用“FirstImage”方法,但它不起作用。我对ViewDidLoad中的选择器有疑问。无法识别“FirstImage”,这是一个没有参数的无效方法。ViewController.m-(void)createFirstButton:(NSString*)myName:(SEL*)myAction{UIButton*btn=[UIButtonbuttonWithType:UIButtonTypeRoundedRect];[btnaddTarget:selfaction:@selector(myAction)forCo
