ios - 崩溃-[AVPlayerItem _attachToPlayer :] An AVPlayerItem cannot be associated with more than one instance of AVPlayer

我有一个崩溃影响了我大约10%的用户,但我无法重现它,并且不知道发生这种情况的确切时间。Crashlytics报告说,大约一半的崩溃用户没有关注应用程序,即做背景音频或AirPlay。该应用程序播放HLS视频流,并在后台切换到纯音频版本。有什么问题吗,或者为什么我的单例Player类中会有多个AVPlayer实例?谢谢!ExceptionType:NSInvalidArgumentExceptionReason:AnAVPlayerItemcannotbeassociatedwithmorethanoneinstanceofAVPlayerFatalExceptionLatestCra

ios - NS无效参数异常 : "Unrecognized selector sent to instance"

我遇到了一个我并不真正理解原因的问题。异常没有给我理解问题的线索。我想根据myArray中给定的数据修改我界面中UILabel的内容。但是,正如我在函数“cellForRowAtIndexPath”中指定的行,程序会触发异常。这个问题是什么原因造成的?@property(strong,nonatomic)NSMutableArray*myArray;//-(void)viewDidLoad{[superviewDidLoad];//Doanyadditionalsetupafterloadingtheview.[myArrayaddObject:@{@"field1":@"myfiel
