Question

-(void)testPause_trial
{
    MyMediaPlayer *player = [[MyMediaPlayer alloc]init];

    id mock = [OCMockObject partialMockForObject:player];

    AVQueuePlayer* result = [[AVQueuePlayer alloc]init];
    result.actionAtItemEnd = AVPlayerActionAtItemEndPause;

    [result addObserver:player forKeyPath:@"status" options:0 context:nil];

    [result addObserver:player forKeyPath:@"rate" options:0 context:nil];

    [(PTMediaPlayer*)[[mock stub] andReturn:result] createAVQueuePlayer:OCMOCK_ANY];

    //Start playing
    [player play];

    [player pause];

    [mock stopMocking];

}

没有这一行“ [[（PTMediaPlayer *）[[mock stub] andReturn：result] createAVQueuePlayer：OCMOCK_ANY];”，我的代码可以正常工作。

但是要包括这一行：

未为keypath = @“ status”调用observeValueForKeyPath
对于keypath = @“ rate”，出现以下错误：

observeValueForKeyPath：ofObject：change：context：消息已收到但未处理。

关键路径：费率
