AVP 播放器状态？

因此，我无法阅读如何使用 AVPlayerStatus 属性，

我已将 @property(nonatomic, readonly) AVPlayerStatus *status; 正如文档告诉我的那样，但是似乎无法找出我如何使用

AVPlayerStatusUnknows..

我想在类似的事情中使用它，

while(AVPlayerStatusUnknows)
{ 
      //DO SOMETHING 
}

有人可以在这里帮助我吗？

谢谢

@Patrick您不能使用 AVPlayerStatus 对象，因为它不是类或结构（或联合）。它是一个枚举器。我们用它来检查 switch 中的条件（如果我们正在创建它）。上述@Amorya建议的方法是如何使用AVPlayerStatus。

希望这对您有意义。

检查文档。

编辑：

您正在寻找的是这样的东西。我认为这不会起作用，或者可能会起作用。但你会得到基本的想法。

[yourActivityIndicator startAnimation];
while(yourAVPlayer.status == AVPlayerStatusUnknown) {}
[yourActivityIndicator stopAnimation];

或者，如果您只是使用 GCD 调用自定义队列中的最后 2 行，它会显示您正在寻找的内容。

像这样的东西，（不确定这是否是确切的语法）

[yourActivityIndicator startAnimation];

dispatch_queue(^{
       while(yourAVPlayer.status == AVPlayerStatusUnknown) {}
       [yourActivityIndicator stopAnimation];
 });

@Patrick you cannot use the AVPlayerStatus objects because its not a class or a structure (or Union). Its an enumerator. we use it for checking a condition where in switch mostly (if we are creating it). The above method suggested by @Amorya is how to use AVPlayerStatus.

Hope this is making sense to you.

Check the documentation.

Edit:

what you are looking for is something like this. I don't think that this will work or it might. but you will get the basic idea.

[yourActivityIndicator startAnimation];
while(yourAVPlayer.status == AVPlayerStatusUnknown) {}
[yourActivityIndicator stopAnimation];

or if you just call the last 2 lines in a custom queue using GCD it will show you what you are looking for.

something like this, (not sure if this the exact syntax )

[yourActivityIndicator startAnimation];

dispatch_queue(^{
       while(yourAVPlayer.status == AVPlayerStatusUnknown) {}
       [yourActivityIndicator stopAnimation];
 });
