推荐答案

当你初始化电影播放器​​时，你已经有了一个.MPMoviePlayerController 只能有一个.您可能正在循环执行此操作.您需要将最后一个设置为 nil 或不断重复使用同一个.

When you are initing the movie player, you already have one. There can be only one MPMoviePlayerController. You are probably doing this in a loop. You need to set your last one to nil or keep reusing the same one over and over.
