Capturing 'self' strongly in this block is likely to lead to a retain cycle
_player.completionBlock = ^{
[self stopPlay];
};
[self stopPlay];
};
上面在block里用self是会有提示：
Capturing 'self' strongly in this block is likely to lead to a retain cycle
可以这样改一下
__weak typeof(self) weakSelf = self;
_player.completionBlock = ^{
[weakSelf stopPlay];
};
_player.completionBlock = ^{
[weakSelf stopPlay];
};
