我有一个方法 -(void)showLyrics{} 我想从另一个方法调用它,但是在一定时间之后,每次连续调用之间的时间调用是不同的。我正在这样做
[self performSelector:@selector(showLyrics) withObject:nil afterDelay:2];
[self performSelector:@selector(showLyrics) withObject:nil afterDelay:5];
[self performSelector:@selector(showLyrics) withObject:nil afterDelay:10];
[self performSelector:@selector(showLyrics) withObject:nil afterDelay:12];
有没有人知道更好的方法?
