我很难尝试UISlider在我的应用上替换播放不可见MPMoviePlayerController的UIProgressView.
UISlider只是创建，更改非常直观，几乎在更新选择器上从MPMoviePlayerController我更新其当前状态：
之前我从以下内容定义了最小值和最大值MPMoviePlayerController：
-(void)UpdateTime:(NSTimer*)Timer
{
[self.sldProgress1 setValue:[[NSNumber numberWithDouble:playerSong.currentPlaybackTime] floatValue]];
}
UIProgressView没有提供类似的方法，我也没有在网上找到与我正在尝试做的事情相匹配的样本：
sldProgress2.maximumValue = [playerSong playableDuration];
sldProgress1.value = 0.0;
有什么建议么？
UIProgressView doesn't have the concept of a user-settable max value - it's just 100.0. To make it work as you want, you'll have to do some math. Luckily, it's easy math:
CGFloat percentComplete = [playerSong.currentPlaybackTime floatValue] / [playerSong.playableDuration floatValue];
That will give you the percentage of the song that's complete, and you just update your UIProgressView to that number.
progressView.progress = percentComplete;
More or less - this code was mostly pseudo based on your question, but that's the idea.
您可以继续使用 UISlider 并使用以下行隐藏 thumbImage：
[mySlider setThumbImage:[[UIImage alloc] init] forState:UIControlStateNormal];
这对我有用。
