Question

我使用UIProgressView进行音乐播放进度条，它在ios6或之前使用得很好，但ios7中存在问题。当我将ipad从Landscape旋转到Portrait时，它就丢失了。

以下代码

    [_playerBar setMiddleTrackImage:[IMG(@"player_progress_loading") resizableImageWithCapInsets:UIEdgeInsetsMake(4, 3, 5, 4)]];
    [_playerBar setMaximumTrackImage:[IMG(@"player_progress") resizableImageWithCapInsets:UIEdgeInsetsMake(4, 3, 5, 4)]];

- (void)setMiddleTrackImage:(UIImage *)middleTrackImage {
    [_progressView setProgressImage:middleTrackImage];
} 

- (void)setMaximumTrackImage:(UIImage *)maximumTrackImage {
    [_progressView setTrackImage:maximumTrackImage];
}

_progressView = [[UIProgressView alloc] initWithFrame:rect];
[_progressView setProgressViewStyle:UIProgressViewStyleBar];
_progressView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
_progressView.center = CGPointMake(_slider.center.x, _slider.center.y+1);
_progressView.userInteractionEnabled = NO;

[_slider addSubview:_progressView];

_progressView.progressTintColor = [UIColor darkGrayColor];
_progressView.trackTintColor = [UIColor lightGrayColor];

任何帮助表示赞赏！

我认为缺少UIprogressView是因为UIProgressView高度等于0.当你旋转到Portrait时，resizableImageWithCapInsets：UIEdgeInsetsMake（）和autoresizingMask改变高度

你可以使用

_progressView.autoresizingMask = UIViewAutoresizingFlexibleWidth

并调整高度

当ipad从Landscape更改为Portrait时，ios7 UIProgressView丢失
