iOS7 Custom setMaximumTrack Image with UISlider doesn't show on the device

Question

I am using custom " UISlider " to show progress bar of MPMoviePlayer . Its working fine in simulator but when i run the same on device it does not apply the image which i provide instead it shows the default behaviour I am using the following code:

UISlider *slider;
[slider setMinimumTrackImage:[UIImage imageNamed:@"progress_bar_active.png"] forState:UIControlStateHighlighted];
[slider setMaximumTrackImage:[UIImage imageNamed:@"progress_bar_background_upper.png"] forState:UIControlStateNormal];
[slider setThumbImage:[UIImage imageNamed:@"thumb.png"] forState:UIControlStateNormal];

It is just really strange.My device is iPad 2(7.0.6) , iPad3(7.0.4) and Xcode Version is 5.1.1 .

Thanks in Advance.

尝试将状态UIControlStateNormal添加到setMinimumTrackImage和setMaximumTrackImage

[slider setMaximumTrackImage:[UIImage imageNamed:@"progress_bar_background_upper.png"] forState:UIControlStateNormal];
