我目前正在尝试在MPMoviePlayerViewController中自定义一些内容,但我在使用其中一个滑块时出现问题。
如下所示,它具有2个滑块,一个音量滑块和一个小持续时间滑块。
使用以下内容:UIImage *thumbImage = [UIImage imageNamed:@"MPThumbSelected.png"];
[[UISlider appearance] setThumbImage:thumbImage forState:UIControlStateNormal];
我可以自定义每个滑块,包括音量滑块,但由于某种原因,导航栏中较小的滑块不会更新。有没有人有什么建议?任何帮助将不胜感激!谢谢!!

您可以更改MPMoviePlayerController
的默认控件。您可以做的一件事是您可以隐藏MPMoviePlayerViewController
的默认控件并添加自己的自定义音量滑块。
moviePlayer.controlStyle=MPMovieControlStyleNone;
您可以像这样添加音量按钮:
UIButton *soundBtn=[ UIButton buttonWithType:UIButtonTypeCustom];
soundBtn.frame=CGRectMake(400,10,35,35);
soundBtn.showsTouchWhenHighlighted=YES;
[soundBtn setBackgroundImage:[UIImage imageNamed:@"valume.png"] forState:UIControlStateNormal];
[soundBtn addTarget:self action:@selector(valumeAction) forControlEvents:UIControlEventTouchUpInside];
[controllsView addSubview:soundBtn];
对于Volume,您可以使用MPVolumeView类
-(void)volumeController{
volumeView = [[UIView alloc]initWithFrame:CGRectMake(40,410,100,20)];
volumeView.backgroundColor = [UIColor clearColor];
[self.view addSubview:volumeView];
//MP Valume Slider for controlling thew volume
volumeslider = [[[MPVolumeView alloc] initWithFrame:volumeView.bounds] autorelease];
NSArray *tempArray = volumeslider.subviews;
for (id current in tempArray){
if ([current isKindOfClass:[UISlider class]]){
UISlider *tempSlider = (UISlider *) current;
UIImage *stetchLeftTrack = [[UIImage imageNamed:@"bar_2.png"]
stretchableImageWithLeftCapWidth:5.0 topCapHeight:0.0];
UIImage *stetchRightTrack = [[UIImage imageNamed:@"bar.png"]
stretchableImageWithLeftCapWidth:5.0 topCapHeight:0.0];
[tempSlider setMinimumTrackImage:stetchLeftTrack forState:UIControlStateNormal];
[tempSlider setMaximumTrackImage:stetchRightTrack forState:UIControlStateNormal];
}
}
[volumeView addSubview:volumeslider];
//[controllsView addSubview:volumeView];
[volumeView sizeToFit];
volumeView.hidden = YES;
isValumeBarHidden = YES;
//Volume Slider created and added to the volumeview
}
