自定义UISlider

1 UIImage *minImage = [[UIImage imageNamed:@"slider_minimum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
2 UIImage *maxImage = [[UIImage imageNamed:@"slider_maximum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
3 UIImage *thumbImage = [UIImage imageNamed:@"thumb.png"];
4     
5 [[UISlider appearance] setMaximumTrackImage:maxImage forState:UIControlStateNormal];  // 
6 [[UISlider appearance] setMinimumTrackImage:minImage forState:UIControlStateNormal];
7 [[UISlider appearance] setThumbImage:thumbImage forState:UIControlStateNormal];

这将设置整个工程的UISlider外观。

1 UIImage *minImage = [[UIImage imageNamed:@"slider_minimum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
2 UIImage *maxImage = [[UIImage imageNamed:@"slider_maximum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
3 UIImage *thumbImage = [UIImage imageNamed:@"thumb.png"];
4     
5 [self.slider setMaximumTrackImage:maxImage forState:UIControlStateNormal];
6 [self.slider setMinimumTrackImage:minImage forState:UIControlStateNormal];
7 [self.slider setThumbImage:thumbImage forState:UIControlStateNormal];

这将修改本页的UISlider。
