UISlider自定义

Question

我正在定制我的UISlider,如下所示:

[[UISlider appearance] setMinimumValueImage:[[UIImage imageNamed:@"slider_minimum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)]];
[[UISlider appearance] setMaximumValueImage:[[UIImage imageNamed:@"slider_maximum.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)]];

这有点奏效,这是结果:
