//// 改变滑条的宽度
- (CGRect)trackRectForBounds:(CGRect)bounds {
returnbounds;
}
//改变宽度后，滑到右边会出现直角的多余的情况，以下宽度加20就是完整覆盖
- (CGRect)thumbRectForBounds:(CGRect)bounds trackRect:(CGRect)rect value:(float)value{
rect.origin.x= rect.origin.x-10;
rect.size.width= rect.size.width+20;
return CGRectInset([super thumbRectForBounds:bounds trackRect:rect value:value],10,10);
}
