IOS UISlider划不动问题解决
创建RLKShapeSlider文件，继承自：UISlider,创建两个slider即可完成处理
import "RLKShapeSlider.h"
static const CGFloat kSliderBound = 20.0;
@interface RLKShapeSlider ()
@property (nonatomic) CGRect lastBounds;
@end
@implementation RLKShapeSlider
-
(CGRect)trackRectForBounds:(CGRect)bounds {
return CGRectMake(bounds.origin.x, bounds.origin.y, bounds.size.width, MAX(bounds.size.height, 2.0));
} -
(CGRect)thumbRectForBounds:(CGRect)bounds trackRect:(CGRect)rect value:(float)value;
{rect.origin.x = rect.origin.x;
rect.size.width = rect.size.width;
CGRect result = [super thumbRectForBounds:bounds trackRect:rect value:value];
//记录下最终的frame
_lastBounds = result;
return result;
}
//检查是点击事件的点是否在slider范围内 -
(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {
//调用父类判断
BOOL result = [super pointInside:point withEvent:event];if (!result) {
//如果不在slider范围内，扩充响应范围
if ((point.x >= (_lastBounds.origin.x - kSliderBound)) &&
(point.x <= (_lastBounds.origin.x + _lastBounds.size.width + kSliderBound)) &&
(point.y >= -kSliderBound) &&
(point.y < kSliderBound)) {
//在扩充范围内
return YES;
}
}//否则返回父类的结果
return result;
}
