- 最low的办法，在button上加一个button
- 重写view方法
-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event;
这个方法就是穿你点击的那个点，判断是否在view上
需要添加一个view或者button的拓展类
@interface UIView(ChangeScope)
-(void)changeViewScope:(UIEdgeInsets)changeInsets;
@end
import "UIView+ChangeScope.h"
import <objc/runtime.h>
@implementation UIView (ChangeScope)
static char *changeScopeKey;
- (void)setChangeScope:(NSString *)changeScope
{
objc_setAssociatedObject(self, &changeScopeKey, changeScope, OBJC_ASSOCIATION_COPY_NONATOMIC);
}
- (NSString *)changeScope
{
return objc_getAssociatedObject(self, &changeScopeKey);
}
- (void)changeViewScope:(UIEdgeInsets)changeInsets
{
self.changeScope = NSStringFromUIEdgeInsets(changeInsets);
}
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
UIEdgeInsets changeInsets = UIEdgeInsetsFromString(self.changeScope);
if (changeInsets.left != 0 || changeInsets.top != 0 || changeInsets.right != 0 || changeInsets.bottom != 0) {
CGRect myBounds = self.bounds;
myBounds.origin.x = myBounds.origin.x + changeInsets.left;
myBounds.origin.y = myBounds.origin.y + changeInsets.top;
myBounds.size.width = myBounds.size.width - changeInsets.left - changeInsets.right;
myBounds.size.height = myBounds.size.height - changeInsets.top - changeInsets.bottom;
return CGRectContainsPoint(myBounds, point);
} else {
return CGRectContainsPoint(self.bounds,point);
}
}
@end
