我要评论场景
橙色view添加在蓝色view上，满足点击超出蓝色view部分可以响应事件
实现思路
重写底部蓝色view的hittest方法，从最上层依次遍历子控件，判断触摸点是否在子控件上，在的话就返回子控件的hittest方法，不在就返回self
完整代码
#import "viewcontroller.h"
#import "botview.h"
@interface viewcontroller ()
@property(strong, nonatomic) botview *botview;
@property(strong, nonatomic) uiview *topview;
@end
@implementation viewcontroller
- (void)viewdidload {
[super viewdidload];
self.view.backgroundcolor = [uicolor whitecolor];
// do any additional setup after loading the view.
self.botview = [botview new];
self.topview = [uiview new];
[self.view addsubview:self.botview];
[self.botview addsubview:self.topview];
self.botview.frame = cgrectmake(100, 100, 100, 100);
self.topview.frame = cgrectmake(0, 0, 50, 200);
self.botview.backgroundcolor = [uicolor linkcolor];
self.topview.backgroundcolor = [uicolor orangecolor];
uitapgesturerecognizer *tap = [[uitapgesturerecognizer alloc]initwithtarget:self action:@selector(topviewclick:)];
[self.topview addgesturerecognizer:tap];
}
- (void)topviewclick:(uitapgesturerecognizer *)tap {
nslog(@"点击了顶部view");
}
@endbotview代码
#import "botview.h"
@implementation botview
- (uiview *)hittest:(cgpoint)point withevent:(uievent *)event{
int count = (int)self.subviews.count;
for (int i=count-1; i>=0; i--) {
uiview *subview = self.subviews[i];
//点击事件作用在子控件上面，返回点击点
cgpoint ispoint = [self convertpoint:point toview:subview];
uiview *subv = [subview hittest:ispoint withevent:event];
if (subv) {
return subv;
}
}
return self;
}
