// 在view中重写以下方法,其中self.button就是那个希望被触发点击事件的按钮
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
UIView *view = [super hitTest:point withEvent:event];
if (view == nil) { // 转换坐标系
CGPoint newPoint = [self.button convertPoint:point fromView:self];
// 判断触摸点是否在button上
if (CGRectContainsPoint(self.button.bounds, newPoint)){
view = self.deleteButton;
}
}
return view;
}
