[英]Can a UIButton response to touch event if it's position is out of its superview, but it is visible?
如果UIButton的位置不在其超级视图中但可见,则它可以对touch事件做出响应吗?
UIView *view01 = [[UIView alloc] initWithFrame:CGRectMake(0,0,200,200)];
UIButton *button01 = [UIButton buttonWithStyle:UIButtonType:UIButtonTypeRoundedRect];
[button01 addTarget:self action:@selector(testTouch:) forControlEvents:UIControlEventTouchUpInside];
button01.frame = CGRectMake(0, 200, 60, 40);
[view01 addSubview:button01];
- (void)testTouch:(id)sender{
NSLog(@"Touched.....");
}
......
您还需要将view01
添加到视图中。
