删除 UIPopoverController 的边框

发布于 2024-10-12 05:29:23 字数 207 浏览 9 评论 0原文

我有一个要求，我必须为 UIPopoverController 的弹出视图显示自定义边框，而不是默认的“黑色主题”边框。是否可以？

我无法使用默认的黑色边框，因为它不适合应用程序的颜色主题。

SDK 中没有提供执行此操作的规定。我也用谷歌搜索看看其他人是否遇到过这个问题以及他们是否已经解决了它，但没有运气！

等待建议。

谢谢，拉杰

通过使用 UIView 以及覆盖主 rootViewController 视图中的 hitTest 来查看触摸点是否在该视图之外解决了这个问题。如果是，则将使用该事件来关闭新的弹出窗口，否则该事件将被转发到新的弹出窗口。

添加popview作为子视图，代码是：

//!you must define the dimBackgroundView and set view in head file firstly, 

//action for a button,to add set view as a subview
 - (IBAction)openSetting:(id)sender {

    if(!dimBackgroundView)
    {
       dimBackgroundView = [[UIView alloc] initWithFrame:self.view.bounds];
    }
    dimBackgroundView.backgroundColor = [[UIColor clearColor] colorWithAlphaComponent:0.0];

    [self.view addSubview:dimBackgroundView];

    SettingViewController *set = [[SettingViewController alloc]initWithNibName:nil bundle:nil];
    [set.view setFrame:CGRectMake(120, 50, 400, 600)];
    self.setView = set;

    //add shadow
    set.view.layer.shadowOffset = CGSizeMake(3, 3);
    set.view.layer.shadowColor = [UIColor colorWithRed:70.0/255.0 green:70.0/255.0 blue:80.0/255.0 alpha:1.0].CGColor;
    set.view.layer.shadowOpacity = 0.8;

    [self.view addSubview:set.view];
}
//check touch position, if touch position is outside of setview, remove it from superview
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event{
    UITouch *touch = [[event allTouches] anyObject];
    if ([self.setView.view superview] && self.dimBackgroundView == touch.view) {
        [self.dimBackgroundView removeFromSuperview];
        [self.setView.view removeFromSuperview];
    }
}

add popview as subview, code is:

//!you must define the dimBackgroundView and set view in head file firstly, 

//action for a button,to add set view as a subview
 - (IBAction)openSetting:(id)sender {

    if(!dimBackgroundView)
    {
       dimBackgroundView = [[UIView alloc] initWithFrame:self.view.bounds];
    }
    dimBackgroundView.backgroundColor = [[UIColor clearColor] colorWithAlphaComponent:0.0];

    [self.view addSubview:dimBackgroundView];

    SettingViewController *set = [[SettingViewController alloc]initWithNibName:nil bundle:nil];
    [set.view setFrame:CGRectMake(120, 50, 400, 600)];
    self.setView = set;

    //add shadow
    set.view.layer.shadowOffset = CGSizeMake(3, 3);
    set.view.layer.shadowColor = [UIColor colorWithRed:70.0/255.0 green:70.0/255.0 blue:80.0/255.0 alpha:1.0].CGColor;
    set.view.layer.shadowOpacity = 0.8;

    [self.view addSubview:set.view];
}
//check touch position, if touch position is outside of setview, remove it from superview
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event{
    UITouch *touch = [[event allTouches] anyObject];
    if ([self.setView.view superview] && self.dimBackgroundView == touch.view) {
        [self.dimBackgroundView removeFromSuperview];
        [self.setView.view removeFromSuperview];
    }
}
