Remove border for UIPopoverController

问题

I have a requirement where in I have to display a custom border for UIPopoverController's popover view instead of the default "Black theme" border. Is it possible?

I cannot use the default black border because it doesnt suite the application's color theme.

There is no provision in the SDK to do this. I have also googled to see if someone else have faced this problem and if they have solved it, but with no luck!

Awaiting suggestions.

Thanks, Raj

回答1:

Solved this by using UIView and also by overriding the hitTest in the main rootViewController's view to see if the touch point is outside that view. If so, the event will be consumed to dismiss the new popover, otherwise the event will be forwarded to the new popover.

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];
    }
}
