Question

Im building a custom UIView similar to UIPopover view , simply I subclass the UIView class and build the stuff of controls and events inside .. to show this view I assign the superView through My sub Class datasource like this

    if ([dataSource respondsToSelector:@selector(containerView)]) 
        superView = [dataSource containerView];

and to show it I have a function doing that like this

- (void) showPopOverFromRect : (CGRect) rect
{
    CGSize popSize = self.frame.size;

    float yPoint;

    if(ntPopOverDirection == NTPopOverArrowDirectionUP)
        yPoint = rect.origin.y + 10;
    else
        yPoint = rect.origin.y - 10;

    self.frame = CGRectMake(rect.origin.x - popSize.width, yPoint , popSize.width, popSize.height);

    [superView addSubview:self];
}

so My Question .. how can i dismiss this view (remove it) if the user tap AnyWhere on the superView just like the UIPopOverController ?

Answer 1

You could place a UIButton below your new UIView that is clear. When this new button is pressed, it dismisses your view and removes itself from superview.

Something like:

- (void) showPopOverFromRect : (CGRect) rect
{
    CGSize popSize = self.frame.size;

    float yPoint;

    if(ntPopOverDirection == NTPopOverArrowDirectionUP)
        yPoint = rect.origin.y + 10;
    else
        yPoint = rect.origin.y - 10;

    self.frame = CGRectMake(rect.origin.x - popSize.width, yPoint , popSize.width, popSize.height);

    UIButton *dismissButton = [UIButton buttonWithType:UIButtonTypeCustom];
    dismissButton.backgroundColor = [UIColor clearColor];
    dismissButton.frame = [[UIScreen mainScreen] bounds];
    [dismissButton addTarget:self.delegate action:@selector(dismissPopover) forControlEvents:UIControlEventTouchUpInside];
    [superview addSubview:dismissButton];

    [superView addSubview:self];
}

You’d have to set up the view to set it’s superview as a delegate that receives the message to dismiss the popover, though.
