Subview position on the parent view iPhone - iphone

Question

I m using a menu bar like this (using UIBUTTONS on an ImageView)
Now what I required to do is that when I click on each button a popover (subview) should come up like:
How can I do that?
My second question is that when i click on the same button or anywhere else on the view then the popover should get hide and if i click on another menu button popover should get hide from previous button and should be shown on other button...
My project is already created with UIviewcontroller, so i think it would be much difficult to include the tab bars
any help please ...
-(IBAction)buttonNotify:(id)sender{
popOver.frame = CGRectMake(173, 385, 88, 33);
[self.view addSubview:popOver];
}

Answer 1

In .h file of your ViewController declare
UIImageView *popupView`;
In .m file in initialisation initialise it, something like
popupView = [[UIImageView alloc] initWithImage:#"your_image.png"];
popUpView.frame = //some CGRect here//;
popUpView.hidden = YES;
[self.view addsubView:popupView];
[popupView release];
Also when you create your buttons you do it like this, yep?
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = //some CGRect here//;
btn.tag = 1; // here you can set numeric tag for all your buttons
[btn addTarget:self action:#selector(buttonHandler:)forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
[btn release]
And implement method
-(void)buttonHandler:(id)sender
{
//sender here is your button object
//so you can take it's tag or frame or something else to set frame of popupView
popUpView.frame = //some rect
popUpView.hidden = NO;
}
And you when you handle touch on your view, set
popupView.hidden = YES to hide it
Also you can add some animation.

menu1Btn.tag = 0;
menu2Btn.tag = 1;
....
-(IBAction)buttonNotify:(id)sender{
int tag = [sender tag];
[popOver removeFromSuperView];
if(tag ==0){
popOver.frame = CGRectMake(0, 385, 88, 33);
[self.view addSubview:popOver];
}
else if(tag ==1){
popOver.frame = CGRectMake(40, 385, 88, 33);
[self.view addSubview:popOver];
}
else if(tag ==2){
popOver.frame = CGRectMake(80, 385, 88, 33);
[self.view addSubview:popOver];
}
......
}
