Adding Custom UIButton To subView - iphone

Question

I have subview which it initiated by touch on the UIbutton in the main view.
Once the subview pops up it displays a label with the info I provided. This all works. I just need an UIbutton to show up so I can then set it up to dismiss the subview and go back to the main view. i have searched all over and have found nothing that helps.
Here is what my code in my .m file looks like:
////Button that Displays Subview with Its Label and Button
- (IBAction)showInfo:(id)sender
/////UI Subview
{UIView *mySubview = [[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 480)];
[self.view addSubview:mySubview];
mySubview.backgroundColor = [UIColor blackColor];
mySubview.alpha = .7f;
//////Label in SubView
{UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 300, 50)];
label.text = #"Here is info";
label.textColor = [UIColor whiteColor];
label.backgroundColor= [UIColor clearColor];
[self.view addSubview:label];
////Button in Subview
//create the button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:#"button-info-x.png"] forState:UIControlStateNormal];
//set the position of the button
button.frame = CGRectMake(120, 252, 68, 68);
//add the button to the view
[self.view addSubview:button];
Now I just need to add an action to the UIButton to dismiss the Subview?

Answer 1

First Take IBOutlet of subView and add it to the main View.
IBOutlet UIView *subView;
Then, add UIButton to the SubView like this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//set the position of the button
button.frame = CGRectMake(0, 0, 100, 30);
//set the button's title
[button setTitle:#"Click Me!" forState:UIControlStateNormal];
[btnMenu addTarget:self action:#selector(your MethodName:) forControlEvents:UIControlEventTouchUpInside];
//add the button to the view
[subView addSubview:button];
Then,
-(IBAction)your MethodName:(id)sender {
}
In Above Method Remove SubView from Main View.

Answer 2

If you're simply looking to set an image for a UIButton instead of a title, you're looking for the - (void)setImage:(UIImage *)image forState:(UIControlState)statemethod.
You should check the UIButton reference for more info.

Answer 3

Add Target to the custom button
{
.....
[button addTarget:self action:#selector(your dismiss:) forControlEvents:UIControlEventTouchUpInside];
.......
}
-(IBAction)your dismiss:(id)sender
{
// write the dismissal code here
}
