How to add a rounded rectangle shape (or Box) in iphone interface?

Question

I want to add a rounded rectangle shape in iphone interface but the iphone library doesn't have that object. How do i do it?

Answer 1

You create an UIView subclass, in which you

#import <QuartzCore/QuartzCore.h>

and set its layer's cornerRadius property in code to a certain amount:

self.layer.cornerRadius = 5;
self.clipsToBounds = YES;

If you like you could create a property of your object, say roundedCornerRadius, and listen to its changes using KVO, in a code fragment similar to

[self addObserver: self forKeyPath:@"roundedCornerRadius" options:0 context:nil];

//implement in your UIView subclass
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object                 
         change:(NSDictionary *)change context:(void *)context
{
    if ([keyPath isEqual: @"roundedCornerRadius"])
               self.layer.cornerRadius = roundedCornerRadius;
}

Create rounded rectangle image of your interest. you can add this image to different UI Controls.

Answer 3

luvieere's answer worked for me.

Created a UIView subclass to hold the subviews i need to round the corners of. (I used IB).

Set that view to be the view of a UIViewController.

Overloaded viewDidLoad in the view controller to call a custom "viewDidLoad" method in the custom view.

That's where I set the corner radius for the subviews that need rounded corners.
