Question

I’m trying to create & use a very simple UIView subclass for a rectangle with rounded corners. I’ve created a new class as follows :

RoundedRect.h

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@interface RoundedRect : UIView
@end

RoundedRect.m

#import "RoundedRect.h"

@implementation RoundedRect

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        [[self layer] setCornerRadius:10.0f];
        [[self layer] setMasksToBounds:YES];
    }
    return self;
}
@end

I’m using iOS 5.1 with storyboards and have set the custom class property in the IB inspector window to ‘RoundedRect’, but when I run the app the rectangle still has square corners. Have I missed something obvious?

Thanks
Jonathan

Answer 1

The initWithFrame method is not called when the view is instantiated from a XIB file. Instead, the initWithCoder: initializer is called, so you need to perform the same initialization in this method.
