Setting up a subclass for UIButton to handle look-and-feel - iphone

Question

I have a AuthButtons.h header:
#import <UIKit/UIKit.h>
#interface AuthButtons : UIButton
#property (nonatomic, weak) UIColor *backgroundColor;
#end
The implementation AuthButtons.m class is as follows:
#import "AuthButtons.h"
#implementation AuthButtons
- (void)setBackgroundColor:(UIColor *)backgroundColor
{
backgroundColor = [UIColor blueColor];
}
- (UIColor *)backgroundColor
{
return [UIColor whiteColor];
}
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
Then in my viewcontroller.m class I have:
#interface ViewController ()
#property (nonatomic, weak) AuthButtons *registerButton;
#end
...
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
_registerButton = [AuthButtons buttonWithType:UIButtonTypeSystem];
[_registerButton setTitle:#"Register" forState:UIControlStateNormal];
[_registerButton setBackgroundColor:[UIColor whiteColor]];
_registerButton.frame = CGRectMake(0.0, 0.0, self.screenWidth / 2.0, 100.0);
[_registerButton addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
}
It keeps crashing when I try to create the button. What am I missing?

Answer 1

Your button is weak and not added as a subview so its deallocated right away

Answer 2

Use strong instead of weak(i always use strong type when using buttons in ARC enabled class,not sure whether its a bad habbit :-))
#property (nonatomic, strong) AuthButtons *registerButton;
and add it as your subview([self.view addSubview:_registerButton]).Hope you have implemeted the function called -(void)buttonPressed:(id )sender in your class.
