Question

这开始是一个简单的问题，但我无法解决它。我已经将UIButton（我知道，有争议）分类，但我似乎无法让它正常工作。我的UIButton子类看起来像这样：

·H

@interface SocialButton : UIButton 

 @property (nonatomic, strong) CustomClass *cust;

 - (id)initWithObject:(CustomClass *)custom andFrame:(CGRect)frame; 

@end

的.m

@implementation SocialButton

@synthesize custom=_custom;

 - (id)initWithObject:(CustomClass *)custom andFrame:(CGRect)frame; 
 {
   self = [self initWithFrame:frame];
   if (self) 
   {        
     [self addTarget:self action:@selector(buttonTouchUpInside:)  forControlEvents:UIControlEventTouchUpInside];
     self.backgroundColor = [UIColor blueColor];
     self.cust = custom;
   }

   return self;
  }

@end

稍后，当我尝试从这个类创建一个按钮时，如下所示：

 SocialButton *social = [[SocialButton alloc] initWithObject:object andFrame:frame];

它似乎不起作用。有什么建议吗？

好像忘了给super打电话。变化：

self = [self initWithFrame:frame];

为：

self = [super initWithFrame:frame];

Subclassed UIButton似乎没有初始化
