我将UIButton子类化,我想要的是将按钮类型设置为Round Rect.
@H_301_2@Button.h
@interface Button : UIButton {}
- (void)initialize;
@end
@H_301_2@Button.m
@implementation Button
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self initialize];
}
return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if(self){
[self initialize];
}
return self;
}
- (void)initialize
{
self.titleLabel.font = [UIFont systemFontOfSize:20];
self.titleLabel.textColor = [UIColor redColor];
self.titleLabel.textAlignment = UITextAlignmentCenter;
//[UIButton buttonWithType:UIButtonTypeRoundedRect];
}
@end
@H_301_2@在这里我尝试[UIButton buttonWithType：UIButtonTypeRoundedRect],但它不工作.任何人都可以建议如何使其发挥作用？
@H_301_2@我知道在许多以前的帖子中已经说过,SubBlassing UIButton是不推荐的,但事实上,在开发人员的文档中没有提到没有子类化它.
解决方法
您可能会发现CocoaBuilder的线程
How to subclass UIButton?的讨论有帮助,特别是
Jack Nutting’s suggestion to ignore the buttonType：
@H_301_2@Note that this way the buttonType isn’t explicitly set to anything,which probably means that it’s UIButtonTypeCustom. The Docs don’t seem to actually specify that,but since that’s the 0 value in the enum,that’s likely what happens (and that seems to be the observable behavior as well)
