ios7.1 setButtonImage（ setimage跟创建button不在一方法体中的情况）
在ios7.0及以前
+(id)getButton:(NSString *)selectImageName UnselectImageName:(NSString *)unselectImageName frame:(CGRect)frame
{
NDTSelectButton *button = [NDTSelectButton buttonWithType:UIButtonTypeCustom];
button.frame = frame;
button.selectImageName = selectImageName;
button.unSelectImageName = unselectImageName;
[button setBackgroundImage:[UIImage imageNamed:button.selectImageName] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:button.selectImageName] forState:UIControlStateHighlighted];
return button;
}
-(void)setIsSelected:(BOOL)isSelected
{
_isSelected = isSelected;
if (_isSelected)
{
[self setBackgroundImage:[UIImage imageNamed:self.selectImageName] forState:UIControlStateNormal];
[self setBackgroundImage:[UIImage imageNamed:self.selectImageName] forState:UIControlStateHighlighted];
}else
{
[self setBackgroundImage:[UIImage imageNamed:self.unSelectImageName] forState:UIControlStateNormal];
[self setBackgroundImage:[UIImage imageNamed:self.unSelectImageName] forState:UIControlStateHighlighted];
}
}
同时调用上述两个方法（setimage跟创建button不在一方法体中的情况），是可以正常给button添加图片和实现换图功能的 但是7.1就不行，只能在添加self.enabled = NO;
self.enabled = YES;
才能正常运行具体代码如下
+(id)getButton:(NSString *)selectImageName UnselectImageName:(NSString *)unselectImageName frame:(CGRect)frame
{
NDTSelectButton *button = [NDTSelectButton buttonWithType:UIButtonTypeCustom];
button.frame = frame;
button.selectImageName = selectImageName;
button.unSelectImageName = unselectImageName;
[button setBackgroundImage:[UIImage imageNamed:button.selectImageName] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:button.selectImageName] forState:UIControlStateHighlighted];
return button;
}
-(void)getSelectButton:(NSString *)selectImageName UnselectImageName:(NSString *)unselectImageName frame:(CGRect)frame
{
// NDTSelectButton *button = [NDTSelectButton buttonWithType:UIButtonTypeCustom];
self.frame = frame;
self.selectImageName = selectImageName;
self.unSelectImageName = unselectImageName;
NSLog(@"button.selectImageName%@---%@",self.selectImageName,self.unSelectImageName);
}
具体原因未知
