比较按钮值

Question

我在我看来有两个按钮。

[button1 setBackgroundImage:image1 forState:UIControlStateNormal]; 
[button2 setBackgroundImage:image2 forState:UIControlStateNormal]; 

如何比较这些按钮中的两个图像？ I'de尝试：

if (button1.imageView.image.CGImage == button2.imageView.image.CGImage) 
{ 
    NSLog(@"equal"); 
} 
else 
{ 
    NSLog(@"not equal"); 
} 

它不用于帮助 工作:(

任何意见 感谢Yayo

试试这个

if ([[button1 backgroundImageForState:UIControlStateNormal] isEqual:[button2 backgroundImageForState:UIControlStateNormal]])
