比较按钮值

Question

我认为我有两个按钮。

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

如何比较这些按钮中的两个图像？我试过了：

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

它不起作用：（。

任何建议？ 感谢帮助 Yayo

试试这个

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