比較按鈕值

Question

我在我看來有兩個按鈕。

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

如何比較這些按鈕中的兩個圖像？ I'de嘗試：

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

它不用於幫助 工作:(

任何意見 感謝Yayo

試試這個

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