如何比较UIColors？ [英] How to compare UIColors?

问题描述

我想检查UIImageView上的背景颜色集。我试过：

  if（myimage.backgroundColor == [UIColor greenColor]）{
 ...} 
 else {
 ...} 
  

即使我知道颜色是绿色，它总是落入else部分。

此外，是否有一种方法在调试控制台输出当前颜色。 p>

  p [myimage backgroundColor] 
  

b $ b

和

  po [myimage backgroundColor] 
  
解决方案
您尝试过<$ p> 
 c $ c> [myColor isEqual：someOtherColor] ？
 
I'd like to check the color set for a background on a UIImageView.  I've tried:
if(myimage.backgroundColor == [UIColor greenColor]){
...}
else{
...}
but that doesn't work, even when I know the color is green, it always falls into the else part.

Also, is there a way to output the current color in the debug console.
p [myimage backgroundColor]
and
po [myimage backgroundColor]
don't work.
解决方案
Have you tried [myColor isEqual:someOtherColor] ?
