UITableViewCell.ImageView.image Compare UIImage

Question

I am comparing cell.imageView.image with UIImage as below code.

Please refer below Code

    UIImage *imgOne = [UIImage imageNamed:@"One"];

    if([customCell.imageView.image isEqual: imgOne]){
          NSLog(@"Right Image");
    }

While debugging, I write as po [customCell.imageView.image isEqual imgOne], but it always returns as 'nil'.

Can anyone tell me how to compare this or proper way to compare?

The method you used should work. That is the proper way to compare images. Your debugging result should return true or false, not nil, so something else must be wrong. Try logging imgOne and also customCell.imageView.image to see what they give (put that log just above the line with your if statement, wherever that is). — rdelmar, Oct 18 '14 at 16:16

Generally UIImageView can not store file name of image but it store only UIImage so, it is not possible to get file name of image which you add in UIImageView.

Thats way if you want to compare only image file name then it is not possible to compare it.

But If you want to compare two UIImage object then

UIImage *secondImage = [UIImage imageNamed:@"image.png"];

NSData *imgData1 = UIImagePNGRepresentation(self.imageView.image);
NSData *imgData2 = UIImagePNGRepresentation(secondImage);

BOOL isCompare =  [imgData1 isEqualToData:imgData2];
if(isCompare)
{
  NSLog(@"Image View contains image.png");
}
else
{
  NSLog(@"Image View doesn't contains image.png");
}

If you matain the "image one" as a member var.(1)
And set the cell's image this value.(2)
Then you can compare using those two pointers.(3)
See this code:

//1
self.imgOne  = [UIImage imageNamed:@"One"];  
//2  
customCell.imageView.image=self.imgOne   
//3  
if(customCell.imageView.image == self.imgOne)
   {}

so simple and quick. I think converting to nsdata is overkill – Vilém Kurz Dec 07 '15 at 13:49

Instead of Imageview I tried with Button

And than i Check as below

    if([cell.button.currentImage isEqual: [UIImage imagenamed:"Your Imagenem"]]){
NSLog(@"Right Image");

}

It works fine..

Thank you.
