i using button multiple image view, example after clicking on button image of button change used that:

if(button.imageview.image ==[uiimage imagenamed:@"addfriendpressed.png"]){       } 

this working in ios 7 , not ios8. solutions please?

- (bool)image:(uiimage *)image1 isequalto:(uiimage *)image2 {     nsdata *data1 = uiimagepngrepresentation(image1);     nsdata *data2 = uiimagepngrepresentation(image2);      return [data1 isequal:data2]; } 

use isequal :

if([button.imageview.image isequal:[uiimage imagenamed:@"addfriendpressed.png"]]){     } 

or

if([[button backgroundimageforstate:uicontrolstatenormal] isequal: [uiimage imagenamed:@"addfriendpressed.png"]]){     } 

or add category uiimageview
