how to get the name of the image?

There is no way to do it using UIImage. One way to solve this problem if you really need it would be subclassing UIImage and adding a name attribute:

UINamedImage.h

#import <Foundation/Foundation.h>


@interface UINamedImage : UIImage {

}

@property (nonatomic, readonly) NSString * name;

-(UINamedImage *) initWithName:(NSString *)name;

@end

UINamedImage.m

@implementation UINamedImage

@synthesize name = _name;

-(UINamedImage *) initWithName:(NSString *)name {
    UIImage * image = [UIImage imageNamed:name];
    self = [super initWithCGImage:image.CGImage];
    _name = [name retain];
    return self;
}

-(void) dealloc {
    [_name release];
    [super dealloc];
}

@end

there is the way, this code will help you out

    NSString *imgName = [self.imgView1st image].accessibilityIdentifier;

    NSLog(@"%@",imgName);

    [self.imgView2nd setImage:[UIImage imageNamed:imgName]];

IIRC, you can't. Once the image is initialized, it doesn't take it's name along on the ride. You'd have to store it in a separate member instead. HTH Marcus

There is no name. All you have is a UIImage object. That's it.
