UIImage* image;

    NSData* imageData = [[NSUserDefaults standardUserDefaults] objectForKey:@"image"];


    if (imageData == (id)[NSNull null] || imageData.length == 0) {
        NSLog(@"image data is %@",imageData);
        image = [UIImage imageNamed:@"defaultIcon.png"];
    }
    else {
        image = [UIImage imageWithData:imageData];

    }
