can not setimage of uiimageview while pushing viewcontroller

Question

I am new on objective c and I am trying to set image of UIImageview while pushing viewcontroller I checked other answer and I did the same way they said it but its not working for me below is my code and i will explain other things in it

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    DetailViewController *svController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];



    UIImage *image = [UIImage imageNamed:@"default.png"];
    UIImageView* imageview = [[UIImageView alloc] initWithImage:image];


    id obj = [[mainArray valueForKey:@"image"] objectAtIndex:[indexPath row]];
    if ([obj isKindOfClass:[NSString class]])
    {




          NSLog(@" image%@",image); //print this image<UIImage: 0xaa70700>

         NSLog(@" image%@",svController.image); //print this  image(null)
        [[svController image] setImage: image];

         NSLog(@" image%@",svController.image);   //print this  image(null)


    }


    else     {
         NSLog(@" image%@",svController.image);

                  [[svController image] setImage: [[mainArray valueForKey:@"image"] objectAtIndex:[indexPath row]]];

              NSLog(@" image%@",svController.image);


    }


    [self.navigationController pushViewController:svController animated:YES];

    [svController release];
    svController = nil;

}

below is my detailviewcontroller

@interface DetailViewController : UIViewController{

    UIImageView *image;


}

@property (retain, nonatomic) IBOutlet UIImageView *image;

its connected to Xib and i have synthesized it

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.


    name.text = nameString;
    email.text = emailString;

     NSLog(@"%@",image); // print this <UIImageView: 0x9d73950; frame = (27 35; 204 181); autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x9db4050>>

}

its working perfectly when i send NSString and set them on my lable but not working for image it its so small thing but now i dont know what to do please help

Answer 1

hear is the simple way, i am showing the example that u can set image in detail view controller

in your master view controller

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 {
    if(indexPath.row == 0)//for 1st row
    {
       DetailViewController *detController = [[DetailViewController alloc]initWithNibName:@"DetailViewController" bundle:nil];
       detController.detailImage = [UIImage imageNamed:@"abc.png"];//setting the property for image
       [self.navigationController pushViewController:detController animated:YES];
       [detController release];//im doing without ARC
    }
    else if (indexPath.row == 1)
    {
       DetailViewController *detController = [[DetailViewController alloc]initWithNibName:@"DetailViewController" bundle:nil];
       detController.detailImage = [UIImage imageNamed:@"123.png"];
       [self.navigationController pushViewController:detController animated:YES];
       [detController release];//im doing without ARC
    }
}

and in your detail view controller

// .h file
@interface DetailViewController : UIViewController
{

}
@property (retain, nonatomic) IBOutlet UIImageView *ImageView;
@property (nonatomic, retain)UIImage * detailImage;//set a property for image that u are passing from master viewcontroller 
@end

//in .m file

@implementation DetailViewController
@synthesize detailImage;  //synthesise it

// and in viewDidload method 
- (void)viewDidLoad
{
   [super viewDidLoad];

  //set your passed image to image view
  self.ImageView.image = self.detailImage;   
}

---

Better would be just do like this:

[self.navigationController pushViewController:svController animated:YES];
if(yourImage) //got UIImage reference then only set it
   svController.yourImgView.image = yourImageHere

.................
<<Another code here>>
..............

Thats it....
