Question

I’m using the Custom Picker by ray, when I press a button a picker is pop-ups then when image is chosen it will dismiss the picker and displayed the image in UIImageView. I put in the viewWillAppear but when I go to another ViewController the image chosen disappears. How to maintain the chosen in UIImageView to be displayed even after going to different View Controllers, only will it change if another image is chosen again.

- (void)viewWillAppear:(BOOL)animated {

    secondView.image = _imagePicker.selectedImage;
}

- (IBAction)chooseCustomImageTapped:(id)sender {
    _imagePicker = [[CustomImagePicker alloc] init];
    _imagePicker.title = @"Choose Custom Image";
   for(int i = 0; i <= 10; i++) 
    { 
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDir = [paths objectAtIndex:0];
        NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"Images%d.png", i]]; 

        if([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]){ 
            [_imagePicker addImage:[UIImage imageWithContentsOfFile:savedImagePath]]; 

        } 
    } 
     [self presentModalViewController:_imagePicker animated:NO];
}

I think you should take your image in UIImage object just after selection done UIImage *image = _imagePicker.selectedImage;, and retain it till next change. Then set that image to your image view secondView.image = image;.
