Passing image between views - ios

Question

I am solving this issue about 2 weeks and only be able to pass string, not image.
I store the image from camera or from library in this method.
-(IBAction)saveAction:(id)sender
{
Tricks *trick = [[Tricks alloc]init];
trick.trickName = self.trickLabel.text;
trick.trickPhoto = [[UIImageView alloc] initWithFrame:CGRectMake(0, 356, 320, 305)];
trick.trickPhoto.image = self.ImagePhoto.image;
[[Tricks trickList]addObject:trick];
}
In tableViewClass I store the values into properties of detailView
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([[segue identifier] isEqualToString:#"detailTrick"]){
NSIndexPath *indexPath = nil;
indexPath = [self.tableView indexPathForSelectedRow];
DetailViewController *detailViewController = [segue destinationViewController];
Tricks *trick = [[Tricks trickList] objectAtIndex:indexPath.row];
detailViewController.trickPhoto = [[UIImageView alloc]initWithFrame:CGRectMake(0, 358, 200, 200)];
detailViewController.fileText = trick.trickName;
detailViewController.trickPhoto = trick.trickPhoto;
//object = [Tricks trickList][indexPath.row]
}
}
Text showed up every time without problems, but there is no image in detailViewController.Thanks for help.
viewDidLoad of detailViewController
[super viewDidLoad];
[self.detailButton setTitle:[NSString stringWithFormat:#"%#",_fileText] forState:UIControlStateNormal];
[self.trickPhoto setImage:_trickPhoto.image];

Answer 1

First off, trickPhoto within the Trick class should be a UIImage, not a UIImageView. Models shouldn't know anything about views such as frames, etc so right now you're violating the MVC design pattern.
Then it'd be:
- (IBAction)saveAction:(id)sender
{
Tricks *trick = [[Tricks alloc] init];
trick.trickName = self.trickLabel.text;
trick.trickPhoto = self.ImagePhoto.image;
[[Tricks trickList] addObject:trick];
}
The better way of doing this would be to create a Trick property within DetailViewController and just pass the whole trick into the view controller.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"detailTrick"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
DetailViewController *detailViewController = [segue destinationViewController];
Tricks *trick = [[Tricks trickList] objectAtIndex:indexPath.row];
NSLog(#"Make sure trick isn't nil: %#", trick);
detailViewController.trick = trick;
}
}
Then you'd just populate it with:
[super viewDidLoad];
[self.detailButton setTitle:[NSString stringWithFormat:#"%#", self.trick.trickName] forState:UIControlStateNormal];
[self.trickPhoto setImage:self.trick.trickPhoto];
