UIImageView /UIImage Not Working - What Am I Doing Wrong? - iphone

Question

I am not getting my image working. Can anyone tell me what I am doing wrong here?
musclePicture is a string in format of picture.png
1st view:
NSString *muscleURL = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:#"musclePicture"];
specificExerciseTableViewController.muscleImage = [UIImage imageNamed:muscleURL];
2nd view:
detailViewController.muscleImage = self.muscleImage;
3rd view:
self.image = [[UIImageView alloc]initWithImage:muscleImage];
[image release];
Edit:
MusclesTableViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *muscleURL = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:#"musclePicture"];
specificExerciseTableViewController.muscleImage = [UIImage imageNamed:muscleURL];
}
SpecificExerciseTableViewController.h
#property (nonatomic, retain) UIImage *muscleImage;
SpecificExerciseTableViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
detailViewController.muscleImage = self.muscleImage;
}
DetailViewController.h
#property (nonatomic, retain) UIImage *muscleImage;
#property (nonatomic, retain) IBOutlet UIImageView *image;
DetailViewController.m
- (void)viewDidLoad
{
self.image.image = muscleImage;
}

Answer 1

Try by giving a frame to your UIImageView after:
self.image = [[UIImageView alloc]initWithImage:muscleImage];
[image setFrame:CGRectMake(0,0,50,50)];
[image release];

Answer 2

Try this code snippet:
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:[animal imageURL]]];
UIImage *animalImage = [[UIImage alloc] initWithData:imageData];
Assign it your UIImageView or UIImage.

Answer 3

I think you forgot to add image as subView to your view.
like this
[self.view addSubView:image];
or you are having a class variable that is connected to .xib file as an IBOutlet and you are reinitializing it using alloc and init, if that is the case then you have to do
self.image.image = [UIImage imageNamed: muscleImage];
