ios load an image from docDir into UIimagview - viewDidLoad - ios

Question

I have a group of images saved in my DOcuments folder of the app. I got it to save to that location, I am having trouble loading from that location.
I got the UIimageView working hardcoded with images I dragged to a folder in the project with the code below in the viewDidLoad() method and when i ran the simulator it appeared.
UIImageView *bottomPic = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"pants.png"]];
bottomPic.frame = CGRectMake(65, 279, 200, 250);
[self.view addSubview:bottomPic];
[bottomPic release];
However when I want to load the image from the Documents Directory nothing loads - Am confused and couldn't find any exact information to help me out on this situation.. This is currently what I have and when I run it doesn't throw any errors but no image appears. Am I missing something in my code? (I'm new to objective-c!)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"bottom1A2A6520-F556-436F-A1BC-D430223DC890-33098-00014708AE7E370F.png"]];
UIImage *image = [UIImage imageWithContentsOfFile:path];
UIImageView *bottomPic = [[UIImageView alloc] initWithImage:[UIImage imageNamed:path]];
bottomPic.frame = CGRectMake(65, 279, 200, 250);
[bottomPic setImage:image];
[self.view addSubview:bottomPic];
[bottomPic release];

Answer 1

A path is a path and an image is an image.
UIImage *image = [UIImage imageWithContentsOfFile:path];
UIImageView *bottomPic = [[UIImageView alloc] initWithImage:image];

Answer 2

Your code has a few issues. Try this:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = paths[0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"bottom1A2A6520-F556-436F-A1BC-D430223DC890-33098-00014708AE7E370F.png"];
UIImage *image = [UIImage imageWithContentsOfFile:path];
UIImageView *bottomPic = [[UIImageView alloc] initWithImage:image];
bottomPic.frame = CGRectMake(65, 279, 200, 250);
[self.view addSubview:bottomPic];
[bottomPic release];
Unrelated to the problem, you were needlessly using stringWithFormat:.
The real problem was creating the UIImageView with an unneeded image using imageNamed:.
If this doesn't work then verify that path actually represents a file that really exists in the Documents folder. Verify image isn't nil.
Also consider use ARC (automatic reference counting) to make your life a lot easier.
Update: It appears you needed NSDocumentDirectory instead of NSDocumentationDirectory.
