loading a image from documents directory in iPhone

Question

I want to load a image to UIImageView from my app documents library. I am trying to use the following code but it is not working.

UIImageView *background = [[[UIImageView alloc] initWithFrame:CGRectMake(3, 10, 48, 36)] autorelease];

[background setImage:[[UIImage imageAtPath:[[NSBundle mainBundle] pathForResource:@"Thumbnail-small" ofType:@"jpg" inDirectory:@"/Users/nbojja/Library/Application Support/iPhone Simulator/User/Applications/60C2E4EC-2FE0-4579-9F86-08CCF078216D/Documents/eb43ac64-8807-4250-8349-4b1f5ddd7d0d/9286371c-564f-40b4-99bd-a2aceb00a6d3/9"]]] retain]];

can someone help me with doing this. thanks...

Answer 1

If you really want to load an image from your app's documents folder, you could use this:

NSArray *sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
NSString *docDirectory = [sysPaths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:@"%@/Thumbnail-small.jpg", docDirectory];
background.image = [[[UIImage alloc] initWithContentsOfFile:filePath] autorelease];

However, as pointed out by others here, you probably want to load it from your app bundle, in which case either of these will work:

background.image = [UIImage imageNamed:@"Thumbnail-small.jpg"];

or

NSString *path = [[NSBundle mainBundle] pathForResource:@"Thumbnail-small" ofType:@"jpg"];
background.image = [UIImage imageWithContentsOfFile:path];

Answer 2

NSString *docPath = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath=[NSString stringWithFormat:@"%@/image.png",docPath];

BOOL fileExists=[[NSFileManager defaultManager] fileExistsAtPath:filePath];

if (!fileExists)
    NSLog(@"File Not Found");
else
    image = [UIImage imageWithContentsOfFile:filePath];
