Question

I’m trying to load a UIImage from the documents directory and set it to a UIImageView as per below:

NSString  *pngfile = [[MyUtil getLocalDirectory] stringByAppendingPathComponent:@"school.png"];
NSLog(@"%@", pngfile);
if ([[NSFileManager defaultManager] fileExistsAtPath:pngfile]) {
    NSData *imageData = [NSData dataWithContentsOfFile:pngfile];            
    UIImage *img = [UIImage imageWithData:imageData];
    [schoolImage setImage:img];
}

However, whenever I try the above, the image never loads. The image is in Documents/MyAppCustomDirectory/school.png. Is the above correct to load from that directory?

I also tried a few others: UIImage imageWithContentsOfFile, among other ways based on SO responses.

To get the documents directory you should use:

NSArray  *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir  = [documentPaths objectAtIndex:0];
NSString  *pngfile = [documentsDir stringByAppendingPathComponent:@"school.png"];

I’m not quite sure if you also need to append the ‘MyAppCustomDirectory’, but I don’t think so.
