iOS Storing image locally

[DennisBlah]

Hey all, I'm trying to store images locally for offline use.
The code below works fine, in simulator, but on a actual device (iPhone 5S on iOS7.1.2) it doesn't store the image to the documents folder

                NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                
                NSData *imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: [NSString stringWithFormat: @"%@images/%@/%@", theHost, theSub, theImageName]]];
                UIImage *image = [[UIImage alloc] initWithData: imageData];
                NSString *jpegFilePath = [NSString stringWithFormat:@"%@/%@/%@", [paths objectAtIndex:0], theSub, theImageName];
                
                NSData *data2 = [NSData dataWithData:UIImageJPEGRepresentation(image, 6.0f)];
                [data2 writeToFile:jpegFilePath atomically:YES];

However I'm doing the same thing with a html page, in same sub, and that works fine

NSString *filePath = [NSString stringWithFormat:@"%@/%@/%@/index.html", [paths objectAtIndex:0], theSub, pageName];
    
    // Download and write to file
    NSURL *downloadURL = [NSURL URLWithString: url];
    NSData *urlData = [NSData dataWithContentsOfURL:downloadURL];

    [urlData writeToFile:filePath atomically:YES];

p.s. before starting I am checking if the sub exists, also at the image, if not, then creating it.

Hopefully someone can help me out because I really don't understand this thing... In simulator it works fine :-(

---------
Sorry it was a stupid fault. At the image check it never met the if statement 😱

Cheers!😎

Commonly this problem is caused by the path being invalid. You need to print it out from that code.

Also, you should use the path utilities to build paths.
