Question

I am facing one problem. I have a directory named as Album under my Supporting Files group. In this directory I have some images. In my image editing app I want to save my edited images in my album directory. I tried to save the image in my album directory by using the following code

NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSString *albumPath = [bundleRoot stringByAppendingString:@"/Album"];
NSString *savedImagePath = [bundleRoot stringByAppendingPathComponent: @"newImage11.jpeg" ]; UIGraphicsBeginImageContext(drawImage.image.size); 
CGContextRef ctx = UIGraphicsGetCurrentContext();
 [drawImage.layer renderInContext:ctx]; 
UIImage *editedImage = UIGraphicsGetImageFromCurrentImageContext();
NSData *editedImageData = UIImageJPEGRepresentation(editedImage, 1.0); UIGraphicsEndImageContext(); 
[editedImageData writeToFile:savedImagePath atomically:YES];

Here drawImage is the IBOutlet of UIImageView which holds the image.This code saved a file newImage11.jpeg in my album directory which has a size also. but when I retrieve the image from album directory it gives me a blank image. I used the following code to retrieve the image

NSString *img = [onlyJPGs objectAtIndex:currentIndex+numberToAdd]; 
UIImage *tempImage = [UIImage imageNamed:img]; 
imageButton.tag = img; 
[imageButton setImage:tempImage forState:UIControlStateNormal]; 
[imageButton addTarget:nil action:@selector(goToEdit:) forControlEvents:UIControlEventTouchUpInside]; 
currentIndex+=numberToAdd;

onlyJPGs is an array which holdes the name of all images contained in the Album directory. I am sure that my app is saving the image in Album directory because when I list the contents of Album directory in ImageEditing.app by using terminal it shows me the newImage11.jpeg file. Any kind of help would be appreciable.

Issue is just simple you are trying to save edited image into bundle.Actually application bundle is “Read-Only”. For this kind of Read and Write access you can use either document directory or Library.
You can get document directory path by following snippet of code.

NSString *path=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
