Question

Hi how can i retrieve image from specified image path in iphone. In my code is

- (void)imagePickerController:(UIImagePickerController *)UIPicker didFinishPickingImage:(UIImage *)info editingInfo:(NSDictionary *)dictionary
{
    imageView.image=info;
    [UIPicker dismissModalViewControllerAnimated:YES];
    NSLog(@"UImage path= %@",imageView.image);
    NSData* imageData = UIImagePNGRepresentation(imageView.image);
    NSString* imageName = @"MyImage.png";
    NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* documentsDirectory = [paths objectAtIndex:0];
    NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
    [imageData writeToFile:fullPathToFile atomically:NO];
    NSLog(@"Image path = %@",fullPathToFile);
}

When i select image, the image should be placed, it will successfully placed to uiimage view. And i got the image path.

When i execute the application in console it showed

Image path=document = /Users/rr-mac/Library/Application Support/iPhone Simulator/4.3/Applications/46C716D0-13E9-4DF2-BC46-F1071DFCE14C/Documents/MyImage.png

My image is stored in this specified path. Here how can i retrieve this image and placed to imageview. Anybody help me to give the code.

Thanks in Advance.

To retrieve the UIImage in directory path, you should use :

UIImage *image = [UIImage imageWithContentsOfFile:fullPathToFile];

Full Code :

NSString *imageName = @"MyImage.png";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
UIImage *image = [UIImage imageWithContentsOfFile:fullPathToFile];
self.imageView.image = image;
