How to resave UIImage to the same path - ios

Question

I have an UIImage that is getting captured using the device camera, After the image is captured I am saving the UIImage like this,
-(void)onCapture:(UIImage *)image {
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
NSFileManager *filemanager = [NSFileManager defaultManager];
NSString *pathToImage = [NSTemporaryDirectory() stringByAppendingPathComponent:#"my_photo_001.jpg"];
[filemanager createFileAtPath:pathToImage contents:imageData attributes:nil];
NSURL *imageFileUrl = [NSURL fileURLWithPath:pathToImage];
[self.delegate onDone:imageFileUrl];
}
After the NSURL is passed to the delegate the delegate then passes this NSURL to an image editing view controller, I am passing the UIImage as well as the NSURL to the editing view controller, Once someone is done editing I want to override the UIImage stored at the NSURL with the edited UIImage so I am doing this,
NSData *imageData = UIImageJPEGRepresentation(self.editImage.image, 1.0);
NSString *pathToImage = [pathOfCapturedImage absoluteString];
[imageData writeToFile:pathToImage atomically:YES];
NSURL *imageFileUrl = [NSURL URLWithString:pathToImage];
Where pathOfCapturedImage is the variable I am passing to my edit view controller.
However when I am opening the image after saving it opens up the unedited image, Where am I going wrong?

Answer 1

You can try delete the old file first, and the write the new one;
[[NSFileManager defaultManager] removeItemAtPath:filePath error:&error];

Answer 2

First delete old exist image then write on the same path.
NSString* imagePath = #"image path"; // get path of old image.
NSData *imgData = UIImageJPEGRepresentation(self.editImage.image, 1.0); // get data of edited image. please make sure if edited image is not nil.
if ([[NSFileManager defaultManager] fileExistsAtPath:imagePath]) // check existence of old image, If yes then delete it.
{
[[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];
}
if (imgData)
[imgData writeToFile:imagePath atomically:YES];
