試試這個

可以在使用下面的代碼UIImagePickerControllerDelegate委託執行

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 

//obtaining saving path 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"latest_photo.png"]; 

//extracting image from the picker and saving it 
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
if ([mediaType isEqualToString:@"public.image"]){ 
    UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage]; 
    NSData *webData = UIImagePNGRepresentation(editedImage); 
    [webData writeToFile:imagePath atomically:YES]; 
} 
}
