Recently i faced a problem while using AFNetworking’s UIImageView+AFNetworking category.
I was making a image editor but the issue was when i used to post the image to my file server after editing the URL send to me of the edited image was same as that of previously unedited image. and when i used this url with
– (void)setImageWithURL:(NSURL *)url method i used to get the old unedited image which was there in cache.
so here is my solution.
1.take a global flag and set it to YES when you are using edited image url
2. Then in – (void)setImageWithURL:(NSURL *)url
placeholderImage:(UIImage *)placeholderImage method of UIImageView+AFNetworking
– (void)setImageWithURL:(NSURL *)url
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request addValue:@”image/*” forHTTPHeaderField:@”Accept”];
[self setImageWithURLRequest:request placeholderImage:placeholderImage success:nil failure:nil];
add the red code you will thus not receive the cached image for the edited image.
I have made a UIImageview category which explicitly provides this facility and works on the same principle as AFNetworking use and contribute as per your wish link
