Question

I am using AFnetworking library to post data on server.

Following is my code to post data on server.

- (void) callLoginAPI:(NSDictionary *)dictProfil         


        

Answer 1

The error says it all: you got a 400 response from the server, meaning that what you sent was either not formatted properly, or the server just couldn't understand it.

Answer 2

Please add this line to your code, i hope it help you.

manager.requestSerializer = [AFHTTPRequestSerializer serializer];

Answer 3

I had experienced the same issue. In my case its only for upload Image with larger size. Our server has limited with max.upload size. I resized the image and uploaded, and the issue is gone.

You can resize the image with:

+ (UIImage*)imageWithImage:(UIImage*)image
              scaledToSize:(CGSize)newSize;
{
    UIGraphicsBeginImageContext( newSize );
    [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}
