Answer 1

One of the reason of error "kcferrordomaincfnetwork error 303" when you are calling a POST method as GET.

Answer 2

A 303 error is a redirect error.
You might want to check out the automatic handling of redirects with NSURLConnection:
https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/Articles/RequestChanges.html
If you'd like to handle it manually, the redirect url is in the response's 'Location' header. Here's how you can grab it in your connection:didReceiveResponse delegate method.
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
// ... if the response status is 303 ...
if ([response respondsToSelector:#selector(allHeaderFields)]) {
NSString* location = [[httpResponse allHeaderFields] valueForKey:#"Location"];
// do whatever with the redirect url
}
}
You coul also try urlEncoding your url including the data. Try what happens if you just call the following URL: http://quantuminfoways.com/crossfit_wodgenius/webservice/sync.php?udid=123&new=yes&uid=45&data=%20%7B%20createwod%20=%20%7B%20deletedcreatewod%20=%20(%20);%20newcreatewod%20=%20(%20);%20%7D;%20favorite%20=%20%7B%20deletedfavorite%20=%20(%20);%20newfavorite%20=%20(%20);%20%7D;%20gym%20=%20%7B%20deletedgym%20=%20(%20);%20newgym%20=%20(%20);%20%7D;%20workoutlog%20=%20%7B%20deletedworkoutlog%20=%20(%20);%20deletedworkoutlogtime%20=%20(%20);%20newworkoutlog%20=%20(%20);%20%7D;%20%7D
