I'm using FHSTwitterEngine to post a gif to twitpic. When I have a wifi or 3G connection on the iphone everything works fine. But I also want to implement some error handling for when there is no connection or when the upload failed. So for testing I put the iphone in airplane mode and try to upload to twitpic using the following method:
id returned = [[FHSTwitterEngine sharedEngine] uploadImageToTwitPic:gif
withMessage:@"message" twitPicAPIKey:@"key"];
but when I do that I immediately get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: 'data parameter is nil'
then xcode points to this line of code in the FHSTwitterEngine framework:
id parsedJSONResponse = removeNull([NSJSONSerialization JSONObjectWithData:responseData
options:NSJSONReadingMutableContainers error:nil]);
any ideas on how to solve this?
You could check for internet connectivity first.
Reachability *networkReachability = [Reachability reachabilityForInternetConnection];
NetworkStatus networkStatus = [networkReachability currentReachabilityStatus];
if (networkStatus == NotReachable) {
NSLog(@"There IS NO internet connection");
} else {
NSLog(@"There IS internet connection");
}
}
