Profile Information

[obaidjawad]

Hi I tried to fetch the profile image using this block method

  [_twitter getUsersShowForUserID:nil orScreenName:username_twitter includeEntities:nil successBlock:^(NSDictionary *user){
           NSLog(@"%@",[user valueForKey:@"profile_image_url"]);
        }errorBlock:^(NSError *error) {
            NSLog(@"%@",[error localizedDescription]);
        }];

But the app crashes when I use it

Crash log:
-[TWRequest preparedURLRequest]: unrecognized selector sent to instance 0xaa382f0

I figured it out and that is because the method is compatible with iOS 6.0+ and it doesn't work for iOS 5
Could you please make it compatible with iOS 5?

Thank you for reporting this!

I cannot test on iOS 5 right now.

Please let me know it this commit does fix the issue.

Just ran across this issue my self, so glad there was already a response as was scratching my head.. not wanting to dig in.
Ok testing running ios 7 executes the TW code, which does not give a result at all..

flipping the > than sign in these two places ran the right code block, and yup code worked (ie followed someone on twitter) ... except none of the call back blocks worked (success or error)

#if (TARGET_OS_IPHONE) && (__IPHONE_OS_VERSION_MIN_REQUIRED > __IPHONE_6_0)
TWRequestMethod method = (httpMethod == 0) ? TWRequestMethodGET : TWRequestMethodPOST;
request = [[TWRequest alloc] initWithURL:url parameters:paramsWithoutMedia requestMethod:method];
#else
request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:httpMethod URL:url parameters:paramsWithoutMedia];
#endif

[request setAccount:self.account];

if(mediaData) {
    [request addMultipartData:mediaData withName:@"media[]" type:@"application/octet-stream" filename:@"media.jpg"];
}

self.completionBlock = completionBlock;
self.errorBlock = errorBlock;

// we use NSURLConnection because SLRequest doesn't play well with the streaming API

NSURLRequest *preparedURLRequest = nil;

#if TARGET_OS_IPHONE && (__IPHONE_OS_VERSION_MIN_REQUIRED > __IPHONE_6_0)
preparedURLRequest = [request signedURLRequest];
#else
preparedURLRequest = [request preparedURLRequest];
#endif
