How to post message to Twitter from iPhone App

Step 1: Create a new application of Twitter from app registration and you will see the information as below.

It contains two key values we will need.

Consumer key

uc5Ag3Oog5Ot3lWtt4w91Q

Consumer secret

ZFcLlWfQEq5poFDpFuTRHAVdHWPVctQYu6wXM2qpTQ

Step 2: Download Twitter SDK

Step 3: Add Twitter SDK into your project.

Step 4: Add libxml2.dylib into Framework

Step 5: Add $(SDKROOT)/usr/include/libxml2 in "Header Search Paths"

Step 6: Replace key values with previous what we got in TwitterControl.m

#define kOAuthConsumerKey @"uc5Ag3Oog5Ot3lWtt4w91Q"

#define kOAuthConsumerSecret @"ZFcLlWfQEq5poFDpFuTRHAVdHWPVctQYu6wXM2qpTQ"

Step 7: Integrate Twitter SDK with your project

• Add #import "TwitterControl.h" and TwitterControlProtocol in xxxx.h
• Implement TwitterControlProtocol

-(void)didPostComplete:(TwitterControl *)control success:(BOOL)result

{

    [control autorelease];

}

• Post message to twitter

[TwitterControl postMessage:self msg:@"your message"];
