How to keep given password in mgtwitterengine api - iphone

Question

I want to keep password which is given by user in a variable. Where to get password value. I look in code but it is containing only username. I am using MGTwitterengine api in my application. Here is the function which is printing data on console.
-(void)setUsername:(NSString *)newUsername password:(NSString *)newPassword
{
NSLog(#"uset sername %# and password %#",newUsername,newPassword);
...
}
I debug in all function but I saw this function is running after loggedin. But this is printing null in password value although username is printing well. Actually I I have to trace all tweet value of user. I went through MGTwitterEngine. There is a block of code but it is necessary to write username and password.
Here is the code
MGTwitterEngine *twitterEngine = [[MGTwitterEngine alloc] initWithDelegate:self];
[twitterEngine setUsername:#"username" password:#"password"];
// Get updates from people the authenticated user follows.
NSString *connectionID = [twitterEngine getFollowedTimelineFor:nil since:nil startingAtPage:0];
Please help me how to keep password ?

Read the developer documentation, it provides all the info you need for something as easy as this. Back to the question, there're a couple of ways how you can save this data.
NSUserDefaults: You can save the username and password using this class like this:
[[NSUserDefaults sharedUserDefaults] setObject:username forKey:#"username"];
[[NSUserDefaults sharedUserDefaults] setObject:username forKey:#"password"];
[[NSUserDefaults sharedUserDefaults] synchronize];
Once you need this data again, call it:
NSString*username = [[NSUserDefaults standardUserDefaults] objectForKey:#"username"];
NSString*password = [[NSUserDefaults standardUserDefaults] objectForKey:#"password"];
OR:
NSDictionary: If you don't want to rely on NSUserDefaults, you can save the login data in a NSDictionary and save it to your sandbox. This works like this:
NSMutableDictionary*loginDictionary = [[NSMutableDictionary alloc] init];
[loginDictionary setObject:username forKey:#"username"];
[loginDictionary setObject:password forKey:#"password"];
[loginDictionary writeToFile://Your Path Here atomically:NO];
[loginDictionary release];
Then, once you need the data again, read from file:
NSMutableDictionary*loginDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile://Your Path];
NSString*username = [loginDictionary objectForKey:#"username"];
NSString*password = [loginDictionary objectForKey:#"password"];
[loginDictionary release];
Hope it helps!
