Self login in Salesforce API in iPhone? - iphone

Question

I am using Salesforce api and i want to login automatically(hard code user name and password). i am using REST API and here is the login code which shows login form:
- (void)login {
SFOAuthCredentials *credentials = [[[SFOAuthCredentials alloc] initWithIdentifier:remoteAccessConsumerKey] autorelease];
credentials.protocol = #"https";
credentials.domain = OAuthLoginDomain;
credentials.redirectUri = OAuthRedirectURI;
self.coordinator = [[[SFOAuthCoordinator alloc] initWithCredentials:credentials] autorelease];
self.coordinator.delegate = self;
NSLog(#"%#",self.coordinator);
// remove this line if we want to cache the key, and use refresh flow
//effectively, we are saying, purge the old login and re-authenticate each time
[self.coordinator revokeAuthentication];
//now let's authenticate
[self.coordinator authenticate];
}
What i want, to automatically login (not ask username or password) so where i insert user name and password?

Answer 1

The Salesforce toolkit for iOS page shows an example of it using ZKSForce which returns a token that can be used by the REST API calls, see the document here
The REST API typically uses an OAuth token which saves the user from having to enter their username and password into a third party system such as yours. They enter the login once and the system refreshes the token to stay logged in (this is an oversimplified explanation). Either use OAuth which is the correct way with mobile and the REST API or use the session ID from an old style SOAP login request.

A quick Google and I found this - https://github.com/superfell/zkSforce
Haven't tried it yet though!

Include zkforce in your project
Add These files in your project
#import "ZKSforce.h"
#import "FDCServerSwitchboard.h"
#import "ZKLoginResult.h"
Add this code in .m
NSString *username =
NSString *password =
NSString *token = #"amnwcg24Uu5IenCvAJM5HgRq";
NSString *passwordToken = [NSString stringWithFormat:#"%#%#", password, token];
[[FDCServerSwitchboard switchboard] loginWithUsername:username password:passwordToken target:self selector:#selector(loginResult:error:)];
See result
- (void)loginResult:(ZKLoginResult *)result error:(NSError *)error
{
if (result && !error)
{
NSLog(#"Hey, we logged in!");
//[self fetchAccounts];
}
else if (error)
{
NSLog(#"An error occurred while trying to login.");
}
}
