1. 首先在http://open.t.sina.com.cn/中申请成为开发者，再创建不同的应用，获得相应的AppKey （在下面链接中的source即为appkey）

 

2. 登录认证：

NSString *authString= [NSString stringWithFormat:@"%@:%@",sinaIDField.text,sinaPasswordField.text];

NSData *authData= [authString dataUsingEncoding:NSUTF8StringEncoding];

NSString *authValue= [NSString stringWithFormat:@"Basic%@",[authData base64EncodingWithLineLength:80]];

 

NSURL *url= [NSURL URLWithString:@"http://api.t.sina.com.cn/account/verify_credentials.xml?source=3930264715"];

NSMutableURLRequest *request= [[NSMutableURLRequest alloc] initWithURL:url];

[request setHTTPMethod:@"GET"];

[request setValue:authValue forHTTPHeaderField:@"Authorization"];

 

NSURLResponse *response;

NSError *error;

 

[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

 

[request release];

 

NSHTTPURLResponse *httpResponse= (NSHTTPURLResponse *)response;

 

int statusCode= [httpResponse statusCode];

 

NSLog(@"statuscode = %d",statusCode);

 

if (statusCode!= 200){

alertTitle = @"帐号或密码错误";

alertMassage = @"请您输入正确的帐号和密码！";

}else {

alertTitle = @"";

alertMassage = @"登录成功！";

}

}

UIAlertView *alert= [[UIAlertView alloc] initWithTitle:alertTitle

message:alertMassage

delegate:nil cancelButtonTitle:@"确定"

otherButtonTitles:nil];

[alert show];

[alert release];
