I downloaded "rem_iOS_SDK-10.6.2.10000-4" from sample SDK section. I found an demo which is only for iPad.
When i ran this demo, i prompted with screen where i have to send the details as POST request with url "https://10.137.96.87/csdk-sample/SDK/login" where 10.137.96.87 is server address. What i have to put in Username and Password field to continue within app.
Attached is the screenshot of first screen.
