It was very strange when I saw this on debugging my application. 

int iTag = btnTemp.tag;    //btnTemp.tag = 1
NSString *strFriendID = [NSString stringWithFormat:@"%i",iTag];

gave me strFriendID as empty string.

int iTag = btnTemp.tag;       //btnTemp.tag = 1
NSString *strFriendID = [NSString stringWithFormat:@"%d",iTag];

gave me strFriendID as 1.

How can this happen?
