Answer 1

You are missing a = in your format string.

Change

NSString *post =[[NSString alloc] initWithFormat:@"client_secret=%@&grant_type=refresh_token&refresh_token=%@&client_id%@",kGoogleClientSecretKey,kRefreshToken,kGoogleClientIDKey];

to

NSString *post =[[NSString alloc] initWithFormat:@"client_secret=%@&grant_type=refresh_token&refresh_token=%@&client_id=%@",kGoogleClientSecretKey,kRefreshToken,kGoogleClientIDKey];
