I need to integrate Instagram login in my app. So I am redirecting to safari in my application to login in Instagram. but what i have to do is, if user have Insta app installed and he/she is already logged in there then the login screen should not come he can directly go to authentication approval.
my Login code is,
- (NSURLRequest *) loginRequest {
NSString * urlString = [NSString stringWithFormat:@"https://instagram.com/oauth/authorize/?client_id=%@&redirect_uri=%@&response_type=token", self.clientID, self.redirectURI];
NSURL * url = [NSURL URLWithString:urlString];
return [NSURLRequest requestWithURL:url];
}
I went through too many questions here but didn't got the answer. its not feasible or what , i am totally confused .
According to instagram official docs
There are two types of authentication available
Both of which uses a instagram end point to login the user in the web page.
There is no authentication available through their iOS/Android app
