如何打开OAuth弹出窗口（窗口层次结构）

Question

The implementation of this part should be pretty straightforward (but it isn't)

I implemented OAuthIODelegate into LoginViewController but the problem is when I run this code:

OAuthIOModal *oauthioModal = [[OAuthIOModal alloc] initWithKey:@"the_key" delegate:self];
[oauthioModal showWithProvider:@"facebook"];

Then I get this:

Warning: Attempt to present OAuthIOModal: 0x14ecc8e0 on MenuViewController: 0x14eb8d80 whose view is not in the window hierarchy!

The problem with this is that I'm not even calling this on MenuViewController.

For testing purposes I'm calling LoginViewController from MenuViewController and then from login controller when I press a button I run the code above.

I've tried to find a solution but nothing this specific popped up.

Help would be appreciated.

tnx

Answer 1

MenuViewController is set as your root view controller, but it isn't loaded (yet). I presume you're moving between views at this point.

Try putting your code in MenuViewController.m : viewDidLoad . You might need something to shift other business logic around this, but essentially you can't show a popup until the view has loaded.

- (void)viewDidLoad {
    [super viewDidLoad];
    OAuthIOModal *oauthioModal = [[OAuthIOModal alloc] initWithKey:@"the_key" delegate:self];
    [oauthioModal showWithProvider:@"facebook"];
}
