Experimental feature parity: automatic delegate

[zwaldowski]

A2BlockDelegate is wonderfully, incomparably awesome but the experimental branch needs to be in complete feature parity (not necessarily API compatible) with current BlocksKit. BlocksKit needs to "just work". The following snippet is currently valid in BlocksKit (though it's using the new API):

- (IBAction)sendMessage {
    MFMailComposeViewController *mailCompose = [MFMailComposeViewController new];
    [mailCompose setSubject:@"BlocksKit is great!"];
    mailCompose.completionBlock = ^(MFMailComposeViewController *vc, MFMailComposeResult result, NSError *err) {
        NSLog(@"Yay!");
    };
    [self presentModalViewController:mailCompose animated:YES];
}

This currently cannot be accomplished in the experimental branch without setting mailCompose.mailComposeDelegate, even if it is just to nil.

Even when we use [self registerDynamicDelegateNamed: @"mailComposeDelegate"]?

Yes. Horribly-done test project. It pulls in my local BlocksKit, but just replace that with your local BlocksKit.xcodeproj.

Solved with complete aplomb. ;-)

I am still experiencing this issue, even with the latest (1.0.4).

If I have a MFMailComposeViewController with a completionBlock but no mailComposeDelegate set, the mail compose view refuses to dismiss when I cancel it.

However, when I set the mailComposeDelegate to nil, it dismisses correctly.

Note that I am not calling dismissModalViewControllerAnimated in my completionBlock, because BlocksKit is supposed to handle that.

Cheers,
Nick

Same here, the following code works only, if I set the mailComposeDelegate to nil:

    MFMailComposeViewController *vc = [[MFMailComposeViewController alloc]init];
    vc.mailComposeDelegate = nil; // do not remove!
    [vc setSubject:@"Eversong"];
    [vc setMessageBody:@"my body text" isHTML:NO];
    [vc setCompletionBlock:^(MFMailComposeViewController *vc_, MFMailComposeResult result_, NSError *error_) {
        NSLog(@"completed");
    }];

    [self presentModalViewController:vc animated:YES];
