Issit possible to load a UIVIewcontroller from uiview of another UIViewController

I have:

• an UIViewController A
• UIView B: I added subview which is a UIView to the UIViewController A
• an UIViewController C

What I did is:

in UIViewController A's viewDidLoad's method, I call this:

UIView *subviewB = [[Subview alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
[subviewB subviewBMethod]; // 
[self.view addSubview:subviewB];

SubviewBMethod code is to create an view, inside this view have a button. Once this button is clicked, it will change to UIViewController C.

I tried this:

[self presentModalViewController:self.UIViewControllerC animated:YES];

And I got this error message:

warning: incompatible Objective-C types 'struct UIViewControllerC *', expected 'struct UIViewController *' when passing argument 1 of 'presentModalViewController:animated:' from distinct Obj开发者_如何转开发ective-C type

When I run the app, it terminates immediately when I click the button, I opened the console bug, there is no any error message. My method must be wrong, thus my question is:

Is it possible to load a UIVIewcontroller from UIView of another UIViewController? If:

• Yes: How to do it?
• No: What should I do?

It looks like you have a declaration like this:

 UIViewControllerC *UIViewControllerC;
                 ^ 

When you want:

 UIViewController *UIViewControllerC;

I've recently done the same thing. - I have a viewControllerA that has a seeMoreView (a custom view) on it. When the user clicks "see more", viewControllerB is presented.

I solved it like this:

1. I subclassed seeMoreView.

2. I declared a delegate in the seeMoreView - syntax in this answer: Delegates Vs. Notifications in iPhoneOS

3. In viewControllerA I set the delegate of the seeMoreView as self when creating the view.

4. In viewControllerA I implement the delegate method, which presents viewControllerB.

(I don't think it's good practice in the MVC paradigm to call a view controller from a view.)

Can you try this?

[self presentModalViewController:(UIViewController *)self.UIViewControllerC animated:YES];
