iOS如何从UIViewController访问UIView属性

Question

Can someone Please walk me through the steps because I feel a little stuck and lost

Previous question : iOS - set UIButton target and action from its super class

Now I'm trying to get a more general idea - I'm very new to this

Help is very appreciated

If you are looking to access the UIView of an associated UIViewController from inside the view controller itself, you simply use self.view . To access the same UIView from outside of the UIViewController class you would use the instance name of the class plus the .view property. For example:

//SomeClass.m
- (void)accessVCView
{
   //With a Nib File:
   MyUIViewController *aVCObject = [[MyUIViewController alloc] initWithNibName:@"MyNib" bundle:nil];
   //Or with a Storyboard:
   MyUIViewController *aVCObject = [[UIStoryboard storyboardWithName:@"myStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"MyViewController"];

   UIView *myUIViewControllerView = aVCObject.view;
}
