Resize UIView to fit its content

Question

The problem is, that I do have a view containing 3 parts.

The first part is a simple header - same height always! The second part is a simple description line - same height always!

Now the problem is the third part. It's a viewContainer for dynamically calculated subviews (each of them having a custom controller). The height of the content is dynamic caused by some text information downloaded from a backend. So some times I would need to scroll to be able to read the whole text, sometimes not.

Currently I am doing it this way:

• Calculate the size of the UILabel for a specific text.
• Then resize the parent view so fit the UILabel (if smaller).
• Then resize the scrollView of my 3-Part-ViewController-View to fit its subviews.

The detail viewController with the dynamic content:

    self.labelDescription.text = self.customData.descriptionText;
    [self.labelDescription sizeToFit];
    if(self.view.frame.size.height < (self.labelDescription.frame.size.height + self.labelDescription.frame.origin.y)) {
    CGRect newSize = CGRectMake(0,
                                0,
                                self.view.frame.size.width,
                                self.labelDescription.frame.size.height +
                                self.labelDescription.frame.origin.y);
    self.view.frame = newSize;
    }

The resizing of the scroll view after adding and resizing my detail view:

[self addChildViewController:controllerCustomData];
[self.scrollView addSubview:controllerCustomData.view];    
CGRect newRect = CGRectMake(0,
                            self.viewElementDetailContentContainer.frame.origin.y,
                            controllerCustomData.view.frame.size.width,
                            controllerCustomData.view.frame.size.height);
controllerCustomData.view.frame = newRect;
self.scrollView.contentSize = CGSizeMake(self.scrollView.contentSize.width, newRect.origin.y + newRect.size.height);

So my question is, are there easier ways to do this?

Answer 1

You could create a method that does everything you need. You'll need to write the method (maybe methodS) once and use it passing the necessary arguments.
