PSTDelegateProxy 0.0.1

Maintained by Unclaimed.

You want to add pod 'PSTDelegateProxy', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'PSTDelegateProxy', '~> 0.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try PSTDelegateProxy

A simple proxy that forwards optional methods to delegates - less boilerplate in your code!

When calling optional delegates, the regular pattern is to check using respondsToSelector:, then actually call the method. This is straightforward and easy to understand:

    id<PSPDFResizableViewDelegate> delegate = self.delegate;
    if ([delegate respondsToSelector:@selector(resizableViewDidBeginEditing:)]) {
        [delegate resizableViewDidBeginEditing:self];
    }

What we really want is something like this:

    [self.delegateProxy resizableViewDidBeginEditing:self];
