iOS how to properly exit a method?

[DennisBlah]

Just as my title already says.
My method looks a bit like this.
Sorry the code is really not related.

-(void)updateData {
  //Loading current data in plist
  //Doing some preperations and styling

  //If we don't have network connection or host is offline
    //Exit this function and init error viewcontroller

  //checking current data with online data and update
  //whilst we stay on this viewcontroller
}

How to exit the method after I'm initializing my next viewcontroller?

Use return

     return;

You can return... Or I'm pretty sure there's an implicit return at the end of a method that's declared as returning void.

Hmmm, ok I will try that

I thought only methods that are defined as a var can return.

Thanks guys!

Your Pseudocode suggested you wanted to return early. For those cases you can do a simple return when void is involved or return a value of the return type of the method or function.

Personally I try to avoid early returns as it can get messy to keep track of them in a large method. Knowing there is one return location at the end of the block of code means I only have to look there for the result.
