Here are my objective-c classes:
AppDelegate
SomeScript
How might I call the function loggedIn on the SomeScript class from the app-delegate or any other class?
(I'll assume loggedIn
is an instance method taking no parameters.) First, several terminology issues:
So, our new plan is to first instantiate SomeScript, then send a message to the instance.
SomeScript* myScript = [[SomeScript alloc] init]; //First, we create an instance of SomeScript
[myScript loggedIn]; //Next, we send the loggedIn message to our new instance
This is good. However! I bet you want your script to stick around for later use. Thus, we should really make it an instance variable of your app delegate. So, instead, in AppDelegate.h, add this inside the braces:
SomeScript* myScript;
Now our variable will stick around, and our first line from before becomes simply:
myScript = [[SomeScript alloc] init];
Last complication: we don't want to create a new script every time we call loggedIn
(I assume)! So, you should place the instantiation somewhere it will only be run once (for example, application:DidFinishLaunchingWithOptions:
). Ta-da!
