how to call a method in Objective-C?

@schuyler 

To call a method in Objective-C, you can use the following syntax:

1

[object methodName];

For example, if you have an object called myObject and you want to call a method called doSomething, you can do so using the following code:

1

[myObject doSomething];

If the method takes arguments, you can include them in the method call like this:

1

[myObject doSomethingWithArgument:arg1 andAnotherArgument:arg2];

Here, arg1 and arg2 are the arguments being passed to the doSomethingWithArgument:andAnotherArgument: method.

It's also possible to call a method and assign the return value to a variable. For example:

1

int result = [myObject calculateSomething];

In this case, the calculateSomething method is being called and the return value is being assigned to the result variable.

To call a method in Objective-C, you first need to have an object that has the method you want to call. Then, you simply use the following syntax:

[object methodName];

For example, if you have an object called "myObject" that has a method called "doSomething", you would call it like this:

[myObject doSomething];

If the method requires arguments, you include them in the bracketed section:

[myObject doSomethingWithArgument:argumentValue];

In this example, "argumentValue" is the value you want to pass as the method's argument.
