Call "(id)sender" method in Xcode

Here is the method I wish to call:

- (void)myMethod:(id)sender {

How would I call it? I tried:

[self myMethod]

^error: Expected Expression before "]" token.

I know this is a simple question, but I am new to iPhone Development

Unless you wanted to send an unspecified-type object to your method you don't need the (id)sender portion:

- (void)myMethod {

}

You need to pass along a sender when you call it.

[self myMethod:something]

In other words, you need to have an argument to pass along when you call the method.

The method takes one parameter, so you have to give it one. If you have no sender you want to give, just pass nil:

[self myMethod:nil];

You could also overload the method as a convenience:

// declarations
- (void)myMethod;
- (void)myMethod:(id)sender;

// implementations
- (void)myMethod { [self myMethod:nil]; }
- (void)myMethod:(id)sender { /* do things */ }
