Viewing Method Parameter Information

Parameter hints for methods

Place the caret anywhere within the call of the desired method or function and choose View | Parameter Info on the main menu or press ⌘P.

Configuring the behavior of parameter hints

Open the Code Completion page (AppCode | Preferences | Editor | General | Code Completion) and configure the following options in the Parameter info section:

1. To have a complete method or function signature shown rather than a list of required types, select the Show full signatures checkbox.
   
2. To have the list of parameter types for the called method or function shown automatically after a certain delay, select the Auto pop-up (in ms) checkbox and specify the time period in milliseconds.
