Create a new control - IPhone development

1. Create control in view using Interface Builder's Liberary. As shown below:

2. Create outlet in view controller code.

• In the .h file, define the outlet for the control, example:

             IBOutlet UITextField *textField;   // add this to the @interface section
             @property (nonautomic,retain) UITextField *textField;   // add this outside of the @interface section

• In the .m code, example:

             @synthesize textField;    //add this into the .m code after the @implement line

3. Link the control in Interface Builder view, to the defined Outlet variable. Example:

4. Now the control, can be used in the code.

    Eg:

                 textField.text = @"hello world";     // to assign hello world to the text field

5. As the textField variable is defined as retain in the .h file, it need to be manually released in the dealloc

    method.

    Eg:

- (void) dealloc  {

   [textField release];   // add this line to manually relase the textField variable

   [super dealloc];

}
