Radio button in iPhone app

Question

I have to add radio buttons in my iPhone application. For that I have got radio button image which is of round in shape. Can I add that image as a subview? and Can I add touchupinside event to UIImage?

Answer 1

iPhone apps do not have radio buttons. The "iPhone-like" way to do this is either by using a picker view or by having several rows in a grouped table view with a check accessory on the chosen row.

If for some reason you really, really feel the need to have radio buttons, use a UIButton with a button type of custom. Set the empty circle as the image for the "normal" control state and the filled circle as the image for the "selected" state.

Answer 2

Try UISegmentedControl. It behaves similarly to radio buttons -- presents an array of choices and lets the user pick 1.

Answer 3

IBOutlet UIButton *checkboxButtonMale; 

IBOutlet UIButton    *checkboxButtonFmale;

  checkboxButtonFmale.tag = 3;
  checkboxButtonMale.tag = 2; 

(IBAction)checkboxGenderChecked:(id)sender{ 


    UIButton *selectedButton = (UIButton *)sender;
    UIButton    *toggledButton; 

    if (selectedButton.tag == 2 ) { 
        toggledButton =    checkboxButtonFmale;
    } 
    else {      
        toggledButton = checkboxButtonMale; 
    }   [toggledButton    setSelected:NO]; 
    [sender setSelected:YES];
       }
