Using radio buttons in iPhone app

How do I a use radio button in an iPhone app? Sho开发者_JAVA百科uld I load any image instead of button image?

A fairly standard replacement for radio buttons on iOS is a "picker". An alternative, if you have a large number of potential choices, is to use a static list under a button, and allow only one of the items to be selected and checkmarked.

You can use a custom button & change its image on button click

Take a look at the UISegmentedControl. It functions basically as a radio button for up to ~4 options. There's no maximum limit AFAIK, but any more than 4 is somewhat difficult visually.

Try DLRadioButton, the best Radio Button control for iOS. It is highly customizable, you can also use you own image as selection indicator. It is available through Cocoapods pod 'DLRadioButton', '~> 1.4' and at GitHub.
