Radio Button for iOS
Pretty simple class that extends standard UIButton functionality. Default and selected states can be configured for every button.
Super easy to use
It does not need any central manager. Just link the buttons right in Interface Builder:
Alternatively group the buttons using single line of code:
radio1.groupButtons = @[radio1, radio2, radio3];
Select any button, and all other button in the same group become deselected automatically:
radio2.selected = YES; // radio1 and radio3 become deselected
Any button from the group knows which one is selected:
RadioButton* r1 = radio1.selectedButton; RadioButton* r2 = radio2.selectedButton; RadioButton* r3 = radio3.selectedButton; NSAssert (r1==r2 && r2==r3, @"Must be equal");
And a helpful method to select button by tag:
RadioButton is available under the MIT license - fork, modify and use however you want.
