iPhone login screen number pad

I am writing an app and I want to show the login screen ju开发者_运维百科st like in iPhone where you have to enter 4 digit code to login. What's the best way to do this? Is there a UIView that comes with the SDK or will i have to design my own keyboard Thanks

CocoaControls is an excellent site to browse Cocoa & Cocoa Touch custom UI components:

http://cocoacontrols.com/

You can use PINView: http://cocoacontrols.com/platforms/ios/controls/pinview

Or KVPasscodeViewController: http://cocoacontrols.com/platforms/ios/controls/kvpasscodeviewcontroller

Or JSLockScreen: http://cocoacontrols.com/platforms/ios/controls/jslockscreen

Previously answered at steps / idea for a Iphone passcode like custom interface for Application: this option from that question looks promising (see https://github.com/vikingosegundo/KeyPad).

You can use this latest source code to do so. URL is https://github.com/abury/ABPadLockScreen

Hopes this will help you.
