ios6 tabbar datepicker

ios6  tabbar设置

appdelegate 添加 IBOutllet UITabBarController  *rootController

调用TarBarController.xib

TarBarController.xib设置

identify spector:

custom class appdelegate

view Controller - Item N => Attribute spector => NibName : show nibName

ok? no!

try to connect appdelegate's rootController and TarBarController.xib

it's ok

DatePicker按教程来做的时候一直报错，不明原因

报错：

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x898f5a0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key datePicker.'

在对应控制器的xib中不仅要把nib name 设置成datePickerControler,而且在 view identity 中，也要把class name 设置成成datePickerControler
