ios 異常錯誤積累

1.沒找到對應的方法

'NSInvalidArgumentException',reason:'-[TestClass initEvent]:unrecognized selector send to instance 0x10011b330'

2.找不到AViewController.xib,可能是xib的名字寫錯了

2012-08-18 22:52:33.922 HelloiPhone[667:c07] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/xue/Library/Application Support/iPhone Simulator/6.0/Applications/063D5459-6BE3-43A6-8EB3-F03A43C42917/HelloiPhone.app> (loaded)' with name 'AViewController''

3.

reason: ‘Could not instantiate class named NSLayoutConstraint

解決辦法：需要關閉storyboard或xib介面檔案的Use Auto Layout 選項，這是因為Auto Layout特性是iOS 6 新增加的，在之前的 5.0/5.1 Simulator模擬器中不支援。
