 IOS6.0之后的模态视图呈现方法加了块语法。这里先判断系统版本以执行不同的方法。

模态视图消失时执行方法的顺序 

-[ModelViewController viewWillAppear:]
-[ModelViewController viewDidAppear:]
2013-05-27 22:58:11.434 test1[17382:11303] call back
-[ModelViewController viewWillDisappear:]
-[ModelViewController viewDidDisappear:]
-[ModelViewController dealloc]
2013-05-27 22:58:15.908 test1[17382:11303] dismiss call back

 

 //自下向上推出（默认） UIModalTransitionStyleCoverVertical

    //淡入淡出效果 UIModalTransitionStyleCrossDissolve

    //左右翻转 UIModalTransitionStyleFlipHorizontal

    //翻书效果 UIModalTransitionStylePartialCurl 

//    mvc.modalTransitionStyle = UIModalTransitionStylePartialCurl;
