iOS iPad开发之Modal

1. 最普通的Modal

　　QKSecondViewController *second = [[QKSecondViewController alloc]init];

　　[self presentViewController:second animated:YES completion:nil];

　　前者决定以怎样的动画出来, 后者决定动画结束后展示的面积

UIModalTransitionStyleCoverVertical = 0, 垂直爬上来

UIModalTransitionStyleFlipHorizontal, 水平翻转

UIModalTransitionStyleCrossDissolve, 淡入淡出

UIModalTransitionStylePartialCurl, 翻书效果

second.modalTransitionStyle = UIModalTransitionStylePartialCurl;

　 PS:翻书效果时,动画执行完后,iOS7/8的区别,左为iOS7,右为iOS8

UIModalPresentationFullScreen = 0, 全屏

UIModalPresentationPageSheet, 横竖屏宽度都是768,高度为屏幕高度

UIModalPresentationFormSheet, iPad开发中最常用,中间一小块显示

second.modalPresentationStyle = UIModalPresentationPageSheet;
