iOS 模态视图转场的动画效果

    ModalViewController * modalView = [[ModalViewController alloc]init];
    modalView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    
   // [self presentModalViewController:modalView animated:YES];  ios 6 弃用了该方法
    [self presentViewController:modalView animated:YES completion:nil];

typedef NS_ENUM(NSInteger, UIModalTransitionStyle) {

    UIModalTransitionStyleCoverVertical = 0,//默认垂直向上

    UIModalTransitionStyleFlipHorizontal, 翻转效果

    UIModalTransitionStyleCrossDissolve,淡入淡出

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_3_2

    UIModalTransitionStylePartialCurl,翻页效果

#endif

};
