模態視圖 push pop

標籤：模態視圖 push pop

導航控制器用來管理一組具有層級關係的視圖控制器,進入下一個介面的方式是push,返回是pop.   (層級關係:後一個介面顯示的內容依賴於前一個介面)

當沒有層級關係的視圖控制器之間切換時(比如:前一個介面顯示的內容依賴於後一個介面).要使用模態視圖,進入下一個介面的方式是present,返回是dismiss.

模態視圖:

- (IBAction)pressButton:(UIButton *)btn

{

    FirstDetailViewController *firstDetailVC = [[FirstDetailViewController alloc] init];

    firstDetailVC.modalTransitionStyle =UIModalTransitionStyleFlipHorizontal;

    [self presentViewController:firstDetailVC animated:YES completion:^{

        NSLog(@"Tsummer");

    }];

}

- (IBAction)pressDetailButton:(UIButton *)sender

{

    [self dismissViewControllerAnimated:YES completion:^{

        NSLog(@"Tsummer");

    }];

}

系統提供的頁面切換的效果:

typedef NS_ENUM(NSInteger, UIModalTransitionStyle) {

    UIModalTransitionStyleCoverVertical = 0,  //從底部劃入

    UIModalTransitionStyleFlipHorizontal,  //水平翻轉

    UIModalTransitionStyleCrossDissolve,  //交叉溶解

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_3_2

    UIModalTransitionStylePartialCurl,  //翻頁效果

#endif

};

push推出

- (IBAction)pressButton:(UIButton *)btn

{

    FirstDetailViewController *firstDetailVC = [[FirstDetailViewController alloc] init];

    [self.navigationController pushViewController:firstDetailVC animated:YES];

}

- (IBAction)pressDetailButton:(UIButton *)sender

{

    [self.navigationController popViewControllerAnimated:YES];//pop上一介面

   // [self.navigationController popToRootViewControllerAnimated:YES];//pop主視圖控制器介面

   // [self.navigationController popToViewController:(UIViewController *) animated:YES];//當存在多個頁面時,自訂pop到哪一個頁面

}
