Question

如何在另一个presentModalView中显示presentModalView？

我想这样称呼：

[button addTarget:self action:@selector(settingsTapped) forControlEvents:UIControlEventTouchUpInside];

在这里

UINavigationController *_nc = [[[UINavigationController alloc] initWithRootViewController:scannerVC] autorelease]; //Put our SKScannerViewController into a UINavigationController. (So it looks nice).
        [scannerVC release];

[self presentModalViewController:_nc animated:YES]; //Slide it up onto the screen.

然后

//another screen pop up in _nc
qrcode_info *otherVC = [[qrcode_info alloc] initWithNibName:@"qrcode_info" bundle:Nil  ];

//  [self presentModalViewController: otherVC animated:YES];

只需在视频控制器中以模态方式显示-presentModalViewController:animated:。
