导航标题未显示在 ResearchKit 中

Navigation title not showing up in ResearchKit

如何在 Research Kit 中显示 TaskViewController 的标题?我一直在尝试以下操作,但它似乎没有出现,尽管可以通过这种方式设置其他属性。

    let taskViewController = ORKTaskViewController(task: ConsentTask, taskRunUUID: nil)
    taskViewController.navigationBar.topItem!.title = "TITLE"
    taskViewController.restorationIdentifier = "1"
    taskViewController.delegate = self
    presentViewController(taskViewController, animated: true, completion: nil)

我也试过了taskViewController.title = "TITLE".

您需要执行两个步骤:

1) 关闭进度标题:

taskViewController.showsProgressInNavigationBar = NO;

2) 为 ORKTaskViewController 实施并设置 delegate:

- (void)taskViewController:(ORKTaskViewController *)taskViewController stepViewControllerWillAppear:(ORKStepViewController *)stepViewController {
    stepViewController.title = @"Your title";
}
