问题描述

我的iPhone应用程序出现问题.

有2个UIViewController.

第一个UIViewController与UITextField并向上键盘.一旦我用presentViewController打开其他UIViewController，我的键盘就会自动按下.

有什么办法可以强制打开键盘?我不想用键盘解雇.

So is there any way to I can forcefully open keyboard? I do not want to keyboard dismiss.

推荐答案

您可以在新的视图控制器中尽早打开它，如下所示(在第二个视图控制器中):

You can open it in the new view controller at the earliest possible point like this (In the second view controller):

- (void)viewWillAppear:(BOOL)animated {
    [_textField becomeFirstResponder];
}

您将看到键盘返回，然后立即重新出现.

You will see the keyboard return and then re-appear immediately..

如果您也想解决这个问题，我想到的唯一方法就是在presentViewController中禁用动画(在第一个视图控制器中):

If you want to get around that too the only way I can think of is to disable animations in presentViewController (In the first view controller):

[self presentViewController:secondViewController animated:NO completion:nil];
