将完成按钮添加到键盘顶部

问题描述：

我正在制作一个具有UITextView的通用应用。
当应用程序在iPad上运行时，右下角有一个按钮，可以让我关闭键盘。
iPhone版没有这样的按钮。
我在一些iPhone应用程序上看到键盘顶部有一个带有完成选项的栏。
是否有一种简单的方法可以将iPad风格的键盘按钮添加到iPhone应用程序中。
如果没有，将完成样式栏添加到键盘顶部的最佳方法是什么？
提前致谢。

I am making a universal app that has a UITextView. When the app run on the iPad there is a button on the lower right which enables me to dismiss the keyboard. The iPhone version does not have such a button. I have seen on some iPhone apps a bar on top of the keyboard that has a done option. Is there an easy way to add an iPad style dismiss keyboard button to the iPhone app as well. If not, what is the best way to add a done style bar to the top of the keyboard? Thanks in advance.

请尝试此代码

 //set up a placeholder variable for the textfield user typing
 UITextView *currentTextView;

-(void)addDoneToolBarToKeyboard:(UITextView *)textView
{
    UIToolbar* doneToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
    doneToolbar.barStyle = UIBarStyleBlackTranslucent;
    doneToolbar.items = [NSArray arrayWithObjects:
                       [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                       [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneButtonClickedDismissKeyboard)],
                       nil];
    [doneToolbar sizeToFit];
    textView.inputAccessoryView = doneToolbar;
}

 //remember to set your text view delegate
 //but if you only have 1 text view in your view controller
 //you can simply change currentTextField to the name of your text view
 //and ignore this textViewDidBeginEditing delegate method
 - (void)textViewDidBeginEditing:(UITextView *)textView
 {
     currentTextView = textView;
 }

-(void)doneButtonClickedDismissKeyboard
{
     [currentTextView resignFirstResponder];
}

并在您的视图中添加此功能

and add this in your view did load

 [self addDoneToolBarToKeyboard:self.textView];

希望有所帮助
