添加按钮隐藏键盘 [英] Add a button to hide keyboard

问题描述

在UITextView上隐藏键盘，有以下方法：

On a UITextView to hide the keyboard, there is the method:

...
    textfield.returnKeyType = UIReturnKeyDone;
    textfield.delegate = self;
....

-(BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;

}

但如果我想将按钮完成

but if I want to leave the button "done" to the "return" and add a button to hide the keyboard, how do I?

推荐答案

您可以为工具栏分配一个按钮将文本字段的 inputAccessoryView 解除键盘。一个快速示例是

You can assign a toolbar with a button that dismisses the keyboard as the text field's inputAccessoryView. A quick example would be,

UIBarButtonItem *barButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:textField action:@selector(resignFirstResponder)] autorelease];
UIToolbar *toolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)] autorelease];
toolbar.items = [NSArray arrayWithObject:barButton];

textField.inputAccessoryView = toolbar;
