UITextView 隐藏键盘
本文原本的排版效果：这里
在 viewDidLoad 方法中：
// 在输入框加一个 Done 按钮退出键盘
UIToolbar *topView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 30)];
// 这里缺少 Button1，Button2 的话，doneButton 按钮会被放到 toolbar 的左边
UIBarButtonItem *Button1 = [[UIBarButtonItem alloc]initWithTitle:@"" style:UIBarButtonItemStyleBordered target:self action:nil];
UIBarButtonItem *Button2 = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(dismissKeyBoard)];
[topView setItems:@[Button1,Button2,doneButton]];
[self.textView setInputAccessoryView:topView];
dismissKeyBoard 方法：
-(void)dismissKeyBoard{
[self.textView resignFirstResponder];
}
