您可以尝试以下代码：

  

注意：不要忘记make textView delegate。

UIToolbar *keyboardDoneButtonView = [[UIToolbar alloc] init];
[keyboardDoneButtonView sizeToFit];

UIBarButtonItem *flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                               style:UIBarButtonItemStylePlain target:self
                                                              action:@selector(doneClicked:)];

[keyboardDoneButtonView setItems:[NSArray arrayWithObjects:flexible, doneButton, nil]];


self.textView.inputAccessoryView = keyboardDoneButtonView;

IBAction功能：

- (IBAction)doneClicked:(id)sender
{
    NSLog(@"Done Clicked.");
    [self.view endEditing:YES];
}
