Answer 1

希望这有帮助:)

UIToolbar* keyboardToolbar = [[UIToolbar alloc] init];
[keyboardToolbar sizeToFit];
UIBarButtonItem *flexBarButton = [[UIBarButtonItem alloc]
                                  initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
                                  target:nil action:nil];
UIBarButtonItem *doneBarButton = [[UIBarButtonItem alloc]
                                  initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                  target:self action:@selector(yourTextViewDoneButtonPressed)];
keyboardToolbar.items = @[flexBarButton, doneBarButton];
self.yourTextView.inputAccessoryView = keyboardToolbar;

然后添加你的TextViewDoneButtonPressed方法

-(void)yourTextViewDoneButtonPressed
{
    [self.yourTextView resignFirstResponder];
}
