UITextField的InputAccessoryView

Question

我需要把一个里面有UITextField的toolBar贴在键盘上。

如果我将整个toolBar (我认为是textField的超级视图)设置为它的textField的inputAccessoryView，会怎么样呢？

我的意思是这样的：

textField.inputAccessoryView = toolBar；// textField在toolBar内部

我一直在尝试这个，但我还没有让它工作。

有人能帮上忙吗？

或者有没有其他方法来实现我想要的？

Answer 1

您什么时候设置该属性？您可以在加载视图后设置它。

尝试将其设置为

- (void) viewDidLoad

Answer 2

   - (void)viewDidLoad
      {
        [self createAccessoryView];

        [textField setDelegate:self];
        [textField setKeyboardType:UIKeyboardTypeDefault];
        [textField setInputAccessoryView:fieldAccessoryView];


      }


- (void)createAccessoryView
        {

            CGRect frame = CGRectMake(0.0, self.view.bounds.size.height, self.view.bounds.size.width, 44.0);
            fieldAccessoryView = [[UIToolbar alloc] initWithFrame:frame];
            fieldAccessoryView.barStyle = UIBarStyleBlackOpaque;
            fieldAccessoryView.tag = 200;

            [fieldAccessoryView setBarStyle:UIBarStyleBlack];

            UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
            UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone  target:self action:@selector(done:)];

            UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:NSLocalizedString(@"Previous", @""), NSLocalizedString(@"Next", @""), nil]];
            [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
            segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
            [segmentedControl setMomentary:YES];
            UIBarButtonItem *segmentButton = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];

            [fieldAccessoryView setItems:[NSArray arrayWithObjects:segmentButton, spaceButton, doneButton, nil] animated:NO];
            [segmentButton release];
            [spaceButton release];
            [doneButton release];
            [segmentedControl release];

        }
