inputaccessoryview not showing（StoryBoard）

Question

我一直試圖在我的鍵盤上方加入UIView/Toolbar，但沒有運氣。當我添加了一個工具欄時，它被加擾，因此我需要將它放入UIView，但UIView不希望出現在鍵盤上方。下面的代碼：

我的頭：

@property (nonatomic, Strong) IBOutlet UITextView *textView; 
@property (nonatomic, strong) IBOutlet UIToolbar *TitleBar; 
@property (nonatomic, weak) IBOutlet UIView *AddView; 

的ViewDidLoad：

- (void)viewDidLoad 
{  
    // observe keyboard hide and show notifications to resize the text view appropriately 
    /*[[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(keyboardWillShow:) 
               name:UIKeyboardWillShowNotification 
               object:nil]; 
    */ 

    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) { 
     // iOS 7 
     [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)]; 
    } else { 
     // iOS 6 
     [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide]; 
    } 

    self.attributionTitle.delegate = self; 
    self.attribution.delegate = self; 
    textView.scrollEnabled = YES; 
    // quoteText.layer.borderColor = [UIColor blackColor].CGColor; 
    // quoteText.layer.borderWidth = 1.0f; 

    // textView.delegate = self; // code or in IB 

    [textView becomeFirstResponder]; 

    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
} 

的textViewDidBeginEditing：

-(void)textViewDidBeginEditing:(UITextView *)textView 
{ 
    self.textView.inputAccessoryView = self.AddView; 
} 

這裏是展示UIView連接：​​

Answer 1

我將textView.inputAccessoryView = AddView;添加到ViewDidLoad，然後從故事板中刪除視圖並重新制作它。最後，我將UIView添加到底部的黑色欄中。

Answer 2

在textViewDidBeginEditing中添加inputAccessoryView可能太晚了。輸入附件視圖應在此之前設置，例如，在viewDidLoad方法中。

嘗試類似：

-(void)viewDidLoad{ 
    [super viewDidLoad]; 

UIView 

    myTextField.inputAccessoryView = [self accessoryViewWithPreviousEnabled:NO nextEnabled:YES]; 

    // more stuff as required... 
} 

以及創建一個/下一個按鈕的方法（你需要的按鈕提供你自己的圖像，並實現了previousAccessoryViewButtonTapped:和previousAccessoryViewButtonTapped:方法）。需要兩個參數BOOL來指示是否應啓用上一個和/或下一個按鈕。

#pragma mark - Accessory view methods 

-(UIView *)accessoryViewWithPreviousEnabled:(BOOL)previousEnabled nextEnabled:(BOOL)nextEnabled{ 
    previousButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    previousButton.frame = CGRectMake(10, 2, 60, 30); 
    [previousButton setImage:[UIImage imageNamed:PREVIOUS_BUTTON] forState:UIControlStateNormal]; 
    previousButton.enabled = previousEnabled; 
    [previousButton addTarget:self action:@selector(previousAccessoryViewButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; 

    nextButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    nextButton.frame = CGRectMake(80, 2, 60, 30); 
    [nextButton setImage:[UIImage imageNamed:NEXT_BUTTON] forState:UIControlStateNormal]; 
    nextButton.enabled = nextEnabled; 
    [nextButton addTarget:self action:@selector(nextAccessoryViewButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; 

    UIView *transparentBlackView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1024, 34)]; 
    transparentBlackView.backgroundColor = [UIColor colorWithRed:0.f green:0.f blue:0.f alpha:0.6f]; 

    UIView *accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1024, 34)]; 
    [accessoryView addSubview:transparentBlackView]; 
    [accessoryView addSubview:previousButton]; 
    [accessoryView addSubview:nextButton]; 

    return accessoryView; 
} 

請注意，這種方法是針對橫向iPad的硬編碼。您需要爲iPhone更改它。

問題是您的self.AddView已經在您的界面中（因爲您將它放在故事板中）。它不能一次在兩個地方。
