ios - 如何调整输入附件 View 的大小

Question

使用显示隐藏 iPhone 键盘和图像按钮(位于键盘顶部)。

    [kbdImage setFrame:CGRectMake(290, 0, 30, 30)];                                                             
    [accessoryView setFrame:CGRectMake(290, 0, 320, 30)];

    UITapGestureRecognizer *gestureRecogniser = [[UITapGestureRecognizer alloc]    initWithTarget:self action:@selector(hideKeyBoard:)];
     gestureRecogniser.numberOfTapsRequired = 1;

     [accessoryView addSubview:kbdImage];
     [accessoryView addGestureRecognizer:gestureRecogniser];


     for (UIView* v in searchBar.subviews) {
        if ([v isKindOfClass:[UITextField class]]) {
           ((UITextField*)v).inputAccessoryView = accessoryView ;
        }
     }

这适用于隐藏键盘。但输入 View 中的剩余区域也是可触摸的。如何避免这种情况。

Answer 1

发生这种情况是因为您向整个 AccessoryView 添加点击手势，因此整个 View 将响应点击手势，而不是仅向该图像按钮添加点击手势。

    kbdImage.userInteractionEnabled = YES;
    [kbdImage addGestureRecognizer:gestureRecogniser];
