我正在使用自定义标头创建TableView。在自定义标题中,我有1个ImageView,2个UILabel和1个UIButton。当我在UIButton上设置TouchUpInSide事件时,它不会触发。
我在SO和google上看到很多帖子,但没有任何东西可以帮助我。
这里我尝试过:
1)。 Swift - Custom TableView Not Executing Click on UIButton
2)。 UIButton in UITableView tableHeaderView not responding to touches
3)。 UIButton in a UITableView header ignores most touches
这是我的自定义标题的代码。
代码:
public override void ViewDidLoad()
{
base.ViewDidLoad();
TableView.Frame = new RectangleF((float)TableView.Frame.Left, 130, (float)TableView.Frame.Width, (float)(View.Frame.Size.Height - 130));
headerView = new UIView();
headerView.Frame = new CoreGraphics.CGRect(0, 0, TableView.Frame.Width, 140);
UIImageView backgroundImage = new UIImageView();
backgroundImage.Image = UIImage.FromFile("drawerbg");
backgroundImage.Frame = new CoreGraphics.CGRect(0, 0, TableView.Frame.Width, 140);
headerView.AddSubview(backgroundImage);
profileImage = new UIImageView();
profileImage.Frame = new CoreGraphics.CGRect(10, 10, 70, 70);
profileImage.Layer.CornerRadius = 35;
profileImage.ClipsToBounds = true;
profileImage.Image = UIImage.FromBundle("default_user");
backgroundImage.AddSubview(profileImage);
userName = new UILabel();
userName.Frame = new CoreGraphics.CGRect(10, 90, TableView.Frame.Width - 20, 20);
userName.Font = GargiFontAndSize.B14();
userName.TextColor = UIColor.White;
backgroundImage.AddSubview(userName);
userOrganization = new UILabel();
userOrganization.Frame = new CoreGraphics.CGRect(10, 110, TableView.Frame.Width - 50, 20);
userOrganization.Font = GargiFontAndSize.B14();
userOrganization.TextColor = UIColor.White;
userOrganization.Text = "Organizaton";
backgroundImage.AddSubview(userOrganization);
organizationArrowButton = new UIButton();
organizationArrowButton.Frame = new CoreGraphics.CGRect(260, 110, 20, 20);
organizationArrowButton.SetImage(UIImage.FromBundle("sort_down"), UIControlState.Normal);
organizationArrowButton.UserInteractionEnabled = true;
organizationArrowButton.ClipsToBounds = false;
backgroundImage.AddSubview(organizationArrowButton);
organizationArrowButton.BringSubviewToFront(headerView);
TableView.SectionHeaderHeight = 0;
TableView.SectionFooterHeight = 0;
var gradient = new CAGradientLayer();
gradient.Frame = headerView.Frame;
gradient.Colors = new CoreGraphics.CGColor[] { GargiColor.PrimaryColor().CGColor, GargiColor.SecondaryColor().CGColor };
headerView.Layer.InsertSublayer(gradient, 0);
TableView.TableHeaderView = headerView;
}
我的viewController还有一个扩展DialogViewController。
任何帮助都会得到赞赏..

默认情况下,UIImageView的userInteraction被禁用,您正在向图像视图添加按钮,为UIImageView将userInteractionEnabled设置为true。
