我正在尝试在tapGesture
navigationBar
上添加titleView
,但是没有任何事件。请告诉我如何解决此问题。
let titleView = UIView()
titleView.frame = CGRect(x: 0, y: 0, width: 100, height: 60)
titleView.backgroundColor = UIColor.yellow
let profileImageView = UIImageView()
profileImageView.contentMode = .scaleAspectFill
profileImageView.layer.cornerRadius = 20
profileImageView.clipsToBounds = true
profileImageView.loadImageUsingCacheWithUrlString(urlString: user.image)
titleView.addSubview(profileImageView)
profileImageView.translatesAutoresizingMaskIntoConstraints = false
profileImageView.leftAnchor.constraint(equalTo: titleView.leftAnchor).isActive = true
profileImageView.centerYAnchor.constraint(equalTo: titleView.centerYAnchor).isActive = true
profileImageView.widthAnchor.constraint(equalToConstant: 40).isActive = true
profileImageView.heightAnchor.constraint(equalToConstant: 40).isActive = true
let nameLabel = UILabel()
nameLabel.text = user.name
nameLabel.font = UIFont(name: "HelveticaNeue-Medium", size: 17)
titleView.addSubview(nameLabel)
nameLabel.translatesAutoresizingMaskIntoConstraints = false
nameLabel.leftAnchor.constraint(equalTo: profileImageView.rightAnchor, constant: 8).isActive = true
nameLabel.centerYAnchor.constraint(equalTo: profileImageView.centerYAnchor).isActive = true
nameLabel.rightAnchor.constraint(equalTo: titleView.rightAnchor).isActive = true
nameLabel.heightAnchor.constraint(equalTo: profileImageView.heightAnchor).isActive = true
self.navigationItem.titleView = titleView
titleView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(showChatTableViewController)))
答案 0 :(得分:1)
确保将const psWithNonEmptyClass = document.querySelectorAll("p[class]:not([class=''])");
console.log(psWithNonEmptyClass.length);
设置为<p class="">Hello, world!</p>
<p class="5">Hello, world!</p>
<p class="9">Hello, world!</p>
<p class="">Hello, world!</p>
。默认情况下为true,但是如果您的情况无法使用,请尝试设置isUserInteractionEnabled
确保调试代码,并检查添加titleView后是否可以打印出true
?
true
