Must call a designated initializer of the superclass 'UITableViewCell'
提问by Sri Vathsav
let bubbleView : UIView = {
let view = UIView()
view.backgroundColor = blueColor
view.translatesAutoresizingMaskIntoConstraints = false
view.layer.cornerRadius = 16
view.layer.masksToBounds = true
return view
}()
let messageImageView : UIImageView = {
let imageView = UIImageView()
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.layer.cornerRadius = 16
imageView.layer.masksToBounds = true
imageView.contentMode = .scaleAspectFill
return imageView
}()
init(frame: CGRect) {
super.init(frame: frame)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
// getting error in like "super.init(frame: frame)" as Must call a designated initializer of the superclass 'UITableViewCell'please help me in sorting this problem thanks in advance...
// 像“super.init(frame: frame)”一样出现错误必须调用超类'UITableViewCell'的指定初始值设定项，请帮我解决这个问题，提前谢谢...

I guess the code that you provided is from UITableViewCelltype class. So in the initializer you should call designed initializer for this class. Not from UIView
我猜您提供的代码来自UITableViewCell类型类。因此，在初始化程序中，您应该为此类调用设计的初始化程序。不是来自UIView
The designated initializer for UITableViewCellclass is
UITableViewCell类的指定初始值设定项是
init(style: UITableViewCellStyle, reuseIdentifier: String?)
init(style: UITableViewCellStyle, reuseIdentifier: String?)
So in you class you should override this initializers:
因此，在您的课程中，您应该覆盖此初始化程序：
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
}

From the docs for init(style: UITableViewCellStyle, reuseIdentifier: String?):
从文档中init(style: UITableViewCellStyle, reuseIdentifier: String?)：
This method is the designated initializer for the class.
此方法是该类的指定初始值设定项。
The superinitializer you're calling is for UIView, not UITableViewCell.
super您正在调用的初始化程序是用于UIView，而不是UITableViewCell。
