Swift线程1：当我尝试更改uilabel.text时为EXC_BAD_INSTRUCTION

Question

I know there are a lot of Stack Overflow questions like this out there, but none of the answers I can find work for me. I am using a custom UITableViewCell class called chillerCell . Here is its code:

import UIKit

class chillerCell: UITableViewCell {

    @IBOutlet weak var iconLabel: UILabel!
    @IBOutlet weak var boldLabel: UILabel!
    @IBOutlet weak var italicLabel: UILabel!

    func configureCellWithEvent(event: Event){
        boldLabel.text = "\(event.eventName)"
        italicLabel.text = "\(event.eventDescription)"
    }
}

I get the Thread 1 runtime error on the line boldLabel.text = "\\(event.eventName)"

I made my own Event class, and yes, event.eventName and event.eventDescription are of type String and are not Nil .

Edit: I forgot to mention, my boldLabel and italicLabel are not plain text, but attributed text.

Answer 1

Try this, it would work if event object having eventName & eventDescription as String:

func configureCellWithEvent(event: Event){
    var attributedString = NSMutableAttributedString(string:"(event.eventName)") and boldLabel.text = attributedString
    boldLabel.text = attributedString
    italicLabel.text = attributedString
}

Answer 2

删除标签并再次创建其他标签，这对我有用。
