不确定我做错了什么。我收到这个错误:
致命错误:在打开Optional时意外发现nil 此行中的值
self.profileImage.image = UIImage(data: data)
在我didSelectRowAtIndexPath
之后。我不想发送任何东西作为发件人,但当我尝试执行SegueWithIdentifier时,它似乎试图获取该单元格?为什么我选择它后会再次调用configureCell函数?
的ViewController
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
victim = friends[indexPath.row] as Friend!
DataService.shared.setVictim(victim!)
print("It got here with friend: \(victim!)")
performSegueWithIdentifier("commentFromSegue", sender: nil)
}
FriendsTableViewCell
class FriendTableViewCell: UITableViewCell {
@IBOutlet weak var friendName: UILabel!
@IBOutlet weak var profileImage: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
layer.cornerRadius = 5.0
}
func configureCell(friend: Friend) {
let url = NSURL(string: friend.profileImg)
if let data = NSData(contentsOfURL: url!) {
self.profileImage.image = UIImage(data: data)
// works if I comment out the above line. but does not show profile image
}
friendName.text = friend.friendName
}
}
