For some reason I am getting an crash and I am not sure why. Everything is being pulled from FIRBase correctly. But when trying to load the user url I get a crash
printed(snapshot)
["MediaType": TEXT, "text": Test Message, "senderId": KG7b3tDTaoMwcAQAi2JI8vjj0OB2, "senderName": user1]
Optional({
email = "[email protected]";
id = KG7b3tDTaoMwcAQAi2JI8vjj0OB2;
profileImage = "gs://big-pen.appspot.com/profileImage/KG7b3tDTaoMwcAQAi2JI8vjj0OB2";
username = user1;})
My error
fatal error: unexpectedly found nil while unwrapping an Optional value
(lldb)
Here is my code.
func observeUsers(id: String){
FIRDatabase.database().reference().child("people").child(id).observeEventType(.Value, withBlock: { snapshot in
print(snapshot.value)
if let dict = snapshot.value as? [String: AnyObject] {
let avatarUrl = dict["profileImage"] as! String
//call the setupAvatar function
self.avatar(avatarUrl, messageId: id)
}
})
}
func avatar(url: String, messageId: String){
if DataService.dataService.currentUser != nil{
if url != "" {
let fileURL = NSURL(string: url )
let data = NSData(contentsOfURL: fileURL!)
let image = UIImage(data:data!) //<-----I am getting an error at this line error code: "Thread1:EXC_BAD_INSTRUCTION(code=Exc_I386_INVOP, subcode=0x0)"
let userImg = JSQMessagesAvatarImageFactory.avatarImageWithImage(image, diameter: 30)
avatarDict[messageId] = userImg
}else{
JSQMessagesAvatarImageFactory.avatarImageWithImage(UIImage(named: "cam_w.png"), diameter: 30)
}
collectionView.reloadData()
}
}
override func collectionView(collectionView: JSQMessagesCollectionView!, avatarImageDataForItemAtIndexPath indexPath: NSIndexPath!) -> JSQMessageAvatarImageDataSource! {
let message = messages[indexPath.item]
return avatarDict[message.senderId]
//return JSQMessagesAvatarImageFactory.avatarImageWithImage(UIImage(named: "cam_w.png"), diameter: 30)
}
Thanks. I have been stuck on this for two days now.
Maybe it is not a valid URL so to check it change your avatar func to:
