I need some help. I use AlamofireImage UIImageView extension to load some icons inside UITableView.
My project use some third party library written in Objective-C.
Code:
class TableCell: UITableViewCell {
#IBOutlet weak var logo: UIImageView!
#IBOutlet weak var name: UILabel!
func setData(provider: ServiceProvider) {
name.text = provider.name
let url = NSURL(string: provider.logoUrl)!
self.logo.af_setImageWithURL(url)
}
override func prepareForReuse() {
super.prepareForReuse()
logo.af_cancelImageRequest()
logo.layer.removeAllAnimations()
logo.image = nil
}
}
Error:
-[UITableViewCellContentView af_cancelImageRequest]: unrecognized selector sent to instance 0x787ea430

I am getting a '-[_SwiftValue mergeType]: unrecognized selector sent to instance' error whenever I try to save a managed object context after doing a delete or an update of a record. For example:
context.delete(managedObject)
follow by
context.save()
and yes, context.save() is in a do-try-catch.
Records insert just fine, but the delete is throwing an exception. Stack trace is as follows:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_SwiftValue mergeType]: unrecognized selector sent to instance 0x60800005b0f0'

Trace starts right after it leaves my code.
Any insight would be helpful.
You may get this error when you use code like this, to set a merge policy:
context.mergePolicy = NSMergePolicyType.mergeByPropertyStoreTrumpMergePolicyType
Instead use this:
context.mergePolicy = NSMergePolicy(merge: .mergeByPropertyStoreTrumpMergePolicyType)
Why do I get a Thread:1 Signal SIGAGBRT within this code? I don't know what to change to fix the error. The application starts and as soon as I press the button the app cancels out and gives me an error.

The crucial information is
[DegreeCL.ViewController btnPressed:]: unrecognized selector sent to instance ...'
That means in Interface Builder there is somewhere a dead connection to an action btnPressed. Remove it.
You can search for btnPressed with ⇧⌘F.
SIGABRIT - signal is sent due to many reasons but in this case i think you have problem with Memory.
You should turn on All Exeptions with option of po $arg1 it will identify the error.
Select your button from interface builder, then select connection inspector from utilities and check that if you have extra connected action method should be there, remove it by clicking x and your issue will be solved!
It's should be btnPressed as per your crash log!
I've this error, when I try to use UIColor : [UICachedDeviceRGBColor stringByReplacingOccurrencesOfString:withString:]: unrecognized selector

The crash log says that you try send message to UICachedDeviceRGBColor class but it doesn't have method with name stringByReplacingOccurrencesOfString:withString: and it doesn't inherit from NSString. This method declare only in NSString class.
I am trying to create a simple Firebase application, and I have previously done so on Android. I am learning swift and was following the basic tutorials provided by Firebase.
I have successfully added Firebase through CocoaPods, however I am having trouble reading the result:
import UIKit
import Firebase
class ViewController: UIViewController {
#IBOutlet var mLabel: UILabel!
var myRootRef = Firebase(url:"https://ios-weather-practice.firebaseio.com")
override func viewDidLoad() {
super.viewDidLoad()
myRootRef.observeEventType(.Value, withBlock: {
snapshot in
if let baseResult = snapshot.value.objectForKey("ios-weather-practice") {
self.mLabel.text = baseResult as? String
}
})
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Firebase Database:
Observing by .Value will read in the entire contents of a node.
So if your structure is like this
myRootRef
iso-weather-practice: "sunny"
Your event will be ok and it could be read like this
self.mLabel.text = baseResult as? String
However, that's not usually how a Firebase structure would appear. It would be more like this
myRootRef
-JYa6s6gij900is
date: "20160413"
weather: "sunny"
-JY9398iias98o4
date: "20160414"
weather: "blowing snow"
and in that case. .Value will read in that entire node, and the snapshot will contain multiple nodes (as key:value pairs)
So here's how to handle it:
ref.observeEventType(.Value, withBlock: { snapshot in
for child in snapshot.children {
if let w = child.value.objectForKey("weather") as? String {
print(w)
}
}
})
output will be
sunny
blowing snow
Try this:
if let baseResult = snapshot.value as? String {
self.mLabel.text = baseResult
}
I created a function. This function is called by a button. If I press the button the app crashes and throws the following error:

this is the function which is crashing if it's called:
func setDate(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
switch editingStyle {
case .Delete:
let appDel:AppDelegate = UIApplication.sharedApplication().delegate as AppDelegate
let context:NSManagedObjectContext = appDel.managedObjectContext!
context.deleteObject(daten[indexPath.row] as NSManagedObject)
daten.removeAtIndex(indexPath.row)
context.save(nil)
self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
default:
let mySelectedCell:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
mySelectedCell.detailTextLabel?.text = dateLabel.text
self.sideBar.alpha = 0
return
}
}
This line tells you everything you need to know:
-[MyApp.ViewController setDate]: unrecognized selector sent to instance 0x7fbbb9e458a0
Your ViewController class doesn't have a method called setDate or a property called date.
As far as I can tell, the function you posted has nothing to do with this error. It never calls setDate.
