App crash when MFMessageComposeViewController is initialisation - ios

I want to send a message through my app. I call the following method on click
#IBAction func sendMessage(_ sender: Any) {
if (MFMessageComposeViewController.canSendText()) {
let composeVC = MFMessageComposeViewController()
composeVC.messageComposeDelegate = self
// Configure the fields of the interface.
composeVC.recipients = ["4085551212"]
composeVC.body = "Hello from California!"
// Present the view controller modally.
self.presentViewController(composeVC, animated: true, completion: nil)
}
}
The problem is if I run the app on device, it crashes at MFMessageComposeViewController initialisation i.e.
let composeVC = MFMessageComposeViewController()
If I run the app in simulator, it crashes on presentation i.e.
self.present(composeVC, animated: true, completion: nil)

Any help would be appreciated.

Okay,
When you run it in iPhone : The crash log clearly states that "Only RGBA or White color spaces are supported in this situation." So by hint I would say you are assigning color somewhere, (Some Global tint, navigation bar tint) , which doesn't apply to a MFMessageComposeViewController, hence its crashing.
When you run it in the simulator :
if (MFMessageComposeViewController.canSendText()), this line will prevent it from initialising the MFMessageComposeViewController, in the simulator as it cant send text, hence when you try to present it, its not yet initialised and crashing.
On a second thought, as per your code : self.presentViewController(composeVC, animated: true, completion: nil), this line should not even be called while running in the simulator as this line is inside the if statement, which wont get through.
Also change the tint color or any while initialising the controller, and tell me what the results are.

NSInternalInconsistencyException - Animator is already stopped

Currently getting the following runtime exception
libc++abi: terminating with uncaught exception of type NSException
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Animator <UIViewPropertyAnimator(0x600003f24200) [stopped] interruptible> is already stopped!'
Because of the following line of code
// other code up here that modifies offsetAnimator
...
// stop any current running animations on offset
if let offsetAnimator = offsetAnimator {
offsetAnimator.stopAnimation(false) // this line is where the exception gets raised
offsetAnimator.finishAnimation(at: .end)
}
What is perplexing, however, is why this error is NOT readily reproducible
// doing this doesn't always result in an error
if let offsetAnimator = offsetAnimator {
offsetAnimator.stopAnimation(false)
offsetAnimator.finishAnimation(at: .end)
offsetAnimator.stopAnimation(false)
offsetAnimator.finishAnimation(at: .end)
}
What on earth is happening? Can someone explain to me why this error is occurring?
Why does it seem to only happen sporadically? Shouldn't calling .stop twice always trigger it?

Uncaught NSException when battery level changes

I'm working on a simple app that just shows the time and battery level. The time part works flawlessly, and I can monitor the battery level, but the battery indicator icon crashes the app when there are any changes to the device's battery. Here's the relevant code:
override func viewDidLoad() {
super.viewDidLoad()
UIDevice.current.isBatteryMonitoringEnabled = true // Enable battery monitoring
NotificationCenter.default.addObserver(self, selector: Selector(("batteryStateDidChange:")), name: NSNotification.Name.UIDeviceBatteryStateDidChange, object: nil) // Add battery state checker
NotificationCenter.default.addObserver(self, selector: Selector(("batteryLevelDidChange:")), name: NSNotification.Name.UIDeviceBatteryLevelDidChange, object: nil) // Add battery level checker
// Get the battery level
var batteryLevel: Int {
return Int(UIDevice.current.batteryLevel * 100)
}
update()
timer = Timer.scheduledTimer(timeInterval: 5, target: self, selector: #selector(self.update), userInfo: nil, repeats: true) // Start the timed scheduler
}
Here's the error:
2017-06-24 11:45:27.783761-0500 SimpleClock[1484:846193] -[SimpleClock.ViewController batteryLevelDidChange:]: unrecognized selector sent to instance 0x15dd15bc0

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)
The -[SimpleClock.ViewController batteryLevelDidChange:]: unrecognised selector error indicates that the batteryLevelDidChange function is missing in the code or as Vadian commented, the signature is wrong.
Use an if condition before adding the observer for batteryStateDidChange: selector. You can use respondsToSelector: method for this. This way you can make sure if the selector is implemented.
Also you need to implement the selector in your source file as I can't see it in your code, hence giving the unrecognised selector error.
Hope it helps!

Customize camera overlay in applozic

I am using applozic chat sdk for ios and sending images , video successfully . My requirement is to change camera overlay. When I try to add overlay on camera it crashes.
let camaraObj : ALImagePickerController = ALImagePickerController()
let overlay =UIView(frame: UIScreen.mainScreen().bounds)
overlay.backgroundColor = UIColor.redColor()
camaraObj.cameraOverlayView = overlay
Crash log: libc++abi.dylib: terminating with uncaught exception of type NSException.
Any help ?
Looks like you are not setting the sourceType. ALImagePickerController is used for sending pictures from photos only. You need to explicitly set source type if you want to use it for camera.
i.e. self.mImagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
We just tried the same and got below exception:

App crashes when trying to resign keyboard

Since I updated to the latest Xcode 6 beta, I have been having issues with closing the keyboard. My app is crashing each time I try to close the keyboard, even though I have used the same code for ages and it used to work fine.
Here is what I have:
#IBAction func viewTapped(sender : AnyObject) {
//Closes keyboard when user touches screen.
transactionDateInput.resignFirstResponder()
transactionNameInput.resignFirstResponder()
textField.resignFirstResponder()
notesField.resignFirstResponder()
UIView.animateWithDuration(1.5, animations: {
self.valueEnter.alpha = 0
self.dateEnter.alpha = 0
self.notesDone.alpha = 0
})
}
Someone suggested changing it to something like this:
if (transactionDateInput.isFirstResponder() == true){
transactionDateInput.resignFirstResponder()
}
but that makes no difference. Anyone have any suggestions? Here is the error:
AffordIt[4445:1334424] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[AffordIt.SecondViewController textFieldShouldReturn:]: unrecognized selector sent to instance 0x7fb169666880'
Check your Text Field outlet delegate (right click to Text Field)
there should be delegate to your UIViewController!

UITextFieldView markedTextRange crash on iOS4?

My apps use UITextFieldView to receive input method from user and work fine on iOS6/iOS7. and I am using the following code to prevent user input chinese/japanese/something like that. Method to detect the real input words:

//crash here if device iOS version at 4.3
UITextRange *selectRange = [textField markedTextRange];
if (selectRange == nil)
//get word to do something...
