Why is my keyboard being loaded whenever I load my UIImagePickerController view? - ios

Question

I have a UIActionSheet for selecting between the camera or the photo library to embed an image into a UITextView but for whatever reason it's loading the keyboard. I force close the keyboard on press of the left button of the bar surrounding the UITextView but when I press photo library I opens and closes the keyboard before pushing to the image picker VC.
override func didPressLeftButton(sender: AnyObject?) {
let cameraMenu = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
let photoLibrary = UIAlertAction(title: "Photo Library", style: .Default, handler: { (UIAlertAction) in
self.openPhotoLibrary()
})
let takePhoto = UIAlertAction(title: "Open Camera", style: .Default, handler: { (UIAlertAction) in
self.textView.endEditing(true)
self.openCamera()
})
let cancel = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
cameraMenu.addAction(photoLibrary)
cameraMenu.addAction(takePhoto)
cameraMenu.addAction(cancel)
self.presentViewController(cameraMenu, animated: true, completion: nil)
}
func openPhotoLibrary() {
imagePicker.sourceType = .PhotoLibrary
imagePicker.allowsEditing = false
presentViewController(imagePicker, animated: true, completion: nil)
}
func openCamera(){
imagePicker.sourceType = .Camera
imagePicker.showsCameraControls = true
presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
// Image resizing
let textViewWidth: CGFloat = self.textView.frame.size.width - 20
let percentResize = textViewWidth / pickedImage.size.width
let toBeExportedHeight = pickedImage.size.height * percentResize
let resizedImage = ImageManipulationManager.sharedInstance.resizeImage(exportedWidth: Int(textViewWidth),exportedHeight: Int(toBeExportedHeight), originalImage: pickedImage)
// Storage into TextView
let attachment = NSTextAttachment()
attachment.image = resizedImage
let attString = NSAttributedString(attachment: attachment)
textView.textStorage.insertAttributedString(attString, atIndex: textView.selectedRange.location)
pastedImageLocations.append(textView.selectedRange.location)
textView.selectedRange.location = textView.selectedRange.location + 1
textView.textStorage.insertAttributedString(NSAttributedString(string: "\n"), atIndex: textView.selectedRange.location)
textView.selectedRange.location = textView.selectedRange.location + 1
textView.font = UIFont.systemFontOfSize(16.0)
// Image Caching
if let data = UIImageJPEGRepresentation(pickedImage, 0.50) {
socketMessages.append(["data": data])
haneke.set(value: data, key: String(unsafeAddressOf(attachment.image!)))
print("Image cached as \"\(String(unsafeAddressOf(attachment.image!)))\"")
}
}
dismissViewControllerAnimated(true, completion: nil)
self.textView.becomeFirstResponder()
}

Answer 1

Found the solution.
I had to change
dismissViewControllerAnimated(true, completion: nil)
self.textView.becomeFirstResponder()
to
dismissViewControllerAnimated(true) {
self.textView.becomeFirstResponder()
}

You can do some changes by adding this -
override func didPressLeftButton(sender: AnyObject?) {
let cameraMenu = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
let photoLibrary = UIAlertAction(title: "Photo Library", style: .Default, handler: { (UIAlertAction) in
self.view.endEditing(true) //**------ Add this
self.openPhotoLibrary()
})
let takePhoto = UIAlertAction(title: "Open Camera", style: .Default, handler: { (UIAlertAction) in
self.view.endEditing(true) //**------ Add this
self.openCamera()
})
let cancel = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
cameraMenu.addAction(photoLibrary)
cameraMenu.addAction(takePhoto)
cameraMenu.addAction(cancel)
self.presentViewController(cameraMenu, animated: true, completion: nil)
}
