1、通知
NotificationCenter.default.addObserver(self,
selector: #selector(KMPlaceholderTextView.textDidChange),
name: NSNotification.Name.UITextViewTextDidChange,
object: nil)
改成
NotificationCenter.default.addObserver(self,
selector: #selector(KMPlaceholderTextView.textDidChange),
name: UITextView.textDidChangeNotification,
object: nil)
2、压缩图片质量
let imageData = UIImageJPEGRepresentation(img, 0.25)!
改成
let imageData = img.jpegData(compressionQuality: 0.25)!
