preface

  • It took me half a day to sort through the library of tools I normally use, detailing each method attribute
  • Doraemon tool library, just like doraemon pocket, there are endless unexpected various props for us to use

Function is introduced

This library mainly contains several major sections: UIKit class, Foundation class, Language multi-language class, Classes particle effect related, Control custom Control

  • UIButton: Image mixing, click event encapsulation, expand click field, time interval limit, countdown, click particle effect, etc
  • UIView: Gesture encapsulation, rounded gradients, Xib properties, basic animation encapsulation, etc
  • UITextView: Input box extension, word limit, undo processing, get text internal hyperlinks
  • UITextField: placeholder color, lines, graphic processing, etc
  • UILabel: Rich text, quick display of text position
  • UIImage: screenshot and cropping, image compression, mask processing, image stitching, image size processing, filter rendering, flooding algorithm, etc
  • UIImage: TWO-DIMENSIONAL code, bar code generation, dynamic graph play, watermark processing and so on
  • Runtime: lists, method exchange, dynamic inheritance, etc
  • UIDevice: System-related properties,
  • Language: Supports multiple languages and Xib shortcut Settings
  • Foundation: Array and dictionary anti-collapse processing, array algorithm processing, predicate correlation, encryption and decryption, etc
  • Image processing packaging, Hough correction, feature extraction, morphological processing, filter processing and so on

Foundation I also collate encapsulated exception handling Crash protectionKJExceptionDemo
