the written Jkencrypt Https://github.com/jukai9316/JKEncrypt. The following 3DES implementations are resolved below, and then again, how to use Jkencrypt. Note: The padding is different. In the process of interacting with the background, because Java inside the use of pkcs5padding, and iOS only kccoptionpkcs7padding, so with kccoptionpkcs7padding | Kccoptionecbmode is equivalent to pkcs5padding. The following is the implementation of 3DES 256 in

About the iOS modular development solution Online also has some introduction, but the actual implementation in the concrete instance but rarely see, plan to write system articles to introduce my understanding of the modular solution, which will contain some about decoupling, routing, encapsulation, private pod management, etc. And write an instance of the project put in git for open source [Jiamoduledemo], which now has some encapsulated functional mo

iOS friends know or hear about runtime, which is much like the reflection mechanism of Java , but the function is much better than the reflection of Java . By Runtime we can dynamically add attributes, member variables, methods , and read and write access to a class. Introduction of runtime Runtime short run time. OC is the run-time mechanism , that is, some of the mechanisms at run time, the most important is the message mechanism. For the C langu

There are many times in iOS where you need to use the rounded button of the specified style, and here is UIButton the method for creating rounded buttons To set the 4 corners of a button: Top Left:UIRectCornerTopLeft Lower left:UIRectCornerBottomLeft Top right:UIRectCornerTopRight Bottom right:UIRectCornerBottomRight Sample code: UIButton *button = [[UIButton alloc] Initwithframe:cgrectmake (n, M,)]; Button.backgroundcolor = [Uicolor ora

This example for you to share the iOS drawer effect development examples for your reference, the specific contents are as follows Add three view to the controller displayed on the window (add only 2 view if you only need to slide one side) Declare three view first #import "ViewController.h" @interface viewcontroller () @property (nonatomic, weak) UIView *mainv; @property (nonatomic, weak) UIView *leftv; @property (nonatomic, weak) UIView *

The example of this article introduces the iOS clock development process, for your reference, the specific contents are as follows The idea is to use calayer implicit animation to achieve. Because the UIView layer, which is a manually created layer, is animated by default when its properties are changed, these properties are also called animated properties. such as bounds, backgroundcolor, position. The clock inside the dial is a uiview, and the thr

iOS uses the photo picker (uiimagepickercontrollerdelegate) to save to the data library, the image compression First look at the Uiimagepickercontrollerdelegate protocol, mainly using iOS-built graphics to select the controller -(void) Imagepickercontroller: (Uiimagepickercontroller *) Picker Didfinishpickingmediawithinfo: (nsdictionary *) info Get a picture

IOS crash log backtrace symbol iOS crash log with dSYM files can find the crash of BackTrace, which is the most important information to solve the crash. If you are packaging on the same Mac, import crash log will automatically sign BackTrace, you can see the method name, file name and line number However, sometimes the version of the package is not packaged on your Mac, Xcode can't find the corresponding

iOS provides support for using other app preview files, which is document interaction Controller. In addition, iOS also supports file associations, allowing other programs to call your app to open some sort of file. And, starting with 4.2, the Quick look framework provides built-in printing for a variety of documents. You can refer to the Documentinteraction Controller class reference as well as the Quick L

Lead: The evolution of the architecture is to serve the continuous development of the business, the architecture can not be separated from the business, this is the most basic starting point. 58 City IOS clients as business volume and user volume continue to grow, architecture is also constantly challenged, what kind of architecture to adapt to these changes, the technical staff is also a big test. The architecture of the app has undergone a total of

React-native in the development engineering also has many functions which can not achieve, this needs to use the native application to realize, React-native realizes and the iOS native interaction only needs to carry on the following several steps. 1, Import rctbridgemodule header file #import 2, the introduction of the agreement #import 3.
