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

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

**The author in the previous period of time on this issue with the background of the docking of people, and finally finally determine the problem is our encryption, although all for the same species, but there are essential differences. Below I briefly describe the difference and enclose the main code:1. Commonly used AES encryption instructionsWe commonly used in the de

Preface
As you know, categories are a way to add new methods to existing classes, using the dynamic Run-time allocation mechanism of OBJECTIVE-C, you can add new methods to existing classes, the way you add new methods to existing classes, called Category Catagory, and he can add new methods to any class. Include classes that do not have source code. Categories allow you to do the
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

Reading other people's code (some excellent source) can always find some common keywords, with the accumulation of programming experience most still know what it means, but in terms of conceptual and specific usage is still somewhat vague, so deliberately collated the next three more common keywords-- Const/static/extern.

The first
Multiple languages typically have two approaches in an application:One, the procedure provides to the user oneself choice opportunity;Second, according to the current user mobile device language automatically switch our app to the corresponding language.
The first approach is relatively simple and completely rely on their own play, here is mainly about the second approach, mainly divided into a number of points:
