IOS implementation of Third-party micro-letter Login Method Instance resolution (latest most full) _ios

Project Address: Https://github.com/zhonggaorong/weixinLoginDemo

The latest version of the micro-letter login implementation steps to achieve:

1. In the micro-letter OAuth2.0 Authorized login access, the micro-trust open platform to register the developer account, and have an audited mobile applications, and obtain the corresponding AppID and Appsecret, apply for micro-letter login and through the audit, you can start the access process. Address: Click to open the link

2. Download the latest SDK address: Click on the Open link

The SDK contents are as follows:

Structure resolution:

From top to bottom, in turn, explain:

1. Static library, direct drag into the project.

2. Ready.text to see for himself

3. Authorized SDK.

4. The class where the login method resides.

5. Some commonly used object classes.

iOS micro-Letter Login considerations:

1, the current mobile application of micro-letter login only provides native login mode, need users to install micro-letter client can be used together.

2, for Android applications, it is recommended to always display the micro-letter login button, when the user's mobile phone does not install the micro-trust client, please guide users to download and install the micro-letter client.

3, for iOS applications, taking into account the iOS Application Store audit guide, the relevant provisions, recommended developers to the letter login, first detect whether the user's phone has been installed micro-letter client (using the SDK iswxappinstalled function), not installed users hide the micro-letter login button, Only provide other login methods (such as mobile phone number registration login, visitors login, etc.).

iOS micro-Letter Login Overview Process:

1. When a third party initiates a micro-letter authorization login request, the micro-trust user authorizes the third party to apply, the micro-letter will pull up the application or redirect to the third party website, and with the authorization temporary bill code parameter;

2. Through the code parameters plus AppID and Appsecret, through the API to exchange for Access_token;

3. Interface calls through Access_token to obtain user basic data resources or to help users achieve basic operations.

The next step is to get to the point:

1. Configuration Engineering

1. Create a new project.

2. Drag all the. h files and static libraries in the downloaded SDK into the project.

3. Join a dependency library

4. Url-types (join AppID)

target - Info - URL Types

5. White List

When this error occurs in a program

-canopenurl:failed for URL: ' weixin://app/wx5efead4057f98bc0/'-error: ' This app isn't allowed to query for scheme Weix In "

It shows that no white list has been added against IOS9. Add Lsapplicationqueriesschemes to Info.plist file

App transport Security This is to let the program or HTTP to make the request.

Lsapplicationqueriesschemes This is the white list that adds micro-letters.

6. Compiling now should be no problem.

2. Finally to the exciting part of the code. directly on the code.

The above is a small set of iOS to introduce the implementation of Third-party micro-Letter Login Method Example (the latest most complete), hope to help everyone, if you have any questions please give me a message, small series will promptly reply to everyone.
