微信大大的一些用于登录、分享和支付的硬性前提要求:
- 不论是接入微信的登录、支付还是分享都必须要提前进行
应用审核。 - 只有审核完成后才能有AppID和App Secret。
- 并且如果需要获取更高的权限，必须要进行申请审核 (还要交钱)。
-
微信开发者平台提交的应用中的审核官网地址可填如下: http://www.apple.com/cn/itunes/ 公司官网地址即可。

微信登录、分享和支付的SDK，包含如下文件:

接入微信给工程添加相应的配置
1.开发者需要链接下面的系统库: Link Frameworks and Libraries
iOS-微信-linkFramework.png
2.在工程文件中选择 Taeget-->Build Setting，在"Other Linker Flags"中加入"-Objc -all_load"。 在 Search Paths 中添加 libWeChatSDK.a ，WXApi.h，WXApiObject.h，文件所在位置。
3.在Xcode中，选择你的工程设置项，选中 TARGETS-->info-->URL type “添加“ URL scheme”为你所注册的应用程序id（应用程序AppID在微信开发者平台创建移动应用）
iOS-微信SDK-URLScheme.png
4.在Xcode中，选择你的工程设置项，选中“TARGETS”一栏，在“info”标签栏的 LSApplicationQueriesSchemes 添加 weixin和wechat两个白名单
iOS-微信SDk-白名单添加.png
5.允许网络传输: iOS9中新增App Transport Security（简称ATS）特性, 主要使到原来请求的时候用到的HTTP，都转向TLS1.2协议进行传输。这也意味着所有的HTTP协议都强制使用了HTTPS协议进行传输。需要在Info.plist新增一段用于控制ATS的配置：
NSAppTransportSecurity
NSAllowsArbitraryLoads
iOS-微信SDK-ATS.png
使用微信SDK具体实现代码: (编写此文档时使用WeChatSDK 1.8.3版本)
AppDelegate.m 中注册微信创建的移动应用ID
注意： 在未获得创建的移动应用ID时，可以使用 Wechat SDK Demo的AppID和Bundle ID操作实现相应流程
// 注册AppID
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[WXApi registerApp:@"wxd930ea5d5a258f4f"];
}
// 微信回调
// iOS 9.0之后
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options{
NSLog(@"log-- xxx openURL:xxx");
/* 微信登录和分享 */
if ([WXApi handleOpenURL:url delegate:[[WeChatHandleURLDelegate alloc]init]]) {
return YES;
}
}
// iOS 9.0 之前
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
/* 微信登录和分享 */
// `WeChatHandleURLDelegate ` 为 `WXApiDelegate`代理文件

}
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{

调用WeChat 微信登录方法
目前移动应用上德微信登录只提供 原生的登录方式，需要用户 安装微信客户端 才能配合使用。
对于iOS应用,考虑到iOS应用商店审核指南中的相关规定，建议开发者接入微信登录时，先检测用户手机是否已经安装
微信客户端(使用sdk中的isWXAppInstall函数),对于未安装的用户隐藏微信 登录按钮，只提供其他登录方式。
以下代码内容，类似于WeChat SDK Demo内容，但不完全等同。
