如果根据下面的方法还没搞定的朋友，欢迎下方留言或者在Creator官方群里Q我群昵称“小浣熊不是猫”
下一个篇章就是支付，分享这块了哦。

一、js调用oc

看这里：js调用oc

二、oc调用js

看这里：oc调用js

三、发布ios工程

在creator中构建ios项目即可，然后将微信的sdk拷贝到IOS项目的ios目录

四、ios9以上build会报错，需要修改源码

错误提示：Call to unavailable function 'system': not available on iOS

解决办法：

五、编写调用微信接口的几个关键函数

我的调用微信的接口类是：WXApiManager.h和WXApiManager.mm

WXApiManager.h:

**#import#import "WXApi.h"
@interface WXApiManager : NSObject{** 
}

+(instancetype)sharedManager;

+(void)RegisterAppID:(NSString*)app_id;

+(void)SendAuthRequest:(NSString*)scope State:(NSString*)state;

+(BOOL)ShareToChatScene:(NSString*)content_txt;

+(BOOL)ShareToFriendCircle:(NSString*)content_txt;

+(BOOL)ShareLinkToChatScene:(NSString*)content_link Title:(NSString*)title_txt Description:(NSString*)desc_txt;

+(BOOL)ShareLinkToFriendCircle:(NSString*)content_link Title:(NSString*)title_txt Description:(NSString*)desc_txt;

+(BOOL)ShareImageToChatScene:(NSString*)path;

+(BOOL)ShareImageToChatScene:(NSString*)file_path Title:(NSString*)title_txt Description:(NSString*)desc_txt;

+(void)StartPay:(NSString* )partner_id PrepayId:(NSString*)prepay_id NonceStr:(NSString*)nonce_str TimeStamp:(UInt32)timestamp Sign:(NSString*)sign;

+(BOOL)CheckWXInstalled;

+(NSString *) getIPWithHostName:(const NSString *)hostName;

+(UIImage*)scaleToSize:(CGSize)size Target:(UIImage*)target_img;

六、配置微信sdk环境

1).引入.a文件,选择工程->build Phases->点击Link Binary With Libraries 下方的“+”弹出的对话框选择Add other，加入libWechatSDK.a

image image

2).将WeChatSDK1.7引入到工程里，从目录拖拽到工程里，选择引用的方式

image

3).加入头文件的搜索目录

image

在Header Search Paths:加入 $(PROJECT_DIR)/ios/WeChatSDK1.7.5

在Library Search Paths:加入 $(PROJECT_DIR)/ios/WeChatSDK1.7.5

在User Header Search Paths:加入 $(PROJECT_DIR)/ios/WeChatSDK1.7.5

4).配置URL Types:选择工程->选择info

image

5).修改info.plist
增加

    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>weixin</string>
    </array>

七、发布到iphone或者ipad 测试

我发布的时候选择的ios11的系统版本。
另外，调用的获取微信好友信息的流程（Js层的调用顺序，见andoird微信登陆篇，这块的获取顺序，微信官方已经讲的很明白了，这里不赘述）到这里，我的测试已经成功获取到了微信用户信息了，花了一天的时间，不过还算顺利哦。
