plist文件中添加LSApplicationQueriesSchemes数组，添加两个字符串，用于调起微信

导入依赖库SystemConfiguration.framework, libz.dylib, libsqlite3.0.dylib, libc++.dylib, Security.framework, CoreTelephony.framework, CFNetwork.framework

添加白名单 ios 微信登录sdk集成

在你的工程文件中选择Build Setting，在"Other Linker Flags"中加入"-ObjC 和 -all_load"

在Appdelegate.h中遵守协议和添加头文件

#import "AppDelegate.h"
#import "WXApi.h"

@interface AppDelegate ()<WXApiDelegate>

@end

在Appdelegate.m中的didFinishLaunchingWithOptions方法中注册微信WX_AppId是你的微信开发者平台上的appId

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    // 微信注册
    [WXApi registerApp:WX_AppId];
    return YES;
}

在Appdelegate.m中添加代理方法

// 这个方法是用于从微信返回第三方App
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*,id> *)options NS_AVAILABLE_IOS(9_0){
    
    [WXApi handleOpenURL:url delegate:self];
    
    return YES;
}

Appdelegate.m中的回调方法

[self.window showMBHUDAlertWithMessage:@"微信授权失败" hide:1.0]; 它是提示框

- (void)onResp:(BaseResp *)resp{
    
    // =============== 获得的微信登录授权回调 ============
    if ([resp isMemberOfClass:[SendAuthResp class]])  {
        NSLog(@"******************获得的微信登录授权******************");
        
        SendAuthResp *aresp = (SendAuthResp *)resp;
        if (aresp.errCode != 0 ) {
            dispatch_async(dispatch_get_main_queue(), ^{
                [self.window showMBHUDAlertWithMessage:@"微信授权失败" hide:1.0];
            });
            return;
        }
        
        NSString *code = aresp.code;
        [self getWeiXinOpenId:code];
    }
}

AppDelegate.m中用于获取token和openid

//通过code获取access_token，openid，unionid
- (void)getWeiXinOpenId:(NSString *)code{
    NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code",WX_AppId,WX_AppSerect,code];
    
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        NSURL *zoneUrl = [NSURL URLWithString:url];
        NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil];
        NSData *data1 = [zoneStr dataUsingEncoding:NSUTF8StringEncoding];
        
        if (!data1) {
            [self.window showMBHUDAlertWithMessage:@"微信授权失败" hide:1.0];
            return ;
        }
        
        // 授权成功，获取token、openID字典
        NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data1 options:NSJSONReadingMutableContainers error:nil];
        NSLog(@"token、openID字典===%@",dic);
        self.access_token = dic[@"access_token"];
        self.openid= dic[@"openid"];
        
        //         获取微信用户信息
        [self getUserInfo];
        
    });
}

APPDelegate.m用户获取微信用户信息

-(void)getUserInfo
{
    NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/userinfo?access_token=%@&openid=%@",self.access_token,self.openid];
    
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        NSURL *zoneUrl = [NSURL URLWithString:url];
        NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil];
        NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding];
        dispatch_async(dispatch_get_main_queue(), ^{
            
            // 获取用户信息失败
            if (!data) {
                [self.window showMBHUDAlertWithMessage:@"微信授权失败" hide:1.0];
                return ;
            }
            
            // 获取用户信息字典
            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
            NSLog(@"用户信息字典:===%@",dic);
            
        });
        
    });
}

在点击微信登录事件中写入

if ([WXApi isWXAppInstalled]) {
        
        //构造SendAuthReq结构体
        SendAuthReq *req = [[SendAuthReq alloc] init];
        req.scope = @"snsapi_userinfo";
        req.state = @"App";
        //第三方向微信终端发送一个SendAuthReq消息结构
        [WXApi sendReq:req];
    }else{
        
        UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"温馨提示" message:@"请先安装微信客户端" preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];
        [alert addAction:action];
        [self presentViewController:alert animated:YES completion:nil];
    }

完！！！
