[iOS]分享文件到QQ好友或微信好友

APP中需要将文件分享给QQ和微信好友，常用下面这两种方式。
1、使用系统的UIActivityViewController类发送
2、使用QQ和微信的API分享

UIActivityViewController分享的样式如下：

下面主要一下分享文件到QQ和微信好友如何实现

[API文档]

QQ互联
https://wiki.connect.qq.com/
微信开放平台
https://open.weixin.qq.com

[开发信息编辑]

URL Schema填写QQ+转化成十六进制的App ID（附上一个转换网址），转换后的App ID不足八位则前面补0凑齐。

若公司有多个app,这里设置Universal Links时需要用path区分. 比如:

https://www.jadinec.com/jiding/
https://www.jadinec.com/jisu/

[Universal Links]

QQ SDK版本V3.3.6、微信SDK版本V1.8.6.1之后，接入SDK后应用中需要处理Universal Links拉起APP功能。
不处理Universal Links时，微信还能正常分享，但QQ分享时会报错“设备未授权 (错误码:25105)”。

创建并上传apple-app-site-association文件到服务器

创建一个名为apple-app-site-association的文件，没有后缀，但是内容是json格式。apps必须设置为[]，appID的结构为TeamID.bundleID，其中 Team ID 在第一步已经获取到了，bundleID 可以设置唯一ID也可以设置通配符ID，关键就是Bundle ID是否设置了Associated Domains Enable。
上传时的MINI TYPE一定是application/json。上传到服务器的根目录下或者.well-known目录下，且能通过网址https://<fully qualified domain>/apple-app-site-association或者https://<fully qualified domain>/.well-known/apple-app-site-association访问这个文件，不论是否是下载还是直接在浏览器中能直接看到文件内容。

appID的格式是Team ID.Bundle ID，其中Team ID可以登录开发网站(https://developer.apple.com),点击App IDS从列表进入详情查看（如图）。

单个APP时配置:

{"applinks": {"apps": [],"details": [{"appID": "CBQFB991WG.com.maojitech.jiding","paths": ["*","/qq_conn/101888113/*"]}]}
}

多个APP时配置:
paths中第一个对象是微信的path，第二个是qq的path

{"applinks": {"apps": [],"details": [{"appID": "CBQFB991WG.com.maojitech.jiding","paths": ["/jiding/*","/qq_conn/1019489322/*"]},{"appID": "CBQFB991WG.com.maojitech.jisu","paths": ["/jisu/*","/qq_conn/101971011/*"]}]}
}

[代码处理]

详细的集成可以去看集成文档，这里用部分代码说明一下操作。
先添加Associated Domains

AppDelegate

#import "AppDelegate.h"
#import <TencentOpenAPI/TencentOAuth.h>
#import "WXApi.h"static NSString *TencentAppId = @"101880000";
static NSString *JBSWeixinAppId = @"wx635f2582ac160000";@interface AppDelegate () @end@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...// QQ分享[[TencentOAuth alloc] initWithAppId:TencentAppId andDelegate:nil];// 微信分享[WXApi registerApp:JBSWeixinAppId withDescription:@"甲丁"];
}#pragma mark - QQ分享- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {NSString *string =[url absoluteString];if ([string hasPrefix:JBSWeixinAppId]){return [WXApi handleOpenURL:url delegate:self];}else if ([string hasPrefix:TencentAppId]){return[TencentOAuth HandleOpenURL:url];}return NO;
}- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {NSString *string =[url absoluteString];if ([string hasPrefix:JBSWeixinAppId]){return [WXApi handleOpenURL:url delegate:self];}else if ([string hasPrefix:TencentAppId]){return[TencentOAuth HandleOpenURL:url];}return NO;
}- (void)onReq:(BaseReq *)req {}- (void)onResp:(BaseResp *)resp {if ([resp isKindOfClass:[SendMessageToWXResp class]]) {switch (resp.errCode) {case WXSuccess:// 分享成功break;case WXErrCodeUserCancel:// 用户取消分享break;default:// 分享失败break;}}
}@end

QQ的SDK分享文件到好友现在实现不了，这里采用新闻的方式在分享。

//QQ分享
#import  <TencentOpenAPI/QQApiInterfaceObject.h>
#import <TencentOpenAPI/TencentOAuth.h>
#import <TencentOpenAPI/QQApiInterface.h>@weakify(self);

} backAction:^{@strongify(self);[self.navigationController popViewControllerAnimated:YES];
}];/// 文件 分享到QQ
- (void)tencentShare {NSString *link = _url?:@"";NSString *title = _fileName?:@"";//NSData *fileData = [NSData dataWithContentsOfURL:[NSURL URLWithString:link]];//NSData *imgData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://dss1.bdstatic.com/70cFvXSh_Q1YnxGkpoWK1HF6hhy/it/u=3471770554,1562873257&fm=26&gp=0.jpg"]];dispatch_async(dispatch_get_main_queue(), ^{if (![TencentOAuth iphoneQQInstalled]) {// [self showAlert:@"检查到您没有安装腾讯QQ，请先安装QQ再分享。"];[MBProgressHUD showError:@"检查到您没有安装腾讯QQ，请先安装QQ再分享。"];} else {/*NSURL *newsUrl = [NSURL URLWithString:[link stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];// QQ无法直接发送文件QQApiFileObject *newsObj = [QQApiFileObject objectWithData:fileDatapreviewImageData:niltitle:titledescription:title];newsObj.fileName = title;[newsObj setCflag:kQQAPICtrlFlagQZoneShareOnStart];*/// 使用网络连接的方式分享文件NSString *imgName = @"";if ([title containsString:@".xlsm"] || [title containsString:@".xls"] || [title containsString:@".XLSM"] || [title containsString:@".XLS"]) {imgName = @"Microsoft-Excel";} else if ([title containsString:@".docx"] || [title containsString:@".doc"] || [title containsString:@".DOCX"] || [title containsString:@".DOC"]) {imgName = @"Microsoft-WORD";} else if ([title containsString:@".pptx"] || [title containsString:@".ppt"] || [title containsString:@".PPTX"] || [title containsString:@".PPT"]) {imgName = @"Microsoft-PPT";} else if ([title containsString:@".pdf"] || [title containsString:@".PDF"]) {imgName = @"Microsoft-pdf";}NSData *imageData;if ([imgName isEqualToString:@""]) {} else {UIImage *image = [UIImage imageNamed:imgName];imageData = UIImagePNGRepresentation(image);}// QQApiURLObject *newsObj = [QQApiURLObject objectWithURL:[NSURL URLWithString:link] title:title description:@"" previewImageData:imageData targetContentType:QQApiURLTargetTypeNews];// [newsObj setCflag:kQQAPICtrlFlagQQShare];QQApiNewsObject *newsObj = [QQApiNewsObject objectWithURL:[NSURL URLWithString:link] title:title description:nil previewImageData:imageData];[newsObj setCflag:kQQAPICtrlFlagQQShare];SendMessageToQQReq *req = [SendMessageToQQReq reqWithContent:newsObj];QQApiSendResultCode sent = [QQApiInterface sendReq:req];// QQApiSendResultCode sent = [QQApiInterface SendReqToQZone:req];}});
}/// 文件 分享到微信

}

[效果]

配置完成后，在备忘录输入链接，长按后会提示”在‘APP‘中打开“。用Safari打开网址时，顶部也会提示在”APP“中打开。
