社交分享 应用间跳转

• 通过用户的分享,让更多的人去了解和使用这个APP
• 目前移动互联网应用程序推广的重要手段之一
• 属于口碑营销的范围
  在iOS中,实现"社交分享"的方法
  自己编写各个平台的分享代码(代码量较多)
  利用iOS自带的Social.framework
  利用第三方的分享框架(友盟+ ShareSDK 百度社会化分享组件)

iOS自带分享

//导入框架
 Social.framework
//导入头文件
#import 

    //1.判断分享平台是否可用
    if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeSinaWeibo]){
        NSLog(@"请到系统设置中添加账号和密码");
    }
    //2.创建分享控制器
    //ServiceType:分享的平台
    SLComposeViewController *composeVC = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeSinaWeibo];
    //设置预设的文字
    [composeVC setInitialText:@"预设文字:"];
    //预设的图片
    [composeVC addImage:[UIImage imageNamed:@"图片"]];
    //预设网址
    [composeVC addURL:[NSURL URLWithString:@"http://www.baidu.com"]];
    //3.弹出控制器
    [self presentViewController:composeVC animated:YES completion:nil];

应用间跳转

if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"change://"]]){
                NSLog(@"不能打开对应的app");
    }

跳转到指定页面

 if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"change://page1"]]){
        NSLog(@"不能打开对应的app");
    }

-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options{
    NSLog(@"%@",url);
    //转换成字符串
    NSString *urlstr = url.absoluteString;
    //获取//范围
    NSRange range =[urlstr rangeOfString:@"//"];
    //获取跳转的字符串
    NSString *str = [urlstr substringFromIndex:range.location + range.length];
    //根据截取的字符串,跳转不同的界面

    //获取跟控制器
    UINavigationController *nav = (UINavigationController *)self.window.rootViewController;
    //跳转回跟控制器
    [nav popToRootViewControllerAnimated:NO];
    //获取控制器
    ViewController *vc = nav.childViewControllers[0];
    if(str = @"page1"){
        //跳转控制器
        [vc performSegueWithIdentifier:@"page1" sender:nil];
    }
    return YES;
}

回跳

//跳入的时候,传入自己的scheme
- (IBAction)page1:(id)sender {
    
    NSString *header = @"change://page1";
    //1.获取协议头
    NSDictionary *info = [NSBundle mainBundle].infoDictionary;
    NSLog(@"%@",info);
    NSArray *urlTypes = info[@"CFBundleURLTypes"];
    NSDictionary *typesInfo = urlTypes[0];
    NSArray *schemes = typesInfo[@"CFBundleURLSchemes"];
    NSString *scheme = schemes[0];
    
    NSString *urlstr = [NSString stringWithFormat:@"%@?%@",header,scheme];

    if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlstr]]){
                NSLog(@"不能打开对应的app");
    }
}

//跳转到指定页面,并截取跳转过来页面的sheme数据
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options{
    NSLog(@"%@",url);
    //转换成字符串
    NSString *urlstr = url.absoluteString;
    //获取//范围
    NSRange range =[urlstr rangeOfString:@"//"];
    //获取跳转的字符串
    NSString *str = [urlstr substringFromIndex:range.location + range.length];
    //根据截取的字符串,跳转不同的界面
    self.str = str;
    //获取跟控制器
    UINavigationController *nav = (UINavigationController *)self.window.rootViewController;
    //跳转回跟控制器
    [nav popToRootViewControllerAnimated:NO];
    //获取控制器
    ViewController *vc = nav.childViewControllers[0];
    if([str containsString:@"page1"]){
        [vc performSegueWithIdentifier:@"page1" sender:nil];
    }else if([str containsString:@"page2"]){
        [vc performSegueWithIdentifier:@"page2" sender:nil];
    }
    //跳转控制器
    
    return YES;
}

//从scheme中拿到回调页面的scheme,完成页面跳转
- (IBAction)back:(id)sender {
    AppDelegate *d = (AppDelegate *)[UIApplication sharedApplication].delegate;
    NSString *strurl = d.str;
    NSRange range = [strurl rangeOfString:@"?"];
    NSString *str = [strurl substringFromIndex:range.location + range.length];
    if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:[str stringByAppendingString:@"://"]]]){
        NSLog(@"不能打开对应的app");
    }
