-canOpenURL: failed for URL: "kindle://home" - error: "This app is not allowed to query for scheme k

iOS 从C APP里启动 D APP 

首先在D APP里设置 URL Schemes 

在info.plist 文件里添加URL Schemes 

URL Types -->item0 --> URL Schemes --> TestD 

 

然后再回到C APP 找到info.plist 文件

添加 LSApplicationQueriesSchemes  --> item0  TestD
D程序

-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation{

    NSString *str=[NSStringstringWithFormat:@"url:%@,source application:%@,params:%@",url,sourceApplication,[urlhost]];

    NSLog(@"%@",str);

    UIAlertView * alert = [[UIAlertViewalloc]initWithTitle:@"提示"message:[url
host]delegate:selfcancelButtonTitle:@"OK"otherButtonTitles:nil,nil];

    

    [alert show];

    

    return
YES;//是否打开

}

C程序

NSString *url=@"TestD://MyNameIsHanMeiMei";

    [self openUrl:url];

-(void)openUrl:(NSString *)urlStr{

   
//注意url中包含协议名称，iOS根据协议确定调用哪个应用，例如发送邮件是“sms://”其中“//”可以省略写成“sms:”(其他协议也是如此)

    NSURL *url=[NSURLURLWithString:urlStr];

    UIApplication *application=[UIApplicationsharedApplication];

    if(![application
canOpenURL:url]){

        NSLog(@"无法打开\"%@\"，请确保此应用已经正确安装.",url);

        return;

    }

    [[UIApplicationsharedApplication]
openURL:url];

}
