在iphone中使用url编码使用%2b之前添加+

Question

我有一个应用程序,在按钮单击我传递我的服务器api方法,它调用JSON post方法并将数据保存到服务器数据库.这里我将我的手机号码和紧急号码保存到服务器数据库.我的手机号码是字符串格式.在我的手机号码字符串变量中,我的手机号码正在保存,格式为"+ 90-9491491411".我输入+然后编码然后 - 然后编号但是当我发送到服务器数据库时我正在删除 - 并且发送no到数据库,但问题是我的服务器数据库+移动没有进入我正在输入.可能是什么问题.我正在使用POST方法发送请求.这是我的代码

-(void)sendRequest
{

    NSString *newstring = txtMobile.text;
    mobileValue = [newstring stringByReplacingOccurrencesOfString:@"-" withString:@""];
    NSLog(@"%@",mobileValue);



    NSString *newString1 = txtemergencyprovider.text;
    emergencyNumber = [newString1 stringByReplacingOccurrencesOfString:@"-" withString:@""];


        NSLog(@"%@",emergencyNumber);
    if ([txtEmail.text  isEqualToString:@""])
    {
        post = [NSString stringWithFormat:@"CommandType=new&ApplicationType=%d&FullName=%@&Mobile=%@&EmergencymobileNumber=%@&Latitude=%f&Longitude=%f&City=%@&MobileModel=Apple",applicationtype,txtFullname.text,mobileValue,emergencyNumber,latitude,longitude,txtCity.text];
        NSLog(@"%@",post);
    }
    else {
        post = [NSString stringWithFormat:@"CommandType=new&ApplicationType=%d&FullName=%@&Mobile=%@&EmergencymobileNumber=%@&Latitude=%f&Longitude=%f&City=%@&EmailAddress=%@&MobileModel=Apple",applicationtype,txtFullname.text,mobileValue,emergencyNumber,latitude,longitude,txtCity.text,txtEmail.text];
        NSLog(@"%@",post);
    }


    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; 
    NSLog(@"%@",postLength);
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:@"http://myapi?RequestType=NEW"]]; 
    [request setHTTPMethod:@"POST"]; 
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
    [request setHTTPBody:postData];

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    if (theConnection) {
        webData = [[NSMutableData data] retain];
        NSLog(@"%@",webData);
    }
    else 
    {

    }

}

//在我的手机号码和紧急号码变量中,我的号码格式为"+91986444711",但是当在服务器数据库中输入值时,将被删除.可能是概率.

不幸的是,NSString's -stringByAddingPercentEscapesUsingEncoding:不会将plus(+)符号转换为,%2B因为加号是一个有效的URL字符,用于分隔查询参数.这通常意味着Web服务器将其转换为空格字符.

替换加号的最简单方法是使用NSString's stringByReplacingOccurrencesOfString:withString:替换+with %2B.例如:

mobileValue = [mobileValue stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"];
