如何在NSString中为Facebook stream.publish插入换行符

问题描述

我看到Facebook上的某些应用程序可以将带有换行符的墙消息发布到用户墙上，像这样:

I saw some applications on Facebook can post to user wall messages with linebreaks - like that:

1. blablabla
2. blablabla等等

1. blablabla
2. blablablaetc

我的代码将此文本放在Facebook上-"1. blablabla 2. blablabla等"如何在Facebook的stream.publish的描述部分插入换行符

My code put this text on Facebook - "1. blablabla 2. blablabla etc" How can I insert linebreak in description part of stream.publish in Facebook

\ n-不起作用

我的代码是

- (void)publishTopToStream{

NSMutableString *topTenArrayString=[[NSMutableString alloc] initWithFormat:@""];

for (int i=0; i<7; i++) {
    NSString *tempString = [[NSString alloc] initWithFormat:@"%d. %@\n ",i+1,[[topTenArray objectAtIndex:i]  personName]];
    [topTenArrayString appendString:tempString];    
    [tempString release];
}

SBJSON *jsonWriter = [[SBJSON new] autorelease];

NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                            @"Top 7 friends", @"name",
                            @"Top 7 friends", @"caption",
                            topTenArrayString, @"description",
                            @"http://www.qqq.net/", @"href",
                            nil];
NSString *attachmentStr = [jsonWriter stringWithObject:attachment];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               kAppId, @"api_key",
                               @"Share on Facebook",  @"user_message_prompt",
                               attachmentStr, @"attachment",
                               nil];

[_facebook dialog: @"stream.publish"
        andParams: params
      andDelegate:self];}

推荐答案

我使用属性，例如:

attachment = { 
            name: Super Application Posr
            href: 'http://apps.facebook.com/superapplication/',
            caption: 'blahh blahh',
            description: 'Here is a list of the top Smelly people in the world' ,
            properties: {
                    1: "Mr Moo",
                    2: "Mrs Moo",
                    3: "Mr Sheep",
                    4: "me"
                    }
              }
