传递URL到Three20 TTURLMap [英] Passing url to Three20 TTURLMap

问题描述

我正在尝试将一个URL作为参数传递给TTURLMap，如下所示：


[map from @ tt：// person /（initWithURL :)toViewController：
[PersonViewController class]];


然后我有一个TTStyledTableItemCell，其链接呈现如下：

< a href =tt：// person / http：//persons.url.com/blah>个人名称< / a> p>

但是当我点击这些链接时，链接不会调用PersonViewConroller类中的initWithURL：
方法。我已经验证的东西是
通过传递一个简单的字符串正确连接。我相信这个
不工作，因为解析器认为URL是
TTURLMap url映射的一部分。有没有办法逃避该人的饲料网址
（我需要使用的休息服务来提取信息）？

提前多谢。

解决方案

我认为TTURLMap唯一出现的角色是 / 字符，所以以下为我做的伎俩。只要打电话给Mike，在你的初始化函数中进入和退出

  +（NSString *）encodeTtUrl：（NSString * ）str {
 NSMutableString * temp = [NSMutableString stringWithString：str]; 
 [temp replaceOccurrencesOfString：@/withString：@__options：NSLiteralSearch range：NSMakeRange（0，[temp length]）]; 
 return [NSString stringWithString：temp]; 
} 
 
 +（NSString *）decodeTtUrl：（NSString *）str {
 NSMutableString * temp = [NSMutableString stringWithString：str]; 
 [temp replaceOccurrencesOfString：@__withString：@/options：NSLiteralSearch range：NSMakeRange（0，[temp length]）]; 
 return [NSString stringWithString：temp]; 
} 
  

I am trying to pass in a URL as a parameter to a TTURLMap like this:

[map from@"tt://person/(initWithURL:)" toViewController: [PersonViewController class]];

I then have a TTStyledTableItemCell with links that render like this:

<a href="tt://person/http://persons.url.com/blah">Person name</a>

but when I click on these links the link doesn't call the initWithURL: method in the PersonViewConroller class. I've verified things are wired up correctly by passing in a simple string. I believe this isn't working because the parser thinks the URL is part of the TTURLMap url mapping. Is there a way to escape the person's feed url (its a rest service that i need to use to pull info in)?

many thanks in advance.

解决方案

I think the only character that TTURLMap trips up on is the / character, so the following did the trick for me. Just call these as Mike suggests on the way in and out of your init function

+ (NSString *)encodeTtUrl:(NSString *)str {
    NSMutableString *temp = [NSMutableString stringWithString:str];
    [temp replaceOccurrencesOfString:@"/" withString:@"__" options:NSLiteralSearch range:NSMakeRange(0, [temp length])];
    return [NSString stringWithString:temp];
}

+ (NSString *)decodeTtUrl:(NSString *)str {
    NSMutableString *temp = [NSMutableString stringWithString:str];
    [temp replaceOccurrencesOfString:@"__" withString:@"/" options:NSLiteralSearch range:NSMakeRange(0, [temp length])];
    return [NSString stringWithString:temp];
}
