JSON_CATEGORY_DATA_URL_STRING我的Feed网址在哪里,返回正常:

[
    {
        "group":"For Sale",
        "code":"SSSS"
    },
    {
        "group":"For Sale",
        "category":"Wanted",
        "code":"SWNT"
    }
]

我似乎无法从以下代码中获得一个好的NSDictionary(或NSArray):

+ (NSDictionary *)downloadJSON
{

NSDictionary *json_string;
NSString *dataURL = [NSString stringWithFormat:@"%@", JSON_CATEGORY_DATA_URL_STRING];
NSLog(@"%@",dataURL);
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:dataURL]];    
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

json_string = [[[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]autorelease];
NSDictionary *json_dict = (NSDictionary *)json_string;
NSLog(@"json_dict\n%@",json_dict);
    NSLog(@"json_string\n%@",json_string);

return json_string;
}

我已经阅读了很多这方面的帖子,但我没有得到它.

我有来自Web服务器的JSON响应,如下所示:

{"success":true, "token":"123456"}

我想在if语句中使用它,并将其与"YES"进行比较.

但是,这样做不起作用:

NSDictionary *response = [response JSONValue]; // the JSON value from webservice response, converted to NSDictionary

if ([response objectForKey:@"success"]){} // does not work
if ([response objectForKey:@"success"] == YES){} // does not work
if ([[response objectForKey:@"success"] integerValue] == YES) {} // does not work...erroneous probably

我该如何解决这个问题？布尔中的类型转换也会产生警告

在我的iPhone应用程序中,我有一个自定义对象列表.我需要从它们创建一个json字符串.我如何用SBJSON或iPhone sdk实现这个？

 NSArray* eventsForUpload = [app.dataService.coreDataHelper fetchInstancesOf:@"Event" where:@"isForUpload" is:[NSNumber numberWithBool:YES]];
    SBJsonWriter *writer = [[SBJsonWriter alloc] init];  
    NSString *actionLinksStr = [writer stringWithObject:eventsForUpload];

我得到空的结果.

请告诉我如何解决这个问题？

我正在处理XCode的奇怪行为:

dyld: Library not loaded: /Library/Frameworks/SBJson.framework/Versions/A/SBJson

基本上它忽略了实际的my Runpath Search Path(LD_RUNPATH_SEARCH_PATHS)配置@loader_path/../Frameworks.

我暂时无法加载任何嵌入式框架:/

otool 说

PS如果您想知道我是否将副本添加到框架构建阶段,答案是肯定的.

我刚刚克隆了SBJson框架的git存储库,并将源代码导入到我的应用程序中.跑了一个静态内存探查器,并从我看到的结果有点害怕.看图

这怎么可能？我怀疑这个知名图书馆的开发者没有看到这个？事实上,如果运行内存配置文件,它会显示此库中的内存泄漏.

有任何想法吗？谢谢

我收到此错误:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_ASIHTTPRequest", referenced from:
      objc-class-ref in FirstViewController.o
  "_OBJC_CLASS_$_SBJsonParser", referenced from:
      objc-class-ref in FirstViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

注意我添加了框架核心图形,系统配置,移动核心服务,libz.dylib,libz.1.2.5.dylib,CF网络,UI工具包和基础.我搜索了所有论坛,花了差不多4天但却找不到原因.

当我评论我的ASIHTTPRequest和SBJSON代码行时,它工作正常.我添加了ASIHTTPRequest和SBJSON的所有类,并检查了三次.有谁能建议我做错了什么？

我从Web服务中获取了一个较大的JSON字符串（11MB）。当我使用JSONKit解析数据时，我的应用程序达到70MB，收到内存警告，并且应用程序崩溃。

如何解析此数据？

我目前在我的项目中有ShareKit,它被编译为静态库.它已得到妥善实施.我还通过将他们的框架添加到我的项目中来实现亚马逊的AWS SDK.

似乎重复的符号来自亚马逊的AWS SDK文件"AWSIOSSDK".这就是它的样子:

该文件与ShareKit的文件libShareKit.a发生冲突.这是该文件的样子:

无论如何,这些文件都是我以前从未见过的文件.似乎有些JSON文件在它们之间发生冲突.

我已经查看了其他SO问题,并且他们说要使用已编译的源代码执行某些操作,但这些文件都不在任何库的编译源中.

这是Xcode给出的确切错误:

ld: duplicate symbol _OBJC_CLASS_$_SBJsonParser

无论如何,有没有人有任何想法我应该做什么？除非我解决这个问题,否则我的应用程序无法编译

谢谢!

我正在使用SBJson解析器开始一个新项目,人们似乎建议将其作为新的iOS项目的互联网上最好的.我有一个非常strage的问题是,目前的方法斯蒂格Brautaset声称你可以在使用当前版本(3.1) ,似乎过时了,或者至少那是什么我的编译器说.我似乎无法上班:

NSDictionary *dict = [responseString JSONValue];

这似乎是最新的方式或:

NSDictionary *dict = [parser objectWithString:responseString error:&error];

解析器是一个sbjson解析器.XCode突出显示了这两个函数并告诉我它们已被弃用.

我在这做错了什么？
