iOS json字符串转化为NSArray(解析)

URL：http://www.12beli.com/App/Index/Category?pid=0 往服务器发数据返回的是数组

服务器返回数据如下：

dict-123--{

CategoryName = Komputer;

ID = 4;

ParentID = 0;

child = "[{\"ID\":16,\"CategoryName\":\"Laptop\",\"ParentID\":4},{\"ID\":15,\"CategoryName\":\"Desktop\",\"ParentID\":4},{\"ID\":14,\"CategoryName\":\"Printer\",\"ParentID\":4},{\"ID\":24,\"CategoryName\":\"Aksesori Komputer\",\"ParentID\":4},{\"ID\":21,\"CategoryName\":\"Proyektor\",\"ParentID\":4},{\"ID\":204,\"CategoryName\":\"Networking\",\"ParentID\":4},{\"ID\":209,\"CategoryName\":\"Lain-Lain\",\"ParentID\":4},{\"ID\":215,\"CategoryName\":\"Hardware\",\"ParentID\":4}]";

如要取child里面的内容需要将json字符串转换，否则按正常取法的话会crash

参考：

NSMutableString *jsonDataString=[NSMutableString string];

[jsonDataString setString:[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"jsonData" ofType:@"txt"] encoding:NSUTF8StringEncoding error:nil]];

NSData *nsData=[jsonDataString dataUsingEncoding:NSUTF8StringEncoding];

parsedArray=[NSJSONSerialization JSONObjectWithData:nsData options:kNilOptions error:nil];

我解析的内容（ASIHTTPRequest）

- (void)requestFinished:(ASIHTTPRequest *)request

{

SBJSON * json = [[SBJSONalloc]init];

_dataArray = [jsonobjectWithString:[requestresponseString]error:nil];

if ([_dataArraycount] !=0) {

for (NSDictionary * dictin_dataArray) {

NSString *str= [dictobjectForKey:@"child"];

NSData *nsData=[strdataUsingEncoding:NSUTF8StringEncoding];

NSArray *childArray=[NSJSONSerializationJSONObjectWithData:nsDataoptions:kNilOptionserror:nil];

if ( childArray !=nil ) {

// for(int i=0;i<[childArray count];i++)

// {

// [childArray objectAtIndex:i];

// }

for (NSDictionary * littleDictin childArray) {

NSString * name = [littleDictobjectForKey:@"CategoryName"];

}
