我有一个这种格式的字符串：- { panel : {start : [{"element_id" : 0, "element_name" :0, "element_image" : 0, "element_desc" : 0, "element_dob" : 0, "awards" :0},]}我该如何解析这个字符串。请帮助我克服这个问题。我试过 SBJSon - 代码： -

NSLog(@"response string before = %@", responseStr);
NSData *fileData = [NSData dataWithContentsOfFile:responseStr];
NSString *responseString = [[NSString alloc] initWithData:fileData encoding:NSUTF8StringEncoding];
NSLog(@"response string after = %@", responseString);
NSError *jsonError = nil;
NSDictionary *feed = nil;
    SBJsonParser *json = [[SBJsonParser new] autorelease];
feed = [json objectWithString:responseString error:&jsonError];
NSLog(@"feed = %@", feed);
if ([jsonError code]==0) {
    // get the array of "results" from the feed and cast to NSArray
    NSMutableArray *localObjects = [[[NSMutableArray alloc] init] autorelease];
    NSArray *results= (NSArray *)[feed valueForKey:@"start"];

    // loop over all the results objects and print their names
    int ndx;

    for (ndx = 0; ndx < results.count; ndx++) 
    {
        [localObjects addObject:(NSDictionary *)[results objectAtIndex:ndx]];
    }
    NSLog(@"local objects = %@", localObjects);
}

试试下面的...

    SBJSON *json = [[SBJSON new] autorelease];  
    NSDictionary *dictResponse = (NSDictionary*) [json objectWithString:sitesResponse error:nil];

您可以使用正则表达式 ( wiki )。从以下来源获取：RegexKit，添加到链接器标志“-fopenmp”并在 NSString 消息“stringByMatching”中使用。

例如，如果你想取“element_name”：

NSString* str = [your_string stringByMatching:@"element_name\".*:(.*?)," capture: 1L];
