网络中数据的传输往往是以Json或XML格式进行的,如新浪微博、腾讯微博、人人网等。今天主要介绍一下ios下Json数据的解析。
首先是使用TouchJson进行解析:
TouchJson点击下载
首先导入
将Source文件加下的所以文件导入工程,在合适的位置添加CJSONDeserializer.h头文件。
代码:
NSString *jsonStr = <p class="p1">@"{\"customer\":[{\"name\":\"roamer\",\"ycount\":\"232.4\",\"sumcount\":\"322.3\"},{\"name\":\"<span class="s1">王三</span>\",\"ycount\":\"221.2\",\"sumcount\":\"1123.2\"},{\"name\":\"<span class="s1">李四</span>\",\"ycount\":\"1221.2\",\"sumcount\":\"12123.2\"}]}"<span class="s2">;</span></p>; NSData *jsonData = [jsonStr dataUsingEncoding:NSUTF8StringEncoding]; NSError *error; NSMutableDictionary *root = [[CJSONDeserializer deserializer] deserialize:jsonData error:&error]; NSLog(@"Customers:%@", root); NSMutableArray *customers = [root objectForKey:@"customer"]; NSString *jsonTextStr = @"姓名:\n"; for (NSMutableDictionary *customer in customers) { NSString *name = [customer objectForKey:@"name"]; name = [name stringByAppendingString:@"\n"]; jsonTextStr = [jsonTextStr stringByAppendingString:name]; NSLog(@"customer:%@",[customer objectForKey:@"name"]); }
输出结果:Customers:{ customer = ( { name = roamer; sumcount = "322.3"; ycount = "232.4"; }, { name = "\U738b\U4e09"; sumcount = "1123.2"; ycount = "221.2"; }, { name = "\U674e\U56db"; sumcount = "12123.2"; ycount = "1221.2"; } ); } 2012-06-15 14:08:20.406 TouchJsonTest[1495:f803] customer:roamer 2012-06-15 14:08:20.406 TouchJsonTest[1495:f803] customer:王三 2012-06-15 14:08:20.406 TouchJsonTest[1495:f803] customer:李四
下面使用SBJson

首先导入
将Classes文件加下的所以文件导入工程,在合适的位置添加SBJson.h头文件。
