NSData *webData = [ @"{\"1\":
{\"name\": \"Jerry\",\"age\": \"12\"},
\"2\":
{\"name\": \"Bob\",\"age\": \"16\"} }" dataUsingEncoding:NSUTF8StringEncoding ]; NSError *error; NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
/*
NSJSONReadingMutableContainers = (1UL << 0), // 创建可变的数组或字典来接收 0
NSJSONReadingMutableLeaves = (1UL << 1), // 指定在JSON对象可变字符串被创建为NSMutableString的实例 1
NSJSONReadingAllowFragments = (1UL << 2) // 指定解析器应该允许不属于的NSArray或NSDictionary中的实例顶层对象 2
*/
NSLog(@"JSON DIct: %@", jsonDict); 输出如下: JSON DIct: { 1 = { age = 12; name = Jerry; }; 2 = { age = 16; name = Bob; }; }
如果你的jsonString是下面格式的话:
[ {"id":5,"title":"销售员","number":2,"education":1,"money":1,"years":1,"companyname":"腾讯网络技术有限公司","company":1},
{"id":13,"title":"程序员","number":2,"education":1,"money":1,"years":1,"companyname":"腾讯网络技术有限公司","company":1} ]
那调用[NSJSONSerialization JSONObjectWithData:webData options:0 error:&error]返回的就是NSArray, NSArray里面是2个NSDictionary。
