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。
jsonString转NSDictionary
