NSData *webData = [ @"{\"\":
{\"name\": \"Jerry\",\"age\": \"12\"},
\"2\":
{\"name\": \"Bob\",\"age\": \"16\"} }" dataUsingEncoding:NSUTF8StringEncoding ];
NSError *error;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options: 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: {
= {
age = ;
name = Jerry;
};
= {
age = ;
name = Bob;
};
}
如果你的jsonString是下面格式的话:
[ {"id":,"title":"销售员","number":,"education":,"money":,"years":,"companyname":"腾讯网络技术有限公司","company":},
{"id":,"title":"程序员","number":,"education":,"money":,"years":,"companyname":"腾讯网络技术有限公司","company":} ]
那调用[NSJSONSerialization JSONObjectWithData:webData options:0 error:&error]返回的就是NSArray, NSArray里面是2个NSDictionary。
