我有一个JSON字符串,我将其转换为NSDictionary,并且我将关键字“people”的值获取为NSDictionary:
NSDictionary *testDict = [jsonString JSONValue];
NSDictionary *peopleDict = [testDict objectForKey:@"people"];
一个NSLog of peopleDict
NSLog(@"%@", peopleDict);
返回以下内容:
{
0 = {
id = 1;
name = Doe;
date = "Fri Dec 04 13:50:30 +0200 2009";
};
1 = {
id = 20;
name = Mr. T;
date = "Fri Nov 18 17:55:30 +0200 2009";
};
2 = {
id = 100;
name = TestName;
date = "Mon Nov 30 12:00:10 +0200 2009";
};
}
结果的数量,我知道(在这种情况下为3)。 但是我如何访问行0..2和键值? id是一个int值,name为String,date也是String。
有人知道吗?
提前多多感谢&最诚挚的问候。
答案 0 :(得分:7)
for (id key in peopleDict) {
NSLog(@"key: %@, value: %@", key, [peopleDict objectForKey:key]);
}
这是link to NSDictionary reference
