如何使用包含字典数组的键解析Dictionary

UPDATE-8/31 / 12-所以现在我需要根据“isReservable”= 1来浏览字典数组，然后显示“开始”。 我只是想获取每个字典的数组内容，我可以从那里（现在）。 以下是我的尝试。 感谢大家的帮助，我每天都在学习。

这是我到目前为止所拥有的

 - (void)fetchedData:(NSData *)responseData { //parse out the json data NSError* error; //NSLog(@"string is %@", responseData); NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error]; NSDictionary* myslots =[json objectForKey:@"slots"]; NSLog(@"allslots: %@", myslots); //for (NSString *slotKey in myslots.allKeys) { //NSDictionary *slot = [myslots valueForKey:slotKey]; //NSLog(@"These are all the keys: %@", slotKey); NSArray *keys = [myslots allKeys]; 

更新 – 这是我如何让它工作：

 for (NSString *slotKey in myslots.allKeys) { NSDictionary *slot = [myslots valueForKey:slotKey]; NSArray *tests = [myslots objectForKey:slotKey]; for (NSDictionary *myDict in tests){ NSLog(@"%@", [myDict objectForKey:@"begin"]); } } 

现在我只需要更改它以说“isReservable”= true然后显示“开始”

Answer 1

它看起来像myslots是一个NSDictionary，而不是NSArray …迭代它的所有键，改变

 for (NSDictionary *slots in myslots) { // code } 

对于

 for (NSString *slotKey in myslots.allKeys) { NSDictionary *slot = [myslots valueForKey:slotKey]; // code } 

Answer 2

myslots是一本字典。 似乎第一个键“2012-08-30 00:00:00 America / Los_Angeles”是与您正在寻找的arrays相关联的键。 我建议重新构建数据，使其具有实际的静态键作为访问字典内值的键。
