UPDATE-8/31/12-所以现在我需要通过基于“isReservable”= 1 的字典数组，然后显示“开始”。我只是想获取每个字典数组的内容，我可以从那里开始(现在)。以下是我尝试过的。感谢大家的帮助，我每天都在学习更多知识。

这是我目前所拥有的
- (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-这就是我让它工作的方式:
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"]);
}
}
现在我只需要把它改成 if "isReservable"= true then display "begin"
Best Answer-推荐答案
看起来 myslots 是一个 NSDictionary，而不是一个 NSArray ...要遍历它的所有键，更改
for (NSDictionary *slots in myslots) {
// code
}
为
for (NSString *slotKey in myslots.allKeys) {
NSDictionary *slot = [myslots valueForKey:slotKey];
// code
}
