问题描述
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。感谢每个人的帮助，我每天都在学习。
UPDATE-8/31/12- So now I would need to go through the Array of Dictionaries based on "isReservable" = 1 and then display the "begin". I am just trying to get the contents of the array of each dictionary and I can go from there (for now). Below is what I have tried. Thanks to everyone for the help I am learning more everyday.

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 - 这就是我开始工作的方式：
Update- This is how I am getting it to work:
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"]);
}
}
现在我只需更改它就可以说 isReservable= true然后显示开始
Now I just need to change it to say if "isReservable" = true then display "begin"
推荐答案
看起来myslots是一个NSDictionary，而不是NSArray ...迭代通过它的所有键，更改
it looks like myslots is an NSDictionary, not an NSArray ... to iterate through all it's keys, change
for (NSDictionary *slots in myslots) {
// code
}
for
for (NSString *slotKey in myslots.allKeys) {
NSDictionary *slot = [myslots valueForKey:slotKey];
// code
}
