字典或帶有數組的字典的Arrary？
[英]Arrary of Dictionaries or Dictionary with arrays?
問題描述
這是我的php頁面中的json。 這是字典的Arrary還是只是一個帶有鍵的字典，並且這些鍵在其中？ 我認為這是第二種選擇，但我不確定，因為我遇到了一些沖突的選擇。 一旦在xcode調試器中顯示，結構也會改變嗎？

5 個解決方案
解決方案1
2 已采納 2012-08-31 14:20:53
在這里看看： http : //www.json.org/
基本上，您有一個詞典slots ，其中有多個對象。 鍵看起來像是這樣的東西2012-08-31 00:00:00 America/Los_Angeles 。 這些鍵包含字典數組。
解決方案2
1 2012-08-31 14:22:11
您可以做的最好的事情就是嘗試一下！ 您所浪費的時間將少於在這里詢問的時間！ 無論如何，您有：
- dictionary, with a "slot" key that has an associated value:
- dictionary, with a "2012-08-31 00:00:00 America/Los_Angeles" key that that has an associated value:
- array, containing objects:
- dictionary1
- dictionary2
- ....
因此，例如，訪問第二個元素的isPending屬性：
[[[[dict objectForKey:@"slot"] objectForKey:@"2012-08-31 00:00:00 America/Los_Angeles"] objectAtIndex:1] valueForKey:@"isPending"];
解決方案3

字典周圍的[和]似乎暗示它是一系列字典。
或者更確切地說，是Dictionary內部的Dictionary的Array 。 第一段僅涉及最內部的結構。

您可能會發現在此處使用NSLog進行調試很有用。
假設您想確定您的類是NSArray，Dictionary還是其他類。 傳遞JSON數據后。 要查看返回的內容，只需注銷即可。
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([jsonData Class]);
這將告訴您json數據是什么類。
您還可以使用相同的方法來確定下一個項目是字典還是這樣的數組
[NSLog(@" JSON data is kind of class %@", [NSStringFromClass([[jsonData objectAtIndex:i]Class]);
但是純粹從觀察的角度來看，我會說您有一本字典詞典

這是我的方法。
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"]);
}
}
