如何在NSDictionary對象數組中找到鍵ios

我有這樣的NSMutableArray。如何在NSDictionary對象數組中找到鍵ios

[ 
{ 
    "Employee": { 
    "EmployeeCode": 17125, 
    "DisplayName": "MI0000026 - ABC", 
    "DisplayName2": "ABC2", 
    "Initials": "W. S. S.", 
    "Surname": "CCC", 
    "FirstName": "ABC", 
    "MiddleName": "CDE", 
    "LastName": "", 
    "FullName": "ABC EMPLOYEE", 

}, 
"LeaveDetail": { 
    "LeaveDetailId": 21, 
    "LeaveEntryCode": 16, 
    "RequestId": 20, 
    "EmployeeCode": 17125, 
    "LeaveYear": 2016, 
    "LeaveTypeCode": 1, 
    "BaseType": "ess", 
    "LeaveDate": "2016-09-05T00:00:00", 
} 
} 
]

這個數組中有幾個對象有這些類型的字典。我想查找此數組中有"LeaveDate": "2016-09-05T00:00:00"的所有對象，此LeaveDate鍵位於LeaveDetail字典中。我怎樣才能找到所有具有LeaveDate作爲對象「2016-09-05T00：00：00」

編輯 NSPredicate *predicate=[NSPredicate predicateWithFormat:@"LeaveDate CONTAINS[cd] %@",dm.strClickedDate];

但是，我沒有得到任何結果。

請幫幫我。由於

這是不一樣的，我有兩種類型的對象,,我已經嘗試過這樣。 NSPredicate * predicate = [NSPredicate predicateWithFormat：@「LeaveDate CONTAINS [cd]％@」，dm.strClickedDate];但我沒有得到任何結果。這就是爲什麼我發佈這 – Irrd

NSDictonary *dict = [yourMutableArray[0]];//get dict in array with index = 0 
NSLog(@"%@",dict); 
//*Log dict will show: 
{ 
    "Employee": { 
    "EmployeeCode": 17125, 
    "DisplayName": "MI0000026 - ABC", 
    "DisplayName2": "ABC2", 
    "Initials": "W. S. S.", 
    "Surname": "CCC", 
    "FirstName": "ABC", 
    "MiddleName": "CDE", 
    "LastName": "", 
    "FullName": "ABC EMPLOYEE", 

}, 
"LeaveDetail": { 
    "LeaveDetailId": 21, 
    "LeaveEntryCode": 16,
