從NSArray中刪除重複的鍵值

     ImagePath = "<null>"; 
     ImageTypeId = 6; 
    }, 
     { 
     ImageName = "http://192.168.1.8:9701/190214/190214_image0_08_13_2016_06_15_21.jpg"; 
     ImagePath = "<null>"; 
     ImageTypeId = 0; 
    }, 
     { 
     ImageName = "http://192.168.1.8:9701/190214/190214_image1_08_13_2016_07_19_57.jpg"; 
     ImagePath = "<null>"; 
     ImageTypeId = 1; 
    }, 
     { 
     ImageName = "http://192.168.1.8:9701/190214/190214_image1_08_13_2016_07_19_57.jpg"; 
     ImagePath = "<null>"; 
     ImageTypeId = 1; 
    } 
)

我想刪除所有對象的鍵是重複的 For Ex。 ImageTypeId = 1;對象是兩次，所以想要刪除1個對象，並且只有一個ImageTypeId = 1的對象;從NSArray中刪除重複的鍵值

我需要獨特的ImageTypeId = 1值 – ZetrixWeb

您是否需要保存順序？ –

不，不需要重複的ImageTypeId，它應該是唯一的 – ZetrixWeb

創建字典保持值：

var dict = [NSObject: AnyObject]()

每個項目添加到使用typeid作爲密鑰詞典：

for item in arr { 
    guard let typeid = item["ImageTypeId"] as? NSObject else { continue } 
    dict[typeid] = item 
}

與字典中的值創建一個數組：

let newarray = Array(dict.values)
