Ios 筛选Coredata类型的数组

我的tableview单元格中有一个字符串。现在我想检查该字符串是否在特定数组中。如果该数组有字符串，我想从该数组中删除该字符串。这就是我所尝试的

同样在下面，favMessages是一个名为

FavoritedMessages

var textInCell = cell.historyTextLabel.text

for k in favMessages {
    if let thefavData = k.value(forKey: "favData") as? String {                  
        if sdf == thefavData {
             favMessages = favMessages.filter{$0 != textInCell} // HERE ERROR IS THROWN 'Binary operator '!=' cannot be applied to operands of type 'FavoritedMessages' and 'String?''
        }
    }
}

我如何解决我无法解决的问题…

你可以这样做

favMessages = favMessages.filter({$0["Your key name of database"] as! String != "string to be compared"})

就你而言

favMessages = favMessages.filter({$0["favData"] as! String != textInCell})

希望这对您有帮助

您有一个带字符串的数组：

var strings = ["a", "b", "c", "d"]

用于删除的元素：

var firstElement = "a"
var secondElement = "e"

print("Before removing: ", strings)
//Before removing:  ["a", "b", "c", "d"]

[firstElement, secondElement].forEach {
    if let index = strings.index(of: $0) {
        strings.remove(at: index)
    }
}

结果:

print("After removing: ", strings)
After removing:  ["b", "c", "d"]

在下面的代码中编写属性名而不是StringValue

favMessages = favMessages.filter{$0.StringValue != textInCell}

在下面的代码中编写属性名而不是StringValue。favMessages=favMessages.filter{$0.StringValue！=textInCell}favMessages数组中存储了哪些对象？你的建议有效吗。你能把它作为一个答案，让我接受吗。。？
