ios - 将字符串条目从 Swift iOS 中的 UITextField 保存到 plist

转载作者：行者123 更新时间：2023-11-30 13:22:06

我想知道如何获取输入到 UItextField 中的值并将其保存到 Plist 文件 strIng 条目中，其中键为“customText”。

有人知道我在这里做错了什么吗？

这是我当前的 View Controller :

最佳答案

您好，我认为您需要将您的 Card 类转换为 Dictionary 然后您需要将此字典保存到 plist，为此您必须放置此方法在你的卡片类别中。请注意，如果您使用某个类作为此 Card 类的属性，则必须将此类也转换为字典

func toDictionary() -> NSDictionary
    {
        let returnDict = NSMutableDictionary();
        returnDic.setObject(title, forKey: "title");
        returnDic.setObject(name, forKey: "name");
        //**PUT ALL YOUR ATTRIBUTES IN THE DICTIONARY//

        return returnDict;
    }

然后你需要循环你的卡片并将你的字典放入一个数组中，然后你必须将该数组传递给这个方法

static func saveArray(array:NSArray,filename:String) ->Bool
{
    let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true);
    let docsDirectory = paths[0];
    let path = docsDirectory + "/" + filename;
    return array.writeToFile(path, atomically: true);
}
