檢索數組排序問題你好我想也一定String添加到一個Array,然後存儲它的值與UserDefaults,這裏是我的代碼: func addStored(urlString:String) {
//Add URL to array and save it
downloadedURLArray.append(urlString)
UserDefaults.st
我一直在與數組掙扎;我試圖將一些數組保存到用戶默認值中。我的數組是String,Double和UIImageView類型。我宣佈他們像: var nameHospital = [String]()
var distanceBetweenLocations = [Double]()
var images = [UIImage]() // <-- Haven't tried with this y
我有一個用戶默認布爾音樂播放。 當首次推出,我嘗試將布爾設置爲true,像這樣... if launchedBefore {
// Do nothing.
} else {
UserDefaults.standard.set(true, forKey: "musicOn")
print("music is \(musicOn)")

如何修復異常: [User Defaults] Attempt to set a non-property-list object {
4 = 5;
} as an NSUserDefaults/CFPreferences value for key MyKey
通過執行下面的代碼拋出(SWIFT 3) let ns = NSDictionary(dictionary: [4: 5])
