downloadedURLArray.append(urlString)
UserDefaults.st
我一直在与数组挣扎;我试图将一些数组保存到用户默认值中。我的数组是String,Double和UIImageView类型。我宣布他们像: var nameHospital = [String]()
var distanceBetweenLocations = [Double]()
var images = [UIImage]() // <-- Haven't tried with this y
我有一个用户默认布尔音乐播放。 当首次推出,我尝试将布尔设置为true,像这样... if launchedBefore {
// Do nothing.
} else {
UserDefaults.standard.set(true, forKey: "musicOn")
print("music is \(musicOn)")

如何修复异常: [User Defaults] Attempt to set a non-property-list object {
4 = 5;
} as an NSUserDefaults/CFPreferences value for key MyKey
通过执行下面的代码抛出(SWIFT 3) let ns = NSDictionary(dictionary: [4: 5])
