,可以使用Property List Serialization来实现。Property List Serialization是iOS和macOS中用于处理plist文件的API。
保存数字到plist文件:
示例代码:
let number: Int = 42
let dict: NSDictionary = ["number": NSNumber(value: number)]
if let plistData = try? PropertyListSerialization.data(fromPropertyList: dict, format: .xml, options: 0) {
if let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.appendingPathComponent("Numbers.plist") {
do {
try plistData.write(to: fileURL)
print("Number saved to plist file.")
} catch {
print("Error saving plist file: \(error)")
}
}
}
加载数字从plist文件:
示例代码:
if let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first?.appendingPathComponent("Numbers.plist") {
if let plistData = try? Data(contentsOf: fileURL),
let dict = try? PropertyListSerialization.propertyList(from: plistData, options: [], format: nil) as? NSDictionary,
let number = dict["number"] as? NSNumber {
let loadedNumber = number.intValue
print("Loaded number from plist file: \(loadedNumber)")
}
}
这样,你就可以通过plist文件保存和加载数字了。
