无法将 ToFile 写入 NSSearchPathForDirectoriesInDomains(.CachesDirectory、.UserDomainMask、true)
Cannot writeToFile to NSSearchPathForDirectoriesInDomains(.CachesDirectory,.UserDomainMask, true)
我想保存到文件 NSSearchPathForDirectoriesInDomains(.CachesDirectory,.UserDomainMask, true)。我写了如下代码,但是它不能将文件保存在缓存目录中,它的成功变成了错误。你能告诉我如何解决这个问题吗?谢谢你的好意。
let paths2 = NSSearchPathForDirectoriesInDomains(
.CachesDirectory,
.UserDomainMask, true)
let cachesPath: AnyObject = paths2[0]
var user:NSDictionary = [
"Name": "Tom",
"Address": "Tokyo",
]
let success = user.writeToFile(cachesPath as! String, atomically: true)
if success {
println("save sucess")
}
您正在尝试使用 Caches
目录的路径保存文件。您只能将文件写入文件路径。要创建文件路径,请将文件名附加到要保存它的目录中,如下所示:
let paths2 = NSSearchPathForDirectoriesInDomains(
.CachesDirectory,
.UserDomainMask, true)
let cachesPath: AnyObject = paths2[0]
var user:NSDictionary = [
"Name": "Tom",
"Address": "Tokyo",
]
let filePath = cachesPath.stringByAppendingPathComponent("CachedUser")
let success = user.writeToFile(filePath, atomically: true)
if success {
println("save sucess")
}
