How do I load a text file into an array with swift?
答
以下内容：
func arrayFromContentsOfFileWithName(fileName: String) -> [String]? {
guard let path = NSBundle.mainBundle().pathForResource(fileName, ofType: "txt") else {
return nil
}
do {
let content = try String(contentsOfFile:path, encoding: NSUTF8StringEncoding)
return content.componentsSeparatedByString("\n")
} catch _ as NSError {
return nil
}
}
此方法假定相关文件位于您的应用包中。
This approach assumes the file in question is located in your app bundle.
