How do I get a plist as a Dictionary in Swift?(如何在 Swift 中将 plist 作为字典?)

问题描述

I am playing around with Apple's new Swift programming language and have some problems...

Currently I'm trying to read a plist file, in Objective-C I would do the following to get the content as a NSDictionary:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Config" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:filePath];

How do I get a plist as a Dictionary in Swift?

I assume I can get the path to the plist with:

let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist")

When this works (If it's correct?): How do I get the content as a Dictionary?

Also a more general question:

Is it OK to use the default NS* classes? I think so...or am I missing something? As far as I know the default framework NS* classes are still valid and alright to use?

解决方案

In swift 3.0 Reading from Plist.

func readPropertyList() {
        var propertyListFormat =  PropertyListSerialization.PropertyListFormat.xml //Format of the Property List.
        var plistData: [String: AnyObject] = [:] //Our data
        let plistPath: String? = Bundle.main.path(forResource: "data", ofType: "plist")! //the path of the data
        let plistXML = FileManager.default.contents(atPath: plistPath!)!
        do {//convert the data to a dictionary and handle errors.
            plistData = try PropertyListSerialization.propertyList(from: plistXML, options: .mutableContainersAndLeaves, format: &propertyListFormat) as! [String:AnyObject]

        } catch {
            print("Error reading plist: (error), format: (propertyListFormat)")
        }
    }
