swift - 使用 Swift 在字符串中插入应用程序版本？

Question

这个问题已经有答案了:

iOS app, programmatically get build version (7 个回答)

已关闭 6 年前。

我有一些 Swift 代码，我想插入应用程序的属性(版本)。这可能吗？

var parameters: [String : AnyObject] = [
    "offerSef" : url,
    "userGuid" : user.userGuid,
    "bottlesQty" : quantityIndex + 1,
    "appId" : "iOS" + /* WANT TO INSERT APP VERSION HERE */,
    "creditCardId" : payment.paymentID,
    "billingAddressId" : payment.billingAddressId,
    ]

注意:这不是 iOS app, programmatically get build version 的重复项因为我的问题是如何使用 Swift(而不是 Objective-C)以正确的方式做到这一点

Answer 1

这是我从这里的另一个问题中拼凑出来的答案，但我也想知道是否有人有评论或知道更好/更干净的方法。

    //First get the nsObject by defining as an optional anyObject
    if let nsObject: AnyObject? = NSBundle.mainBundle().infoDictionary["CFBundleShortVersionString"] {

        //Then just cast the object as a String, but be careful, you may want to double check for nil
        if let version = nsObject as String {
            appId = appId + "-" + version
        }
    }

    var parameters: [String : AnyObject] = [
        "offerSef" : url,
        "userGuid" : user.userGuid,
        "bottlesQty" : quantityIndex + 1,
        "appId" : appId,
        "isMobile" : true,
        "creditCardId" : payment.paymentID,
        "billingAddressId" : payment.billingAddressId,
    ]
