如何在代碼中獲取我的iOS項目的當前版本？

Question

我希望能夠將我的iOS項目/應用程序的當前版本作爲NSString對象獲取，而無需在某處某個文件中定義常量。我不想在兩個地方更改我的版本值。

當我在項目目標摘要中碰撞我的版本時，需要更新該值。

Answer 1

你可以得到的版本號和編號如下：

let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String 
let build = Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String 

或在Objective-C

NSString * version = [[NSBundle mainBundle] objectForInfoDictionaryKey: @"CFBundleShortVersionString"]; 
NSString * build = [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString *)kCFBundleVersionKey]; 

我有一個類別上UIApplication以下方法：

extension UIApplication { 

    class func appVersion() -> String { 
     return Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String 
    } 

    class func appBuild() -> String { 
     return Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String 
    } 

    class func versionBuild() -> String { 
     let version = appVersion(), build = appBuild() 

     return version == build ? "v\(version)" : "v\(version)(\(build))" 
    } 
}

下面是Objective-C中的等價物：

+ (NSString *) appVersion 
{ 
    return [[NSBundle mainBundle] objectForInfoDictionaryKey: @"CFBundleShortVersionString"];  
} 

+ (NSString *) build 
{ 
    return [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString *)kCFBundleVersionKey]; 
} 

+ (NSString *) versionBuild 
{ 
    NSString * version = [self appVersion]; 
    NSString * build = [self build]; 

    NSString * versionBuild = [NSString stringWithFormat: @"v%@", version]; 

    if (![version isEqualToString: build]) { 
     versionBuild = [NSString stringWithFormat: @"%@(%@)", versionBuild, build]; 
    } 

    return versionBuild; 
}

在斯威夫特，您可以通過使用得到包版本：

let info:NSDictionary = NSBundle.mainBundle().infoDictionary! 

let version:String = info.objectForKey("CFBundleShortVersionString") as! String 

versionLabel.text = "Version:" + version 

Answer 3

的我的開源項目，App Update Tracker

• + (NSString *)getShortVersionString
• + (NSString *)getLongVersionString

你會使用它像這樣：在類方法的形式提供了這個功能（及以上）

#import "AppUpdateTracker.h" 

NSLog(@"short version: %@", [AppUpdateTracker getShortVersionString]); 
NSLog(@"long version: %@", [AppUpdateTracker getLongVersionString]); 

Answer 4

因此，繼承人一個斯威夫特版本這兩個分別：

let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String 
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

Answer 5

在Objective C：

1）爲了得到應用的版本，你必須使用一個：

NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]; 

2 ）爲了得到構建的版本，你必須使用一個：

NSString *buildVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]; 

Answer 6

下面是對Xcode中8的工作，斯威夫特3：

let gAppVersion = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") ?? "0" 
let gAppBuild = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") ?? "0" 

print("Version: \(gAppVersion)") 
print("Build: \(gAppBuild)") 

Answer 7

只是做筆記

要獲得任意鍵的本地化值，你應該使用CFBundleGetValueForInfoDictionaryKey(CFBundleGetMainBundle(), "CFBundleShortVersionString" as CFString)
