显示应用的构建日期

Question

我能够在模拟器中显示我的应用程序的构建日期，但是每当我将应用程序存档并将其上传到 TestFlight，然后将其安装到设备上时，构建日期都不会显示。

这是我为显示构建日期所做的工作。

首先，我将 CFBuildDate 作为字符串添加到 myproject-info.plist

接下来，我在 Edit Scheme -> Build -> Pre-Actions -> Run Script Action 中添加了以下脚本：

infoplist="$BUILT_PRODUCTS_DIR/$INFOPLIST_PATH"
builddate=`date`
if [[ -n "$builddate" ]]; then
/usr/libexec/PlistBuddy -c "Add :CFBuildDate $builddate" ${infoplist}
/usr/libexec/PlistBuddy -c "Set :CFBuildDate $builddate" ${infoplist}
fi

最后，使用以下代码从 plist 文件中获取构建日期：

NSString *build_date = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBuildDate"];

这会在模拟器中显示构建日期（虽然偶尔不会），但是当通过 TestFlight 部署应用程序时，构建日期永远不会显示。有什么想法吗？

提前致谢。

Answer 1

您可以考虑使用内置的 __DATE__ 和 __TIME__ 宏，它们将返回应用程序构建日期和时间的字符串表示形式。也许他们会对你有更多帮助：

NSString *dateStr = [NSString stringWithUTF8String:__DATE__];
NSString *timeStr = [NSString stringWithUTF8String:__TIME__];

Answer 2

要获取格式为“yyMMddHHmm”的构建日期，您可以尝试以下操作：

+ (NSString *)GetBuildDate {
    NSString *buildDate;

    // Get build date and time, format to 'yyMMddHHmm'
    NSString *dateStr = [NSString stringWithFormat:@"%@ %@", [NSString stringWithUTF8String:__DATE__], [NSString stringWithUTF8String:__TIME__]];

    // Convert to date
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"LLL d yyyy HH:mm:ss"];
    NSDate *date = [dateFormat dateFromString:dateStr];

    // Set output format and convert to string
    [dateFormat setDateFormat:@"yyMMddHHmm"];
    buildDate = [dateFormat stringFromDate:date];

    [dateFormat release];

    return buildDate;
}

尝试将脚本作为构建阶段步骤运行，而不是方案预操作步骤，这样它就会一直运行，而不管您正在生成的构建类型如何。

Swift3

static var buildDate: Date? {
    guard let infoPath = Bundle.main.path(forResource: "Info.plist", ofType: nil) else {
        return nil
    }
    guard let infoAttr = try? FileManager.default.attributesOfItem(atPath: infoPath) else {
        return nil
    }
    let key = FileAttributeKey(rawValue: "NSFileCreationDate")
    guard let infoDate = infoAttr[key] as? Date else {
        return nil
    }
    return infoDate
}

static var prettyBuildDate: String {
    guard let date = buildDate else {
        return "Unknown"
    }
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
    formatter.timeZone = TimeZone(abbreviation: "UTC")
    return formatter.string(from: date)
}

如果您重新定义__DATE__ 和__TIME__，它将在您每次构建应用程序时更新时间。您无需清理或存档即可更新时间，只需运行项目即可。

  #define DATE [NSString stringWithUTF8String:__DATE__]
  #define TIME [NSString stringWithUTF8String:__TIME__]


- (NSString *)getBuildDate {
    NSString *buildDate;

    // Get build date and time, format to 'yyMMddHHmm'
    NSString *dateStr = [NSString stringWithFormat:@"%@ %@", DATE , TIME ];

    // Convert to date
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"LLL d yyyy HH:mm:ss"];
    NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
    [dateFormat setLocale:usLocale];
    NSDate *date = [dateFormat dateFromString:dateStr];

    // Set output format and convert to string
    [dateFormat setDateFormat:@"dd/MM/yyyy-HH:mm"];
    buildDate = [dateFormat stringFromDate:date];

    return buildDate;
}

在 macOS 上，我使用此代码，它从应用程序的 Info.plist 内容中获取构建日期。可能也适用于 iOS，我还没有检查：

+ (NSDate *)buildDate {
    static NSDate *result = nil;
    if (result == nil) { 
        NSDictionary *infoDictionary = NSBundle.mainBundle.infoDictionary;
        NSString *s = [infoDictionary valueForKey:@"BuildDateString"];
        NSISO8601DateFormatter *formatter = [[NSISO8601DateFormatter alloc] init];
        NSDate *d = [formatter dateFromString:s];
        result = d;
    }
    return result;
}

Swift5

let compileDate = String(Date())
let df = DateFormatter()
df.dateFormat = "MMM-dd-yyyy"
let usLocale = NSLocale(localeIdentifier: "en_US")
df.locale = usLocale
let aDate: Date? = df.date(from: compileDate)
