在运行时获取供应配置文件的EXPIRATION日期?

标签: ios notifications runtime provisioning profiles

我有一个应用程序,我经常通过ad-hoc分发方法传递给测试人员。其中一些测试人员“关注”并且对配置文件和季度到期有足够的了解,并且可以(如果我忘了)给我一个重建新版本供他们测试的推动。

然而,有些用户似乎总是达到停止运行的程度,然后对此嗤之以鼻 - 尽管他们可能会忽略iOS级别的提醒。

我的问题是,我可以在运行时以编程方式获取到期日期并执行我自己的“应用内”警报或系统通知,以提醒他们下拉新版本吗?

您正在寻找类似

的内容
"<key>ExpirationDate</key><date>2014-12-06T00:26:10Z</date>" in [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"]

但要到那里并不容易!此代码可以改进,部分内容基于其他stackoverflow帖子。注意:另一种选择是在项目plist之间加载所有内容 和/ plist into ... plist(字典)。但由于我们已经在那里,我们只是手工找到兄弟姐妹。

- (NSString*) getExpiry{

    NSString *profilePath = [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"];
    // Check provisioning profile existence
    if (profilePath)
    {
        // Get hex representation
        NSData *profileData = [NSData dataWithContentsOfFile:profilePath];
        NSString *profileString = [NSString stringWithFormat:@"%@", profileData];

        // Remove brackets at beginning and end
        profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(0, 1) withString:@""];
        profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(profileString.length - 1, 1) withString:@""];

        // Remove spaces
        profileString = [profileString stringByReplacingOccurrencesOfString:@" " withString:@""];


        // Convert hex values to readable characters
        NSMutableString *profileText = [NSMutableString new];
        for (int i = 0; i < profileString.length; i += 2)
        {
            NSString *hexChar = [profileString substringWithRange:NSMakeRange(i, 2)];
            int value = 0;
            sscanf([hexChar cStringUsingEncoding:NSASCIIStringEncoding], "%x", &value);
            [profileText appendFormat:@"%c", (char)value];
        }

        // Remove whitespaces and new lines characters
        NSArray *profileWords = [profileText componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

        //There must be a better word to search through this as a structure! Need 'date' sibling to <key>ExpirationDate</key>, or use regex
        BOOL sibling = false;
        for (NSString* word in profileWords){
            if ([word isEqualToString:@"<key>ExpirationDate</key>"]){
                NSLog(@"Got to the key, now need the date!");
                sibling = true;
            }
            if (sibling && ([word rangeOfString:@"<date>"].location != NSNotFound)) {
                NSLog(@"Found it, you win!");
                NSLog(@"Expires: %@",word);
                return word;
            }
        }

    }

快速版本:

// Returns `nil` if it fails
private func getProvisioningProfileExpirationDateAsString() -> String? {
    guard
        let profilePath = Bundle.main.path(forResource: "embedded", ofType: "mobileprovision"),
        let profileData = try? Data(contentsOf: URL(fileURLWithPath: profilePath)),
        // Note: We use `NSString` instead of `String`, because it makes it easier working with regex, ranges, substring etc.
        let profileNSString = NSString(data: profileData, encoding: String.Encoding.ascii.rawValue)
        else {
        print("WARNING: Could not find or read `embedded.mobileprovision`. If running on Simulator, there are no provisioning profiles.")
        return nil
    }


    // NOTE: We have the `[\\W]*?` check to make sure that variations in number of tabs or new lines in the future does not influence the result.
    guard let regex = try? NSRegularExpression(pattern: "<key>ExpirationDate</key>[\\W]*?<date>(.*?)</date>", options: []) else {
        print("Warning: Could not create regex.")
        return nil
    }

    let regExMatches = regex.matches(in: profileNSString as String, options: [], range: NSRange(location: 0, length: profileNSString.length))

    // NOTE: range `0` corresponds to the full regex match, so to get the first capture group, we use range `1`
    guard let rangeOfCapturedGroupForDate = regExMatches.first?.range(at: 1) else {
        print("Warning: Could not find regex match or capture group.")
        return nil
    }

    let dateAsString = profileNSString.substring(with: rangeOfCapturedGroupForDate)
    return dateAsString
}

在iOS 13中,它不起作用。 NSData的描述从

{0x30822755 06092a86 4886f70d 010702a0 ... 889bfcbe ed768bac }

{length = ..., bytes = 0x30822755 06092a86 4886f70d 010702a0 ... 889bfcbe ed768bac }

尝试以下代码:

NSData *data = ....;
NSUInteger dataLength = [data length];
NSMutableString *string =[NSMutableString stringWithCapacity:dataLength*2];

const unsigned char *dataBytes = [data bytes];
for (NSInteger idx = 0; idx < dataLength; ++idx)
{
    [string appendFormat:@"%02x", dataBytes[idx]];
}

在 iOS 13 中,为了简化 Ttnka 的建议,您可以使用 profileData.debugDescription 来创建 profileString(来自最初发布的 Objective-C 代码):

NSString *profileString = [NSString stringWithFormat:@"%@", profileData.debugDescription];

结合@Pierre-Francoys Brousseau 和@Ttnka 的回答:

        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13.0)
        {
            NSUInteger dataLength = [profileData length];
            NSMutableString *string =[NSMutableString stringWithCapacity:dataLength*2];
