iOS app, programmatically get build version
提问by jcardenete

The value you set in the Xcode target summary's "Version" field is in here:
您在 Xcode 目标摘要的“版本”字段中设置的值在这里：
Swift 3

let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as! String
ObjC
对象
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String
and the "Build":
和“构建”：

let build = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as? String
ObjC

NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];
Swift 2

You can try using the infoDictionary
您可以尝试使用 infoDictionary
NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];
NSString *version = infoDictionary[@"CFBundleShortVersionString"];
NSString *build = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey];

When using MFMailComposeViewControllerfor a "Contact Us" button, I use this code to get a formatted HTML on the e-mail from the user. It gives me all the info that I need to start helping solving any issue:
当MFMailComposeViewController用于“联系我们”按钮时，我使用此代码从用户的电子邮件中获取格式化的 HTML。它为我提供了开始帮助解决任何问题所需的所有信息：
struct utsname systemInfo;
uname(&systemInfo);
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
NSDate *date = [NSDate date];
[formatter setDateFormat:@"MM/dd/yyyy 'at' hh:mm a"];
NSString *dateString = [formatter stringFromDate:date];
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width - 65.0;
NSString *comments = NSLocalizedString(@"Please write your comments below:", nil);
NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
NSString *appName = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString*)kCFBundleNameKey];
NSString *deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
NSString *iOSVersion = [[UIDevice currentDevice] systemVersion];
NSString *emailBody = [NSString stringWithFormat:@"<!DOCTYPE html><html><style> .div {background-color: lightgrey; width: %fpx; padding: 10px; border: 5px solid navy; margin: 2px;}</style><body><div class='div'><p><b>App:</b> %@</p><b><p>Device:</b> %@</p><b><p>iOS Version:</b> %@</p><b><p><p>App Version and Build:</b> %@ (%@)</p><b><p>Date:</b> %@</p> </p></div><font color='red'><b>%@</b></font><br><br></body></html>",screenWidth,appName,deviceModel,iOSVersion,version,build,dateString,comments];
[self setMessageBody:emailBody isHTML:YES];
This is the result when getting the message:
这是收到消息时的结果：

Swift version for both separately:
Swift 版本分别用于：
let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

I have written this open source projectfor precisely this purpose. My project posts notifications when significant events occur, such as when a user opens the app for the first time, or opens the app after upgrading (complete with information on which version the user upgraded from). The source is straightforward and should be easy to understand. Let me know if you have any questions/requests.
我正是为此目的编写了这个开源项目。我的项目在发生重大事件时发布通知，例如当用户第一次打开应用程序时，或在升级后打开应用程序（完成有关用户从哪个版本升级的信息）。来源很简单，应该很容易理解。如果您有任何问题/要求，请告诉我。
I have also recently written a blog postabout it.
