iOS app, programmatically get build version
Is there a way to programmatically get the build version of my app? I need to be able to detect when the user has updated the app through the AppStore, in order to execute some code for adjustments
The value you set in the Xcode target summary's "Version" field is in here:
Swift 3
let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as! String
ObjC
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
Swift 2
let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String
and the "Build":
Swift 3
let build = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as? String
ObjC
NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];
Swift 2
let build = NSBundle.mainBundle().infoDictionary?[kCFBundleVersionKey as String] as! String
You can try using the infoDictionary
NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];
NSString *version = infoDictionary[@"CFBundleShortVersionString"];
NSString *build = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey];
When using MFMailComposeViewController for 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:
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:
Swift version for both separately:
let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

1)For getting App version you have to use a:
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
2)For getting Build version you have to use a:
NSString *buildVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
