iOS gets the device name and version number of the current app

Without saying much, please look at the code:

NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary]; 
 CFShow(infoDictionary); 
// app Name  
 NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"]; 
 // app Version  
 NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"]; 
 // app build Version  
 NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"]; 

  // Mobile phone serial number  
  NSString* identifierNumber = [[UIDevice currentDevice] uniqueIdentifier]; 
  NSLog(@" Mobile phone serial number : %@",identifierNumber); 
  // Mobile Alias:   User-defined name  
  NSString* userPhoneName = [[UIDevice currentDevice] name]; 
  NSLog(@" Cell phone alias : %@", userPhoneName); 
  // Device name  
  NSString* deviceName = [[UIDevice currentDevice] systemName]; 
  NSLog(@" Device name : %@",deviceName ); 
  // Mobile phone system version  
  NSString* phoneVersion = [[UIDevice currentDevice] systemVersion]; 
  NSLog(@" Mobile phone system version : %@", phoneVersion); 
  // Mobile phone model  
  NSString* phoneModel = [[UIDevice currentDevice] model]; 
  NSLog(@" Mobile phone model : %@",phoneModel ); 
  // Local model   (Name of Internationalized Region)  
  NSString* localPhoneModel = [[UIDevice currentDevice] localizedModel]; 
  NSLog(@" Internationalized zone name : %@",localPhoneModel ); 

  NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary]; 
  //  Current application name  
  NSString *appCurName = [infoDictionary objectForKey:@"CFBundleDisplayName"]; 
  NSLog(@" Current application name: %@",appCurName); 
  //  Current application software version   For example: 1.0.1 
  NSString *appCurVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"]; 
  NSLog(@" Current application software version :%@",appCurVersion); 
  //  Current application version number   int Type  
  NSString *appCurVersionNum = [infoDictionary objectForKey:@"CFBundleVersion"]; 
  NSLog(@" Current application version number: %@",appCurVersionNum);
