Get common application and device information in iOS development

1. Get Version number:

Version of the key in the plist file is "cfbundleshortversionstring", and on the App Store, the number is consistent, build in Plist key is "cfbundleversion", Represents the version number of the build, which should be increased by 1 after each builds.

[[[[NSBundle Mainbundle] infodictionary] objectforkey:@ "cfbundleshortversionstring"];

[[NSBundle mainbundle]objectforinfodictionarykey:@ "cfbundleshortversionstring"];

[[[[NSBundle Mainbundle] infodictionary] objectforkey:@ "cfbundleversion"];

2. Get mobile network status and carrier information

Import

coretelephony.framework

Introducing Header Files

#import <CoreTelephony/CTTelephonyNetworkInfo.h>

#import <CoreTelephony/CTCarrier.h>

2.1 Get mobile phone network shape

<strong><span style= "FONT-SIZE:14PX;" >-(void) networktype{nsarray *subviews = [[[UIApplication Sharedapplication] valueforkey:@ "StatusBar"] ValueForK  
    ey:@ "Foregroundview"]subviews];  
    NSNumber *datanetworkitemview = nil; For (ID subview in subviews) {if ([Subview iskindofclass:[nsclassfromstring (@ "Uistatusbardatanetworkitemview") c  
            Lass]] {datanetworkitemview = Subview;  
        Break  
            switch ([[Datanetworkitemview valueforkey:@ Datanetworktype "]integervalue]) {case 0:  
            NSLog (@ "No WiFi or cellular");  
            infolabel.text=@ "no service";  
        Break  
            Case 1:nslog (@ "2G");  
            infolabel.text=@ "2G";  
        Break  
            Case 2:nslog (@ "3G");

        Break  
            Case 3:nslog (@ "4G");  
            infolabel.text=@ "4G";  
        Break  
Case 4:            NSLog (@ "LTE");  
            infolabel.text=@ "LTE";  
        Break  
            Case 5:nslog (@ "Wifi");  
            infolabel.text=@ "Wifi";                
        Break  
    Default:break; }} </span></strong>

2.2 Get carrier information

<span style= "color: #333333;" >-(nsstring*) getoperatorname{  
    cttelephonynetworkinfo *telephonyinfo = [[Cttelephonynetworkinfo alloc] init];  
    Ctcarrier *carrier = [Telephonyinfo subscribercellularprovider];  
    NSString *currentcountry=[carrier Carriername];  
    NSLog (@ "[Carrier Isocountrycode]==%@,[carrier Allowsvoip]=%d,[carrier Mobilecountrycode=%@,[carrier mobilecountrycode]=%@ ", [Carrier Isocountrycode],[carrier allowsvoip],[carrier Mobilecountrycode],[carrier Mobilenetworkcode]);  
    return currentcountry;  
} </span>
