How to get Target name?

问题:

We know that Xcode maintains environment variable of ${TARGET_NAME} but how to access this variable in objective-C code ?

What I have tried ?
I have added "TARGET_NAME=${TARGET_NAME}" this in Preprocessor macros section of Build Settings. But now I am not sure how to use this variable "TARGET_NAME" as a string in objective-C code.

In my case product name and target name are different so, no chance to use that.

I tried to access using

#ifdef TARGET_NAME
 NSLog(@"TargetIdentifier %@",TARGET_NAME);
#endif

This code is giving error like "Use of undeclared identifier 'myapptargetname'"

You can add "TargetName" key to your Info.plist file:

Then you can access it (swift code):

var plistFileName = NSBundle.mainBundle().infoDictionary?["TargetName"] as String

回答2:

NSLog(@"Target name: %@",[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleName"]);

Hope to help you!

Edited: "CFBundleName" thanks Max and Daniel Bo for your commend

Swift 4, Xcode 9+

Bundle name:

Bundle.main.object(forInfoDictionaryKey: "CFBundleName") as? String ?? ""

Bundle display name:

Bundle.main.object(forInfoDictionaryKey: "CFBundleDisplayName") as? String ?? ""

Swift 3, Xcode 8+

let targetName = Bundle.main.infoDictionary?["CFBundleName"] as? String ?? ""

回答4:

In Xcode 7.3.1

if let targetName = NSBundle.mainBundle().infoDictionary?["CFBundleName"] as? String{
    print(targetName)
}

** For Swift 4 **

I am not sure how good it is to have a Constants file in Swift but you could create something like that:

enum TargetType:String, CaseIterable{
    case target1 = "My Target 1"
    case target 2 = "My Target 2"
    case unknown
}

var currentTarget:TargetType = {
    return TargetType(rawValue: (Bundle.main.object(forInfoDictionaryKey: "CFBundleName") as? String ?? "")) ?? .unknown
}()

So you can called it any time like that

if currentTarget != .unknown{
    print(currentTarget.rawValue)
}

If you want to add the variable inside a Constants class then:

class Constants: NSObject {

    static var currentTarget:TargetType = {
        return TargetType(rawValue: (Bundle.main.object(forInfoDictionaryKey: "CFBundleName") as? String ?? "")) ?? .unknown
    }()

}
