是否可以通过编程确定iOS目标

Question

I would like to be able to switch certain functionality on/off in an iOS app depending on whether it is the release version or not. Is it possible to programmatically whether the current build is the release version or not? I know similar functionality can be achieved through the use of macros, but as I understand it these would not work if the code in question is inside a static library.

Answer 1

create a flag in your scheme and use it like

#ifdef BETA

so say you want to have a string method returning two different strings for two different states

- (NSString *)someString {

  #ifdef BETA
    return @"Beta String";
  #else
    return @"Release String";
  #endif

}

You could use the built in

#ifdef DEBUG

this would differentiate between release and debug

I wouldnt recommend having two different targets.

Answer 2

As H2CO3 said:

#ifdef DEBUG
    NSLog(@"Debug mode");
#endif

Answer 3

Just set Target name in your Scheme -> Environment Variables -> add Name and Value. eg: targetName = "mytesttarget"

Obj-c

NSDictionary* envir = [[NSProcessInfo processInfo] environment];  
NSString* targetName = envir[@"targetName"];

Swift

let envir = NSProcessInfo.processInfo().environment  
let targetName = envir["targetName"]

Now you can check the target condition

if targetName == "mytesttarget" {  
...  
} else {  
...  
}

Swift 4:

let envir = ProcessInfo.processInfo.processName  
let targetName = envir["targetName"]
