Getting Current Directory in Objective C

I am trying to get current directory, but its giving me path of DEBUG folder, how i can get the path of current directory. I am using the following code.

NSFileManager *filemgr;
NSString *currentpath;

filemgr = [开发者_如何转开发[NSFileManager alloc] init];

currentpath = [filemgr currentDirectoryPath];

currentDirectoryPath returns the current working directory of the program. If you launch it from Xcode in Debug mode, the current directory of the program is the Debug directory.

Developing further on that. The current working directory and launch directory may be different! Take this example, the app is launched from the home directory (~).

Library/Developer/Xcode/DerivedData/MyApp-ehwczslxjxsxiob/Build/Products/Debug/MyApp.app/Contents/MacOS/MyApp -param value

NSString *p1 = [[NSFileManager defaultManager] currentDirectoryPath];
// p1 = ~/Library/Containers/com.MyApp.beta/Data
NSString *p2 = [[NSProcessInfo processInfo] environment][@"PWD"];
// p2 = ~

Depending on the situation you might want one or the other. In my case I want to provide a CLI which takes path arguments that may be relative to the current working directory in the shell.

When getting paths for a service loaded via launchd, the paths can be very different.

NSLog(@"argv: %s", argv[0]);
NSLog(@"NSProcessInfo: %@", NSProcessInfo.processInfo.arguments[0]);
NSLog(@"currentDirectoryPath: %@", [[NSFileManager defaultManager] currentDirectoryPath]);
NSLog(@"PWD: %@", [[NSProcessInfo processInfo] environment][@"PWD"]);

Output:

argv: /Users/dev/.ioi/default-runtime-manager/default-runtime-manager
NSProcessInfo: /Users/dev/.ioi/default-runtime-manager/default-runtime-manager
currentDirectoryPath: /Users/dev/Library/Application Support/IOI/default-runtime-manager
PWD: (null)

• NSProcessInfo gives the location where the executable was found.
• currentDirectoryPath returns the WorkingDirectory specified in the launchd plist.

The answer to getting the executable path was found here: StackOverflow: NSProcessInfo. The other paths were from: @lupdidup
