Question

I’m using the library STPrivilegedTask library, source found at http://www.sveinbjorn.org/STPrivilegedTask to run the NSTask with sudo permissions.

This is the code I’m using to instantiate an STPrivilegedTask object but I’m getting syntax error:

STPrivilegedTask *task2 = [[STPrivilegedTask alloc] initWithLaunchPath: launchPath: arguments];

I’m getting “Receiver type STPrivilegedTask for instance method does not declare a method…” error. Is the above syntax valid?

Thanks,

Not an expert in objective-C, but if I’m not wrong, you should call it like that:

STPrivilegedTask *task2 = [[STPrivilegedTask alloc] initWithLaunchPath: launchPath
arguments:arguments];

(Assuming arguments in your method is your NSArray) Since the declaration of the method is:

- (id)initWithLaunchPath: (NSString *)path arguments:  (NSArray *)args;
                                           ^^^ Part of the method signature

And not

- (id)initWithLaunchPath: (NSString *)path :  (NSArray *)args;

This is an example from the .m file in the link you added:

STPrivilegedTask *task = [[[STPrivilegedTask alloc] initWithLaunchPath: path arguments: args] autorelease];
