Programmatically put a Mac into sleep

Question

I can\'t find any instructions how to put a Mac programmatically into sleep mode (in Objective-C). I\'m sure it should be only one line, but could you give me a hint?

Answer 1

Tom is correct. The AE methods fail if the display is sleeping. pmset sleepnow works 100%.

NSTask  *pmsetTask = [[NSTask alloc] init];
pmsetTask.launchPath = @"/usr/bin/pmset";
pmsetTask.arguments = @[@"sleepnow"];
[pmsetTask launch];
