Objective-C: How to call performSelector with a BOOL typed parameter?

Is there any way to send a BOOL in selector ?

[self performSelector:@selector(doSomething:) withObject:YES afterDelay:1.5];

Or I should use NSInvocation? Could somebody write a sample please ?

Solution

  • you can use NSNumber to wrap bools types:

    BOOL myBool = YES;
NSNumber *passedValue = [NSNumber numberWithBool:myBool];
[self performSelector:@selector(doSomething:) withObject:passedValue afterDelay:1.5];

    and in the selector, to get the bool value, you use:

    BOOL value = [recievedObject boolValue];
