how can i pass an int value through a selector method?

Question

I want to pass an int value from my selector method, but the selector method takes only an object type parameter.

int y =0;
[self performselecto

This works also for an int parameter, which is especially useful, if you are unable to change the signature of the selector you want to perform.

SEL sel = @selector(tabledata:);

NSMethodSignature *signature = [[self class] instanceMethodSignatureForSelector:sel];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
invocation.selector = sel;
// note that the first argument has index 2!
[invocation setArgument:&y atIndex:2];

// with delay
[invocation performSelector:@selector(invokeWithTarget:) withObject:self afterDelay:0.1];
