I'm trying to perform performSelector selecting methods from nsarray but I'm getting this error:

performSelector may cause a leak beacause its selector is unknown

Here is my code:

-(void)exceudeMethods
{
    NSArray *methods = @[@"methodOne",@"methodTwo"];

    for (int i =0 ; i < methods.count; i++)
    {
       [self performSelector:NSSelectorFromString([NSString stringWithFormat:@"%@:",methods[i]])];

    }

}

if I replace any of you know how can I fix this so I can execute all the methods in the nsarray?

Answer 1

strange that the warning is removed if you replace the line with

    [self  performSelector:NSSelectorFromString(methods[i]) withObject:nil afterDelay:0.0f];

seems to work.
