I'm of the mindset that one should try to get rid of all warnings that
show up when compiling a program, which is why I'm asking this. I use
an NSTimer in my application, set up like this in an awakeFromNib:
NSTimer *statusTimer = [NSTimer scheduledTimerWithTimeInterval: 5.0
target:self selector:@selector(checkStatus) userInfo:nil repeats:YES];
When I compile, the only warning I get is "unused variable
'statusTimer'." However, my timer works just fine, no problems at all.
Is there something I should/could do to get rid of the warning, or is
it harmless?
In addition to what everyone else has told you, there is a way to
disable those warnings for variables you know are unused without
turning it off completely: #pragma unused(). For example:
NSString *unusedString = [NSString string];
#pragma unused(unusedString)
