Isses using function with variadic arguments
- by Sausages
I'm trying to write a logging function and have tried several different attempts at dealing with the variadic arguments, but am having problems with all of them. Here's the latest:
- (void) log:(NSString *)format, ...
{
if (self.loggingEnabled)
{
va_list vl;
va_start(vl, format);
NSString* str = [[NSString alloc] initWithFormat:format arguments:vl];
va_end(vl);
NSLog(format);
}
}
If I call this like this:
[self log:@"I like: %@", @"sausages"];
Then I get an EXC_BAD_ACCESS at the NSLog line (there's also a compiler warning that the format string is not a string literal).
However if in XCode's console I do "po str" it displays "I like: sausages" so str seems ok.
