How to create a method in Objective-C that takes an NSString stringWithFormat parameter as a parameter?

Question

I'm not sure the title is clear. I want to make a convenient method that works like the NSLog method and concatenates the lines below?

This is what I have at the moment:

NSString *out = [NSString stringWithFormat:@"something %d,%d",1,2];
[self showLog:out];

What would a similar method look like in a definition?

- (void) showLog:(NSString *) data;

Answer 1

In interface

-(void) showLog: (NSString*) formatSpecifier, ...;

In implementation

-(void) showLog: (NSString*) formatSpecifier, ...
{
    va_list formatArgs;
    va_start(formatArgs, formatSpecifier);
    NSString* logMessage = [[NSString alloc] initWithFormat: formatSpecifier arguments: formatArgs];
    va_end(formatArgs);

    // Do want you need to to output the string.

    [logMessage release];
}

@implementation SampleClass
  //<<<<<<<<<<-- Function to print UserName -->>>>>>>>>>>>>>>

int main ()
{
 SampleClass *sampleClass = [[SampleClass alloc]init];
