How to use combination of text and variables in NSString?

How would I use a combination of text and variables in a NSString? I know that in an NSLog, it looks like this:

int number = 5; NSLog(@"My favorite number is %i", number);

How would I go about doing something like that in an NSString or even a char variable?

use all the power of old beloved printf formatting.

for objects "%@" will call the description method, so be smart to write this method for every custom class:

-(NSString*)description;
{
 NSString* result = [NSString stringWithFormat(@"%@" .......


}

for example:

-(NSString *)description;
{
    return [NSString stringWithFormat:@"is: %@ %@ %@ ; at: %f %f",
            name, address, img_name,
            coord.latitude, coord.longitude];
}

NSString * str = [NSString stringWithFormat:@"My favorite number is %i", number];

if you just want to read about format specifiers, see: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html

That is fairly simple:

NSString *string = [NSString stringWithFormat:@"My favorite number is %i", number];

its basically the same as nslog.
