Question

Need code snippets in objective c for iPhone sdk.

Asked by: watunda

I am programming an alternative keypad for the iPhone and am new to objective c and iPhone sdk.   I need each button press to append a letter to a string and then refresh an output window with the new string.  Like a simple terminal emulator/ text editor.  I know C and Java but struggling with objective c syntax.  Thanks.

You can always use the C functions if you like. In your case it seems the following does what you like

#include <Foundation/Foundation.h>
int
main(void)
{
  id pool = [[NSAutoreleasePool alloc] init];
  int seconds = 180;
  NSMutableString *someString;
  someString = [NSMutableString stringWithCString: "I'm a String"];
  
  [someString appendFormat: @" %d ", 10];
  
 NSLog(@"someString is now '%@'\n", someString);
  // The end...
  [pool release];
 
  return 0;
}
 
Output: 2008-05-09 09:36:43.556 test1[5903] someString is now 'I'm a String 10 '
