Programming in Objective-C Programming in Objective-C
Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming. The book makes no assumption about prior experience with object-oriented programming languages or with the C language (upon which Objective-C is based). And because of this, both novice and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C.

Installing things to /usr/bin - Trampolines

Published in: Objective C 

URL: http://briksoftware.com/blog/?p=70

Instead of installing the real tools I install 2 trampoline applications in /usr/bin called respectively pdflock and pdfunlock. The trampoline then uses NSWorkspace to locate the bundle, and starts the real executable found in the application’s bundle.


Plain TextExpand 
  1. int main(int argc, char *argv[])
  2. {
  3. 	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
  4. 	NSWorkspace *env = [NSWorkspace sharedWorkspace];
  5. 	NSString *app = [env absolutePathForAppBundleWithIdentifier:@"com.pdfkey.pdfkeypro"];
  6. 	NSString *targetPath = [[app stringByAppendingPathComponent:@"Contents/Resources/pdflock"] retain];
  7.  
  8. 	const char *CStringPath = [targetPath UTF8String];
  9. 	[pool release];
  10.  
  11. 	execv(CStringPath, argv);
  12.  
  13. 	// You reach this code only if execv returns, which means that something wrong happened.
  14. 	[targetPath release];
  15. 	printf("PDFKey Pro is not installed. Please download it from http://pdfkey.com\n");
  16. 	return 0;
  17. }
