So this line is not within any method of function, but is the global
declaration in the file?  That's why.  You can initialize an NSString
outside of a block of code like this:

NSString *foo = @"bar";

But that only works because @"bar" is a constant string, so the compiler
can deal with it.  You're including allocation and initialization,
meaning that what you're assigning to temp1PDF is not a constant.

You need to trim that down to just the declaration:

PDFDocument *temp1PDF;

...and then put the alloc/init inside a block of code somewhere,
presumably an initialization method.

I tried to do like you said :

#import "AppController.h"

PDFDocument *temp1PDF;

@implementation AppController

- (id) init
{

temp1PDF= [[[PDFDocument alloc] initWithURL: [NSURL
fileURLWithPath:path_file]] autorelease];
return self;
}
- (IBAction)LoadPDF:(id)sender
{
NSString *filename = @"/volumes/macintosh hd/PDFS/test.pdf";
docPDF = [[[PDFDocument alloc] initWithURL: [NSURL
fileURLWithPath:filename]] autorelease];
}

- (IBAction)writePdf:(id)sender
{

NSString *search = @"3533168";
[docPDF setDelegate :self];
[docPDF beginFindString: search withOptions: NSCaseInsensitiveSearch];

}

- (void) didMatchString: (PDFSelection *) instance
{

[temp1PDF insertPage: [docPDF pageAtIndex:0]   atIndex: 0];
++pp ;

}

It has no errors during the compilation, but it raises runtime error
when the delegate is called and tries to write something to
temp1PDF.
What should it be ? Thanks a lot!!
