objective c - How to access files in interior of an iPhone App? -

-

i need in iphone app access files app build with(.plist etc). there's hardcoded way this: 

nsstring *appdir = [[[nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes)                       objectatindex:0]                       stringbydeletinglastpathcomponent]                     stringbyappendingpathcomponent:appfolder];

where appfolder name of folder app, "test.app". after appdir known, access files simple.

is there other, not-hardcoded way have access files form app?

thanks in advance!

 nsstring* pathtofile =      [[[nsbundle mainbundle] resourcepath]           stringbyappendingpathcomponent:@"myfile.plist"];  // or, better (handling localization): nsstring* pathtofile = [[nsbundle mainbundle] pathforresource:@"myfile"                                                        oftype:@"plist"];

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
