iphone - NSMutableAttributedString on iOS 3.1.3 -

-

i'm dealing odd situation. i'm implementing attributed strings ios application, , had warning going in available ios 3.2 , above. because still support 3.1.3 on iphones, knew had weakly link coretext , compile time os check before using them.

i weakly linked framework, out of curiosity used class , ran on 3.1.3 device... , works. missing here, i'm confused why isn't crashing. i'm 100% sure 3.1.3 device, nsmutableattributedstring hidden class on 3.1.3, , work because of dynamic nature of objective-c ?

i author of ohattributedlabel class. using it!

the behavior have strange, ohattributedlabel uses coretext framework draw nsattributedstrings on screen.

as coretext available since ios 3.2, can't see how possible work under ios 3.2, ios 3.1.3…?

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."
