iphone - Dynamic VariableFromString in objective C -

-

i want dynamically create variable string in objective c.

like nsclassfromstring thats way. in want access variable.

any idea this?

if want dynamically access property of object, that's easy using key value coding.

if class kvc-compliant (most apple classes are), use valueforkey:, or valueforkeypath: method access property string.

consider example.

// shoe.h @interface shoe {     nsstring *brand;     nsnumber *size; }  @property (nonatomic, copy) nsstring *brand; @property (nonatomic, retain) nsnumber *size;  @end  // shoe.m @implementation   @synthesize brand, size;  @end

let's create , initialize shoe object first.

shoe *someshoe = [[shoe alloc] init]; someshoe.brand = @"adidas"; someshoe.size = [nsnumber numberwithfloat:9.5];

considering example someshoe object, brand or size can accessed via string.

nsstring *brandname = [someshoe valueforkey:@"brand"];

(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."
