iphone - Problem adding custom objects to Mutable Array -

quick question regarding array's in xcode. have ht efollowing code, supposed go through array of strings has got through php , json, , trun these strings custom object strings ivars object add object new array:

for (int = 0; i<[list count]; i++) {         article *article = [[article alloc] init]; //creates custom object         article.uid = [[list objectatindex:i] objectatindex:0];         article.title = [[list objectatindex:i] objectatindex:1]; //adds string ivars         article.description = [[list objectatindex:i] objectatindex:2];         articlearray = [[nsmutablearray alloc] init]; //inits new array         [articlearray addobject:article]; //should add object seems fail         [article release]; //releases object         nslog(@"%@", article.description);     }     nslog(@"%d", [articlearray count]);     nslog([articlearray description]); } 

the code return correct values using nslog(@"%@", article.description); not correct length new array , adds 1 value array string article.description makes no sense me. list array contains 2 elements each of arrays in containing strings.

you're recreating articlearray in every loop. declarate outside, , work:

nsmutablearray *articlearray = [[nsmutablearray alloc] init]; //inits new array (int = 0; i<[list count]; i++) {         article *article = [[article alloc] init]; //creates custom object         article.uid = [[list objectatindex:i] objectatindex:0];         article.title = [[list objectatindex:i] objectatindex:1]; //adds string ivars         article.description = [[list objectatindex:i] objectatindex:2];         [articlearray addobject:article]; //should add object seems fail         [article release]; //releases object         nslog(@"%@", article.description);     }     nslog(@"%d", [articlearray count]);     nslog([articlearray description]); } 

you may want use nicer for(nsarray *listelement in list) syntax instead.
