when phone call -[uitableview reloaddata] method telling tableview refresh ints content based on source gave him, doesnt alter source. in cases refresh datasource , need refresh uitableview phone call -[uitableview reloaddata]. need first refresh info , refresh view, view uses new data.

use the same way got info modal refresh it.

self.blogpost.jsonmutable = [nsmutablearray array]; (nsdictionary *post in self.blogpost.blogdata) { armodal *bp = [armodal blogpostwithhome:[[post objectforkey:@"home"] objectforkey:@"text"]]; bp.away = [[post objectforkey:@"away"] objectforkey:@"text"]; bp.result = [[post objectforkey:@"result"] objectforkey:@"text"]; bp.info = [post objectforkey:@"info"]; bp.homeimage = [[post objectforkey:@"homeimage"] objectforkey:@"src"]; [self.blogpost.jsonmutable addobject:bp]; }

then execute -[uitableview reloaddata], going refresh using refreshed info got modal.

if need else, comment.
