谓词搜索searchbar
各位我刚刚在做tableview和searchbar的谓词搜索功能的时候遇到了这样问题。我通过谓词过滤没办法去过滤那种数组中字典,好比如下面这个数组。我用 NSString *str = [NSString stringWithFormat:@"SELF.information LIKE[cd] '*%@*'",searchString];self.filteredContents = [NSMutableArray arrayWithArray:[self.dataArray filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:str]]];却没办法搜索到内容
