ios - Increase table row height dynamically -


i have table 1 custom cell 1 label , 1 textfield.am re-using same cell 5 rows. want display 1 view beneath textfield if user enters on textfield. when entering data in first textfield view should hidden other rows , respectively other rows. default height must 120 , when displaying view row height should increased 250. here code,

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {        return 120; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {  static nsstring *cellidentifier = @"detailstablecell"; cell = (newsdetailstableviewcell *)[tableview dequeuereusablecellwithidentifier:cellidentifier]; if (cell == nil) {     cell = [[newsdetailstableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellidentifier]; } if (indexpath.row == 0) {     cell.newview.tag = 200; } else if (indexpath.row == 1) {     cell.newview.tag = 201; } else {     cell.newview.tag = 202; }     return cell; }

here new view uiview displaying on text change.

- (ibaction)textfieldchanged:(uitextfield *)textfield replacementstring:(nsstring *)string {  nsindexpath *indexpath = [newstable indexpathforcell:(newsdetailstableviewcell*)[[textfield superview] superview]]; nsindexpath *mypath = [nsindexpath indexpathforrow:indexpath.row insection:indexpath.section]; newsdetailstableviewcell *newstablecell = (newsdetailstableviewcell*)[newstable cellforrowatindexpath:mypath];   if (indexpath.row == 0 && newstablecell.newview.tag == 100) {     newstable.rowheight = 250;     newstablecell.newview.hidden = false;  } else if (indexpath.row == 1 && newstablecell.newview.tag.tag == 101) {     newstable.rowheight = 250;     newstablecell.newview.hidden = false; } else {     newstable.rowheight = 250;     newstablecell.newview.hidden = false;    } }

am getting view in text change row height not getting changed. still showing 120 height.

also tried this,

nsarray* rowstobereloaded = [nsarray arraywithobjects:indexpath, nil]; [newstable reloadrowsatindexpaths:rowstobereloaded withrowanimation:uitableviewrowanimationnone];

but didn't work. should re-load tableview again in text change? or missing something?

you have modify logic in below method:enter image description here

the selectedrownum can modified per row in textfield shown. also, cellforrowatindexpath not used setting height of rows in tableview. everytime, call reloaddata or reloadindexes heightforrowatindexpath method called.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
