ios - Reload UITableView without reloading header section -

-

i have uitableview section , index title. when user click on cell option view of height 42 gets display in cell. display option reload cell. section header getting updated. gives bizarre animation. how reload cell,without getting called other delegate method heightforheaderinsection , viewforheaderinsection.

there several methods reloading tableview.

  1. to reload whole section including section's cell.

    - (void)reloadsections:(nsindexset *)sections withrowanimation:(uitableviewrowanimation)animation

example:

[tableviewcontent reloadsections:[nsindexset indexsetwithindex:1] withrowanimation:uitableviewrowanimationautomatic];

  1. to reload single/multiple cells

    - (void)reloadrowsatindexpaths:(nsarray<nsindexpath > )indexpaths withrowanimation:(uitableviewrowanimation)animation

example:

[tableview reloadrowsatindexpaths:[nsarray arraywithobject:[nsindexpath indexpathforrow:0 insection:1]] withrowanimation:uitableviewrowanimationfade];

  1. to reload whole tableview.

    - (void)reloaddata;

    // reloads scratch. redisplays visible rows. because keep info visible rows, cheap. adjust offset if table shrinks

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
