objective c - How do I programmatically change the size a UIImageView that was created on storyboard with autolayout? -


i have outlet uiimageview hooked storyboard header file. trying alter frame of uiimageview programmatically implementation file. have done following: 

-(void)viewdidload{     [super viewdidload];         if (is_iphone_5) {             someimageview.frame = cgrectmake(someimageview.frame.origin.x, someimageview.frame.origin.y, someimageview.frame.size.width - 50, someimageview.frame.size.height - 50);     } }

no matter change width , height doesn't seem change. using autolayout , have constraints hooked imageview? if so, how override these change image view's height , width?

is there simpler way storyboard?

thanks in advance.

you might want reevaluate constraints set in ib. make sure don't have width or height constraints, instead top/bottom/leading/trailing constraints. don't have programmatically. if must resize programmatically, create iboutlet references constraints in storyboard, , can adjust constant property of constraint. don't attempt change frame if you're using constraints.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
