ios - How can I get my UICollectionView to be the same width as my device when using Auto Layout? -


i created uicollectionview in storyboard editor , added (custom) viewcontroller. every view controller in storyboard, says size 600x600 , uicollectionview, takes whole view, 600x600.

this not correct though, writing iphone app , real dimensions should 320x568!

because of this, when add items collection, placed off right side of screen. example, first add cell image in of size 160x213. left justified , takes left half of screen. when add next image, there huge gap , appears on left side, partly cut off. third image expect appear below first, doesn't appear @ all. believe off right side of screen. implies size of uicollectionview 600x600 , not 320x568.

i should mention i've tried think of fix this. example:

  • i tried adjusting size of collection view:

    self.photocollection.frame = cgrectmake(0, 0, 320, 568);

  • i tried unchecking "use size classes" in storyboard editor.

it seems work if uncheck "use auto layout" use auto layout. how work?

  1. you can set "simulated metrics" of view in storyboard below. personally, prefer using 3.5/4-inch construct layout, auto layout, need add constraints elements , ios automatically support 4.7 , 5 inch screen size.

  1. i think should google "auto layout" tutorials, , don't think hard pick :d. instance, if want set collection view frame equal view frame. can this

feel free ask follow question if have any, cheers!
