ios - AutoLayout complains about constraints for 2 UITextFields with no borders -


i trying build login view has 2 textfields, , 2 buttons. applying "add missing constraints" property xcode applies corresponding constraints elements in loginviewcontroller in storyboard. restricting app run in portrait mode, using "wcompact hregular" setup.

whenever run app , transition loginviewcontroller segue, app displays 1 textfield, , shows bunch of errors in console regarding autolayout.

the functionality trying achieve come login screen resembles new parse login screen. having 2 textfields no borders , bottom border of username textfield showing can divide password textfield, so:

does know how fix , why not work? tried manually adding constraints manually, did not work. also, if give textfields rounded borders , make them little smaller storyboard's full width, it's expected do.

thank you in advance.

cheers!

"add missing constraints" not idea add constraints..rather should prefer add constraints manually...

here image ui...i used wanyhany layout practice add constraints universal devices...

enter image description here

i used width constraint textfield, rather should equal width super view , add multiplier resize width according device width

here output image in different sizes...
