UIScrollView, UITextField, NSNotificationCenter, UITapGestureRecognizer, PassData
In storyboard click on wCompact hCompact
Select Top Left side first four Block
Add ScrollView X = 0, Y = 0, 600*600 and add below pin
Add UIView X = 0, Y = 0, 600*600 and set below pin
Control + click Drag and drop View to ScrollView Add below constraints
Add view on First view X = 0, Y = 0, 600*50 and add below pin
Control + click Drag and drop view to first view select equal height constraints
go to show size inspector click on Equal Height double click on that
add multiplier 50/600
Add view on First view X = 0, Y = 50, 600*500 and add below pin
Control + click Drag and drop view to first view select equal height constraints
go to show size inspector click on Equal Height double click on that
add multiplier 500/600
Add view on First view X = 0, Y = 550, 600*50 and add below pin
View Differanceat with top view, middle view and bottom view for batter understanding
add label (horizontally centre and vertically centre) on top view with text Sign Up
Control + click Drag and drop label to view and set below constraints
Add one view on middle view X = centre horizontally, Y = 0, 50*50
Control + click Drag and drop inside view and select Aspect Ratio
Control + click Drag and drop view to Middle view add below Constraints
go to show size inspector click on Equal Height double click on that
add multiplier 50/500
Add pin on top with middle view
Add one UITextField X = centre horizontally, Y = 50, 400*40
Add below pin with (in middle) first view
Control + click Drag and drop textfield to Middle view add below Constraints
go to show size inspector click on Equal Width double click on that
add multiplier 400/600
go to show size inspector click on Equal Height double click on that
add multiplier 40/500
Add view X = centre horizontally, Y= 90, 50*50 below textfield
Add below pin with (in middle view) first textfield
Control + click Drag and drop view to (in middle view) first view add below Constraints
Add one UITextField X = centre horizontally, Y = 140, 400*40
Add below pin with (in middle) Second view
Control + click Drag and drop Textfield to (in middle view) first textfield add below constraints
Now add another view and set pin and constraints like (in middle view) Second view
then add another textfield and set pin and constraints like (in middle view) Second textfield
if you change first view height or width it will automatically effect to all view
if you change first textfield height or width it will automatically effect to all textfield
adjust all view and textfield (last view to bottom view distance should be zero ro else set whatever need)
last view set bottom constraints to middle view
remove constraints which is not highlight
bottom view add view X = centre horizontally, Y = Centre vertically, 200*50 inside bottom view (because want to set first button on X = 1/4 and second button Y = (1/4)*3 if button width == 100 ) and add below Constraints
go to show size inspector click on Equal Width double click on that
add multiplier 200/600
Add submit button X = 100, Y = centre vertically in bottom view, 100*30
Add below pin to button
Control + click Drag and drop button to (in bottom view) view and add below constraints
go to show size inspector click on Equal Width double click on that
add multiplier 100/600
go to show size inspector click on Equal Height double click on that
add multiplier 30/50
Add Cancel button X = 400, Y = centre vertically in bottom view, 100*30
Add below pin to button
Control + click Drag and drop cancel button to submit button and add below Constraints
Set Place holder First Name, Last Name, Phone Number, City
Set tag for all TextField
Set delegate for all Textfield
