ios - How to create custom uiview that button can be clicked inside uiview? -

i tried create clicked scrollview button (at bottom):

this code far:

scview = uiscrollview(frame: cgrect(x: 0, y: view.frame.maxy-110, width: view.bounds.width, height: 110))     self.view.addsubview(scview)      scview.backgroundcolor = uicolor.lightgray     scview.translatesautoresizingmaskintoconstraints = false      in 0 ... 10 {         let mynewview=uiview(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding), width: 200, height: 100))         mynewview.backgroundcolor=uicolor.white         mynewview.layer.cornerradius=10         self.scview.addsubview(mynewview)          let label = uilabel(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding)+5, width: 150, height: 10))         label.center = cgpoint(x: 160, y: 285)         label.textalignment = .left         label.text = "i'am title label"         label.textcolor = .black         mynewview.addsubview(label)          let ditancelabel = uilabel(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding)+5, width: 50, height: 10))         ditancelabel.center = cgpoint(x: 160, y: 285)         ditancelabel.textalignment = .right         ditancelabel.text = "0.04 km"         ditancelabel.textcolor = .red         mynewview.addsubview(ditancelabel)          let textview = uitextview(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding)+15, width: 200.0, height: 40.0))         self.automaticallyadjustsscrollviewinsets = false         textview.center = self.view.center         textview.textalignment = nstextalignment.justified         textview.textcolor = uicolor.lightgray         textview.backgroundcolor = uicolor.clear         mynewview.addsubview(textview)          let button = uibutton()         button.tag =         button.backgroundcolor = uicolor.white         button.settitle("\(i)", for: .normal)         button.settitlecolor(.black, for: .normal)         button.backgroundcolor = uicolor.clear         button.addtarget(self, action:#selector(handleregister(sender:)), for: .touchupinside)         button.frame = cgrect(x: xoffset, y: cgfloat(buttonpadding), width: 200, height: 100)         xoffset = xoffset + cgfloat(buttonpadding) + button.frame.size.width         mynewview.addsubview(button)     }      scview.contentsize = cgsize(width: xoffset, height: scview.frame.height) 

but code result this:

the first button can clicked, other cannot clicked. , 2 uilabels , 1 uitextview did not appear.

the handleregister method sender tag , print log know button can clicked or not.

how repair code can custom uiview in above image?

i need transfer label , textview text button click viewcontroller handle seque in handleregister.

1) can't see labels , other control because of container view size (200, 100)

 let mynewview=uiview(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding), width: 200, height: 100)) 

and set center of controls.

label.center = cgpoint(x: 160, y: 285)  ditancelabel.center = cgpoint(x: 160, y: 285) 

this center point not visible within container view. that's why can't see labels within view. just comment these line set center of labels , can see perfectly.

2) need transfer label , textview text button click viewcontroller handle seque in handleregister.

i hope have array in stored data display in custom view, find object array based on button tag, , pass object control.

3) first button can clicked, other cannot clicked.

again problem same labels. had set frame of button this

button.frame = cgrect(x: xoffset, y: cgfloat(buttonpadding), width: 200, height: 100) 

and increase xoffset line create view

xoffset = xoffset + cgfloat(buttonpadding) + button.frame.size.width 

xoffset increased each time size of button. if print xoffset value print (assuming initial value of xoffset = 10, padding = 0)

for in 0 ... 10 { print(xoffset) ..... other code  } 

output: 10, 210, 410, 610...... because of button out of bound container view , because of can't click on that.

i have updated code, check below

scview = uiscrollview(frame: cgrect(x: 0, y: view.frame.maxy-110, width: view.bounds.width, height: 110))     self.view.addsubview(scview)      scview.backgroundcolor = uicolor.lightgray     scview.translatesautoresizingmaskintoconstraints = false      in 0 ... 10 {         let mynewview=uiview(frame: cgrect(x: xoffset, y: cgfloat(buttonpadding), width: 200, height: 100))         mynewview.backgroundcolor=uicolor.white         mynewview.layer.cornerradius=10         self.scview.addsubview(mynewview)          let subvwoffset = 5          let label = uilabel(frame: cgrect(x: subvwoffset, y: cgfloat(buttonpadding)+5, width: 150, height: 10))         label.textalignment = .left         label.text = "i'am title label"         label.textcolor = .black         mynewview.addsubview(label)          let ditancelabel = uilabel(frame: cgrect(x: subvwoffset, y: cgfloat(buttonpadding)+5, width: 50, height: 10))         ditancelabel.textalignment = .right         ditancelabel.text = "0.04 km"         ditancelabel.textcolor = .red         mynewview.addsubview(ditancelabel)          let textview = uitextview(frame: cgrect(x: subvwoffset, y: cgfloat(buttonpadding)+15, width: 200.0, height: 40.0))         self.automaticallyadjustsscrollviewinsets = false         textview.center = self.view.center         textview.textalignment = nstextalignment.justified         textview.textcolor = uicolor.lightgray         textview.backgroundcolor = uicolor.clear         mynewview.addsubview(textview)          let button = uibutton()         button.tag =         button.backgroundcolor = uicolor.white         button.settitle("\(i)", for: .normal)         button.settitlecolor(.black, for: .normal)         button.backgroundcolor = uicolor.clear         button.addtarget(self, action:#selector(handleregister(sender:)), for: .touchupinside)         button.frame = cgrect(x: subvwoffset, y: cgfloat(buttonpadding), width: 200, height: 100)         xoffset = xoffset + cgfloat(buttonpadding) + button.frame.size.width         mynewview.addsubview(button)     }      scview.contentsize = cgsize(width: xoffset, height: scview.frame.height) 

let me know if find other difficulty.
