iphone - Custom View size in iOS not dynamic -


i have started first app on ios week ago. have created custom view use in app using appledeveloperwebsite custom rating control tutorial.

now have chosen iphone7 device in storyboard , run on iphone 7 emulator works when run on iphone 5 emulator (size of screen changes) custom views extend beyond screen. other controls sizes resize set constraints custom view sizes messed up.

please help

import uikit  @ibdesignable class xradiobuttonview: uiview { var button: uibutton! var label: uilabel!  @ibinspectable var text: string? {     didset{         label.text = text     } }  //properties var isselected = 0  //initialization override init(frame: cgrect){     super.init(frame: frame)     addsubviews() }  required init(coder adecoder: nscoder) {     super.init(coder: adecoder)!     addsubviews() }  func addsubviews() {     self.backgroundcolor = uicolor.white      let xwidth = bounds.size.width     let xheight = bounds.size.height      let tap = uitapgesturerecognizer(target: self, action: #selector(xradiobuttonview.radiobuttontexttapped))      button = uibutton(frame: cgrect(x: 1, y: 1, width: xwidth - 2, height: xheight - 4))     button.backgroundcolor = uicolor.white     button.addtarget(self, action: #selector(xradiobuttonview.radiobuttontapped(button:)), for: .touchdown)      addsubview(button)      label = uilabel(frame: cgrect(x: 1, y: 1, width: xwidth - 2, height: xheight - 2))     label.textcolor = uicolor.init(hex: "#d5d5d5")     //label.font = uifont.init(name: label.font.fontname, size: 25)     //label.font = label.font.withsize(25)     label.font = uifont.boldsystemfont(ofsize: 25)     label.textalignment = nstextalignment.center     label.isuserinteractionenabled = true     label.addgesturerecognizer(tap)      addsubview(label) }  override func layoutsubviews() {     // set button's width , height square size of frame's height.  }  override func prepareforinterfacebuilder() {     super.prepareforinterfacebuilder()     label.text = "xrbv" }  func radiobuttontapped(button: uibutton) {     if isselected == 0 {         isselected = 1         self.backgroundcolor = uicolor.init(hex: "#00bfa5")         label.textcolor = uicolor.init(hex: "#00bfa5")     } else {         isselected = 0         self.backgroundcolor = uicolor.white         label.textcolor = uicolor.init(hex: "#d5d5d5")     } }  func radiobuttontexttapped(sender: uitapgesturerecognizer){     if isselected == 0 {         isselected = 1         self.backgroundcolor = uicolor.init(hex: "#00bfa5")         label.textcolor = uicolor.init(hex: "#00bfa5")     } else {         isselected = 0         self.backgroundcolor = uicolor.white         label.textcolor = uicolor.init(hex: "#d5d5d5")     } } }

can see pg button should finish green color finishes white color button extended beyond screen

you either need set frame in layoutsubviews or need implement autolayout in code:

    button = uibutton(frame: cgrect(x: 1, y: 1, width: xwidth - 2, height: xheight - 4))     button.backgroundcolor = uicolor.white     button.addtarget(self, action: #selector(xradiobuttonview.radiobuttontapped(button:)), for: .touchdown)     addsubview(button)     button.translatesautoresizingmaskintoconstraints = false     let attributes: [nslayoutattribute] = [.top, .bottom, .leading, .trailing]     let constants = [2, 2, 10, 10]  // 2 top , bottom, 10 leading , trailing     nslayoutconstraint.activate(attributes.enumerated().map { nslayoutconstraint(item: button, attribute: $1, relatedby: .equal, toitem: button.superview, attribute: $1, multiplier: 1, constant: constants[$0]) })

the example uses old way because constraints uniform, if have more complicated simpler use nslayoutanchor of ios 9.

edit: here code tuples if interested:

    button.translatesautoresizingmaskintoconstraints = false     let attributes: [(nslayoutattribute, cgfloat)] = [(.top, 2), (.bottom, 2), (.leading, 12), (.trailing, 12)]     nslayoutconstraint.activate(attributes.map { nslayoutconstraint(item: button, attribute: $0.0, relatedby: .equal, toitem: button.superview, attribute: $0.0, multiplier: 1, constant: $0.1) })
