यहाँ टार्गेटेशन केUIButton
साथ प्रोग्रामेटिक रूप से जोड़ने का पूरा समाधान है । स्विफ्ट 2.2
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
button.backgroundColor = .greenColor()
button.setTitle("Test Button", forState: .Normal)
button.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside)
self.view.addSubview(button)
}
func buttonAction(sender: UIButton!) {
print("Button tapped")
}
प्रत्येक iPhone स्क्रीन के लिए बटन को सही ढंग NSLayoutConstraint
से frame
रखने के बजाय इसका उपयोग करना बेहतर है ।
अद्यतन स्विफ्ट 3.1 का कोड :
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
button.backgroundColor = .green
button.setTitle("Test Button", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
}
func buttonAction(sender: UIButton!) {
print("Button tapped")
}
स्विफ्ट 4.2 को अपडेट किया गया कोड :
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
button.backgroundColor = .green
button.setTitle("Test Button", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
}
@objc func buttonAction(sender: UIButton!) {
print("Button tapped")
}
यदि func buttonAction
घोषित है private
या internal
।
आप UIButton, UIlable और UITextfield को इस तरह से प्रोग्रामेटिक रूप से जोड़ सकते हैं।
UIButton कोड
// var button = UIButton.buttonWithType(UIButtonType.System) as UIButton
let button = UIButton(type: .System) // let preferred over var here
button.frame = CGRectMake(100, 100, 100, 50)
button.backgroundColor = UIColor.greenColor()
button.setTitle("Button", forState: UIControlState.Normal)
button.addTarget(self, action: "Action:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(button)
उइलाबेल कोड
var label: UILabel = UILabel()
label.frame = CGRectMake(50, 50, 200, 21)
label.backgroundColor = UIColor.blackColor()
label.textColor = UIColor.whiteColor()
label.textAlignment = NSTextAlignment.Center
label.text = "test label"
self.view.addSubview(label)
UITextField कोड
var txtField: UITextField = UITextField()
txtField.frame = CGRectMake(50, 70, 200, 30)
txtField.backgroundColor = UIColor.grayColor()
self.view.addSubview(txtField)
आशा है कि यह आपके लिए उपयोगी है।
स्विफ्ट 3 के लिए
let button = UIButton()
button.frame = CGRect(x: self.view.frame.size.width - 60, y: 60, width: 50, height: 50)
button.backgroundColor = UIColor.red
button.setTitle("your Button Name", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
func buttonAction(sender: UIButton!) {
print("Button tapped")
}
स्विफ्ट 4 के लिए
let button = UIButton()
button.frame = CGRect(x: self.view.frame.size.width - 60, y: 60, width: 50, height: 50)
button.backgroundColor = UIColor.red
button.setTitle("Name your Button ", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
@objc func buttonAction(sender: UIButton!) {
print("Button tapped")
}
button.frame = (frame: CGRect(x: self.view.frame.size.width - 60, y: 20, width: 50, height: 50))
होना चाहिएbutton.frame = CGRect(x: self.view.frame.size.width - 60, y: 20, width: 50, height: 50)
स्विफ्ट 3
let btn = UIButton(type: .custom) as UIButton
btn.backgroundColor = .blue
btn.setTitle("Button", for: .normal)
btn.frame = CGRect(x: 100, y: 100, width: 200, height: 100)
btn.addTarget(self, action: #selector(clickMe), for: .touchUpInside)
self.view.addSubview(btn)
func clickMe(sender:UIButton!) {
print("Button Clicked")
}

स्विफ्ट 3.0 का उपयोग करके यह कैसे करें ।
func createButton() {
let button = UIButton(type: .system)
button.frame = CGRect(x: 100.0, y: 100.0, width: 100.0, height: 100.0)
button.setTitle(NSLocalizedString("Button", comment: "Button"), for: .normal)
button.backgroundColor = .green
button.addTarget(self, action: #selector(buttonAction(sender:)), for: .touchUpInside)
view.addSubview(button)
}
@objc func buttonAction(sender: UIButton) {
print("Button pushed")
}
var sampleButton:UIButton?
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(animated: Bool) {
sampleButton = UIButton(type: .RoundedRect)
//sampleButton.frame = CGRect(x:50, y:500, width:70, height:50)
sampleButton!.setTitle("Sample \n UI Button", forState: .Normal)
sampleButton!.titleLabel?.lineBreakMode = .ByWordWrapping
sampleButton!.titleLabel?.textAlignment = .Center
sampleButton!.setTitleColor(UIColor.whiteColor(), forState: .Normal)
sampleButton!.layer.cornerRadius = 6
sampleButton!.backgroundColor = UIColor.redColor().colorWithAlphaComponent(0.6)
sampleButton?.tintColor = UIColor.brownColor()
//Add padding around text
sampleButton!.titleEdgeInsets = UIEdgeInsetsMake(-10,-10,-10,-10)
sampleButton!.contentEdgeInsets = UIEdgeInsetsMake(5,5,5,5)
//Action set up
sampleButton!.addTarget(self, action: "sampleButtonClicked", forControlEvents: .TouchUpInside)
self.view.addSubview(sampleButton!)
//Button Constraints:
sampleButton!.translatesAutoresizingMaskIntoConstraints = false
//To anchor above the tab bar on the bottom of the screen:
let bottomButtonConstraint = sampleButton!.bottomAnchor.constraintEqualToAnchor(bottomLayoutGuide.topAnchor, constant: -20)
//edge of the screen in InterfaceBuilder:
let margins = view.layoutMarginsGuide
let leadingButtonConstraint = sampleButton!.leadingAnchor.constraintEqualToAnchor(margins.leadingAnchor)
bottomButtonConstraint.active = true
leadingButtonConstraint.active = true
}
func sampleButtonClicked(){
print("sample Button Clicked")
}
एपीआई नहीं बदला है - केवल वाक्य रचना है। आप UIButton
इसे इस तरह से बना और जोड़ सकते हैं :
var button = UIButton(frame: CGRectMake(0, 0, 50, 50))
self.view.addSubview(button) // assuming you're in a view controller
आप इस तरह बना सकते हैं और आप इस तरह कार्रवाई भी जोड़ सकते हैं ...।
import UIKit
let myButton = UIButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!)
{ super.init(nibName: nibName, bundle: nibBundle)
myButton.targetForAction("tappedButton:", withSender: self)
}
func tappedButton(sender: UIButton!)
{
println("tapped button")
}
इस कोड को viewDidLoad में
जोड़ें // बटन जोड़ें
var button=UIButton(frame: CGRectMake(150, 240, 75, 30))
button.setTitle("Next", forState: UIControlState.Normal)
button.addTarget(self, action: "buttonTapAction:", forControlEvents: UIControlEvents.TouchUpInside)
button.backgroundColor = UIColor.greenColor()
self.view.addSubview(button)
इस फ़ंक्शन को इसके बाहर लिखें, जब आप बटन पर टैप करेंगे तो यह कॉल करेगा
func buttonTapAction(sender:UIButton!)
{
println("Button is working")
}
स्विफ्ट 2 और आईओएस 9.2.1 में
var button: UIButton = UIButton(type: UIButtonType.Custom) as UIButton
self.button.frame = CGRectMake(130, 70, 60, 20)
self.button.setTitle("custom button", forState: UIControlState.Normal)
self.button.addTarget(self, action:"buttonActionFuncName", forControlEvents: UIControlEvents.TouchUpInside)
self.button.setTitleColor(UIColor.blackColor(), forState: .Normal)
self.button.layer.borderColor = UIColor.blackColor().CGColor
self.button.titleLabel?.font = UIFont(name: "Helvetica-Bold", size: 13)
self.view.addSubview(self.button)
स्विफ्ट 5 के लिए स्विफ्ट 4 के समान ही है
let button = UIButton()
button.frame = CGRect(x: self.view.frame.size.width - 60, y: 60, width: 50, height: 50)
button.backgroundColor = UIColor.red
button.setTitle("Name your Button ", for: .normal)
button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
self.view.addSubview(button)
@objc func buttonAction(sender: UIButton!) {
print("Button tapped")
}
स्टोरीबोर्ड से UIButton बनाने के लिए: 1 - ऑब्जेक्ट लाइब्रेरी से UIButton ऑब्जेक्ट को स्टोरीबोर्ड फ़ाइल में ViewController पर खींचें 2 - सहायक संपादक 3 दिखाएं - UIButton से दायाँ क्लिक के साथ खींचें अपनी कक्षा में ऊपर बनाएं। परिणाम निम्नलिखित है:
@IBAction func buttonActionFromStoryboard(sender: UIButton)
{
println("Button Action From Storyboard")
}
UIButton प्रोग्रामेटिक रूप से बनाने के लिए: 1- "ओवरराइड फंक व्यूडीडलॉड ()" में लिखें:
let uiButton = UIButton.buttonWithType(UIButtonType.System) as UIButton
uiButton.frame = CGRectMake(16, 116, 288, 30)
uiButton.setTitle("Second", forState: UIControlState.Normal);
uiButton.addTarget(self, action: "buttonActionFromCode:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(uiButton)
2- IBAction func जोड़ें:
@IBAction func buttonActionFromCode(sender:UIButton)
{
println("Button Action From Code")
}
let myFirstButton = UIButton()
myFirstButton.setTitle("Software Button", forState: .Normal)
myFirstButton.setTitleColor(UIColor.redColor(), forState: .Normal)
myFirstButton.frame = CGRectMake(100, 300, 150, 50)
myFirstButton.backgroundColor = UIColor.purpleColor()
myFirstButton.layer.cornerRadius = 14
myFirstButton.addTarget(self, action: "pressed:", forControlEvents: .TouchUpInside)
self.view.addSubview(myFirstButton)
myFirstButton.hidden=true
nameText.delegate = self
func pressed(sender: UIButton!) {
var alertView = UIAlertView()
alertView.addButtonWithTitle("Ok")
alertView.title = "title"
alertView.message = "message"
alertView.show();
}
सिम्युलेटर में हाँ। कुछ बार यह चयनकर्ता को पहचानता है कि ऐसा लगता है कि एक बग है। यहां तक कि मैंने आपके कोड के लिए सामना नहीं किया, फिर मैंने सिर्फ एक्शन नाम (चयनकर्ता) बदल दिया। यह काम करता हैं
let buttonPuzzle:UIButton = UIButton(frame: CGRectMake(100, 400, 100, 50))
buttonPuzzle.backgroundColor = UIColor.greenColor()
buttonPuzzle.setTitle("Puzzle", forState: UIControlState.Normal)
buttonPuzzle.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
buttonPuzzle.tag = 22;
self.view.addSubview(buttonPuzzle)
चयनकर्ता कार्य यहाँ है:
func buttonAction(sender:UIButton!)
{
var btnsendtag:UIButton = sender
if btnsendtag.tag == 22 {
//println("Button tapped tag 22")
}
}
यह मेरे लिए बहुत अच्छी तरह से काम करता है, # डायनेमिकबटनटन #IOS #Swift #Xcode
func setupButtonMap(){
let mapButton = UIButton(type: .system)
mapButton.setImage(#imageLiteral(resourceName: "CreateTrip").withRenderingMode(.alwaysOriginal), for: .normal)
mapButton.frame = CGRect(x: 0, y: 0, width: 34, height: 34)
mapButton.contentMode = .scaleAspectFit
mapButton.backgroundColor = UIColor.clear
mapButton.addTarget(self, action: #selector(ViewController.btnOpenMap(_:)), for: .touchUpInside)
navigationItem.leftBarButtonItem = UIBarButtonItem(customView: mapButton)
}
@IBAction func btnOpenMap(_ sender: Any?) {
print("Successful")
}
प्रोग्राम बटन को जोड़ने के लिए Swift 4.2 में यह नमूना कोड लिखें।
override func viewDidLoad() {
super.viewDidLoad()
let myButton = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
myButton.backgroundColor = .green
myButton.setTitle("Hello UIButton", for: .normal)
myButton.addTarget(self, action: #selector(myButtonAction), for: .touchUpInside)
self.view.addSubview(myButton)
}
@objc func myButtonAction(sender: UIButton!) {
print("My Button tapped")
}
// UILabel:
let label = UILabel()
label.frame = CGRectMake(35, 100, 250, 30)
label.textColor = UIColor.blackColor()
label.textAlignment = NSTextAlignment.Center
label.text = "Hello World"
self.view.addSubview(label)
// UIButton:
let btn: UIButton = UIButton(type: UIButtonType.Custom) as UIButton
btn.frame = CGRectMake(130, 70, 60, 20)
btn.setTitle("Click", forState: UIControlState.Normal)
btn.setTitleColor(UIColor.blackColor(), forState: .Normal)
btn.addTarget(self, action:Selector("clickAction"), forControlEvents: UIControlEvents.TouchUpInside)
view.addSubview(btn)
// Button Action:
@IBAction func clickAction(sender:AnyObject)
{
print("Click Action")
}
चरण 1: एक नया प्रोजेक्ट बनाएं
चरण 2: ViewController.swift में
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// CODE
let btn = UIButton(type: UIButtonType.System) as UIButton
btn.backgroundColor = UIColor.blueColor()
btn.setTitle("CALL TPT AGENT", forState: UIControlState.Normal)
btn.frame = CGRectMake(100, 100, 200, 100)
btn.addTarget(self, action: "clickMe:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btn)
}
func clickMe(sender:UIButton!) {
print("CALL")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
