According to https://developer.dji.com/api-reference/ios-uilib-api/Widgets/PreFlightStatusWidget.html:
"Tapping on status text will toggle between show and hide DUXPreflightChecklistController."
When I tap on the status text in the widget, the DUXPreflightChecklistController is not shown. Also, if I manually show the DUXPreflightChecklistController, there is a close button in the top right corner of the panel but tapping it does not hide the panel.
What is the proper way to configure this panel?
I'm using DJISDK 4.7.1 and DJIUXSDK 4.7.1 with Swift and iOS 12/xCode 10.0.
To provide a bit more detail, I do not want to use the Default Layout but I am using DUXStatusBarViewController. That is embedded in a UIView across the top of my app. I cannot find any properties for that controller that would allow me to hook it up to my instance of DUXPreflightChecklistController, which is also embedded in a UIView.
For: DUXPreflightChecklistController
I'd just solved that
var preflightChecklistController: DUXPreflightChecklistController!
weak var preFlightTableView: UITableView!
private var compassItemIndex: Int = -1
private var storageItemIndex: Int = -1
override func viewDidLoad() {
super.viewDidLoad()
preflightChecklistController = DUXPreflightChecklistController()
addChild(preflightChecklistController)
}
func renderChecklist() {
if let checklistVC = preflightChecklistController {
for subview in checklistVC.view.subviews {
if subview.isKind(of: UITableView.self) {
if let tableView = subview as? UITableView {
self.view.addSubview(tableView)
preFlightTableView = tableView
}
}
}
guard let checklistManager = checklistVC.checklistManager else { return }
let itemList = checklistManager.preFlightChecklistItems
for (index, item) in itemList.enumerated() {
if let _ = item as? DUXStorageCapacityChecklistItem {
storageItemIndex = index
}
if let _ = item as? DUXCompassChecklistItem {
compassItemIndex = index
}
}
preFlightTableView.reloadData()
checklistManager.startCheckingList()
}
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
renderChecklist()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
guard preFlightTableView != nil else { return }
if let compassCell = preFlightTableView.cellForRow(at: IndexPath(item: compassItemIndex, section: 0)) {
for view in compassCell.subviews {
if let button = view as? UIButton, button.titleLabel?.text == "Calibrate" {
button.addTarget(self, action: #selector(doActionForSpecifiedBTN(sender:)), for: .touchUpInside)
break
}
}
}
if let storageCell = preFlightTableView.cellForRow(at: IndexPath(item: storageItemIndex, section: 0)) {
for view in storageCell.subviews {
if let button = view as? UIButton, button.titleLabel?.text == "Format" {
button.addTarget(self, action: #selector(doActionForSpecifiedBTN(sender:)), for: .touchUpInside)
break
}
}
}
}
#objc func doActionForSpecifiedBTN(sender: UIButton) {
guard let btnTitle = sender.titleLabel else { return }
switch btnTitle.text {
case "Calibrate":
// your func goes here
case "Format":
// your func goes here
default:
break
}
}
i have a button that when selected, a white box appears over the title text of the button. I dont want this white box to appear. See images.
button state unselected
button state selected
If i remove the if statement and have the button so it can only be selected but not deselected, on selection, this white box doesn't appear. The code controlling this is below...
#IBAction func backButtonPressed(_ sender: Any) {
if let button = sender as? UIButton {
if button.isSelected {
createWorkoutButton.isEnabled = false
backButton.backgroundColor = #colorLiteral
backButtonPressed = false
backButton.isSelected = false
} else {
createWorkoutButton.isEnabled = true
backButton.backgroundColor = #colorLiteral
backButtonPressed = true
backButton.isSelected = true
}
}
}
Just found a solution. Add this line of code -
button.tintColor = .clear
Now -
#IBAction func backButtonPressed(_ sender: Any) {
if let button = sender as? UIButton {
if button.isSelected {
createWorkoutButton.isEnabled = false
backButton.backgroundColor = #colorLiteral
backButtonPressed = false
backButton.isSelected = false
button.tintColor = .clear // Add this line of code
} else {
createWorkoutButton.isEnabled = true
backButton.backgroundColor = #colorLiteral
backButtonPressed = true
backButton.isSelected = true
button.tintColor = .clear
}
}
}
In story board use button type custom.
I currently have a UITextfield with an eye icon in it that when pressed is supposed to toggle the secure text entry on and off.
I know you can check mark the "secure text entry" box in the attributes inspector but how to do it so it toggles whenever the icon is pressed?
Use this code,
iconClick is bool variable, or you need other condition check it,
var iconClick = true
eye Action method:
#IBAction func iconAction(sender: AnyObject) {
if iconClick {
passwordTF.secureTextEntry = false
} else {
passwordTF.secureTextEntry = true
}
iconClick = !iconClick
}
hope its helpful
An unintended side-effect of this is that if the user toggles to insecure, and then back to secure, the existing text will be cleared if the user continues typing. The cursor may also end up in the wrong position unless we reset the selected text range.
Below is an implementation that handles these cases (Swift 4)
extension UITextField {
func togglePasswordVisibility() {
isSecureTextEntry = !isSecureTextEntry
if let existingText = text, isSecureTextEntry {
/* When toggling to secure text, all text will be purged if the user
continues typing unless we intervene. This is prevented by first
deleting the existing text and then recovering the original text. */
deleteBackward()
if let textRange = textRange(from: beginningOfDocument, to: endOfDocument) {
replace(textRange, withText: existingText)
}
}
/* Reset the selected text range since the cursor can end up in the wrong
position after a toggle because the text might vary in width */
if let existingSelectedTextRange = selectedTextRange {
selectedTextRange = nil
selectedTextRange = existingSelectedTextRange
}
}
}
This snippet is using the replace(_:withText:) function because it triggers the .editingChanged event, which happens to be useful in my application. Just setting text = existingText should be fine as well.
Why to use an extra var. In the action method of the eye button just do as below
password.secureTextEntry = !password.secureTextEntry
UPDATE
Swift 4.2 (as per #ROC comment)
password.isSecureTextEntry.toggle()
I wrote extension for the same. To provide Password toggle.
In your Assets first add images that you want for toggle.
Add following extension for UITextField.
extension UITextField {
fileprivate func setPasswordToggleImage(_ button: UIButton) {
if(isSecureTextEntry){
button.setImage(UIImage(named: "ic_password_visible"), for: .normal)
}else{
button.setImage(UIImage(named: "ic_password_invisible"), for: .normal)
}
}
func enablePasswordToggle(){
let button = UIButton(type: .custom)
setPasswordToggleImage(button)
button.imageEdgeInsets = UIEdgeInsets(top: 0, left: -16, bottom: 0, right: 0)
button.frame = CGRect(x: CGFloat(self.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
button.addTarget(self, action: #selector(self.togglePasswordView), for: .touchUpInside)
self.rightView = button
self.rightViewMode = .always
}
#IBAction func togglePasswordView(_ sender: Any) {
self.isSecureTextEntry = !self.isSecureTextEntry
setPasswordToggleImage(sender as! UIButton)
}
}
Call extension on your UITextField Outlet
override func viewDidLoad() {
super.viewDidLoad()
txtPassword.enablePasswordToggle()
txtConfirmPassword.enablePasswordToggle()
}
Swift 4 solution
You don't need extra if statement for simple toggle isSecureTextEntry property
func togglePasswordVisibility() {
password.isSecureTextEntry = !password.isSecureTextEntry
}
But there is a problem when you toggle isSecureTextEntry UITextField doesn't recalculate text width and we have extra space to the right of the text. To avoid this you should replace text this way
func togglePasswordVisibility() {
password.isSecureTextEntry = !password.isSecureTextEntry
if let textRange = password.textRange(from: password.beginningOfDocument, to: password.endOfDocument) {
password.replace(textRange, withText: password.text!)
}
}
UPDATE
Swift 4.2
Instead of
password.isSecureTextEntry = !password.isSecureTextEntry
you can do this
password.isSecureTextEntry.toggle()
Use UITextFiled rightView to show toggle button
var rightButton = UIButton(type: .custom)
rightButton.frame = CGRect(x:0, y:0, width:30, height:30)
yourtextfield.rightViewMode = .always
yourtextfield.rightView = rightButton
If you need TextField with similar feature in multiple places its best to subclass the UITextField like follwing example -
import UIKit
class UIShowHideTextField: UITextField {
let rightButton = UIButton(type: .custom)
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
commonInit()
}
required override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
func commonInit() {
rightButton.setImage(UIImage(named: "password_show") , for: .normal)
rightButton.addTarget(self, action: #selector(toggleShowHide), for: .touchUpInside)
rightButton.frame = CGRect(x:0, y:0, width:30, height:30)
rightViewMode = .always
rightView = rightButton
isSecureTextEntry = true
}
#objc
func toggleShowHide(button: UIButton) {
toggle()
}
func toggle() {
isSecureTextEntry = !isSecureTextEntry
if isSecureTextEntry {
rightButton.setImage(UIImage(named: "password_show") , for: .normal)
} else {
rightButton.setImage(UIImage(named: "password_hide") , for: .normal)
}
}
}
After which you can use it in any ViewController,
class ViewController: UIViewController {
#IBOutlet var textField: UIShowHideTextField!
override func viewDidLoad() {
super.viewDidLoad()
textField.becomeFirstResponder()
}
}
For Objective c
set image for RightButton In viewdidload Method
[RightButton setImage:[UIImage imageNamed:#"iconEyesOpen"] forState:UIControlStateNormal];
[RightButton setImage:[UIImage imageNamed:#"iconEyesClose"] forState:UIControlStateSelected];
and then set action method for that RightButton
-(IBAction)RightButton:(id)sender
{
if (_rightButton.selected)
{
_rightButton.selected = NO;
_passwordText.secureTextEntry = YES;
if (_passwordText.isFirstResponder) {
[_passwordText resignFirstResponder];
[_passwordText becomeFirstResponder];
}
}
else
{
_rightButton.selected = YES;
_passwordText.secureTextEntry = NO;
if (_passwordText.isFirstResponder) {
[_passwordText resignFirstResponder];
[_passwordText becomeFirstResponder];
}
}
}
Swift 3
// MARK: Btn EyeAction
#IBAction func btnEyeAction(_ sender: Any) {
if(iconClick == true) {
txtPassword.isSecureTextEntry = false
iconClick = false
} else {
txtPassword.isSecureTextEntry = true
iconClick = true
}
}
Shortest!
I think this is the shortest solution for secure entry as well as updating the picture of the button.
#IBAction func toggleSecureEntry(_ sender: UIButton) {
sender.isSelected = !sender.isSelected
textfieldPassword.isSecureTextEntry = !sender.isSelected
}
Assign the show/hide picture of the button according to the state selected /default , no need to create any variable or outlet.
This worked for me on Swift 5.0
#IBAction func changePasswordVisibility(_ sender: UIButton) {
passwordField.isSecureTextEntry.toggle()
if passwordField.isSecureTextEntry {
if let image = UIImage(systemName: "eye.fill") {
sender.setImage(image, for: .normal)
}
} else {
if let image = UIImage(systemName: "eye.slash.fill") {
sender.setImage(image, for: .normal)
}
}
}
Button attributes:
Result:
Swift 3
passwordTF.isSecureTextEntry = true
passwordTF.isSecureTextEntry = false
#IBAction func eye_toggle_clicked(sender: AnyObject)
{
if toggleBtn.tag == 0
{
passwordTxt.secureTextEntry=true
toggleBtn.tag=1
}
else
{
passwordTxt.secureTextEntry=false
toggleBtn.tag=0
}
}
As others have noted, the property is secureTextEntry, but you won't find this in the UITextField documentation, as it is actually inherited by a UITextField through the UITextInputTraits protocol- https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITextInputTraits_Protocol/#//apple_ref/occ/intfp/UITextInputTraits/secureTextEntry
You can simply toggle this value each time your button is tapped:
#IBAction func togglePasswordSecurity(sender: UIButton) {
self.passwordField.secureTextEntry = !self.passwordField.secureTextEntry
}
try this line:
#IBAction func btnClick(sender: AnyObject) {
let btn : UIButton = sender as! UIButton
if btn.tag == 0{
btn.tag = 1
textFieldSecure.secureTextEntry = NO
}
else{
btn.tag = 0
textFieldSecure.secureTextEntry = NO;
}
}
Here is your answer no need to take any bool var:
#IBAction func showHideAction(sender: AnyObject) {
if tfPassword.secureTextEntry{
tfPassword.secureTextEntry = false
}else{
tfPassword.secureTextEntry = true;
}
}
First you need to set image(visible or hide) of button of eye for different state (selected or normal)
than connect IBAction and write code like
#IBAction func btnPasswordVisiblityClicked(_ sender: Any) {
(sender as! UIButton).isSelected = !(sender as! UIButton).isSelected
if (sender as! UIButton).isSelected {
txtfPassword.isSecureTextEntry = false
} else {
txtfPassword.isSecureTextEntry = true
}
}
In Swift 4
var iconClick : Bool!
override func viewDidLoad() {
super.viewDidLoad()
iconClick = true
}
#IBAction func showHideAction(_ sender: Any)
{
let userPassword = userPasswordTextFiled.text!;
if(iconClick == true) {
userPasswordTextFiled.isSecureTextEntry = false
iconClick = false
} else {
userPasswordTextFiled.isSecureTextEntry = true
iconClick = true
}
}
Assignment values change from YES/NO to true/false boolean values.
password.secureTextEntry = true //Visible
password.secureTextEntry = false //InVisible
You can try this code..
i think it's helpful.
Use button with eye image
and make buttonHandler method
set Tag for button with value 1
-(IBAction) buttonHandlerSecureText:(UIButton *)sender{
if(sender.tag ==1){
[self.textField setSecureTextEntry:NO];
sender.tag = 2;
}
else{
[self.textField setSecureTextEntry:YES];
sender.tag = 1;
}
}
For Xamarin folks:
passwordField.SecureTextEntry = passwordField.SecureTextEntry ? passwordField.SecureTextEntry = false : passwordField.SecureTextEntry = true;
Try this code in swift 4, tried to make a reusable code within a controller. I have set different image for buttons in storyboard as shown in the link https://stackoverflow.com/a/47669422/8334818
#IBAction func clickedShowPassword(_ sender: UIButton) {
var textField :UITextField? = nil
print("btn ",sender.isSelected.description)
switch sender {
case encryptOldPswdBtn:
encryptOldPswdBtn.isSelected = !encryptOldPswdBtn.isSelected
textField = oldPasswordTextField
default:
break
}
print("text ",textField?.isSecureTextEntry.description)
textField?.isSecureTextEntry = !(textField?.isSecureTextEntry ?? false)
}
#objc func togglePasscode(){
switch textfield.isSecureTextEntry{
case true:
textfield.isSecureTextEntry = false
case false:
textfield.isSecureTextEntry = true
}
}
Here is a easy and more readable solution using Switch statement.
Hope this is simpler solution rather than creating a BOOL object globally.
#IBAction func passwordToggleButton(sender: UIButton) {
let isSecureTextEntry = passwordTextField.isSecureTextEntry
passwordTextField.isSecureTextEntry = isSecureTextEntry ? false : true
if isSecureTextEntry {
visibilityButton.setImage(UIImage(named: "visibility"), for: .normal)
} else {
visibilityButton.setImage(UIImage(named: "visibility_off"), for: .normal)
}
}
only add this line into your code replace you TextField name with "textfield" Done:
you need to change the isSecureTextEntry propertity to change true for password type textFiled like ......
textField.isSecureTextEntry = true
sender.isSelected = !sender.isSelected
if(sender.isSelected == true) {
RegPasswordField.isSecureTextEntry = false
sender.setBackgroundImage(UIImage(systemName: "eye.fill"), for: .normal)
} else {
RegPasswordField.isSecureTextEntry = true
sender.setBackgroundImage(UIImage(systemName: "eye"), for: .normal)
}
Swift 5 Please use this
var btnClick = true
if(btnClick == true) {
passwordTextField.isSecureTextEntry = false
} else {
passwordTextField.isSecureTextEntry = true
}
btnClick = !btnClick
}
var viewingPassword = true
#IBAction func btnEyeAction(_ sender: Any) {
passwordTF.isSecureTextEntry = viewingPassword ? false : true
viewingPassword.toggle()
}
I make simple player with VK Api. I want to do this.
When I clicked first track and then second change first button title "stop" to "play" automatically.
How to do it?
My play/stop button action.
func playAction(sender: UIButton!) {
if sender.currentTitle == "P" {
let track = dataOfTracks[sender.tag] as trackDoc
let url = NSURL(string: track.data.url)
player = AVPlayer(URL: url!)
player.play()
sender.setTitle("S", forState: UIControlState.Normal)
} else if sender.currentTitle == "S" {
sender.setTitle("P", forState: UIControlState.Normal)
player.pause()
}
}
EDIT CODE DETAILS:
don't reallocate every time the button. It must be another outlet of the SongsTableViewCell class (same as the label). And set the target/action from the Interface Builder (add #IBAction in front of "func cellSongClicked" and ctrl-drag from IB)
2.add the following property to your class:private var currentSong : Int?
3) method cellForRowAtIndexPath:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("SongTitleCell", forIndexPath: indexPath) as SongsTableViewCell
let songDic : NSDictionary = arrSongs.objectAtIndex(indexPath.row) as NSDictionary
cell.lblSongTitle.text = songDic.objectForKey("SongTitle") as? String
cell.btnPlayPause.tag = indexPath.row
var title : String
if let _currentSong = currentSong {
title = indexPath.row == _currentSong ? "Stop" : "Play"
} else {
title = "Play"
}
cell.btnPlayPause.setTitle(title, forState: UIControlState.Normal)
return cell
}
4) And the action:
#IBAction func cellSongClicked (sender : AnyObject ){
var remote = GetSongData()
remote.delegate = self
var btnCurrentPressed = sender as UIButton
//Play Selected Song
let songDic : NSDictionary = arrSongs.objectAtIndex(btnCurrentPressed.tag) as NSDictionary
var rowsToReload = [NSIndexPath]()
var stopCurrent = false
if let _currentSong = currentSong {
if btnCurrentPressed.tag == _currentSong {
stopCurrent = true
} else {
rowsToReload.append(NSIndexPath(forRow: _currentSong, inSection:0))
}
}
rowsToReload.append(NSIndexPath(forRow: btnCurrentPressed.tag, inSection:0))
currentSong = stopCurrent ? nil : btnCurrentPressed.tag
self.tableView.reloadRowsAtIndexPaths(rowsToReload, withRowAnimation: .None)
}
You don't have to change the title of the button every time. You could use something like this:
func viewDidLoad {
playButton.setTitle("Play", forState: UIControlState.Normal)
playButton.setTitle("Stop", forState: UIControlState.Selected)
}
Then in your callback method you just change the state of the button and the text will get updated too:
func playAction(sender: UIButton!) {
// Selected means the content is playing
if !sender.selected {
let track = dataOfTracks[sender.tag] as trackDoc
let url = NSURL(string: track.data.url)
player = AVPlayer(URL: url!)
player.play()
} else {
player.pause()
}
// update the state of the button
sender.selected = !sender.selected
}
I consider this to be a more clean solution since you are not comparing strings anymore to make your decision and you are actually using the binary state of the button to keep track of the current state of your content(which is also binary, either playing or not).
If you have more questions, I would be more than happy to help you further, just let me know.
How do I make it so that when I press one button in XCode, the rest of the buttons (including the one that was pressed) become disabled? Of course I still want the function to be carried out by the button that gets pressed. I just don't want the users to be able to press any button more than once, nor do I want them to be able to press another button after they've already pressed a first one. Below are my IBActions for my two buttons in this case:
#IBAction func addVote1(sender: AnyObject) {
var query = PFQuery(className: "VoteCount")
query.getObjectInBackgroundWithId("BiEM17uUYT") {
(voteCount1: PFObject!, error: NSError!) ->Void in
if error != nil {
NSLog("%#", error)
} else {
voteCount1.incrementKey("votes")
voteCount1.saveInBackgroundWithTarget(nil, selector: nil)
}
let votes = voteCount1["votes"] as Int
let votes2 = voteCount1["votes2"] as Int
self.pollResults1.text = "\(votes) votes \(votes2) votes"
}
}
#IBAction func addVote2(sender: AnyObject) {
var query = PFQuery(className: "VoteCount")
query.getObjectInBackgroundWithId("BiEM17uUYT") {
(voteCount1: PFObject!, error: NSError!) -> Void in
if error != nil {
NSLog("%#", error)
} else {
voteCount1.incrementKey("votes2")
voteCount1.saveInBackgroundWithTarget(nil, selector: nil)
}
let votes = voteCount1["votes"] as Int
let votes2 = voteCount1["votes2"] as Int
self.pollResults2.text = "\(votes) votes \(votes2) votes"
}
}
}
Set up #IBOutlet properties for the buttons if you haven't already, then add a lazy var array of the buttons. In the button handler, set each button's enabled property to false.
class ViewController {
#IBOutlet var button1: UIButton!
#IBOutlet var button2: UIButton!
lazy var buttons: [UIButton] = [self.button1, self.button2]
// ...
#IBAction func addVote1(sender: AnyObject) {
for button in self.buttons {
button.enabled = false
}
// ...
}
}
You can loop through all subview in UIView and find if is a UIButton, if is you can disable the button.
func disableButtons() {
for views in view.subviews {
if let button = views as? UIButton {
button.enabled = false
}
}
}
Do one thing, give unique Tag to all buttons. After that create the method which creates button and disable them by using button tags
func disableButton()
{
for tagvalue in 101...102
{
var btnTemp = self.view.viewWithTag(tagvalue) as UIButton;
btnTemp.enabled = false;
}
}
Add above method in your button, as shown in below code
#IBAction func addVote1(sender: AnyObject)
{
//Your code
disableButton()
}
#IBAction func addVote2(sender: AnyObject)
{
//Your code
disableButton()
}
The easiest way is to add a UIView with a background color of UIColor.clearColor() on top. It's invisible and captures all taps.
class ViewController {
private var uiBlocker = UIView()
override func viewDidLoad() {
uiBlocker.backgroundColor = UIColor.clearColor()
}
#IBAction func buttonAction() {
view.addSubView(uiBlocker)
[stuff you want to do]
uiBlocker.removeFromSuperView()
}
}
let subviews : NSArray = headerView.subviews as NSArray
for button in subviews {
if let button = button as? UIButton {
//let btn = button as! UIButton
button.isSelected = false
}
}
sender.isSelected = true
