open var buttonInit: ((_ index: Int) -> UIButton?)?
...
if let button: UIButton = self.buttonInit?(i) {
finButton = button
}else {
let button = UIButton(type: .custom)
button.setTitleColor(button.tintColor, for: [])
button.layer.borderColor = button.tintColor.cgColor
button.layer.borderWidth = 1
button.layer.cornerRadius = buttonHeight/2
finButton = button
}
I don't find any function description about buttonInit in AZDialogViewController. Does it mean button: UIButton = self.buttonInit?(i) will always be nil and finButton = button will not be executed?
The latter part of the code you quoted is in the setUpButton method:
fileprivate func setupButton(index i:Int) -> UIButton{
if buttonHeight == 0 {buttonHeight = CGFloat(Int(deviceHeight * 0.07))}
let finButton: UIButton
if let button: UIButton = self.buttonInit?(i) {
finButton = button
}else {
let button = UIButton(type: .custom)
button.setTitleColor(button.tintColor, for: [])
button.layer.borderColor = button.tintColor.cgColor
button.layer.borderWidth = 1
button.layer.cornerRadius = buttonHeight/2
finButton = button
}
This method is called here:
open func addAction(_ action: AZDialogAction){
actions.append(action)
if buttonsStackView != nil{
let button = setupButton(index: actions.count-1)
self.buttonsStackView.addArrangedSubview(button)
//button.frame = buttonsStackView.bounds
button.center = CGPoint(x: buttonsStackView.bounds.midX,y: buttonsStackView.bounds.maxY)
animateStackView()
}
}
From this we can see that buttonInit seems to be used to let the user of the library specify what kind of button they want as the action buttons. Another piece of evidence is that buttonInit is declared open, so it is likely that it is the client code who should set this, not the AZDialogViewController.
Plus, the README file showed this usage:
Use custom UIButton sub-class:
dialog.buttonInit = { index in
//set a custom button only for the first index
return index == 0 ? HighlightableButton() : nil
}
So to answer your question, the if branch will be executed if you set buttonInit.
#Huwell,
the documentation in the repository states to initialize the button in the following manner:
dialog.buttonInit = { index in
//set a custom button only for the first index
return index == 0 ? HighlightableButton() : nil
}
The button should be part of your DialogViewController.
I have in my app in my View a Button for taking snapshot with below code
open func takeScreenshot(_ shouldSave: Bool = true) -> UIImage? {
var screenshotImage :UIImage?
let layer = UIApplication.shared.keyWindow!.layer
let scale = UIScreen.main.scale
UIGraphicsBeginImageContextWithOptions(layer.frame.size, false, scale);
guard let context = UIGraphicsGetCurrentContext() else {return nil}
layer.render(in:context)
screenshotImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
if let image = screenshotImage, shouldSave {
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
}
return screenshotImage
}
But in the same View is UIImageView and I want to take a snapshot of this UIImageView. How should I change the code? When I take a snapshot with this code, it will save only black screen with button for play/pause video and with button for taking snapshot.
Instead you using
let layer = UIApplication.shared.keyWindow!.layer
Just use your imageview Layer
let layer = YourImageView.layer
I have a osx (MacOS) application with a mainwindowController and the user can maximise the view. The app also has a preferences window that opens as a childwindowcontroller.
However if the main window is maximised the child window also tries to be maximised which ends up with a black screen with the child window display in the middle.
Is there anyway to make the child window not be displayed based on the main window maximised state and the child window always not be maximised.
Here is some code of how the preferences window is displayed.
let currentWindowController = self.view.window?.windowController as! MainWindowViewController
let childWindowControllers = windowControllers[currentWindowController]
if let subPreferencesWindowController: SubPreferenceWindowViewController? = {
for windowController in childWindowControllers! {
if windowController is SubPreferenceWindowViewController {
return windowController as? SubPreferenceWindowViewController
}
}
return nil
}(){
let subPreferencesController = subPreferencesWindowController?.contentViewController as! SubPreferenceViewController
subPreferencesController.appStateJSON = self.appStateJSON!
subPreferencesController.preferences = self.preferencesJSON!
subPreferencesController.setUpSubPreferences()
}
SOLVED IT - When I create the window I add a styling mask to set the new window to not be resizable. (Last line of code)
if let subPreferenceViewController = storyboard.instantiateController(withIdentifier: NSStoryboard.SceneIdentifier(rawValue: "sub-preferences")) as? SubPreferenceViewController {
let subPreferenceWindow = NSWindow(contentViewController: subPreferenceViewController)
let subPreferenceWindowController = SubPreferenceWindowViewController(window: subPreferenceWindow)
var windowControllersForCurrent = windowControllers[currentWindowController]
windowControllersForCurrent?.append(subPreferenceWindowController)
windowControllers[currentWindowController] = windowControllersForCurrent
newWindowController = subPreferenceWindowController
newWindow = subPreferenceWindow
newWindow.standardWindowButton(.zoomButton)!.isHidden = true
width = 400
height = 607
newWindow.maxSize = NSSize(width: width, height: height)
newWindow.styleMask.remove(.resizable)
}
I'm sorry but if I have a number of buttons that comes from a plist file ...
how do I re-create all the buttons?
Example I tried in this way :
func loadSavedButtons() {
// I extract the number from the plist file
var number: AnyObject? = data.valueForKey("NumberOfButton")
var someNumb: Int = ("\(number!)").toInt()!
if (someNumb != 0) {
self.countButton = someNumb
for (var i=0; i < someNumb; i++) {
In This Point I should do
var newButton6: () = CreateButtonWithIndex(i)
self.view.addSubview(newButton6)
}}}
and
#IBAction func CreateButtonWithIndex(sender: AnyObject){
let button = UIButton.buttonWithType(UIButtonType.System) as UIButton
ecc…
self.view.addSubview(button)
but don't go ... i don't have all save button please help me !!!
In your function
Change the following
let button = UIButton.buttonWithType(UIButtonType.System) as UIButton
to
var button = UIButton.buttonWithType(UIButtonType.System) as UIButton
then after
self.view.addSubview(button)
add the following:
button = UIButton.new()
I'm a newbie in appcelerator.titanium. I started development from today onwards.
My problem is,
I want to display a page curl transition effect when a button is tapped on one of my view.
I used the following code for doing this. But the application is crashed. I searched a lot in SO and titanium documentation. But couldn't find a solution.
//This function returns a window
function ApplicationWindow()
{
//load component dependencies
var FirstView = require('ui/common/FirstView');
//create component instance
var self = Ti.UI.createWindow({
backgroundColor:'#ffffff'
});
//construct UI
var firstView = new FirstView();
self.add(firstView);
//Adding button for displaying view 2
var button1 = Ti.UI.createButton({
height : '50',
width : '50%',
top : '70%',
title : 'Add Child'
});
//Adding event listner for button
button1.addEventListener('click',function(e){
var view = createView();
win.add(view);
});
self.add(button1);
//creating second view
function createView()
{
var view = Ti.UI.createView({
backgroundColor : '#aabbcc'
});
//creating button for view 2
var button2 = Ti.UI.createButton({
height : '50',
width : '50%',
top : '70%',
title : 'Show Curl'
});
//Adding event listner for button
button2.addEventListener('click',function(e)
{
//creating animation
var animation = Titanium.UI.createAnimation({
transition : Ti.UI.iPhone.AnimationStyle.CURL_UP
});
animation.backgroundColor = 'black';
animation.duration = 1000;
var animationHandler = function() {
animation.removeEventListener('complete',animationHandler);
animation.backgroundColor = 'orange';
view.animate(animation);
};
animation.delay = 5000
animation.addEventListener('complete',animationHandler);
view.animate(animation);
});
view.add(button2);
return view;
}
return self;
}
//creating window and opening
var win = ApplicationWindow();
win.open();
Thanks in advance
