While button is pressed I'd like to show upon the existing JSQMessagesInputToolbar new view with timer and slider for cancellation.
One of the solution I found is overriding xib files but
all UI in the project is written in Objective C, so there is no xib files I could override.
Could you please advice alternative programmatic solution to implement it?
Thank you
//MARK:- Input Toolbar Initialization
private func initRightToolBarView() -> Void {
micButton = UIButton(frame: inputButtonFrame)
micButton.setImage(CHAT_MIC_BUTTON,for:UIControlState())
micButton.addTarget(self, action: #selector(startRecording), for: .touchDown)
micButton.addTarget(self, action: #selector(endRecording), for: .touchUpInside)
micButton.addTarget(self, action: #selector(cancelRecording), for: .touchDragExit)
inputToolbar.contentView!.rightBarButtonContainerView!.addSubview(micButton)
let timerLabelFrame = inputToolbar.contentView!.textView!.frame
timerLabel = UILabel(frame: timerLabelFrame)
timerLabel.text = "00:00"
timerLabel.textAlignment = .center
timerLabel.isHidden=true
inputToolbar.contentView!.addSubview(timerLabel)
}
Now when the user starts recording then
inputToolbar.contentView!.textView!.isHidden = true
timerLabel.isHidden=false
when recording ends
inputToolbar.contentView!.textView!.isHidden = false
timerLabel.isHidden=true

I have a grid of UIButtons and I'd like to call a haptic effect for the following methods:
When the user moves their finger over a button for the first time
When the user lifts their finger (a typical tap, .touchUpInside works perfectly)
Any suggestions for how to call a haptic effect when the user moves over a button for the first time?
button.addTarget(self, action: #selector(tap), for: .touchUpInside)
button.addTarget(self, action: #selector(moveOver), for: .??)
func moveOver(sender:UIButton) -> Bool {
let generator = UIImpactFeedbackGenerator(style: .heavy)
generator.impactOccurred()
return true
}
The correct UIEventAction to use in this case is touchDragInside
I'm currently working on a project in Xamarin.iOS and I don't have any idea how the stack system works.
I have a menu where I choose the language of my app and I would like to refresh on the fly the language on all the previous pages when I select a different language.
When I tap on the previous button in my language settings the previous page is not translated so I decided to create a new ViewController that I put on the top of the stack with this.NavigationController.PushViewController(new ViewController(), true)
but I don't think it's the best way to do it so I tried
this.NavigationController.PopToRootViewController(true) to have the root ViewController but is there a way to get just the previous page on the stack?
public override void RowSelected(UITableView tableView, NSIndexPath indexPath)
{
var cell = this.GetCell(tableView, indexPath);
cell.SelectionStyle = UITableViewCellSelectionStyle.None;
var previousIndexPath = NSIndexPath.FromRowSection(this.selectedIndex, 0);
this.selectedIndex = indexPath.Row;
var selectedLanguage = this.supportedCultures[this.selectedIndex];
Localization.Culture = selectedLanguage;
this.SaveLanguageToUserDefault(selectedLanguage);
this.TableView.ReloadRows(new NSIndexPath[] { previousIndexPath,indexPath }, UITableViewRowAnimation.None);
this.NavigationController.PopToRootViewController(true);
//this.NavigationController.PushViewController(new ViewController(), true);
}
In iOS if you are using a NavigationController and you want to Navigate to the previous ViewController you use the PopViewController Method in the NavigationProperty.
this.NavigationController.PopViewController(true);
This will make you app close the current page you are and will show the previous one.
Look that this is different to the PopToRootViewController.
Hope this helps.-
When you press back button ViewDidAppear medthod getting called in the coming page. Here you write your logic like after opening notification when going back setting count 0 etc
public override void ViewDidAppear(bool animated)
{
base.ViewDidAppear(animated);
DashboardItem.NotificationCount = 0;
}
Image download from right click "Context Menu" not responding in the web page loaded in WKWebview. If any body knows help me to identify which delegate method will receive this call or is there any manual implementation needed to get this option work.
App:Mac Application. Language : Objective C. SDK: Xcode
You can intercept context menu items of the WKWebView class by subclassing it and implementing the willOpenMenu method like this:
class MyWebView: WKWebView {
override func willOpenMenu(_ menu: NSMenu, with event: NSEvent) {
for menuItem in menu.items {
if menuItem.identifier?.rawValue == "WKMenuItemIdentifierDownloadImage" ||
menuItem.identifier?.rawValue == "WKMenuItemIdentifierDownloadLinkedFile" {
menuItem.isHidden = true
}
}
}
}
I'm using the today widget for iOS8 to display information relevant to the current day. The problem is I don't want to display the widget/section at all if there are no relevant messages to show.
I know it must be possible as the BA app does it (it only shows the widget when there is a flight, the rest of the time its not visible at all). I just cant figure out a way to achieve this behaviour.
Does anyone know how this can be done?
I found the way to do this is using the NCWidgetController. This allows you to easily specify when the today widget should be displayed based on whatever criteria you see fit.
Simply add the following into your viewDidLoad method (or anywhere that will be called when the widget reloads) in the today widget view controller and it will work:
BOOL hasDataToDisplay = NO;
NCWidgetController *widgetController = [NCWidgetController widgetController];
[widgetController setHasContent:hasDataToDisplay forWidgetWithBundleIdentifier:#"com.my-company.my-app.my-widget"];
Apple Docs: https://developer.apple.com/library/ios/documentation/NotificationCenter/Reference/NCWidgetController_Class/index.html#//apple_ref/occ/cl/NCWidgetController
WARNING: The NCWidgetController cannot be reset from the widget itself once you have set there is no content to display. In other words once you set it to NO then there is no going back unless you trigger it from the parent/containing app.
In the widget's ViewController's viewDidLoad method add the following:
BOOL DisplayWidget = NO;
[[NCWidgetController widgetController] setHasContent:DisplayWidget
forWidgetWithBundleIdentifier:#"<widget's bunder identifier>"];
This will disable the widget from showing.
To enable it again, you must do that from the containing app using the same line passing YES to setHasContent parameter. Make sure to add the necessary imports to the containing app in the ViewController which will re-enable the widget:
#import <NotificationCenter/NotificationCenter.h>
#interface ViewController () <NCWidgetProviding> {...}
[Check out page 41 of the documentations for widgets
https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/ExtensibilityPG.pdf ]
The approach which I used, though not perfect and has a small remnant in Notification Center, but worked for me:
In viewDidLoad() set preferred content size height to 1:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view from its nib.
preferredContentSize = CGSizeMake(0, 1)
view.setNeedsLayout()
}
then when widget updates, gets real height and set it:
var data: NSData?
func updateData() {
// fetch data
if let data = data {
let viewHeight: CGFloat
// UI preperation and initialize viewHeight var
preferredContentSize = CGSizeMake(0, viewHeight);
} else {
preferredContentSize = CGSizeMake(0, 1);
}
}
func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)) {
// Perform any setup necessary in order to update the view.
// If an error is encountered, use NCUpdateResult.Failed
// If there's no update required, use NCUpdateResult.NoData
// If there's an update, use NCUpdateResult.NewData
updateData()
completionHandler(data != nil ? NCUpdateResult.NewData : NCUpdateResult.NoData)
}
It is better use
+ (instancetype)widgetController
then call
- (void)setHasContent:(BOOL)flag forWidgetWithBundleIdentifier:(NSString *)bundleID
We have a parent Split view (NSSplitView), and two subviews, Content and SideBar (the sidebar is on the right).
What would be the optimal Cocoa-friendly way to toggle the SideBar view?
I would really love it, if the suggested solution includes animation
I really don't need any suggestions related to external plugins, etc (e.g. BWToolkit)
HINT : I've been trying to do that, but still I had issues hiding the divider of the NSSplitView as well. How could I do it, while hiding it at the same time?
Here's a pretty decent tutorial that shows how to do this: Unraveling the Mysteries of NSSplitView.
Hiding the divider is done in NSSplitView's delegate method splitView:shouldHideDividerAtIndex:.
You will have to animate the frame size change yourself if you don't like the way NSSplitView does it.
Easiest way to do it is as follows - and it's animated: [SWIFT 5]
splitViewItems[1].animator().isCollapsed = true // Show side pane
splitViewItems[1].animator().isCollapsed = false // hide side pane
I wrote a Swift version of the content in the link from #Nathan's answer that works for me. In the context of my example splitView is set elsewhere, probably as an instance property on an encompassing class:
func toggleSidebar () {
if splitView.isSubviewCollapsed(splitView.subviews[1] as NSView) {
openSidebar()
} else {
closeSidebar()
}
}
func closeSidebar () {
let mainView = splitView.subviews[0] as NSView
let sidepanel = splitView.subviews[1] as NSView
sidepanel.hidden = true
let viewFrame = splitView.frame
mainView.frame.size = NSMakeSize(viewFrame.size.width, viewFrame.size.height)
splitView.display()
}
func openSidebar () {
let sidepanel = splitView.subviews[1] as NSView
sidepanel.hidden = false
let viewFrame = splitView.frame
sidepanel.frame.size = NSMakeSize(viewFrame.size.width, 200)
splitView.display()
}
These functions will probably methods in a class, they are for me. If your splitView can be nil you obviously have to check for that. This also assumes you have two subviews and the one at index 1, here as sidePanel is the one you want to collapse.
In Xcode 9.0 with Storyboards open Application Scene select View->Menu->Show sidebar. CTRL-click Show Sidebar, in sent actions delete the provided one, click on x. From the circle CTRL drag to First Responder in application scene and select toggleSideBar to connect to. Open storyboard and select the first split view item and in attributes inspector change behaviour from default to sidebar. Run and try with view menu item show/hide. All done in interface builder no code. toggleSideBar handles the first split view item. https://github.com/Dis3buted/SplitViewController
I got some artifacts with the code above, likely because it was out of context. I am sure it works where it was meant to. Anyway, here is a very streamlined implementation:
// this is the declaration of a left vertical subview of
// 'splitViewController', which is the name of the split view's outlet
var leftView: NSView {
return self.splitViewController.subviews[0] as NSView
}
// here is the action of a button that toggles the left vertical subview
// the left subview is always restored to 100 pixels here
#IBAction func someButton(sender: AnyObject) {
if splitViewController.isSubviewCollapsed(leftView) {
splitViewController.setPosition(100, ofDividerAtIndex: 0)
leftView.hidden = false
} else {
splitViewController.setPosition(0, ofDividerAtIndex: 0)
leftView.hidden = true
}
}
To see a good example using animations, control-click to download this file.
If your NSSplitView control is part of a NSSplitViewController object, then you can simply use this:
splitViewController.toggleSidebar(nil)
