If someone has experience with WKWebView, please share how to make the background of the view transparent. The WebView object has such option via var drawsBackground: Bool { get set } but it is missing for the WKWebView class. I searched the net and .. found nothing. Before time it was possible to do so via opaque property, but not anymore. There is a getter isOpaque ... and that's it. I don't want to do it via CSS and already tried everything else, like:
webview.wantsLayer = true
webview.layer?.backgroundColor = NSColor.clear.cgColor
If someone can help ...
I. Nikolov
This should work for both macOS 10.11 and macOS 10.12:
if NSAppKitVersion.current.rawValue > 1500 {
webView.setValue(false, forKey: "drawsBackground")
}
else {
webView.setValue(true, forKey: "drawsTransparentBackground")
}
Remark: this has been passed by App Store review.
Your web page should have transparent background as well.

I have made printing functionality for custom NSView of NSPopover by the assigning the following action to button for this NSView in mainController:
#IBOutlet var plasmidMapIBOutlet: PlasmidMapView!
#IBAction func actionPrintfMap(sender: AnyObject)
{
plasmidMapIBOutlet.print(sender)
}
It is working, but the print window has no option for Paper Size and Orientation, see screenshot below.
What should I do to get these options in the print window?
And, how to make the NSView fitting to the printable area? Now it is not fitting.
I have figured out some moments, but not completely. So, I can setup the printing by the following code
#IBAction func actionPrintMap(sender: AnyObject)
{
let printInfo = NSPrintInfo.sharedPrintInfo()
let operation: NSPrintOperation = NSPrintOperation(view: plasmidMapIBOutlet, printInfo: printInfo)
operation.printPanel.options = NSPrintPanelOptions.ShowsPaperSize
operation.printPanel.options = NSPrintPanelOptions.ShowsOrientation
operation.runOperation()
//plasmidMapIBOutlet.print(sender)
}
But, I still have problem. From the code above I can get only orientation (the last, ShowsOrientation), but not both PaperSize and Orientation. How can I manage both ShowsPaperSize and ShowsOrientation?
Finally I have found the answer which is simple to write but it is not really obvious from apple documentation.
operation.printPanel.options.insert(NSPrintPanelOptions.showsPaperSize)
operation.printPanel.options.insert(NSPrintPanelOptions.showsOrientation)
The problem in the code originally posted is that options is being assigned twice, so the first value assigned, ShowsPaperSize is overwritten by the value ShowsOrientation. That's why you only see the ShowsOrientation option in the dialog.
By using multiple insert operations, you are adding options rather than overwriting each time. You can also do it this way which I think reads better:
operation.printPanel.options.insert([.showsPaperSize, .showsOrientation])
And finally, it also works to "set" the options, and by supplying the existing options as the first array value, you achieve the affect of appending:
operation.printPanel.options = [
operation.printPanel.options,
.showsPaperSize,
.showsOrientation
]
(The first array element operation.printPanel.options means that the old options are supplied in the list of new options.)
I am having some issues to get MBProgressHUDModeDeterminateHorizontalBar style to work
Haven't found much around on Swift.
I've tried so far to create an object passing the MBProgressHUDModeDeterminateHorizontalBar as type or attribute it as a mode to an existing HUB object or add an int to the mode... but nothing seems to work.
let spinningActivity = MBProgressHUD.showHUDAddedTo(self.view, animated: true)
spinningActivity.labelText = "Loading"
spinningActivity.detailsLabelText = "Please got get some coffee"
You need to change MBProgressHUD mode. See code bellow.
spinningActivity.mode = .DeterminateHorizontalBar
And update your loading progress:
spinningActivity.progress = /*Your loading progress*/
Hope that help!
I am trying to implement Speech-to-text feature for watchkit app.
I referred this question which has sample code.
Following is the code I tried:
self.presentTextInputControllerWithSuggestions(["Start it", "Stop it"], allowedInputMode: .Plain, completion: { (selectedAnswers) -> Void in
if selectedAnswers.count > 0 {
if let spokenReply = selectedAnswers[0] as? String {
self.label.setText("\(spokenReply)")
}
}
})
label is a label to display text I speak.
When I run it, it shows the screen where you are supposed to speak (Siri kind of screen) and you have two options on top: ‘Cancel', and ‘Done'. Once I am done speaking, I tap on ‘Done’ but screen doesn’t go away or shows me initial screen, I always have to tap on ‘Cancel’ to go back, and I don’t get any speech data in form of text. I checked it and seems like selectedAnswers is always an empty array, unless I tap on the "Start it"/"Stop it" options.
Can anyone help me with this? I want to show the spoken message on label. I have code inside awakeWithContext method in InterfaceController.swift file, am I supposed to put it somewhere else?
I am using iPhone with iOS 9 beta 2 and watchOS 2 beta on AppleWatch.
Thanks!
You can ask for user input and give him suggestion (see Swift example bellow).
self.presentTextInputControllerWithSuggestions(["suggestion 1", "suggestion 2"] allowedInputMode: .Plain, completion: { (answers) -> Void in
if answers && answers.count > 0 {
if let answer = answers[0] as? String {
println("\answer")
}
}
})
If suggestion is nil it goes directly to dictation. It is not working on the simulator but it is on real watch.
Your approach is correct but something is wrong with your SIRI , try changing the language.
It should work like these.
I'm using swift with ios 8.3. I want to open settings app from my application. I know that using the code
UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
will open my app settings. But I don't want to open my app settings. I just want to open the settings app and stay in the main page. If possible, navigate to "Cellular". Is there any way to acheive this?
Try this.
if let appSettings = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(appSettings, options: [:], completionHandler: nil)
}
Xcode 11.5 - iOS > 10
Update on 11-Oct-2016:
It won't work in iOS10 anymore. So far I haven't found any workaround. If you guys have any solution please let me know. thanks.
======================================
if the iOS version <= iOS9, you need set URL types:
You can do in this way:
let url:NSURL! = NSURL(string : "prefs:root=")
UIApplication.sharedApplication().openURL(url)
I have a demo on github: http://github.com/zhihuitang/SettingDemo.git
And you can find all available URLs as follows:
http://iphonedevwiki.net/index.php/Preferences.app
Preferences app registers a private URL scheme, prefs:, the list below details opening specific views 1[2]
prefs:root=General&path=About
prefs:root=General&path=ACCESSIBILITY
prefs:root=AIRPLANE_MODE
prefs:root=General&path=AUTOLOCK
prefs:root=General&path=USAGE/CELLULAR_USAGE
prefs:root=General&path=Bluetooth
prefs:root=General&path=DATE_AND_TIME
prefs:root=FACETIME
prefs:root=General
prefs:root=General&path=Keyboard
prefs:root=CASTLE
prefs:root=CASTLE&path=STORAGE_AND_BACKUP
prefs:root=General&path=INTERNATIONAL
prefs:root=LOCATION_SERVICES
prefs:root=ACCOUNT_SETTINGS
prefs:root=MUSIC
prefs:root=MUSIC&path=EQ
prefs:root=MUSIC&path=VolumeLimit
prefs:root=General&path=Network
prefs:root=NIKE_PLUS_IPOD
prefs:root=NOTES
prefs:root=NOTIFICATIONS_ID
prefs:root=Phone
prefs:root=Photos
prefs:root=General&path=ManagedConfigurationList
prefs:root=General&path=Reset
prefs:root=Sounds&path=Ringtone
prefs:root=Safari
prefs:root=General&path=Assistant
prefs:root=Sounds
prefs:root=General&path=SOFTWARE_UPDATE_LINK
prefs:root=STORE
prefs:root=TWITTER
prefs:root=General&path=USAGE
prefs:root=VIDEO
prefs:root=General&path=Network/VPN
prefs:root=Wallpaper
prefs:root=WIFI
prefs:root=INTERNET_TETHERING
hope this helpful to you.
YES, They made changes in iOS 10, Please change "prefs:" to "App-Prefs:"
guard let profileUrl = URL(string:"App-Prefs:root=General&path=ManagedConfigurationList") else {
return
}
if UIApplication.shared.canOpenURL(profileUrl) {
UIApplication.shared.open(profileUrl, completionHandler: { (success) in
print(" Profile Settings opened: \(success)")
})
}
This bug was referred to here: in ionic changing route causes "TypeError: Cannot read property 'scrollTo' of null"
The answer says that this bug was fixed in beta-13, but I'm using 1.0.0-rc.1 and the bug still appears.
In my case, it the error is showing when navigating back to a page that uses $ionicScrollDelegate.scrollTop()
Is anyone else getting this error after updating to rc.1?
EDIT:
I find that if I do not call $ionicScrollDelegate.scrollTop() automatically when my view loads, the error does not come up. Should I be calling scrollTop() within a specific Ionic event that waits for the right time?
Had the same problem, even with v1.0.0 "uranium-unicorn".
Wrapping the scroll call into a $timeout helped - this is what it looks like in my code:
$timeout(function() {
$ionicScrollDelegate.scrollTo(scrollPosition.left, scrollPosition.top);
}, 0);
You can just put it in
$ionicPlatform.ready(function () {
$ionicScrollDelegate.scrollTop();
})
Im late to this but was getting the same error but by calling the scroll top element with:
$ionicScrollDelegate.scrollTop();
but rather:
var scrollTop = e.detail.scrollTop;
and fixed my by using the following:
var scrollTop = $ionicScrollDelegate.getScrollPosition().top;
Im also using js scrolling as it seems to work better with the scrolla-sista plugin so I have the following in my config block at the start of my app
$ionicConfigProvider.scrolling.jsScrolling(true);
where their docs state:
Whether to use JS or Native scrolling. Defaults to native scrolling. Setting this to true has the same effect as setting each ion-content to have overflow-scroll='false'.
I hope this helps someone
For what it's worth, I saw this solution on this thread here and it worked for me with version 1.0.0-beta.14
If upgrading to version 1.0.0-beta.14 is not an option, you can change the ionic-bundle.js file with the following:
Approximately Line 39910:
this.scrollTop = function(shouldAnimate) {
this.resize().then(function() {
if(typeof scrollView !== 'undefined' && scrollView !== null){
scrollView.scrollTo(0, 0, !!shouldAnimate);
}
});
};
And Approximately line 39813:
if (!angular.isDefined(scrollViewOptions.bouncing)) {
ionic.Platform.ready(function() {
if(!scrollView){
return;
}
scrollView.options.bouncing = true;
if(ionic.Platform.isAndroid()) {
// No bouncing by default on Android
scrollView.options.bouncing = false;
// Faster scroll decel
scrollView.options.deceleration = 0.95;
}
});
}
Please change
e.detail.scrollTop
to
e.target.scrollTop
then this will Work
