I am developing a MacOS app for to edit metadata of image. For this purpose, I use CGImageDestinationCreateWithURL function for to create destination to the file located in 'Documents' or 'Desktop' but it returns nil value. I checked paremeters of the function (URL and file type) several times but can not find reason of the issue.
Here is the code
#IBAction func browseFile(_ sender: AnyObject) {
let dialog = NSOpenPanel()
dialog.title = "Choose a .txt file"
dialog.showsResizeIndicator = true
dialog.showsHiddenFiles = false
dialog.canChooseDirectories = true
dialog.canCreateDirectories = true
dialog.allowsMultipleSelection = false
dialog.allowedFileTypes = nil
if dialog.runModal() == NSApplication.ModalResponse.OK {
let result = dialog.url // Pathname of the file
if result != nil {
let path = result!.path
filename_field.stringValue = path
let imageSource = CGImageSourceCreateWithURL(result as! CFURL, nil)
let type = CGImageSourceGetType(imageSource!)
let uurl = NSURL(fileURLWithPath: path)
// here I am trying to create a destination but it returns nil
var imageDest: CGImageDestination = CGImageDestinationCreateWithURL(uurl, type!, 1, nil)!
}
} else {
// User clicked on "Cancel"
return
}
}

If a try to set the allowedContentTypes for an NSOpenPanel, I get always the message that this isn't a member. I cannot use the openPanel.allowedFileTypes because it is deprecated.
I didn't change any setting for the project. It was defined primary as an empty object, and then a added a macOS target
In the source I only import Cocoa
See code:
let openPanel = NSOpenPanel()
openPanel.title = "SelectImageTitle"
openPanel.prompt = "SelectImagePrompt"
openPanel.nameFieldLabel = "SelectImageLabel"
openPanel.showsResizeIndicator = true
openPanel.showsHiddenFiles = false
openPanel.allowsMultipleSelection = false
openPanel.canChooseDirectories = false
//openPanel.allowedFileTypes = allowedImageTypes
openPanel.allowedContentTypes = [.png]
// openPanel
//----- Perform the selection dialog ----------------------------------------------------------------------------
guard openPanel.runModal() == .OK else { return nil }
return openPanel.url?.path
I'm using Google AdMob to display native ads on my app. I made everything as in the Google Documentation. After testing, I figured out that test ad values are loading successfully since they aren't nil and when I print them, I can see them as they should display. However data is not displaying on my GADNativeAdView. Here is some of my code:
var nativeAdView: GADNativeAdView! {
didSet {
nativeAdView.translatesAutoresizingMaskIntoConstraints = false
containerView.addSubview(nativeAdView)
nativeAdView.leftAnchor.constraint(equalTo: collectionView4.leftAnchor).isActive = true
nativeAdView.rightAnchor.constraint(equalTo: collectionView4.rightAnchor).isActive = true
nativeAdView.topAnchor.constraint(equalTo: collectionView4.bottomAnchor, constant: 10).isActive = true
nativeAdView.heightAnchor.constraint(equalToConstant: 310).isActive = true
}
}
var adLoader: GADAdLoader!
// MARK: - Google Mobile Ads
extension HomeController: GADNativeAdLoaderDelegate, GADNativeAdDelegate {
private func setupAd() {
let multipleAdsOptions = GADMultipleAdsAdLoaderOptions()
multipleAdsOptions.numberOfAds = 1
adLoader = GADAdLoader(adUnitID: testNativeId, rootViewController: self,
adTypes: [.native],
options: [multipleAdsOptions])
adLoader.delegate = self
adLoader.load(GADRequest())
}
func imageOfStars(from starRating: NSDecimalNumber?) -> UIImage? {
guard let rating = starRating?.doubleValue else {
return nil
}
if rating >= 5 {
return UIImage(named: "stars_5")
} else if rating >= 4.5 {
return UIImage(named: "stars_4_5")
} else if rating >= 4 {
return UIImage(named: "stars_4")
} else if rating >= 3.5 {
return UIImage(named: "stars_3_5")
} else {
return nil
}
}
func adLoader(_ adLoader: GADAdLoader, didReceive nativeAd: GADNativeAd) {
// Create and place ad in view hierarchy.
let nibView = Bundle.main.loadNibNamed("NativeAdView", owner: nil, options: nil)?.first
guard let nativeAdView = nibView as? GADNativeAdView else {
return
}
self.nativeAdView = nativeAdView
nativeAd.delegate = self
(nativeAdView.headlineView as? UILabel)?.text = nativeAd.headline
nativeAdView.mediaView?.mediaContent = nativeAd.mediaContent
(nativeAdView.bodyView as? UILabel)?.text = nativeAd.body
nativeAdView.bodyView?.isHidden = nativeAd.body == nil
(nativeAdView.callToActionView as? UIButton)?.setTitle(nativeAd.callToAction, for: .normal)
nativeAdView.callToActionView?.isHidden = nativeAd.callToAction == nil
(nativeAdView.iconView as? UIImageView)?.image = nativeAd.icon?.image
nativeAdView.iconView?.isHidden = nativeAd.icon == nil
(nativeAdView.starRatingView as? UIImageView)?.image = imageOfStars(from: nativeAd.starRating)
nativeAdView.starRatingView?.isHidden = nativeAd.starRating == nil
(nativeAdView.storeView as? UILabel)?.text = nativeAd.store
nativeAdView.storeView?.isHidden = nativeAd.store == nil
(nativeAdView.priceView as? UILabel)?.text = nativeAd.price
nativeAdView.priceView?.isHidden = nativeAd.price == nil
(nativeAdView.advertiserView as? UILabel)?.text = nativeAd.advertiser
nativeAdView.advertiserView?.isHidden = nativeAd.advertiser == nil
nativeAdView.callToActionView?.isUserInteractionEnabled = false
nativeAdView.nativeAd = nativeAd
}
func adLoader(_ adLoader: GADAdLoader, didFailToReceiveAdWithError error: Error) {
print("ERROR: \(error.localizedDescription)")
}
}
Here is my .xib file:
The views custom class on the .xib file are set.
After trial and error I figured out that using #IBOutlet for views in the .xib file and calling them on the adLoader(_:) worked.
I'm working on status bar app.
I want to show file picker to select my image.
Here is my code:
Button("Select image") {
let openPanel = NSOpenPanel()
openPanel.prompt = "Select File"
openPanel.allowsMultipleSelection = false
openPanel.canChooseDirectories = false
openPanel.canCreateDirectories = false
openPanel.canChooseFiles = true
openPanel.allowedFileTypes = ["png","jpg","jpeg"]
openPanel.begin { (result) -> Void in
if result.rawValue == NSApplication.ModalResponse.OK.rawValue {
let selectedPath = openPanel.url!.path
if let nsData = NSData(contentsOfFile: selectedPath) {
imageData = Data(referencing: nsData)
}
}
}
}
It's shown, but behind my app (which is not on status bar)
So how to just show file picker and hide that weird view.
I have code like below. For some file I got metadata like artist, title and other without any problem. For other files metadata list is nil but when I check metadata in editor like Tagger - title and other metadata exists. Furthermore when I change metadata in external editor for at least one key - my code starts work properly.
Could someone explain me where I make mistake ?
static func getBookInCatalog(url: URL) -> Book {
let book = Book(url: url)
let isDir: ObjCBool = false
var directoryContents = [URL]()
var totalTime: CMTime?

var chapters:Int = 0
do {

}

}
}
}
}
}

book.image = imageInsideCatalog
}
if book.title == nil {
book.title = url.deletingPathExtension().lastPathComponent
}
book.chapters = chapters
book.totalTime = totalTime
book.size = size
return book
}
MP3 meta data "standards" have gone through several major iterations over the years (see http://id3.org) . Your editor may be able to read older formats (that AVURLAsset may not support) and save them using the latest/current standard which would make them compatible after any change.
Ive looked around at other answers, but nothing seems to be helping my case.
I have a viewController class which contains an IBAction for a button. This button should open a NSOpenPanel as a sheet from that viewController:
class ViewController: NSViewController {
#IBAction func folderSelection(sender: AnyObject) {
var myFiledialog: NSOpenPanel = NSOpenPanel()
myFiledialog.prompt = "Select path"
myFiledialog.worksWhenModal = true
myFiledialog.allowsMultipleSelection = false
myFiledialog.canChooseDirectories = true
myFiledialog.canChooseFiles = false
myFiledialog.resolvesAliases = true
//myFiledialog.runModal()
myFiledialog.beginSheetModalForWindow(self.view.window!, completionHandler: nil)
var chosenpath = myFiledialog.URL
if (chosenpath!= nil)
{
var TheFile = chosenpath!.absoluteString!
println(TheFile)
//do something with TheFile
}
else
{
println("nothing chosen")
}
}
}
The problem comes from myFileDialog.beginSheetModalForWindow(..) , it works with the line above, but that is not a sheet effect
You need to call beginSheetModalForWindow from your panel on your window, and use a completion block:
let myFiledialog = NSOpenPanel()
myFiledialog.prompt = "Select path"
myFiledialog.worksWhenModal = true
myFiledialog.allowsMultipleSelection = false
myFiledialog.canChooseDirectories = true
myFiledialog.canChooseFiles = false
myFiledialog.resolvesAliases = true
myFiledialog.beginSheetModalForWindow(window, completionHandler: { num in
if num == NSModalResponseOK {
let path = myFiledialog.URL
print(path)
} else {
print("nothing chosen")
}
})
Swift 5
let dialog = NSOpenPanel()
dialog.beginSheetModal(for: self.view.window!){ result in
if result == .OK, let url = dialog.url {
print("Got", url)
}
}
