I am working on iOS custom keyboard. In this I need to show stickers and gifs in the custom keyboard, I'm able to show the images on the keyboard, but the problem is, when user select an image from the keyboard I want to show it on the textDocumentProxy. After doing some research I understood that it's not possible to insert the images as the textDocumentProxy.insertText. So I tried UIPasteboardto copy the image from the keyboard and paste it into the input field like this.
Here my code :
let pb = UIPasteboard.generalPasteboard()
let image: UIImage = UIImage(named: "1.png")!
let imgData: NSData = UIImagePNGRepresentation(image)!
pb.setData(imgData, forPasteboardType: kUTTypePNG as String)
pb.image = image
And I also set the RequestsOpenAccess to true in .plist file and allowed access for the custom keyboard in the device as well. But it's not working for me.
Please suggest the possible ways to do this. Thanks in advance.
You want to use gif images in custom keyboard link. and in above code you are using png image.
If you want to copy non gif image then you can use below code for Swift 3
#IBOutlet weak var imageview: UIImageView!
var img : UIImage = UIImage(named:"1.png")!
imageview = UIImageView(image: img)
//copy image code
UIPasteboard.general.image = imageview.image!
or If you want to use gif image then you can use below code for Swift 3
let url = Bundle.main.url(forResource: "imagename", withExtension: ".gif")
let data: NSData = NSData(contentsOf: url!)!
UIPasteboard.general.setData(data as Data, forPasteboardType: "com.compuserve.gif")

I did try with Cocapods "Kingfisher" but cannot figure out how to set an animating placeholder image while the image is being downloaded.
here is the Below code I tried with kingfisher Pod
func configureCell(category:Category){
if let url = URL(string: category.imgUrl){
let placeholder = UIImage(named: "placeholder")
let options : KingfisherOptionsInfo = [KingfisherOptionsInfoItem.transition(.fade(0.1))]
categoryImg.kf.indicatorType = .activity
categoryImg.kf.setImage(with: url, placeholder: placeholder, options: options)
}
}
This is actually not an image but a UIView. The best option would be to use SkeletonView.
SkeletonView has been conceived to address this need, an elegant way to show users that something is happening and also prepare them to which contents he is waiting.
This animation is called Shimmer effect . You can use this link for your help

I'm trying to share a story with a background image a a sticker image via URL Scheme on my ios app, i am using the attached code and it dose not work.
When i'm trying to share just a background image or just a sticker it does work. But when im trying share both a background image and a sticker in top of it, it dose not work.
Any Ideas?
func shareToInstagram(deepLinkString : String){
let url = URL(string: "instagram-stories://share")!
if UIApplication.shared.canOpenURL(url){
let backgroundData = UIImageJPEGRepresentation(UIImage(named: "shop_placeholder")!, 1.0)!
let creditCardImage = UIImage(named: "share_instagram")!
let stickerData = UIImagePNGRepresentation(creditCardImage)!
let pasteBoardItems = [
["com.instagram.sharedSticker.backgroundImage" : backgroundData],
["com.instagram.sharedSticker.stickerImage" : stickerData],
]
if #available(iOS 10.0, *) {
UIPasteboard.general.setItems(pasteBoardItems, options: [.expirationDate: Date().addingTimeInterval(60 * 5)])
} else {
UIPasteboard.general.items = pasteBoardItems
}
UIApplication.shared.openURL(url)
}
I copy pasted OP's code for use in my own app (only substituting different UIImages) and found only 1 issue, pasteboard items should be contained in a single array otherwise instagram will render only the first item (in this case the background layer). To fix this, replace the declaration of pasteboard items with the following code
let pasteBoardItems = [
["com.instagram.sharedSticker.backgroundImage" : backgroundData,
"com.instagram.sharedSticker.stickerImage" : stickerData]
]
(basically just remove the close and open bracket separating the two items)
Also as a previous answer stated, make sure "instagram-stories" is included in LSApplicationQueriesSchemes in the info.plist file
I use this exact code in my app and it now works perfect
Everything is correct, my code is similar and it works for iOS 11+. I suggest you the following:
check the image data you pass to pasteboard (jpg can't be converted with
UIImagePNGRepresentation and vice versa)
check the info.plist. You should enable "instagram-stories" scheme in it (LSApplicationQueriesSchemes key)
Like Alec said, you need to put all of Instagram data in one list, not multiple lists. look at the example from the meta documents:
NSArray *pasteboardItems = #[#{#"com.instagram.sharedSticker.stickerImage" : stickerImage,
#"com.instagram.sharedSticker.backgroundTopColor" : backgroundTopColor,
#"com.instagram.sharedSticker.backgroundBottomColor" : backgroundBottomColor}];
2. For more recent readers, as of swift 4.2 and iOS 12 UIImageJPEGRepresentation is replaced by jpegData. change
let backgroundData = UIImageJPEGRepresentation(yourImage, 1.0)
with
let backgroundData = yourImage.jpegData(compressionQuality: 1.0)
Currently creating an basic image slideshow application, To do this i have created an UIImage array and calling them with the following code.
let imageNames = (0...50).map
{
"\($0).JPG"
}
let image = UIImage(named: imageNames[0])
imageView.animationImages = image
imageView.animationDuration = 50
imageView.startAnimating()
Was wondering if anyone would be able to offer some advice.
The issue isn't how much memory the image takes on disk, it's about the memory required to address all the pixels on your screen. You don't really need to store the images before you use them. One image of less than 1MB will load very quickly.
Instead you just need to keep a path to the image, and only when you get to the code that displays the image, then you load it, and display it.
So, combining Alexander's and KKRocks on-point answers:
In the top of your class, define your array of filenames:
let imageNames = (0...55).map { "\($0).JPG" }
Where you are displaying your image:
if let image = UIImage(named: images[0]) {
... the code that is blowing up ...
}
If you are not sure how to save a file and retrieve it, please see this answer I recently gave on that subject:
Saving and Retrieving Files in User's Space.
You need to add image name in array instead of UIImage .
let images: [String] = [
"0.JPG",
"1.JPG")!]
Get image from string of array
let image = UIImage(named: images[0])
I have bunch of tile images inside the folder called "Tiles"
I need to extract one image at a time from that folder, and set it to UIView object.
I am stuck on how to get the image from inside that folder.
Can anyone help do this in Swift?
If you have the image name,you can just access the image in this folder like this
let image = UIImage(named: "image.png")
Or this
let imageURL = NSBundle.mainBundle().URLForResource("image", withExtension: "png")
let image = UIImage(contentsOfFile: imageURL!.path!)
If you want get all images,you create a real folder inside the project
let imageArray = NSBundle.mainBundle().URLsForResourcesWithExtension("png", subdirectory: "Titles") as! [NSURL]
This will return an urlArray of png inside Titles folder.You can use contentsOfFile as show before to access image
I recently saw this project in which a user can tap on a GIF from a custom keyboard and they would see a "copied" toolip appear. I have one question:
How does one reproduce this tooltip in the products GIF-Tutorial?
Could anyone give me some sample code to work with. I understand how to use UIPasteboard and it's functions, but I can't seem to get it to work when I put in the UTI type "public.png" in this function: (I noticed in Objective-c it's "#public.png", but I placed "public.png" I couldn't find a source online for this)
let imageURL = NSString(string:NSBundle.mainBundle().pathForResource("test", ofType: "png")!)
var data = NSData(contentsOfURL: NSURL(string:imageURL)!)
UIPasteboard.generalPasteboard().setData(data!, forPasteboardType: "public.png")
Try using this code:
let image = UIImage(named: "myimage.png")
UIPasteboard.generalPasteboard().image = image;
you can find out how this works here!
Hope this helps
Swift 5.1
UIPasteboard.general.image = image
When using UIPasteboard.generalPasteboard().image = image; it seems the image is not copied to the pasteboard. Instead try the next code, it also explains how you can replace "public.png" string:
// The Pasteboard is nil if full access is not granted
// 'image' is the UIImage you about to copy to the pasteboard
if let pb = UIPasteboard.generalPasteboard() {
let type = UIPasteboardTypeListImage[0] as! String
if !type.isEmpty {
pb.setData(UIImagePNGRepresentation(image), forPasteboardType: type)
if let readData = pb.dataForPasteboardType(type) {
let readImage = UIImage(data: readData, scale: 2)
println("\(image) == \(pb.image) == \(readImage)")
}
}
}
