I have one JSON which contain path of images from one local folder of Project as Followed
The issue is i want to get image from that path, How do i achieve it?
I had try to convert String to URL and set URL as Image using Kingfisher Library
let url = URL(string: "/VWiOSProjects/CollageMakerDemo/Development/CollageMaker/CollageMaker/Goodies.xcassets/Goodies-1.imageset/Goodies-1.png")!
cell.imgTool.kf.setImage(with: url)
But it don't work I had Tried this one also
let url = URL(string: "/VWiOSProjects/CollageMakerDemo/Development/CollageMaker/CollageMaker/Goodies.xcassets/Goodies-1.imageset/Goodies-1.png")!
let imageData:NSData = NSData(contentsOf: url)!
let image = UIImage(data: imageData as Data)
cell.imgTool.image = image
NOTE: I can't upload this JSON file on Server, I need to use it Locally
I have solved my issue using fileURLWithPath
let url = URL.init(fileURLWithPath: "/VWiOSProjects/CollageMakerDemo/Development/CollageMaker/CollageMaker/Goodies.xcassets/Goodies-1.imageset/Goodies-1.png")
let imageData:NSData = NSData(contentsOf: url)!
let image = UIImage(data: imageData as Data)
cell.imgTool.image = image
If the images are in Assets(*.xcassets) folder, the you can access it by init(named:) method.
cell.imgTool.image = UIImage(named: "img1")
Actually you no need to store the entire path. You could store image names in array or something.
In my point of view, the best way is to add All Images to *.xcassets folder.(Because you have preloaded 5-10 images)
In case you needs to display it in collection view or TableView,
let imageName = "Goodies-\(indexPath.row)"
cell.imgTool.image = UIImage(named: imageName)
If images are in assets folder itself then go for #Lal Krishna's method. And if they are on server then you should add http:// or https:// and the URL of server followed by JSON's URL.
If still you are not getting it then let me know.

I'm trying to save images using their file paths but every time that I kill the Xcode simulator and restart it, the location of the images changes and my imageView is blank. I know for a fact that the location changes because I print out the file path when I try to pick an image from the photo library and it's different each time.
I access the URL of the UIImage
let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
let url = info[UIImagePickerController.InfoKey.imageURL] as! URL
After which I save the URL as a string to my realm database. I've tried converting it to string via all of these
let imageFilePath = url.relativeString
let imageFilePath = url.absoluteString
let imageFilePath = url.relativePath
but none of them worked. I'm a newbie to Swift so let me know if I've missed any key details needed.
I'm using SDWebImages library to get image for thumbnails. It is working seemlesly.
However when I navigate from video to a controller where I play video, I need to show thumbnail once again. I need an image path to pass to the player.
The problem is if I pass the same URL the player will download the image once again. In order to avoid this behaviour i'm trying to get the image from disc which is already stored there by sdwebimages library.
/// get thumbnail from cache
var thumbnail: String?
if (video?.hasThumbnail) {
let urlString = "https://test.com/image/001.png"
if let path = SDImageCache.shared.cachePath(forKey: urlString) {
thumbnail = path
} else {
thumbnail = urlString
}
}
This is working on a simulator, but NOT on the real device.
Please read more about how to use
imageView.sd_setImage(with: URL(string: "http://www.example.com/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png"))
I am getting an Image as Data from server.To show it I am using UIImage?(data:) to show it.For a specific image application is getting crash because of memory pressure. What could be the reason, how to fix it.
if let imgData = Utils.fetchDataFromDocumentDirectory(imageName:"test.jpg"){
attachmentImgView.image = UIImage(data:imgData)
}
How big is the Image? and are you downloading only 1 image or an array?
This might be caused from the size of the image you are trying to download.
My advice if you are trying to show an image, only giving it the url like so:
let url = URL(string: "http://i.imgur.com/w5rkSIj.jpg")
let data = try? Data(contentsOf: url)
if let imageData = data {
let image = UIImage(data: data)
}
even better you can try to use AsyncImageView 3rd party library where you give it the url of the image and it shows it asynchronously without delays in the app.
Hope this helps!
I have an iMessage app that displays some remote content using SDWebImage. The images are downloaded and cached on disk. After choosing an image, I want to attach it to the message as a plain UIImage (not a MSMessage).
Here's the code I'm using
// image is already downloaded
let cache = SDImageCache.shared()
let key = remoteImageUrl
let fileUrlString = cache.defaultCachePath(forKey: key)!
let fileUrl = URL(string: fileUrlString)!
// image holds the correct UIImage
let image = UIImage(contentsOfFile: fileUrlString)
activeConversation?.insertAttachment(fileUrl, withAlternateFilename: "a funny gif", completionHandler: { (error) in
// error is nil here
print("error: \(error)")
})
Here's what the message looks like
It seems like the Messages framework can't find the image at that path.
Note: after tapping send, I the iMessage app crashes "MobileSMS quit unexpectedly."
I found out that I needed to use
let fileUrl = URL(fileURLWithPath: fileUrlString)
Hope this helps someone else
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
