Ok so in my iOS app there is a screen with an AVPlayerViewController that takes care of playing videos. When this video is played it fills the entire screen however on some videos they video seems stretched as if it is being forced to fit. Is there any way to make the video fit the entire screen without losing the aspect ratio.
The code below is what I use to lay out the AVPlayerController. I figured some error here is the cause of this flaw in aspect ratio.

self.view.addSubview(blurView)
// Indicator for loading
let indicatorFrame = CGRect(x: view.center.x - 20, y: view.center.y - 20, width: 40, height: 40)

playerController.videoGravity = AVLayerVideoGravity.resizeAspectFill.rawValue
playerController.view.frame = view.frame
// spb.durations = durations
}
Any help is greatly appreciated
to keep the video aspect ratio in the defined view frame use
AVLayerVideoGravity.resizeAspect.
For the current case replace
playerController.videoGravity = AVLayerVideoGravity.resizeAspectFill.rawValue
to
playerController.videoGravity = AVLayerVideoGravity.resizeAspect
I am not sure about it but use this :
playerController.view.frame = view.bounds
Instead of this:
playerController.view.frame = view.frame
The AVLayerVideoGravity.resizeAspectFill.rawValue should do what is says and I never had a problem with it. However, I use the bounds instead of the frame and I remember getting problem when using the frame.
You also have AVLayerVideoGravity.resizeAspect.rawValue that will fit the video instead of filling it.
You can also try setting the frame before the video gravity.
By setting app's AVAudioSession's category to AVAudioSessionCategoryPlayback with option mixWithOthers, will make sounds from video in UIWebView be mixed with third party background music (such as Spotify).
But it do NOT work at all once switch to WKWebView. Code sample:
let audioSession = AVAudioSession.sharedInstance()
do {
try audioSession.setCategory(AVAudioSessionCategoryPlayback, with: .mixWithOthers)
try audioSession.setActive(true)
} catch {
print(error)
}
/*
// Mixed background music & video sound in web works with UIWebView
let webview = UIWebView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 300))
self.view.addSubview(webview)
webview.loadRequest(URLRequest(url: URL(string: "http://www.ultimedia.com/deliver/generic/iframe/mdtk/01509739/src/8l50lp/ad/yes")!))
*/
// Mixed background music & video sound in web do NOT work with WKWebView
let webview = WKWebView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 300))
self.view.addSubview(webview)
webview.load(URLRequest(url: URL(string: "http://www.ultimedia.com/deliver/generic/iframe/mdtk/01509739/src/8l50lp/ad/yes")!))
// end of viewDidLoad
Code above tested on Xcode 8.2.1, iOS 10.2.1
Any idea or workaround would be really helpful.
Many thanks.
I want to show a video of a topic in top half of the view and its matter in textview in the bottom half of the view. For that video control i want to have the features like play,pause,stop,ff etc. Also i want to play it from local resource as my web services hasn't been setup yet. pls suggest a good solution
I have tried UIWebView and added constraints to webview and textview but for some reason the web view is not showing the video correctly. below is my code
let purl = NSURL(fileURLWithPath: "/Users/Rohit/Desktop/videos/demo/demo/video1.mp4") webView.loadHTMLString("<iframe width = \" \(webView.frame.width) \" height = \"\(webView.frame.height)\" src = \"\(purl)\"></iframe>", baseURL: nil)
webView.backgroundColor = UIColor.green
webView.mediaPlaybackRequiresUserAction = true
webView.scrollView.isScrollEnabled = true
webView.isUserInteractionEnabled = true
Import AVFoundation and AVKit
Then play the video using an URL object (in Swift 3 NSURL is renamed to URL)
let player = AVPlayer(URL: URI)
let controller = AVPlayerViewController()
controller.player = player
self.addChildViewController(controller)
let screenSize = UIScreen.main.bounds.size
let videoFrame = CGRect(x: 0, y: 10, width: screenSize.width, height: (screenSize.height - 10) * 0.5)
controller.view.frame = videoFrame
self.view.addSubview(controller.view)
player.play()
You can use AVPlayerLayer and give it bounds.
private func inits() {
//let rootLayer: CALayer = self.layer
// rootLayer.masksToBounds = true
avPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.bounds = self.bounds
// avPlayerLayer.backgroundColor = UIColor.yellowColor().CGColor
self.layer.insertSublayer(avPlayerLayer, atIndex: 0)
}
I request a Website with this code
let requestObj = NSURLRequest(URL: url)
myWebView.loadRequest(requestObj)
print (myWebView.scrollView.contentSize.height) //1
print (myWebView.frame.size.height) //2
The code always return 1000.0 when the real size of the website is much more than that. Is there a way to get the real size ? I want to show the hole content of a WebView without the need of scrolling within the WebView.
You need to use the webViewDidFinishLoad delegate method, this answer was originally founded here How to determine the content size of a UIWebView?
In your viewDidLoad method do something like this
override func viewDidLoad() {
super.viewDidLoad()
self.webView.loadHTMLString(component.html, baseURL: nil)
self.webView.scrollView.isScrollEnabled = false
self.webView.scrollView.bounces = false
self.webView.delegate = self
self.delegate = delegate
}
public func webViewDidFinishLoad(_ webView: UIWebView)
{
var frame = webView.frame
frame.size.height = 1
webView.frame = frame
let fittingSize = webView.sizeThatFits(CGSize(width: 0, height: 0))
frame.size = fittingSize
webView.frame = frame
webView.scrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
self.delegate?.heightHasChanged(indexPath:self.indexPath, newHeight: frame.height)
self.loadingView.isHidden = true
self.loadingActivityIndicator.stopAnimating()
}
I hope this helps you, best regards
I am loading a PDF into a UIWebview and I changed the background color to clear and set opaque to false. However now there is a padding or margin in my UIWebView that I would like to remove so the UIWebview is the screen.
I created a UIWebview like so:
let webview = UIWebView()
webview.frame = self.view.bounds
webview.scrollView.frame = webview.frame
webview.userInteractionEnabled = true
webview.scalesPageToFit = true
webview.becomeFirstResponder()
webview.delegate = self
webview.scrollView.delegate = self
webview.opaque = false
webview.backgroundColor = UIColor.clearColor()
self.view.addSubview(webview)
webview.loadRequest(NSURLRequest(URL:url))
webview.gestureRecognizers = [pinchRecognizer, panRecognizer]
and I applied this to the webViewDidFinishLoad method
func webViewDidFinishLoad(webView: UIWebView) {
let padding = "document.body.style.margin='0';document.body.style.padding = '0'"
webView.stringByEvaluatingJavaScriptFromString(padding)
}
but there is still a padding or margin, it looks like this:
How do I fix this?
The Reason why I need this fixed is because I am going to be saving this UIWebView as a PDF and when I save it, that extra spacing is there also, here is my PDF generate code:
func drawPDFUsingPrintPageRenderer(printPageRenderer: UIPrintPageRenderer) -> NSData! {
let data = NSMutableData()
UIGraphicsBeginPDFContextToData(data, CGRectZero, nil)
UIGraphicsBeginPDFPage()
printPageRenderer.drawPageAtIndex(0, inRect: UIGraphicsGetPDFContextBounds())
UIGraphicsEndPDFContext()
return data
}
and more
let screenHeight = appDelegate.webview!.scrollView.bounds.size.height
let heightStr = appDelegate.webview!.scrollView.bounds.size.height
let height = heightStr
let pages = ceil(height / screenHeight)
let pdfMutableData = NSMutableData()
UIGraphicsBeginPDFContextToData(pdfMutableData, appDelegate.webview!.scrollView.bounds, nil)
for i in 0..<Int(pages)
{
if (CGFloat((i+1)) * screenHeight > CGFloat(height)) {
var f = appDelegate.webview!.scrollView.frame
f.size.height -= ((CGFloat((i+1)) * screenHeight) - CGFloat(height));
appDelegate.webview!.scrollView.frame = f
}
UIGraphicsBeginPDFPage()
let currentContext = UIGraphicsGetCurrentContext()
appDelegate.webview!.scrollView.setContentOffset(CGPointMake(0, screenHeight * CGFloat(i)), animated: false)
appDelegate.webview!.scrollView.layer.renderInContext(currentContext!)
}
UIGraphicsEndPDFContext()
Setting the scroll view frame to the web view frame will have no effect while the web view is at the origin and an unwanted effect otherwise.
Adjust the scroll view contentInset:
// set t,l,b,r to be negative CGFloat values that suit your content
webView.scrollView.contentInset = UIEdgeInsetsMake(t,l,b,r);
This appears to fix my issue, not sure how well it work with other PDF documents (Portrait) mine is Landscape and it works fine.
appDelegate.webview = UIWebView()
appDelegate.webview!.frame = CGRect(x: 0 - 8, y: 0 - 8, width: self.view.bounds.size.width + 14, height: self.view.bounds.size.height + 14)
appDelegate.webview!.scrollView.frame = CGRect(x: 0 - 8, y: 0 - 8, width: self.view.bounds.size.width + 14, height: self.view.bounds.size.height + 14)
and then for saving the PDF
func createPdfFromView(aView: UIView, saveToDocumentsWithFileName fileName: String)
{
let pdfData = NSMutableData()
UIGraphicsBeginPDFContextToData(pdfData, CGRect(x: 0 + 8, y: 0 - 8, width: aView.bounds.size.width - 17, height: aView.bounds.size.height - 117), nil)
UIGraphicsBeginPDFPage()
guard let pdfContext = UIGraphicsGetCurrentContext() else { return }
aView.layer.renderInContext(pdfContext)
UIGraphicsEndPDFContext()
if let documentDirectories = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first {
let documentsFileName = documentDirectories + "/" + fileName
debugPrint(documentsFileName)
pdfData.writeToFile(documentsFileName, atomically: true)
}
}
Please let me know if I am doing anything wrong
It worked for me to apply negative content insets. This works on iOS 11 and 10, on Swift 4:
webView.scrollView.contentInset = UIEdgeInsets(top: -8, left: -8, bottom: -8, right: -8)
I am not sure if you have found the answer but as a quick work around you can give pre adjusted constraint .
lets say if yours padding space is 10px from all 4 sides and if its always a constant
the work around is :
Give -10 space for the webView around it , also make don't forget to add a superview to your webView without the -10px side constraints and mark the superview
clipsToBounds = true
clipSubViews = true
This example gives a top spacing of 64 to allow for a nav bar.
let webView: UIWebView = UIWebView()
webView.frame = self.view.bounds
webView.scrollView.frame = webView.frame
webView.scrollView.contentInset = UIEdgeInsetsMake(64,0,0,0)
I don't know why I come here so many times but google never sends me through to the actually answered question. For anyone with the same problem here is the actual answer: https://stackoverflow.com/a/2442859/3393964
The problem is that browsers add a default margin, a simple fix is adding this:
body { margin: 0; padding: 0; }
