Cannot change YouTube video quality at all (always starts with “medium”) with iOS's WebView

由 廉价感情. 提交于 2019-12-13 05:42:12
问题 I tried to put player.setPlaybackQuality('hd720'); in onReady and onStateChange but nothing of that works (iPad or iPhone always starts with medium quality and it can't be changed) Even setting small quality doesn't change anything, these functions just doesn't work with iOS's UIWebView/WKWebView I also tried to play with size of elements in html just for fun (set hardcoded size, like 1920x1080px) but it also didn't work: <head> <style> * { margin: 0; padding: 0; } html, body { width: 1920px;

由 梦想的初衷 提交于 2019-12-13 05:21:11
问题 I am at a loss. I have a UIViewController with a UIWebView in it. When I run the application the UIWebView is never instantiated. Everything else comes up fine. Has anyone seen this before? Rob 回答1: I found the problem. The UIWebView does not instantiated UNTIL it is displayed. I was trying to load the website before I pushed the view controller into the navigation controller. 来源： https://stackoverflow.com/questions/9095529/xib-will-not-create-uiwebview-and-is-always-nil

由 ≡放荡痞女 提交于 2019-12-13 05:12:35
问题 I have web content inside a UIWebView in my app. My goal is to have all links open normally inside the app, but any links starting with "http://maps", get opened in safari, so they can in turn be opened in the external iphone maps app. If you have a solution for this problem stop reading now, below I'm going to propose my solution. Currently all links are opened inside the app, so http://maps links open to m.google.com inside the app. The solution I'm thinking of involves this code which uses

How to draw a non-rectangle UILabel with paragraph truncation at the end?

由 五迷三道 提交于 2019-12-13 04:46:28
问题 I need to show a body of text similar to the one shown below and limited to the red non-rectangular area. Rob's answer to this question pretty much answers my question as well, but I also need to truncate at tail of the paragraph when the text is too long. Extra question: is it also possible to set minimum font size similar to UILabel? 回答1: Try using NSString::sizeWithFont:constrainedToSize method which is documented here. You can specify the fontsize and maximum size for the text. You can

Tap and hold save image from UIWebView

由 亡梦爱人 提交于 2019-12-13 04:35:42
问题 I want to be able to save an image to the photos app from a UIWebView when the user taps and holds on the image. I've managed to save an image from a UIWebView when I was programming in objective-c however now as I'm learning swift it seems to be kind of different. This is how I did it back in Objective-C: -(IBAction)saveWeb:(id)sender { UIGraphicsBeginImageContext(webview.frame.size); [self.webview.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage

Confirm UIWebView link click

由 被刻印的时光 ゝ 提交于 2019-12-13 04:33:35
问题 I know that you can detect link clicks in a UIWebView with: UIWebViewNavigationTypeLinkClicked and easily access the url, i also know that you can: return YES or return NO if you want to advance to the next page or not...but is there a way to use a UIAlertView to determine if the use wants to return YES or NO? 回答1: This can be done. When you get the link in the webView:shouldStartLoadWithRequest:navigationType: delegate method, save off the URL, display the alert view, then return NO from the
