screenshot : http://hpics.li/3c45def
now I want to display the logo stored on the server, I tried to integrate the tableview imagedownloader but I failed, someone has an idea of where to start
Thank you
You can use NSURLRequest to download the raw data for the image from the server. Once downloaded you can set the image in your tableview.
You start by having a look at this post.

You can download like this:
Create WKWebView
Connect outlet
Conform WKUIDelegate in your controller
Create request with your wiki link
Set webView uiDelegate to self
Load from request
You should configure content for UI :)
Svg images doesn't get directly supported in iOS apps. you simply need to add on a third party pod extension in order to use the svg images in app.
For example : https://github.com/pocketsvg/PocketSVG
Try using this PocketSVG.
I will like to know how to take a screenshot of the iOS host app with the use of a share/action extension.
My use case is as follows:
use the Safari browser to access a webpage (https such as gmail)
tap on the Share button and select the extension
the extension will take a screenshot of the current webpage
An working example for this use case is the Awesome Screenshot iOS app.
I had tried the following methods
reload the baseURI (loadRequest) on a UIWebView/WKWebkit (would not be able to access https contents such as Gmail). So not doing any reload (Awesome Screenshot is not doing a reload btw)
Used the ExtensionPreprocessingJS to obtain the DOM contents through the arguments.completionFunction function. I could not extract the document.body here although i could get the source etc. loadHTMLString with the baseURI will mess up the presentation layer.
Used html2canvas in the ExtensionPreprocessingJS to obtain an image and appended it to the host app's webpage as a child but do not know how to extract it. Also, the image got lost for some webpages such as Gmail.
Mobile Safari does not have the visibleContentsAsDataURL method.
I think a viable approach will be to use the html2canvas in the ExtensionPreprocessingJS but how do I save this image somehow?
Edit: So the below works in the Simulator but does not work on the device. I'm presently looking for a solution as well.
Here's a solution that I think the Awesome Screenshot app uses:
func captureScreen() -> UIImage
{
// Get the "screenshot" view.
let view = UIScreen.mainScreen().snapshotViewAfterScreenUpdates(false)
// Add the screenshot view as a subview of the ShareViewController's view.
self.view.addSubview(view);
// Now screenshot *this* view.
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, false, 0);
self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
// Finally, remove the subview.
view.removeFromSuperview()
return image
}
I want to load image in card view with other data like title and desc.
I am uaing php to get result as json response which is working and also i am able to set data to textview and pass from one activity to other !
Only problem i am facing is in setting image in image view.
i can add image manually by making listview obj and storing link in ArrayList obj
Like obj.add(R.drawable.feature1.jpg)
How to do it dynamically from the json response i am getting ?
Sorry if i sound confusing as i am new to android and just want to make a image gallery where first i will display list of albums and after clicking one of albums all images from that albums are loaded and displayed.
{"products":[{"mid":"1","title":"Demo Video 1","link":"https:\/\/m.youtube.com\/watch?v=PCwjNfSM-U","mediaCreatedOn":"2015-08-30 18:59:18","mediaUpdatedOn":"0000-00-00 00:00:00"},{"mid":"2","title":"Demo Video 1","link":"https:\/\/www.youtube.com\/","mediaCreatedOn":"2015-08-30 18:59:18","mediaUpdatedOn":"0000-00-00 00:00:00"}],"success":1}
The above is the output from server side where only the youtube link is replaced by server img location.
Thank you for reading, have a nice day ahead :)
1:You can store image to database Example:mysite.com/img/34324234342.png (phpMysql)
2:And you can get image from php rest service (Only image link)
3:For load image from link , you can use picasso library (android)
4:If you want image with text, you can use custom listview
Example xml for restful service.
<myimage>
<title>abc</title>
<ipath>mysite.com/img/34324234342.png</ipath>
</myimage>
I'm trying to get a UIImage of a UIWebView, I can do this fine using renderInContext:. However before I generate the image I would like to update the UIWebView with some HTML code, the trick is the UIWebView is hidden. Right now, I can not get the updated version of the web view to render in the UIImage, just the old one.
Are you waiting until the UIWebView re-renders before querying it again? Loading HTML into a UIWebView does not immediately update the view. You need to wait for webViewDidFinishLoad:. This is true even if the HTML is a simple string with no external references.
