How to get the QLPreviewView's content size? - objective-c

I would like to know how I can get the QLPreviewView content size? It seems that the API doesn't have any methods to get it. Thanks.

QLPreviewView won't give you that.
But since you are supposed to give QuickLook a path to reach files, you can get yourself size of them with file manager.
Take a look at this topic for example.

MacOS/Safari double extensions when using ImageResizer

We are converting large PNG images to JPEG using ImageResizer (https://imageresizing.net/). It's works great with ?format=jpg and they are delivered with the correct content type and all.
When downloading these images they are named image.jpg in all browsers except Safari. Here it asks the user if they want to go with .jpg or with .png. It also saves the images as image.png.jpg which is confusing for some users.
I read something about Content-Disposition header, but I think that's for direct download, not for right click and choosing Save as. I also don't know if it would be possible to add it without creating some kind of middle layer and probably lose performance.
Ideas? Thanks <3
I don't think there is a solution to this, as it is in the browser's control.

How to take screenshot and share using react-native?

I have used react-native-view-shot to take screenshots which return screenshot local URL. and used react-native-share to share on other apps like whats-app etc.
But how can share screenshot because react-native-view-shot give only local path.
You'll probably need to get the base64 of your image. Unless they've updated things, I have used a workaround I found in the past

This is an NSBrowser. Read Apple's Browser Programming Topics for even more info. I think their browser may be customized to get the full behavior seen in the Finder.

Wikimedia API - How can I get all resolutions of an image

I want to copy images from a wikipedia page.
When I do it manually, I click on the picture, and then select the resolution that fits my need (width as close to 400).
Now, I am using the Wikimedia API to get the images.
But they give me only one resolution.
I saw a similiar question in Stackoverflow, but the answer was to use the iiurlwidth=400
I used it, and it does not do it (it is probably only for vector pictutres).
OK, I found that the answer to use the iiurlwidth=400 was correct, but the reply is not in the "url" item, but in the "thumburl" item,which is in the right width.

Text reading experience in iOS app

I want to implement a great text reading experience in my app, similar to "Pocket", that would look a lot like this:
Basically, I'd like to have control over the text font size and font family while loading local HTML files in a UIWebView.
Could anyone point me to the right direction? Are there any frameworks or libraries out there that provide the base for such experience?
Thanks in advance.
A simple answer is: don't. Instead load it into a UITextView. You can easily change the font size with it, as on HTML you would have to modify the file instead of calling 1 line of code.
