I'm looking at replacing ALAssetsLibrary with Photos framework in my app. I can retrieve photos, collections, and asset sources just fine (even write them back out), but don't see anywhere to access the metadata of the photos (the dictionaries such as {Exif}, {TIFF}, {GPS}, etc...). ALAssetsLibrary has a way. UIImagePickerController has a way. Photos must have a way too. I see that PHAsset has a l

I've been using SDWebImage on my iPhone app to handle all of the image loading. I am using a placeholder image, and I want to crossfade or fade in the new image once it loads. I am using a success block to set the image, and it is working great. No matter what I try, the image will not fade in though. I've tried sending the animation code back to the main thread, but that didn't help either. It ju

Suppose I have this HTML element: <div id="parent"> Hello everyone! <a>This is my home page</a> <p>Bye!</p> </div> And the user selects "home" with his mouse. I want to be able to determine how many characters into #parent his selection starts (and how many characters from the end of #parent his selection ends). This should work even if he selects an HTML tag. (And I need it to work in all browser

I have contentEditable element (can be p, div, ...) and I would like to get caret (cursor) position in it. I can normally achieve it with this piece of code: var position = window.getSelection().getRangeAt(0).startOffset; This works fine while the element contains just text. But when the element contains some HTML formatting, the returned position is relative to caret position within included HTML

Yes apple has disabled this feature (among others) in UIWebViews and kept it for Safari only. However you can recreate this yourself by extending this tutorial, http://www.icab.de/blog/2010/07/11/customize-the-contextual-menu-of-uiwebview/. Once you've finished this tutorial you'll want to add a few extra's so you can actually save images (which the tutorial doesn't cover). I added an extra notifi

I need to resize some elements in relation to the height of the iPhone's Status Bar. I know that the status bar is usually 20 points high but this isn't the case when it's in tethering mode. It gets doubled to 40. What is the proper way to determine it's height? I've tried [[UIApplication sharedApplication] statusBarFrame] but it gives me 20 x 480 in landscape which is correct but then it gives me

I'd like to attach the location of the user to a TWRequest. I've tried to modify the url (with something like this: "http://api.twitter.com/1/statuses/update.json?lat=37.76893497&long=-122.42284884") but the response was "401 Unauthorized" or "400 Bad Request". My TWRequest: TWRequest *postRequest = [[TWRequest alloc] initWithURL: [NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.jso

I know this is possible as Tapbots Pastebot does this. I am trying to grab the UIPasteboard when my iPhone app is running in the background and add it to a UITableView just as Pastebot does but I am also trying to shorten the link, if its a URL and copy that back to the UIPastboard so its ready for the user to paste anywhere. Now Pastebot apparently runs in the background by playing an audio file

The UINavigationBar and UISearchBar both have a tintColor property that allows you to change the tint color (surprising, I know) of both of those items. I want to do the same thing to the UITabBar in my application, but have found now way to change it from the default black color. Any ideas?

Modern approach The modern way, for the entire navigation controller… do this once, when your navigation controller's root view is loaded. [self.navigationController.navigationBar setTitleTextAttributes: @{NSForegroundColorAttributeName:[UIColor yellowColor]}]; However, this doesn't seem have an effect in subsequent views. Classic approach The old way, per view controller (these constants are for
