Sometime you need to know if a UITableViewCell is completely visible and for those times there’s this handy UITableViewCell category. //Place in UITableViewCell Category - (BOOL) isCompletelyVisible { // For parents category see pdenya.com/g/uiview_parents UITableView *tableview = (UITableView *)[self parents:[UITableView class]]; CGRect rect = [tableview rectForRowAtIndexPath:[tableview indexPathForCell:self]]; rect = [tableview convertRect:rect toView:tableview.superview]; BOOL completelyVisible = CGRectContainsRect(tableview.frame, rect); return completelyVisible; } I’d like to mention that you can skip this check entirely if your goal is to make sure a cell is completely visible. With UITableViewScrollPositionNone scrollToRowAtIndexPath:atScrollPosition:animated: doesn’t scroll at all if the cell is totally visible and in other cases it scrolls as little as possible which is usually the ideal behavior. ...

HelloSign for Gmail is a browser extension for Chrome, FireFox and Safari that lets users fill out and sign documents without ever leaving Gmail. The user clicks the sign button next to an attachment and the file is uploaded to HelloSign and the HelloSign editor is opened in a lightbox for the user to sign and make annotations. When the user clicks Continue the iframe closes, a compose window opens in Gmail (as if the user had clicked reply) and the signed document is attached, ready to be sent. ...

Whenever you have a modal element that outside touches should cancel a few things need to happen: Touches inside the modal element should behave normally Outside touches should not trigger touch events on tappable elements Outside touches should trigger a handler to close the modal In my case I was swiping a UITableViewCell and revealing a controls view that should close if any other UITableViewCell is tapped. hitTest:withEvent - The easiest method Touch events bubble down from the root view rather than up from the target view which makes this a bit easier. On whichever view needs to capture the touch events, we need to override hitTest:withEvent: to return nil and call a function whenever a modal is open and a view other than the modal is tapped. I overrode this method in my UITableView’s superview. ...

There’s a few plugins for hiding the WordPress admin bar that shows up on top of your site when you’re logged in but it seems like overkill. If you don’t care about preventing it from loading you can drop this in your stylesheet at wp-admin/themes.php?page=editcss to hide it. html { margin-top: 0!important; } #wpadminbar { display: none; }

“⌘ + w” in VMWare has been frustrating me for months. The situation goes something like this: I have a VM open and active I hit “⌘ + W” like an idiot My VM starts suspending, forcing me to wait for suspending and resuming to complete I needed a way to stop myself from accidentally closing my VMs multiple times per week. The Fix It’s pretty simple, we just remap “⌘ + w” to something else like “⌘ + ⇧ + w” in System Preferences. First, open System Preferences and go to Keyboard > Keyboard Shortcuts > Application Shortcuts. Use “File->Close” as the menu title and VMWare Fusion as the application. ...

Here’s an if chain that figures out the relative time. The current version suites my needs but it’s easy to modify. //print date to countdown_label NSCalendar *calendar = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease]; NSDate *fromDate = [NSDate date]; NSDate *toDate = [user filtered_until]; NSDateComponents *components = [calendar components:NSDayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit fromDate:fromDate toDate:toDate options:0]; NSString *countdown_text = @""; if (components.day > 1) { countdown_text = [NSString stringWithFormat:@"%i days", components.day]; } //1d 4hrs else if (components.day > 0 && components.hour > 1) { countdown_text = [NSString stringWithFormat:@"%id %ihrs", components.day, components.hour]; } //1d 1hr else if (components.day > 0 && components.hour == 1) { countdown_text = [NSString stringWithFormat:@"%id %ihr", components.day, components.hour]; } //1 day ..this probably won't happen else if (components.day > 0 && components.hour == 0) { countdown_text = [NSString stringWithFormat:@"%i day", components.day]; } //12 hours else if (components.hour > 1) { countdown_text = [NSString stringWithFormat:@"%i hours", components.hour]; } //1 hour else if (components.hour == 1) { countdown_text = @"1 hour"; } //48 mins else if (components.minute > 1) { countdown_text = [NSString stringWithFormat:@"%i mins", components.minute]; } //1 min else if (components.minute == 1) { countdown_text = @"1 min"; } //0 min or less else { countdown_text = @"now"; }

The print hotkey is not useful to me. If it opened immediately and was immediately dismissible with esc it would be less frustrating but as it is every time the print dialogue opens I need to wait several seconds before I can dismiss it regardless of which app it’s in. “⌘+P” has been frustrating me for a while, being next to “⌘+[”. Now that i’m using Sublime Text 2 as my editor of choice it’s worse because “⌘+P” is ST2’s default quick open hotkey. ...

There are a few common issues with saving PDFs in Adobe Illustrator. I experienced these with CS5 (5.1 specifically) but while looking for a fix I saw reports of the same errors from users with CS2, CS3, CS4, and CS6 as well. Commond errors include: “This file cannot be found.” when trying to save a PDF in Illustrator Saved PDFs coming out blank white or empty with file sizes 500k+ This file cannot be found ...
