Hide Delete Button While Keeping Swipe to Delete Functionality

2013-11-052015-12-28

Ran into an issue in iOS 7 were the ImageView in a UITableViewCell would resize and cover the delete button after pressing the delete button in editing mode. Here was the workaround I found to just disable the “-” delete button in UITableView’s editing mode but maintain its swipe to delete functionality, just drop this snippet in your TableView’s controller:

– (UITableViewCellEditingStyle)tableView:(UITableView *)TableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath

{

if (self.editing)

{

return UITableViewCellEditingStyleNone;

}

return UITableViewCellEditingStyleDelete;

}

2013-01-142015-12-28

Here are some great instructions from iphonedevsdk.com’s forums about running iOS 5.1 on Snow Leopard and Xcode 4.2.

Great NSXMLParser Tutorial

2012-11-232015-12-28

Here is a very helpful tutorial on using NSXMLParser that was suggested by Ray Wenderlich on his forum. It walks you through using the 3 main parsing methods (didStartElement, foundCharacters, didEndElement) and includes an easy to follow example. I went from knowing nothing about using NSXMLParser to parsing XML from an API request in no time.

Here are a few other resources that helped out once I had my feet under me:

Apple’s Event-Driven XML Programming Guide for Cocoa
Apple’s NSXMLParser Class Reference
CodeProject.com’s article on Parsing XML on the iPhone

Neat trick over on Michael Slater’s blog about how to emulate the look of an iPad mini using a regular iPad. All you have to do is paste some code into the applicationDidFinishLaunching method in your app delegate and your ready to go. Note that this does not emulate the actual resolution of an iPad mini but it will give you a rough idea of how your app will look in the smaller form factor.
