This version cures numerous bugs and has been tested especially carefully in two areas: Media Uploader and Post Write/Edit. says Isaac Keyet writing on the WordPress for iOS website.
“We think we’ve also fixed many of the issues around the Media Uploader (before if you uploaded many pictures it sometimes wouldn’t work or even crash the app). Now we’re able to upload tons of images without the app crashing, we’re really hoping it works better for all of you as well.”
WordPress for iOS is the app that lets you write posts, upload photos, edit pages, and manage comments on your blog from your iPhone, iPad, or iPod touch. With support for both WordPress.com and self-hosted WordPress (2.92 or higher), users of all experience levels can get going in seconds. WordPress for iOS is now optimized to take advantage of the iPad’s new user interface. Download it from the App Store.
