This will ensure that the indices are correct when you attempt to update rows.Update 4/7:- For notifications (static and dynamic), the controller's background color should be set to 14% white and the insets should be set to custom values of 0 for all sides. This will give the intended system default look.- If you are using openParentApplication:reply:, make sure you create a background task immediately upon entering application:handleWatchKitExtensionRequest:reply:.

On this page you will find links to resources for developers and scripters alike, including training materials and code examples. Enjoy!THE LANGUAGE OF AUTOMATIONAppleScript is an English-like language used to create script files and applets that control the actions of the computer and the applications that run on it. AppleScript scripts can “think” and make decisions based on user-interaction or by parsing and analyzing data, documents or situations. With support integrated into hundreds of Apple and third-party applications, AppleScript provides motivated customers an approachable way to address their specific automation requirements by writing their own scripts or using those developed by others.THE BENEFITS OF APPLESCRIPTResearch has shown that a primary requirement of customers, professionals, and businesses alike is for customizable automation tools to en

Hi all,We had a version rejected from the App Store. Problem fixed, and we created a new version. Old version was 2.0.1, new version is 2.1. So, ITC has the 2.0.1 rejected version under Versions. No problem. I upload the new version from Xcode, it shows up in the ITC Pre-release tab, I change the app description and the manual version number, but under Build, it shows 2.0.1, not 2.1. There's no way to change it to 2.1. From what I read, there's supposed to be a + next to builds to allow me to select the build to be tested, but it's not there. I put a note in the developer's note section explaining the problem, but I'm a bit nervous that we're going to wait a week only to be told that there was a problem when I did everything (seemingly) correctly. Anyone else know what to do about this?

Would like to make a thread for currently unstable apps with this version of the beta.Has anyone experienced app crashes at this point?

Hi!I am creating a pair of iOS apps that will use AirDrop to move files between them. These files are either PNG, XML, or HTML files, and they are represented as file-based URLs when passed to the UIActivityViewController.When I select the PNG file to transmit and I have launched the receiving app (on another iOS device), the Photos app opens on the receiving device. My receiver app is set up to import the correct UTI and to open the correct document type, but its AppDelegate application:openURL:sourceApplication:annotation: method is never executed.Is there a list of AirDrop file types and their mappings to the Apple iOS apps that will automatically open them? Thanks,Karl G. Kowalski
