iOS Declares from the Xojo Community

Our user community has been busy enhancing the capabilities of Xojo for iOS with Declares!

We have been quite pleased with the feedback we’ve received about Xojo iOS, but we are commonly asked when Xojo will support a specific iOS feature that it does not yet have. We will be adding new iOS features with each release, but you may not have to wait for us to add a feature. With a bit of knowledge about CocoaTouch and the use of the Declare command in Xojo, there are many things you can take advantage of today.

Guest Post: Solving Sandboxing Issues and Improving Xojo Apps With Ohanaware’s Sandbox Kit

Sam Rowlands has been developing Xojo apps since 1997. He and his wife, Joy Sha, make up Ohanaware and they have been building award winning apps since 2008, notably Funtastic Photos, HDRtist and Shine. Sam is an active Xojo developer and he also offers App Wrapper, which simplifies the process of preparing applications for submission to the Mac App Store and deploying on web sites, in the Xojo Third Party Store.

What is the App Sandbox and why is it a chore?

The App Sandbox is a great end user security concept. The Sandbox governs what an application can and cannot do. This means that a virally infected word processor, cannot go on to infect other applications nor rampantly damage files on the users disk. It can however affect files which the user has created or opened within the word processor.

Iterators

One feature that was added in Xojo 2014r3 that I haven’t seen much discussion about yet is iterators. In short, iterators are a way to make classes useable with the existing For Each loop feature.

Coding To Be Lazy

I know a lot of people like to write their local variable declarations like this:

dim i, i, j as integerdim k as double, s as string, b as boolean

Personally, I don’t and the reason is not that I like typing…

Oh, Say Can You C?

There is a “bug” here, can you spot it?

dim s as string = "abc" + chrb(0) + "def"
dim c as cstring = s
if s = c then
  msgbox "Yay our software works as we expected!!!!"
else
  msgbox "BOOOOOO!!!!"
end if
