New properties help you determine if your user is using an iPhone, an Android
device, a Windows PC, an iPad or a Mac. Use this feature to do things like
only showing a text box if the user is running an iPhone or changing app
colors based on the operating system.
You can now pad numbers with leading zeroes by setting a minimum number of
integer digits in the inspector. With a minimum number of four digits, 23 is
formatted as 0023. As a bonus, we show how to accomplish the same thing using
formulas and share some news regarding the venerable IF function.
Some countries use a 12-hour clock in everyday life, but a 24-hour clock in
some professions. Our new release enables you to use a language that normally
uses a 12-hour clock and still use a 24-hour clock for some time fields.
Assign subject lines to reports you send from apps with our new release. You
can determine the subject line using a formula, enabling you to include parts
of the report in the subject line itself. Use this feature in conjunction with
labels or rules in your e-mail client to automatically sort incoming reports.
What if you want to limit the number of characters users can type in a text
field? This tip uses validation to alert your users if they type too much text
and show you how to include only a limited number of text field characters in
Reports sent by your users normally contain all fields of your app or only the
fields of the current panel. This tip demonstrates how you can select
precisely what fields to include, which cuts down on the size of the reports.
Can a formula be used to send reports to many e-mail recipients and can a
button both open a report and send it? Matt posed this question and received a
reply from our co-founder David, who shared some of our future plans for
enabling buttons to execute formulas.
Add steppers to number fields to make it easy to change their values using
plus and minus buttons. Sliders take up more space, but make it even easier to
experiment. There are also new formula functions, improved support for
embedding apps in web sites and a rewritten tour template.
If only some users need to use a large number of fields, start off by showing
only a few and give users the ability to add or remove fields using plus and
minus buttons. We demonstrate this technique using a sample app that
calculates a grade point average (GPA).
