iOS 9.0 SDK provides new way to select and display proper localized string variation depending on screen width.
Apps run on different screen sizes and different orientations. Apps present
different texts, sometimes longer that not fit a screen width and sometimes you
want to display text that perfectly fit in just one line. There is new method
which helps us with this. It uses stringsdict file and new
Let’s say you want to display “Forgotten Your Password? Get password Help.” label with touchable “Help” word. On some screens and layouts it might perfectly fit, but on some smaller it might be too long. In that case you would like to display “Forgot password? Get password Help.” which is a bit shorter. And let’s pretend there is another version of screen which is a bit shorter than previous (e.g. Apple Watch) and then you would like to display the shortest one: “Forgot password? Help.”.
For strings with length variations, such as from a stringsdict file, this method returns the variant at the given width. If there is no variant at the given width, the one for the next smaller width is returned. And if there are none smaller, the smallest available is returned. For strings without variations, this method returns self. The unit that width is expressed in is decided by the application or framework. But it is intended to be some measurement indicative of the context a string would fit best to avoid truncation and wasted space.
What you need to do is to create stringsdict file and add dictionary like this:
Then, to get one variant of these above you must call
with key “Forgot Password” and next
to get variant for specified width. The example shows how to get string that
fits 100px width.
This addition is nice, it will simplify a bit code where there is necessity to
deal with such strings. I don’t like a bit that the new API is available only
String so you have to
do extra cast.
