Problem with multilines text on iOS 7

#1

Hi,

In my app, I use display.newText()  to create a multiline text, and I specified a width and set height to 0 as it is explained in the documentation below.

Optional arguments to enable multi-line text. Text will be wrapped at width and be cropped at height. Set height to 0 and the height will change according to amount of text.

I currently test my app on multiples devices with different iOS versions.

Everything is ok… Since iOS 7!

I noticed that with iOS 7, on any devices, it doesn’t work :

No more multilines, only one line is displayed and cut at width pixels.

Thanks for your help

Best,

Olivier

Note that

  • I use Version 2013.1218 (2013.9.28)
  • It works fine on Corona simulator.

Thanks again

Hi @oromanetti,

Are you setting both width and height to 0? I think the width should be something greater than 0… it’s only height that may be set to 0 to give a “flexible height” box.

Hi Brent

Thank you for your mail.

No I didn’t set width to 0.

My width parameter value is 400.

As I said, everything worked fine before iOS 7.

With iOS 7 devices, the “flexible height” doesn’t work anymore for me.

Anyone with same problem?

Hi Olivier,

Which build # are you using for this test? Can you also show me the code you’re using?

Hi Brent

I use Version 2013.1218 (2013.9.28)

I did a very simple example to show you my problem :

local myText = "The 'clef' at the beginning of the staff determines the names of the notes." local helpText = display.newText(myText, 0, 0, 200, 0, "Arial", 16 ) helpText:setReferencePoint(display.CenterReferencePoint) helpText:setTextColor(255) helpText.x = display.contentCenterX helpText.y = 50

Everything work fine in the simulator, you can see all the text.

If you try this little example on a device with iOS 7 you will see that the text is cut, sometimes on the first line, sometimes on the second line. 

For me, on my iPad Retina with iOS 7, I can see on my screen :

____________________________

The ‘clef’ at the beginning of

the staff determines the

It’s a big problem for me because I use a lot this “flexible height” stuff on my app.

Thanks for your help.

Hi Olivier,

I tried the exact code you show on my iPad Retina 4th-gen with iOS7, and the text appears as expected… it’s not cut off, and I can read the entire sentence.

I used Corona build #1225

Retina iPad

iOS 7.0.2

config.lua setup at 640x960 “letterbox”

You may consider using non-flexible boxes with a very high height setting (like 2000), put the text inside, and then align them along a top-center point, not a center point. You would need to experiment with this, however, and see how it works in your app.

I hope It will be ok.
