Description

Because of the new dark mode in xCode 11 i wanted to set the hintTextColor for all my TextField's but setting:

"TextField[platform=ios]": {
	hintTextColor: 'gray'
}

in app.tss Crashes the app in IOS when some of the TextField's do not have hintText.

Hi! I tried to reproduce but got error in general when setting it to grey. However, it worked fine when setting it to #666. Can you confirm this?
Thomas Neerup 2019-10-31

No ... The problem is not the color but the fact that I'm setting the hintTextColor on all TextField's and some off them do not have a hintText

Hello [~thomas.neerup@eg.dk], So, the hintTextColor was workin for you when setting as hexadecimal color code? If so, I believe there is no issue here. Thanks.

[~thomas.neerup@eg.dk] What I meant with that, I got the same issue as you, but when setting it globally using a hex color it didn't cause any issues on my side. Can you try setting a hex color like #666 instead of gray

Rene Pot Below code stille causes my app to crash with "NSConcreteAttributedString initWithString:: nil value"; "TextField[platform=ios]" : { color: '#000000', hintTextColor: '#808080' }

Hi [~thomas.neerup@eg.dk], I have this below and I don't have a crash. I use 8.2.1.GA SDK and iOS 13.1 simulator.

   ".tf": {
   	backgroundColor: "#bbb",
   	height: 50,
   	width: 300,
   	top: 10
   }
   
   ".hint": {
   	hintText: "Fill me in"
   }
   
   "TextField": {
   	hintTextColor: "#080808"
   }

   		<TextField class="tf" ></TextField>
   		<TextField class="tf" ></TextField>
   		<TextField class="tf hint" ></TextField>
   		<TextField class="tf hint" ></TextField>
   		<TextField class="tf hint" ></TextField>

I'm sorry. It looks like it was a combination of hintTextColor: '#80808' and a hintText = null (set in code, a simple null check fixed it) Guess this bug could be closed.. But I still think it is a bug that hintTextColor: 'gray' crashes the app :)
