iOS10：当secureTextEntry时，UITextfield会挂起长输入

Question

Strange behaviour from UITextfield with secureTextEntry . Platform : iOS10 Both on iPhone (Device) and Simulator. UITextfield hangs with long input which is greater than the keyboard's width, when secureTextEntry is on. The keyboard's pressed key stays popped out.

Answer 1

Yes, it is a bug.

Bug is like :

An app can freeze when a user types a large password into a textfield that tries to scale down the text to fit.

Possible solution : Disable to Fit for password/secured field.

1. change the secure password character in UITextfield
2. Secure UITextField text change to (*) asterisk character

Answer 2

Looks like this is a bug in SDK from Apple in iOS10. I have resolved it with disabling Adjust to Fit for password field, (as per:

TextEdit field input hangs on iOS10 )

Answer 3

这已经在iOS 10.2中得到了修复!!

Answer 4

There's a bug in iOS 10.0.2... https://openradar.appspot.com/28590124

I have resolved it with disabling Adjust to Fit for password field, but this is more workaround than fix.

this bug fixed in 10.2
