UITextField autocapitalizationType UITextAutocapitalizationTypeAllCharacters不在设备上工作 [英] UITextField autocapitalizationType UITextAutocapitalizationTypeAllCharacters not working on device

问题描述

您可以设置UITextField的autocapitalizationType属性，以便所有输入都是大写的。我发现在模拟器上工作正常（实际上是在点击模拟器的键盘，而不是Mac的键盘），而不是在设备上？一切都保持小写。

You can set the autocapitalizationType property of a UITextField so all input is in upper case. I find that does work fine on the simulator (when actually tapping the simulator's keypad, not the Mac's keyboard), but not on the device? Everything stays lowercase.

在UICatalog演示中，我添加了textFieldNormal方法：

In the UICatalog demo I added to the textFieldNormal method:

textFieldNormal.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters;

也添加了一个委托，以显示UITextField的实际autocapitalizationType：

Added a delegate too, to display the actual autocapitalizationType for the UITextField:

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    NSLog( @"textField.autocapitalizationType=%d", textField.autocapitalizationType );
}

它将正确显示3（= UITextAutocapitalizationTypeAllCharacters），但您点击的任何内容仍为小写。我缺少什么？

It will properly display 3 (=UITextAutocapitalizationTypeAllCharacters), but anything you tap remains lowercase. What am I missing?

推荐答案

显然这是设备常规设置问题：设置 - >常规 - >键盘 - >自动 - 大写必须为ON才能将textField.autocapitalizationType设置为全部大写，否则显然会忽略设置属性。如果我打开它，一切都按预期工作。

Apparently this is a device general settings issue: Settings -> General -> Keyboard -> Auto-Capitalization must be ON to honour the setting of textField.autocapitalizationType to all upper case, else setting the property is ignored, apparently. If I switch it on everything works as expected.
