Change UITextField and UITextView Cursor / Caret Color
提问by RileyE
I'm wondering about changing the color of the cursor / caret in a UITextField(And UITextViewif its the same answer) in iOS. I've seen answers for OSX development, but nothing for iOS.
我想知道如何在 iOS 中更改 a UITextField（UITextView如果答案相同）中光标/插入符号的颜色。我已经看到了 OSX 开发的答案，但没有看到 iOS 的答案。
Is this even possible?

If you're targeting iOS 7+, this has been made much easier. Simply change the tintColorof the field with a cursor using the appearance proxy and it will apply throughout the app:
如果您的目标是 iOS 7+，这将变得更加容易。只需tintColor使用外观代理使用光标更改字段的 ，它将在整个应用程序中应用：
Swift 3.0:
斯威夫特 3.0：
UITextField.appearance().tintColor = .black
Objective-C:
目标-C：
[[UITextField appearance] setTintColor:[UIColor blackColor]];
Same answer applies for an individual UITextField:
同样的答案适用于个人UITextField：
Swift 3.0:
斯威夫特 3.0：
myTextField.tintColor = .black
Objective-C
目标-C
[myTextField setTintColor:[UIColor blackColor]];

Note: This answer is out of date and should be used for pre-iOS 7 development only. See other answers for a 1 line solution using the appearance proxy in iOS 7.
注意：此答案已过时，应仅用于 iOS 7 之前的开发。请参阅使用 iOS 7 中的外观代理的 1 行解决方案的其他答案。
I arrived at this question after I faced the same problem in a project I was working on.
在我正在从事的项目中遇到同样的问题后，我想到了这个问题。
I managed to create a solution that will be accepted by the AppStore review team as it does not use any existing Private APIs.
我设法创建了一个将被 AppStore 审核团队接受的解决方案，因为它不使用任何现有的私有 API。
I have created a control called DGTextField that extends UITextField.
我创建了一个名为 DGTextField 的控件，它扩展了 UITextField。

yourTextField.tintColor = [UIColor whiteColor];
It works if you set it in code, 'cos somehow color trigger doesn't do it in the Interface Builder(Xcode 6.1.1). It suited well without a need to change any appearance proxy.
如果您在代码中设置它，它就可以工作，'因为颜色触发器在界面生成器（Xcode 6.1.1）中不会这样做。它非常适合，无需更改任何外观代理。

Setting tintColorfor UITextFieldand UITextViewworks differently.
While for UITextFieldyou don't need to call additional code after updating tintColorto change cursor color, but for UITextViewyou need.
设置tintColor为UITextField和UITextView工作方式不同。虽然UITextField您不需要在更新后调用额外的代码tintColor来更改光标颜色，但UITextView您需要。
So after setting tintColorfor UITextView(it doesn't matter in IB or in code) you need to call textView.tintColorDidChange()in order to apply it (actually it will pass text view's config down to its subviews hierarchy).
因此，设置后tintColor的UITextView（这并不重要IB或代码），你需要调用textView.tintColorDidChange()，以应用它（实际上它会通过文本视图的配置到其子视图层次）。

This worked for me in swift:
这很快对我有用：
UITextField.tintColor = UIColor.blackColor()
You can also set this in storyboard: https://stackoverflow.com/a/18759577/3075340
您也可以在情节提要中进行设置：https: //stackoverflow.com/a/18759577/3075340

A more general approach would be to set the UIView's appearance's tintColor.
更通用的方法是设置 UIView 外观的 tintColor。
UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];
Makes sense if you're using many default UI elements.
如果您使用许多默认 UI 元素，这很有意义。

Try, Its working for me.
试试吧，它对我有用。
[[self.textField valueForKey:@"textInputTraits"] setValue:[UIColor redColor] strong textforKey:@"insertionPointColor"];

It is only possible by accessing a private property and therefore may cause an Apple AppStore app rejection.
只有通过访问私有财产才有可能，因此可能会导致 Apple AppStore 应用程序拒绝。
