If you're targeting iOS 7+, this has been made much easier. Simply change the <code>tintColor</code> of the field with a cursor using the appearance proxy and it will apply throughout the app:

Swift 3.0:

<pre><code>UITextField.appearance().tintColor = .black 
</code></pre>

Objective-C:

<pre><code>[[UITextField appearance] setTintColor:[UIColor blackColor]];
</code></pre>

Same answer applies for an individual <code>UITextField</code>:

Swift 3.0:

<pre><code>myTextField.tintColor = .black 
</code></pre>

Objective-C

<pre><code>[myTextField setTintColor:[UIColor blackColor]];
</code></pre>

blocks|key|516590|text|为UITextField和UITextView设置tintColor的工作方式不同。对于UITextField，您不需要在更新tintColor之后调用额外的代码来更改光标颜色，但是对于UITextView，您需要调用额外的代码。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|516591|因此，在为UITextView设置了tintColor之后(无论是在IB中还是在代码中)，您需要调用textView.tintColorDidChange()才能应用它(实际上，它会将文本视图的配置向下传递给它的子视图层次结构)。|516592|entityMap^0|1|B|D|A|P|9|18|B|1R|9|2L|A|0|5|A|I|9|1E|T|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@$9|X|A|Y|B|C]|$9|Z|A|10|B|C]|$9|11|A|12|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|I|$]]

Setting <code>tintColor</code> for <code>UITextField</code> and <code>UITextView</code> works differently.
While for <code>UITextField</code> you don't need to call additional code after updating <code>tintColor</code> to change cursor color, but for <code>UITextView</code> you need.

So after setting <code>tintColor</code> for <code>UITextView</code> (it doesn't matter in IB or in code) you need to call <code>textView.tintColorDidChange()</code> in order to apply it (actually it will pass text view's config down to its subviews hierarchy).

This worked for me in swift:

You can also set this in storyboard: <a href="https://stackoverflow.com/a/18759577/3075340">https://stackoverflow.com/a/18759577/3075340</a>

A more general approach would be to set the UIView's appearance's tintColor.

<pre><code>UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];
</code></pre>

Makes sense if you're using many default UI elements.

I think If you want some custom colors you can go to <code>Assets.xcassets</code> folder, right click and select <code>New Color Set</code>, once you created you color you set, give it a name to reuse it. 

And you can use it just like this : 

<pre><code>import UIKit 

class ViewController: UIViewController {
 override func viewDidLoad() {
 super.viewDidLoad()
 UITextField.appearance().tintColor = UIColor(named: "YOUR-COLOR-NAME") #here
 }
}
</code></pre>

blocks|key|516219|text|杜尔盖什的方法确实有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|516220|我也多次使用这样的KVC解决方案。尽管它看起来没有文档，但它是有效的。坦率地说，您在这里没有使用任何私有方法-只有合法的键值编码。|516221|附注:昨天我的新应用程序在AppStore上出现了，这种方法没有任何问题。当我使用KVC更改一些只读属性(如navigatonBar)或私有ivars时，这并不是第一种情况。|516222|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Durgesh's approach does work.

I also used such KVC solutions many times.
Despite it seems to be undocumented, but it works. Frankly, you don't use any
private methods here - only Key-Value Coding which is legal.

P.S. Yesterday my new app appeared at AppStore without any problems with this approach. And it is not the first case when I use KVC in changing some read-only properties (like navigatonBar) or private ivars.

I'm wondering about changing the color of the cursor / caret in a <code>UITextField</code> (And <code>UITextView</code> if its the same answer) in iOS. I've seen answers for OSX development, but nothing for iOS.

Is this even possible?

Change UITextField and UITextView Cursor / Caret Color

我想知道如何在UITextField中更改光标/插入符号的颜色(如果答案相同，还可以更改UITextView )。我已经看到了OSX开发的答案，但没有关于iOS的答案。这有可能吗？
