You can try following for disabling only built in long press gesture

<pre><code>for (UIGestureRecognizer *recognizer in textView.gestureRecognizers) {
 if ([recognizer isKindOfClass:[UILongPressGestureRecognizer class]]){
 recognizer.enabled = NO;
 }
}
</code></pre>

or 

delegate method for all :-

<pre><code>- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
return NO;
}
</code></pre>

blocks|key|5433481|text|要做到这一点，一种很好且简洁的方法是，您可以为UITextField创建一个自定义类，并且在自定义类中，您可以覆盖导致出现放大视图的长按手势。这个自定义类可以在我们不想显示测试字段的放大视图的所有地方使用。只需使用下面的类来代替UITextField类|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5433482|class+CustomTextView:+UITextView+{

++++override+func+addGestureRecognizer(gestureRecognizer:+UIGestureRecognizer)+{
++++++++if+(gestureRecognizer.isKindOfClass(UILongPressGestureRecognizer))+{
++++++++++++gestureRecognizer.enabled+=+false;
++++++++}
++++++++super.addGestureRecognizer(gestureRecognizer)
++++++++return
++++}

One good and clean way to do this is you can create a custom class for the UITextField and in the custom class you can override the long-press gesture which is causing the magnification view appear. 
This custom class can be used in all places where we don't want to show the magnification view for test field. Just use below class in place of UITextField class

<pre><code>class CustomTextView: UITextView {

 override func addGestureRecognizer(gestureRecognizer: UIGestureRecognizer) {
 if (gestureRecognizer.isKindOfClass(UILongPressGestureRecognizer)) {
 gestureRecognizer.enabled = false;
 }
 super.addGestureRecognizer(gestureRecognizer)
 return
 }
}
</code></pre>

@Neeraj answer in Swift 4 :

<pre><code>class CustomTextView: UITextView {

 override func addGestureRecognizer(_ gestureRecognizer: UIGestureRecognizer) {

 if gestureRecognizer.isKind(of: UILongPressGestureRecognizer.self) {
 gestureRecognizer.isEnabled = false
 }
 return super.addGestureRecognizer(gestureRecognizer)
 }
}
</code></pre>

blocks|key|2280126|text|在自定义类中的这种组合是我唯一能够为自己工作的东西，在第一次长按下时，它有时仍然会使放大镜出现：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2280127|//swift+4.2

{

This combination in a custom class is the only thing I've been able to get to work for me, and on the first long press it still sometimes makes the magnifying glass appear:

<pre><code>//swift 4.2
override func addGestureRecognizer(_ gestureRecognizer: UIGestureRecognizer)
{

 if gestureRecognizer.isKind(of: UILongPressGestureRecognizer.self)
 {
 print(gestureRecognizer.name.unwrappedDebugString)
 gestureRecognizer.isEnabled = false
 }
 return super.addGestureRecognizer(gestureRecognizer)
}
override func becomeFirstResponder() -&gt; Bool
{
 for recognizer in self.gestureRecognizers ?? []
 {
 if (recognizer is UILongPressGestureRecognizer)
 {
 recognizer.isEnabled = false
 }
 }
 return super.becomeFirstResponder()
}
</code></pre>

I come across many post about disabling long press in UItextView, but that same process is not working for UITextField and UISearchBar. 

Is there any way to disable Long press on UITextField and UISearchBar so I can avoid Magnifying glass on long press?

I have already checked "<a href="https://stackoverflow.com/questions/866200/disable-magnifying-glass-in-uitextfield">Disable Magnifying Glass in UITextField</a>" but solution given there is not actually disabling magnifying glass. Its just not allowing cursory to Move between text. but still displaying Magnifying glass. 

I want to disable Long Press - to avoid <a href="https://stackoverflow.com/questions/40930220/magnifying-glass-displaying-irrelevant-content-in-uitextfield">Problem</a> which I am facing with magnifying glass. I want to disable it now. will enable it again when I will able to fix this.

How to disable Long press gesture recogniser in UITextField and UISearchBar?

我看到很多关于在UItextView中禁用长时间按的帖子，但同样的过程在UITextField和UISearchBar上是不起作用的。有没有办法在UITextField和UISearchBar上禁用长按，这样我就可以避免长按时放大镜？我已经检查了"“，但给出的解决方案实际上并没有禁用放大镜。它只是不允许粗略的在文本之间...
