Add a target for your desired event programatically, or, use IB.

<pre><code>UITextField * touchyTextField = [[UITextField alloc] initWithFrame:CGRectMake(0.0, 0.0, 200.0, 21.0)];

[touchyTextField addTarget:self 
 action:@selector(yourDesiredMethod)

blocks|key|1954225|text|一种大概的方法是创建一个填充设置为clear以覆盖所有空间的UIButton，并在其上面创建一个UITextField。如果用户在文本字段中触摸，文本字段应发送事件，如果用户在文本字段之外触摸，则UIButton将发送事件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1954226|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Well a round about way of doing it would be to create a UIButton with the fill set to clear to cover all of the space, and a UITextField on top of it. If the user touches in the text field, the text field should send an event, and if the user touches outside of the text field, the UIButton will send the event.

Good answer here:
<a href="https://stackoverflow.com/questions/4702617/change-default-touch-events-for-uitextfield?rq=1">Change default touch events for UITextField</a>

Use the text field's delegate and do what you want to do in textFieldShouldBeginEditing:

You can return NO to prevent the default behavior.

I have faced this problem just today. My goal was to change textfield's background color on touch down and revert it back on touch up/cancel.
It is weird that touch down is sent to target from UITextField, but touch up inside, touch up outside and even touch cancel are not.
I found the solution. It is simple. Just create a subclass of UITextField and override touchesEnded: and touchesCancelled:.

<pre><code>@interface TextField : UITextField

@end

@implementation CuteTextField

- (id)initWithFrame:(CGRect)frame
{
 self = [super initWithFrame:frame];
 if (self) {
 // Initialization code
 }
 return self;
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
 [super touchesEnded:touches withEvent:event];
 self.backgroundColor=GetDefaultBackgroundColor();
}

-(void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{
 [super touchesCancelled:touches withEvent:event];
 self.backgroundColor=GetDefaultBackgroundColor();
}

@end
</code></pre>

blocks|key|1741012|text|您可以为UiView创建类别并覆盖touchesBegan方法，如下所示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1741013|它对于me.And工作得很好，它是这个问题的集中式解决方案。|1741014|#import+"UIView%2BKeyboard.h"

You can create category for the UiView and override the touchesBegan meathod as follows.

It is working fine for me.And it is centralize solution for this problem. 

<pre><code>#import "UIView+Keyboard.h"
@implementation UIView(Keyboard)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
 [self.window endEditing:true];
 [super touchesBegan:touches withEvent:event];
}

I want to respond to touch events (specifically <code>UIControlEventTouchUpInside</code> and <code>UIControlEventTouchUpOutside</code>) on a <code>UITextField</code>, but the only event that comes through is <code>UIControlEventTouchCancel</code>.

I can't use <code>UIControlEventEditingDidBegin</code>, because it only occurs when field gains focus, which is not what I'm trying to detect. I want to know when the user lifts their finger, and whether it was inside or outside the text field, regardless of current focus state.

Does anyone know a way to accomplish this?

To be clear I've tried using <code>addTarget:action:forControlEvents</code> and it does not work. The touch up event is prevented by the cancel. I want a way to detect the touch up before the <code>UITextField</code> consumes it and produces the Cancel event.

Also, I'd like to avoid creating any extra views if possible.

How can I respond to touch events on a UITextField?

我想在UITextField上响应触摸事件(特别是UIControlEventTouchUpInside和UIControlEventTouchUpOutside)，但唯一通过的事件是UIControlEventTouchCancel。我不能使用UIControlEventEditingDidBegin，因为它只在字段...
