You can't set padding. Instead have a <code>UIView</code> which has your background image and the <code>UITextField</code> inside of it. Set the <code>UITextField</code> width as <code>UIViewWidth-(paddingSize x 2)</code> and the height similarly and then set it at point <code>paddingSize,paddingSize</code>.

I found a neat little hack to set the left padding for this exact situation. 

Basically, you set the leftView property of the <code>UITextField</code> to be an empty view of the size of the padding you want:

<pre><code>UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)];
textField.leftView = paddingView;
textField.leftViewMode = UITextFieldViewModeAlways;
</code></pre>

Worked like a charm for me!

In Swift 3/ Swift 4, it can be done by doing that

<pre><code>let paddingView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 5, height: 20))
textField.leftView = paddingView
textField.leftViewMode = .always
</code></pre>

I created this category implementation and added it to the top of the <code>.m</code> file. 

<pre><code>@implementation UITextField (custom)
 - (CGRect)textRectForBounds:(CGRect)bounds {
 return CGRectMake(bounds.origin.x + 10, bounds.origin.y + 8,
 bounds.size.width - 20, bounds.size.height - 16);
 }
 - (CGRect)editingRectForBounds:(CGRect)bounds {
 return [self textRectForBounds:bounds];
 }
@end
</code></pre>

Based off the link Piotr Blasiak provided. It seemed simpler then creating a whole new subclass, and also simpler then adding the additional <code>UIView</code>. Still, it seems like something is missing to not be able to control the padding inside a text field.

Swift 4 solution: 

<pre class="lang-swift prettyprint-override"><code>class CustomTextField: UITextField {
 struct Constants {
 static let sidePadding: CGFloat = 10
 static let topPadding: CGFloat = 8
 }

 override func textRect(forBounds bounds: CGRect) -&gt; CGRect {
 return CGRect(
 x: bounds.origin.x + Constants.sidePadding,
 y: bounds.origin.y + Constants.topPadding,
 width: bounds.size.width - Constants.sidePadding * 2,
 height: bounds.size.height - Constants.topPadding * 2
 )
 }

 override func editingRect(forBounds bounds: CGRect) -&gt; CGRect {
 return self.textRect(forBounds: bounds)
 }
}

^ these suggestions are great for those who are programmatically creating an interface. 

But there are two LAZY EASY WAYS for those of us who use the Xcode interface builder:

<ul>
<li>easier: put a UIImageView behind a text field</li>
<li>easiest: change the border style on your to the simple black square (second from left option), then add your image as a background image. The image takes precedence over the square, so you still get the padding needed for a normal image background, without the square actually being drawn on.</li>
</ul>

EDIT: you can also use the black sphere (third from left option when selecting the UITextBox in IB), it does not work with the far right, "graphical sphere" style.

A good approach to add padding to UITextField is to subclass and add an edgeInsets property. You then set the edgeInsets and the UITextField will be drawn accordingly. This will also function correctly with a custom leftView or rightView set.

OSTextField.h

<pre><code>#import &lt;UIKit/UIKit.h&gt;

@interface OSTextField : UITextField

@property (nonatomic, assign) UIEdgeInsets edgeInsets;

@end
</code></pre>

OSTextField.m

<pre><code>#import "OSTextField.h"

@implementation OSTextField

- (id)initWithFrame:(CGRect)frame{
 self = [super initWithFrame:frame];
 if (self) {
 self.edgeInsets = UIEdgeInsetsZero;
 }
 return self;
}

-(id)initWithCoder:(NSCoder *)aDecoder{
 self = [super initWithCoder:aDecoder];
 if(self){
 self.edgeInsets = UIEdgeInsetsZero;
 }
 return self;
}

- (CGRect)textRectForBounds:(CGRect)bounds {
 return [super textRectForBounds:UIEdgeInsetsInsetRect(bounds, self.edgeInsets)];
}

- (CGRect)editingRectForBounds:(CGRect)bounds {
 return [super editingRectForBounds:UIEdgeInsetsInsetRect(bounds, self.edgeInsets)];

@Evil trout's answer is great. I have been using this approach for quite a some time now. The only thing it lacks is "dealing with numerous text fields". I tried other approaches but does not seem to work.

Subclassing UITextField just to add a padding didn't make any sense to me. So, I iterated over all UITextFields to add the padding.

<pre><code>-(void) addPaddingToAllTextFields:(UIView*)view {

 for(id currentView in [view subviews]){
 if([currentView isKindOfClass:[UITextField class]]) {
 // Change value of CGRectMake to fit ur need
 [currentView setLeftView:[[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 20)]];
 [currentView setLeftViewMode:UITextFieldViewModeAlways];
 }

 if([currentView respondsToSelector:@selector(subviews)]){
 [textfieldarray addObjectsFromArray:[self addPaddingToAllTextFields:currentView]];

<h1>Set padding for UITextField with UITextBorderStyleNone: Swift</h1>
Based on @Evil Trout's most voted answer I created a custom method in my ViewController class, like shown bellow:
<pre><code>- (void) modifyTextField:(UITextField *)textField
{
 UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)];
 textField.leftView = paddingView;
 textField.leftViewMode = UITextFieldViewModeAlways;
 textField.rightView = paddingView;
 textField.rightViewMode = UITextFieldViewModeAlways;

 [textField setBackgroundColor:[UIColor whiteColor]];
 [textField setTextColor:[UIColor blackColor]];
}
</code></pre>
Now I can call that method inside (viewDidLoad method) and send any of my TextFields to that method and add padding for both right and left, and give text and background colors by writing just one line of code, as follows:
<pre><code>[self modifyTextField:self.firstNameTxtFld];
</code></pre>
This Worked perfectly on iOS 7!
I know that adding too much Views might make this a bit heavier class to be loaded. But when concerned about the difficulty in other solutions, I found myself more biased to this method and more flexible with using this way. ;)
Thanks for the Hack &quot;Evil Trout&quot;! (bow)
I thought I should update this answer's code snippet with Swift:
Since Swift allow us to write extensions for the existing classes, let's write it in that way.
<pre><code>extension UITextField {
 func addPaddingToTextField() {
 let paddingView: UIView = UIView.init(frame: CGRectMake(0, 0, 8, 20))
 self.leftView = paddingView;
 self.leftViewMode = .Always;
 self.rightView = paddingView;
 self.rightViewMode = .Always;

 
 self.backgroundColor = UIColor.whiteColor()
 self.textColor = UIColor.blackColor()
 }
}
</code></pre>
Usage:
<pre><code>self.firstNameTxtFld.addPaddingToTextField()
</code></pre>
Hope this would be helpful to somebody else out there! 
Cheers!

Edit: Still works in iOS 11.3.1

In iOS 6 <code>myTextField.leftView = paddingView;</code> is causing issue

This solves the problem

<pre><code>myTextField.layer.sublayerTransform = CATransform3DMakeTranslation(5, 0, 0)
</code></pre>

For right aligned text field use <code>CATransform3DMakeTranslation(-5, 0, 0)</code> as mention by latenitecoder in comments

 override func editingRectForBounds(bounds: CGRect) -&gt; CGRect {

The best way to do this is simply make a class using subclass of UITextField and in .m file

<pre><code> #import "CustomTextField.h"
 #import &lt;QuartzCore/QuartzCore.h&gt;
 @implementation CustomTextField


- (id)initWithCoder:(NSCoder*)coder 
 {
 self = [super initWithCoder:coder];

 if (self) {

//self.clipsToBounds = YES;
//[self setRightViewMode:UITextFieldViewModeUnlessEditing];

self.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0,15,46)];
self.leftViewMode=UITextFieldViewModeAlways;
 }

 return self;

 }
</code></pre>

by doing this go to your storyboard or xib and click on identity inspector and replace UITextfield with your own "CustomTextField" in class option.

Note: If you simply give padding with auto layout for textfield then your application will not run and show only blank screen.

<a href="https://stackoverflow.com/a/6416234/4407087">Nate Flink's</a> answer is my favourite, but don't forget about right/left views.
E.g for <code>UITextField</code> subclass:

<pre><code>override func rightViewRectForBounds(bounds: CGRect) -&gt; CGRect {
 let rightViewBounds = super.rightViewRectForBounds(bounds)

 return CGRectMake(CGRectGetMinX(rightViewBounds) - 10, CGRectGetMinY(rightViewBounds), CGRectGetWidth(rightViewBounds), CGRectGetHeight(rightViewBounds))
}
</code></pre>

Above code set right padding for <code>rightView</code> of <code>UITextField</code>.

If anyone is looking for <code>Swift 4.0</code> version then below <code>extension</code> is work. It has both <code>Left</code> and <code>Right</code> padding for <code>UITextField</code>. Actually it is <code>IBInspectable</code> for storyboard configuration. You can set the value directly from the Interface Builder / Storyboard. This is tested code in Swift 4.0 version and Xcode 9.0

Keep in mind that if you want to enable <code>Clear Button</code> on the same <code>UITextField</code> then your have to keep Right Padding blank.

<pre><code>import UIKit

extension UITextField {

 @IBInspectable var paddingLeft: CGFloat {
 get {
 return leftView!.frame.size.width
 }
 set {
 let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
 leftView = paddingView
 leftViewMode = .always
 }
 }

 @IBInspectable var paddingRight: CGFloat {
 get {
 return rightView!.frame.size.width
 }
 set {
 let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
 rightView = paddingView
 rightViewMode = .always 
 }
 }
} 
</code></pre>

I wanted to use a custom background for my <code>UITextFields</code>. This works fine except for the fact that I have to use <code>UITextBorderStyleNone</code> to make it look pretty. This forces the text to stick to the left without any padding.

Can I set a padding manually so that it looks similar to <code>UITextBorderStyleRoundedRect</code> except for using my custom background image?
