UITextfield leftView/rightView padding on iOS7

The leftView and rightView views of an UITextField on iOS7 are really close to the textfield border.

How may I add some (horizontal) padding to those items?

I tried modifying the frame, but did not work

uint padding = 10;//padding for iOS7
UIImageView * iconImageView = [[UIImageView alloc] initWithImage:iconImage];
iconImageView.frame = CGRectMake(0 + padding, 0, 16, 16);
textField.leftView = iconImageView;

Please, note that I'm not interested in adding padding to the textfield's text, like this Set padding for UITextField with UITextBorderStyleNone

Was just working on this myself and used this solution:

- (CGRect) rightViewRectForBounds:(CGRect)bounds {

    CGRect textRect = [super rightViewRectForBounds:bounds];
    textRect.origin.x -= 10;
    return textRect;

This will move the image over from the right by 10 instead of having the image squeezed up against the edge in iOS 7.

Additionally, this was in a subclass of UITextField, which can be created by:

  1. Create a new file that's a subclass of UITextField instead of the default NSObject
  2. Add a new method named - (id)initWithCoder:(NSCoder*)coder to set the image

    - (id)initWithCoder:(NSCoder*)coder {
        self = [super initWithCoder:coder];
        if (self) {
            self.clipsToBounds = YES;
            [self setRightViewMode:UITextFieldViewModeUnlessEditing];
            self.leftView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"textfield_edit_icon.png"]];
        return self;
  3. You may have to import #import <QuartzCore/QuartzCore.h>

  4. Add the rightViewRectForBounds method above

  5. In Interface Builder, click on the TextField you would like to subclass and change the class attribute to the name of this new subclass
