if all of your text fields are inside the same view controller, simply add inside the view controller's implementation:

for (UITextField *textField in self.view.subviews) {
if ([textField isKindOfClass:[UITextField class]]) {
  textField.backgroundColor = [UIColor exampleColor];
 }
}

if they are not in the same view controller, add all of the view controller into an array and do it from there:

NSArray *array = @[emailField, nameField, etc...]
    for (UITextField *textField in array)
textField.backgroundColor = [UIColor exampleColor];
}

You can set background color in storyboard. as you created those in storyboard which is good practice. But if you created those textfield programatically then it would be good practice to set BG color programatically by a for loop.

You could do it purely in code like this:

NSArray *textFields = @[self.emailTextField, self.nameTextField, self.firstNameTextField ... etc];
for (UITextField *textField in textFields) {
    textField.backgroundColor = [UIColor redColor];
}

Alternatively you can create an IBOutletCollection in your storyboard and hook it up all text fields to a single property on your view controller:

@interface MyViewController : UIViewController

@property (nonatomic, strong) IBOutletCollection(UITextField) NSArray *textFields;

@end

Then iterate of self.textFields in a similar manner to my first example.
