XCode : How to Add Left and Right Padding on Text Field? - ios

Question

I have this .h code :
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
#property (strong, nonatomic) IBOutlet UITextField *fieldEmail;
#property (strong, nonatomic) IBOutlet UITextField *fieldPassword;
#property (strong, nonatomic) IBOutlet UILabel *titleLogin;
- (IBAction)buttonRegister;
- (IBAction)buttonLogin;
- (IBAction)loginFacebook;
- (IBAction)loginTwitter;
#end
and this is my .m code :
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[_fieldEmail setFont:[UIFont fontWithName:#"ABeeZee-Regular" size:14]];
[_titleLogin setFont:[UIFont fontWithName:#"Raleway-ExtraLight" size:28]];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)buttonRegister {
}
- (IBAction)buttonLogin {
}
- (IBAction)loginFacebook {
}
- (IBAction)loginTwitter {
}
#end
now, what I want to do is to add padding on left and right of these 2 text fields : fieldEmail and fieldPassword so it has some space because I put an image as background on both text fields.
I tried to add this code on my .m file under - (void)viewDidLoad :
UIView *fieldEmail = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
[UITextField setLeftViewMode:UITextFieldViewModeAlways];
[UITextField setLeftView:fieldEmail];
but my XCode gave me this error message :
no known class method for selector 'setLeftViewMode'
no known class method for selector 'setLeftView'
by the way, I'm using XCode 4.6.3. does this version have special code to add padding on text field? thank you.

Answer 1

leftViewMode and leftView are properties of UITextField, not class methods. You need to assign them to instances.
yourTextField.leftViewMode = UITextFieldViewModeAlways;
yourTextField.leftView = fieldEmail;
