Add image to UITextField in Xcode?
UITextField has a rightView property, if you have image like this- 
then You can easly set ImageView object to rightView:
UITextField *myTextField = [[UITextField alloc] init];myTextField.rightViewMode = UITextFieldViewModeAlways;myTextField.rightView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"downArrow.png"]];
In Swift:
textField.leftViewMode = UITextFieldViewMode.AlwaystextField.leftView = UIImageView(image: UIImage(named: "imageName"))
You can put the UIImageView to the left of your UITextField.
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(96, 40, 130, 20)];[textField setLeftViewMode:UITextFieldViewModeAlways];textField.leftView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"searchIccon.png"]];
