我要怒答此题! (刚刚学的新知识终于有机会装逼了)

在 Xcode 6 里面新引入俩个关键字来更友好的使用 Storyboard，分别是

1. @IBInspectable: 被这个关键字所修饰的属性，可以在 IB 的属性页里面进行设置

2. @IBDesignable: 可以让你的 UIView 及其子类, 代码里面的操作的视图的结果显示到 Storyboard 对应的 View 上

意思就是说我们可以使用这俩个关键字来达到题主所需要的效果, 如图:

该 HJTextFeild 代码如下:

@IBDesignable class HJTextFeild: UITextField {
    
    @IBInspectable var leftImage: UIImage? {
        set {
            let leftImgView = UIImageView(image: newValue)
            leftImgView.contentMode = .ScaleAspectFit
            leftImgView.frame = CGRect(x: frame.height*0.1,
                                       y: frame.height*0.1,
                                       width: frame.height*0.8,
                                       height: frame.height*0.8)
            leftView = leftImgView
            leftViewMode = .Always
        }
        
        get {
            if let leftImgView = leftView as? UIImageView {
                return leftImgView.image
            }
            return nil
        }
    }
}

你可能要用代码解决：

UITextField *textField = [[UITextField alloc] init];
[textField setLeftViewMode:UITextFieldViewModeAlways];
[textField setLeftView:<#your-icon-image-view#>];

自带属性leftView和rightView

- (void)configureUserText:(rewriteFiled *)text {
    text.clearButtonMode = UITextFieldViewModeWhileEditing;
    text.adjustsFontSizeToFitWidth = YES;
    text.returnKeyType = UIReturnKeyDone;
    self.userView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 70, 30)];
    UIImageView *userMageView = [[UIImageView alloc] initWithFrame:CGRectMake(5, 4.5, 22, 22)];
    userMageView.image = [UIImage imageNamed:@"user"];
    UILabel *userName = [[UILabel alloc] initWithFrame:CGRectMake(30, 4, 40, 22)];
    userName.text = @"账号:";
    userName.font = [UIFont systemFontOfSize:15];
    [self.userView addSubview:userMageView];
    [self.userView addSubview:userName];
    text.leftView = self.userView;
    text.leftViewMode = UITextFieldViewModeAlways;
    text.delegate = self;
}
