Ios 将属性标签设置为导航标题,ios,uinavigationcontroller,uilabel,Ios,Uinavigationcontroller,Uilabel,我正在使用swift 4开发IOS。我必须使导航控制器，与中心对齐的应用程序标题与图像在其左侧。但我不知道如何将图像附加到其左侧。属性图像始终位于其右侧 为此，我将附加字符串两次。下面是代码 //Get image and set it's size let image = UIImage(named: "user2") let newSize = CGSize(width: 30, height: 30) //Resize image UIGraphic

我正在使用swift 4开发IOS。我必须使导航控制器，与中心对齐的应用程序标题与图像在其左侧。但我不知道如何将图像附加到其左侧。属性图像始终位于其右侧

为此，我将附加字符串两次。下面是代码

   //Get image and set it's size
    let image = UIImage(named: "user2")
    let newSize = CGSize(width: 30, height: 30)

    //Resize image
    UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
    image?.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
    let imageResized = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    //Create attachment text with image
    let attachment = NSTextAttachment()
    attachment.image = imageResized
    let attachmentString = NSAttributedString(attachment: attachment)
    let myString = NSMutableAttributedString(string: "")
    myString.append(attachmentString)
    let strAttachment = NSAttributedString(string: "My Ios App" )
    myString.append(strAttachment)

    navLabel.attributedText = myString

    self.navigationItem.titleView = navLabel
我得到的是一些类似下图的东西在左边

我想要什么：

        let navgationView = UIView()

        let label = UILabel()
        label.text = " My Ios App"
        label.sizeToFit()
        label.center = navgationView.center
        label.textAlignment = NSTextAlignment.center

        let image = UIImageView()
        image.image = UIImage(named: "user")
        let imageAspect = image.image!.size.width/image.image!.size.height
        image.frame = CGRect(x: label.frame.origin.x-label.frame.size.height*imageAspect, y: label.frame.origin.y, width: label.frame.size.height*imageAspect, height: label.frame.size.height)
        image.contentMode = UIViewContentMode.scaleAspectFit

        navgationView.addSubview(label)
        navgationView.addSubview(image)

        self.navigationItem.titleView = navgationView
        navgationView.sizeToFit()
我只希望图像显示的文本和图像之间的空间。
我希望图像是好看的。文本应垂直于图像中心。实现这一目标的好方法是什么

如果要调整附件位置，必须使用
attachment.bounds
属性，如果要调整文本垂直对齐方式，则需要使用
nsattributestring
基线偏移
键

我想调整文本和图像之间的空间，文本应该垂直居中。请给我看代码，但你在文本中使用空格给了空格。有没有其他办法给空间？另外，请告诉我图像首选大小。通过使用负值@Androidteem更改附件边界x，可以达到相同的效果。在文本中添加空格很容易。我想调整文本和图像之间的空格，并且文本应垂直居中。请给我看代码，但你在文本中使用空格给了空格。有没有其他办法给空间？另外，请告诉我图像的首选大小您可以通过将附件边界x更改为负值来实现相同的效果@Androidteem，在文本中添加空格很容易没有水平空格，但是设置图像与文本高度相等的想法很好没有水平空格，然而，将图像设置为文本高度相等的想法是好的
