我试图在UITextField中保留图像和文本之间的空格。我有这个:
self.txtUsername.leftViewMode = UITextFieldViewMode.Always
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
let image = UIImage(named: "icoUserName")
imageView.image = image
self.txtUsername.leftView = imageView
这成功添加了一张图片,但我希望它们之间的间隙更少。我怎样才能做到这一点?

尝试按左下方添加:
let envelopeView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
let image = UIImage(named: "icoUserName")
envelopeView.image = image
var viewLeft: UIView = UIView(frame: CGRectMake(20, 0, 30, 30))// set per your requirement
viewLeft.addSubview(envelopeView)
textField.leftView = viewLeft
textField.leftViewMode = UITextFieldViewModeAlways
Swift 3.0
let envelopeView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
let image = UIImage(named: "icoUserName")
envelopeView.image = image
let viewLeft: UIView = UIView(frame: CGRect(x: 20, y: 0, width: 30, height: 30))// set per your requirement
viewLeft.addSubview(envelopeView)
txtUsername.leftView = viewLeft
txtUsername.leftViewMode = UITextFieldViewMode.always
