很简单很常用的一些东西，希望给需要的人帮助。
效果图如下：
自定义textField
init() {
super.init(frame: CGRect(x: , y: , width: yourWidth, height: yourHeight))
//光标颜色修改
self.tintColor = UIColor.orangeColor()
}
override func editingRectForBounds(bounds: CGRect) -> CGRect {
return CGRectInset(bounds, , );
}
override func textRectForBounds(bounds: CGRect) -> CGRect {
return CGRectInset(bounds, , )
}
override func placeholderRectForBounds(bounds: CGRect) -> CGRect {
return CGRectInset(bounds, , )
}
override func leftViewRectForBounds(bounds: CGRect) -> CGRect {
var iconRect = super.leftViewRectForBounds(bounds)
iconRect.origin.x = iconRect.origin.x +
return iconRect
}
然后在需要使用的controller调用即可
//其他非相关代码已省略
func setupMobelLoginUI(){
...
mobTxtFld.backgroundColor = LoginConst.tfBackgroundColor
mobTxtFld.layer.cornerRadius = LoginConst.commonHeight /
mobTxtFld.clipsToBounds = true
mobTxtFld.layer.borderColor = LoginConst.tfBorderColor.CGColor
mobTxtFld.layer.borderWidth =
//leftView相关设置
let mobIcon = UIImageView(image: UIImage(named: "login_mobile"))
mobTxtFld.leftViewMode = UITextFieldViewMode.Always
mobTxtFld.leftView = mobIcon
view.addSubview(mobTxtFld)
mobTxtFld.snp_makeConstraints { (make) in
make.top.equalTo(titleLb.snp_bottom).offset(LoginConst.topVOffset)
make.centerX.equalTo(self.view)
make.width.equalTo()
make.height.equalTo(LoginConst.commonHeight)
}
//leftView相关设置
let codeIcon = UIImageView(image: UIImage(named: "login_yanzheng"))
verifyCodeTxtFld.leftViewMode = UITextFieldViewMode.Always
verifyCodeTxtFld.leftView = codeIcon
verifyCodeTxtFld.backgroundColor = LoginConst.tfBackgroundColor
verifyCodeTxtFld.layer.cornerRadius = LoginConst.commonHeight /
verifyCodeTxtFld.layer.masksToBounds = true
verifyCodeTxtFld.layer.borderColor = LoginConst.tfBorderColor.CGColor
verifyCodeTxtFld.layer.borderWidth =
view.addSubview(verifyCodeTxtFld)
verifyCodeTxtFld.snp_makeConstraints { (make) in
make.top.equalTo(mobTxtFld.snp_bottom).offset(LoginConst.verifyVMargin)
make.width.height.centerX.equalTo(mobTxtFld)
}
...
}
