实现这样的圆角效果

image.png

问题： leftview和rightView因为切圆角的原因 显示不全。光标也会显示不全。

解决办法 自定义UITextField 继承UITextField

光标显示不全添加leftView

 UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15 , 30 )];
  self.leftView = view1;
  self.leftViewMode = UITextFieldViewModeAlways;

leftview和rightview 向左边或者右边偏移

 -(CGRect)rightViewRectForBounds:(CGRect)bounds{
    CGRect iconRect = [super rightViewRectForBounds:bounds];
    iconRect.origin.x -= 15;
    return iconRect;
}

- (CGRect)leftViewRectForBounds:(CGRect)bounds{
    CGRect iconRect = [super leftViewRectForBounds:bounds];
    iconRect.origin.x += 15;
    return iconRect;
}
