set color inside textfield near border

Question

I want to change textfield color not background color but near part of textfield border just like shadow. As shown in image.

Answer 1

如果你想在图像中显示时在UITextField添加阴影，那么最简单的方法就是该UITextField设计图像并将其设置为UITextField背景。

Answer 2

IT's so simple just slice that image and put that image in Textfield background. or Use the Code suggest by @Mrug.

textField.layer.cornerRadius=5.0f; 
textField.layer.masksToBounds=YES; 
textField.layer.borderColor=[[UIColor blackColor]CGColor];
textField.layer.borderWidth= 1.5f;
