UITextField border color

Import QuartzCore framework in you class:

#import <QuartzCore/QuartzCore.h>

and for changing the border color use the following code snippet (I'm setting it to redColor),

    textField.layer.cornerRadius=8.0f;    textField.layer.masksToBounds=YES;    textField.layer.borderColor=[[UIColor redColor]CGColor];    textField.layer.borderWidth= 1.0f;

For reverting back to the original layout just set border color to clear color,

    serverField.layer.borderColor=[[UIColor clearColor]CGColor];

in swift code

    textField.layer.borderWidth = 1    textField.layer.borderColor = UIColor.whiteColor().CGColor

Try this:

UITextField *theTextFiels=[[UITextField alloc]initWithFrame:CGRectMake(40, 40, 150, 30)];    theTextFiels.borderStyle=UITextBorderStyleNone;    theTextFiels.layer.cornerRadius=8.0f;    theTextFiels.layer.masksToBounds=YES;        theTextFiels.backgroundColor=[UIColor redColor];    theTextFiels.layer.borderColor=[[UIColor blackColor]CGColor];    theTextFiels.layer.borderWidth= 1.0f;    [self.view addSubview:theTextFiels];    [theTextFiels release];

and import QuartzCore:

#import <QuartzCore/QuartzCore.h>

Import the following class:

#import <QuartzCore/QuartzCore.h> 

//Code for setting the grey color for the border of the text field

[[textField layer] setBorderColor:[[UIColor colorWithRed:171.0/255.0                                                   green:171.0/255.0                                                    blue:171.0/255.0                                                   alpha:1.0] CGColor]];

Replace 171.0 with the respective color number as required.
