Custom Text Field in iPhone

Introduction

In this article I will create an Empty View application. Here I will implement a text field using code. 

To understand it we use the following..

Step 1

Open XCode by double-clicking on it.

Step 2

Create a New XCode Project by clicking on it.

Step 3

Now select Empty View Application and click on Next.

Step 4

Now provide your Product Name and Company Identifier.

Step 5

Select the location where you want to save your project and click on Create.

Step 6

Now here we write the code.

AppDelegate.h

#import <UIKit/UIKit.h>
@interface testviewAppDelegate : UIResponder <UIApplicationDelegate,UITextFieldDelegate>
@property (strong, nonatomic) UIWindow *window;
@property (nonatomic, retain, readonly) UITextField *textFieldNormal;
@end

AppDelegate.m

#import "AppDelegate.h"
#define kTextFieldWidth 260.0
#define kLeftMargin 20.0
#define kTextFieldHeight 30.0
const NSInteger kViewTag = 1;
@implementation AppDelegate
@synthesize textFieldNormal;
- (void)dealloc
{
    [_window release];
    [super dealloc];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
// the user pressed the "Done" button, so dismiss the keyboard
[textField resignFirstResponder];
return YES;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    CGRect frame = CGRectMake(kLeftMargin, 40.0, kTextFieldWidth, kTextFieldHeight);
    textFieldNormal = [[UITextField alloc] initWithFrame:frame];
    textFieldNormal.borderStyle = UITextBorderStyleBezel;
    textFieldNormal.textColor = [UIColor blackColor];
    textFieldNormal.font = [UIFont systemFontOfSize:17.0];
    textFieldNormal.placeholder = @"<enter text>";
    textFieldNormal.backgroundColor = [UIColor whiteColor];
    textFieldNormal.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
    textFieldNormal.keyboardType = UIKeyboardTypeDefault; // use the default type input method (entire keyboard)
    textFieldNormal.returnKeyType = UIReturnKeyDone;
    textFieldNormal.clearButtonMode = UITextFieldViewModeWhileEditing; // has a clear 'x' button to the right
    textFieldNormal.tag = kViewTag; // tag this control so we can remove it later for recycled cells
    textFieldNormal.delegate = self; // let us be the delegate so we know when the keyboard's "Done" button is pressed
    // Add an accessibility label that describes what the text field is for.
    [textFieldNormal setAccessibilityLabel:NSLocalizedString(@"NormalTextField", @"")];
    [self.window addSubview:textFieldNormal];
    [self.window makeKeyAndVisible];
    return YES;
}
@end

Step 7

Finally we click on the Run button to show the output.
