TextView in iPhone

Introduction

In this article I will create a Single view application. Here I use a text view from xib. Here I code for the text view and show output in iPhone.

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 Single View Application and click on Next.

Step 4

Now provide your Product Name.

Step 5

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

Step 6

Now we write the following code:

#import "ARCViewController.h"

@interface ARCViewController ()

@end

@implementation ARCViewController

- (void)viewDidLoad
{
[super viewDidLoad];
CGRect textViewFrame = CGRectMake(20.0f, 20.0f, 280.0f, 124.0f);
UITextView *textView = [[UITextView alloc] initWithFrame:textViewFrame];
textView.returnKeyType = UIReturnKeyDone;
textView.delegate = self;
[self.view addSubview:textView];
}

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
return YES;
}

- (void)textViewDidBeginEditing:(UITextView *)textView
{

textView.backgroundColor = [UIColor redColor];
}

- (BOOL)textViewShouldEndEditing:(UITextView *)textView
{

textView.backgroundColor = [UIColor yellowColor];
return YES;
}



- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{


NSCharacterSet *doneButtonCharacterSet = [NSCharacterSet newlineCharacterSet];
NSRange replacementTextRange = [text rangeOfCharacterFromSet:doneButtonCharacterSet];
NSUInteger location = replacementTextRange.location;

if (textView.text.length + text.length > 140){
if (location != NSNotFound){
[textView resignFirstResponder];
}
return NO;
}
else if (location != NSNotFound){
[textView resignFirstResponder];
return NO;
}

return YES;

}


- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{

for (UITextView *textView in self.view.subviews) {
if ([textView isFirstResponder]) {
[textView resignFirstResponder];
}
}
[super touchesBegan:touches withEvent:event];
}



@end

Step 7

Now run the application and see the output.

Step 8

Output 1 in iPhone

Output 2 in iPhone

Output 3 in iPhone
