Creating custom UITextView with UILabels as well as text in it

cocoa-touch, ios, iphone, objective-c, uitextview

Solution

you can create textfield using this code.

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 200, 300, 40)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = @"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;    
textField.delegate = self;
[self.view addSubview:textField];
[textField release];

And for creating label you can use this code:

CGRect labelFrame = CGRectMake( 10, 40, 100, 30 );
    UILabel* label = [[UILabel alloc] initWithFrame: labelFrame];
    [label setText: @"My Label"];
    [label setTextColor: [UIColor orangeColor]];
    label.backgroundColor =[UIColor clearColor];
    [view addSubview: label];

and for deleting label when backspace tape use this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
if ([string isEqualToString:@""]) {
NSLog(@"backspace button pressed");
[label removeFromSuperview];
}
return YES;
}

If the backspace button is pressed, then the replacementString(string) will have null value. So we can identify backspace button press using this.

Problem

I would like to create a custom `UITextView` with the ability to enter text in it, as well as programmatically adding some `UILabels` there that would act like text (I need to delete them with the 'backspace' button when the cursor comes near them). This `UITextView` should be expandable and the labels can have different width. Any ideas of how you can create this sort of thing, any tutorials or such?
