I want to change the cursor position in TextView...
// NoteView objective _c class its super class is TextView...

// An empty implementation adversely affects performance during animation.

//Get the current drawing context

//Set the line color and width
// CGContextSetStrokeColorWithColor(context, [UIColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:0.2f].CGColor);

//Start a new Path
CGContextBeginPath(context);
//Find the number of lines in our textView + add a bit more height to draw lines in the empty part of the view
NSUInteger numberOfLines = (self.contentSize.height + self.bounds.size.height) / self.font.leading;
//Set the line offset from the baseline. (I'm sure there's a concrete way to calculate this.)
CGFloat baselineOffset = 6.0f;
//iterate over numberOfLines and draw each line
for (int x = 0; x < numberOfLines; x++) {
//0.5f offset lines up line with pixel boundary
CGContextMoveToPoint(context, self.bounds.origin.x, self.font.leading*x + 0.5f + baselineOffset);

}
//its a view controller class and here i imported NotesView here
#import "NotesViewController.h"

@end
@implementation NotesViewController
// i load the textView frame whatever i created class above

// in view did load i set the delegate and code for cursor position

I write all the delegate methods for Textview and ScrollView of Textview I the cursor positon is starts the vertical line after.... I'm not expressed well please understand based on images... I want cursor position... I want to set my Textview with real note application in iPhone.. I add Textview to ViewController all works well but cursor stats starting position... I want to cursor position always horizontal line........ Try to give solution based on the images..
