NSLog(#"getHHTag %i",getHHTag);
UITextField *tempTxtFld=[healthyHeart_TxtFldAry objectAtIndex:getHHTag];
if(i<([healthyHeart_TxtFldAry count]-1))
{
int j =tempTxtFld.frame.origin.y;
healthyHeartScrollView.contentOffset=CGPointMake(0 , j);
NSLog(#"j>>>>>%i",j);

Answer 1

Firstly add tag to each and every UITextField;
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
//Take reference of all UITextField u added let say u have 3;
UITextField *txt = (UItextField *)[self.view viewWithTag:99];
UITextField *txt1 = (UItextField *)[self.view viewWithTag:199];
UITextField *txt2 = (UItextField *)[self.view viewWithTag:299];
if(textField == txt)
{
[txt1 resignFirstResponder];
[txt2 resignFirstResponder];
//required scroll view offset here
}
if(textField == txt1)
{
[txt resignFirstResponder];
[txt2 resignFirstResponder];
//required scroll view offset here
}
if(textField == txt2)
{
[txt resignFirstResponder];
[txt1 resignFirstResponder];
//required scroll view offset here
}
return YES;
}

scrollview.contentOffset is the point at which the content view is offset from the orgin scroll view. In you code
healthyHeartScrollView.contentOffset=CGPointMake(0 ,tempTxtFld.frame.origin.y);
The tempTxtFld is out of hte content view of healthyHeartScrollView. This makes the tempTxtFld.frame.orgin.y be negative relative to the contentview of healthyHeartScrollView.
So you can't see it.
ps. I really do not know what you want to do.-_-
