A question related to UITextfield
<p>11>I have loaded 10 UITextfileds through code 
2>when i click on UITextfield,requirement is that ,it should hide all the textfields below it.and keyboard moves up
3>when 2> happens at that time,user either clicks on return button or not
  It should be work for all 10 textfilds in both case back and forth
4>when 2> happens either user switch from portrait to landscape mode or portrait to       Landscape mode without or with pressing return button</p>

<p>in all thess four cases ,keyboard should hide all the UItextfield below textfield which is clicked</p>
