Set your view controller (or some other appropriate object) as the text field's delegate and implement the textFieldDidBeginEditing: method like this:

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    UITextPosition *beginning = [textField beginningOfDocument];
    [textField setSelectedTextRange:[textField textRangeFromPosition:beginning
                                                          toPosition:beginning]];
}

Note that setSelectedTextRange: is a protocol method of UITextInput (which UITextField implements), so you won't find it directly in the UITextField documentation.

self.selectedTextRange = [self textRangeFromPosition:newPos toPosition:newPos];

If anyone's looking for the answer in Swift: 

let desiredPosition = textField.beginningOfDocument
textField.selectedTextRange = textField.textRangeFromPosition(desiredPosition, toPosition: desiredPosition)

But I believe this only works if the cursor is already in the text field. You can use this to do that:

textField.becomeFirstResponder()
let desiredPosition = textField.beginningOfDocument
textField.selectedTextRange = textField.textRangeFromPosition(desiredPosition, toPosition: desiredPosition)
