The overlay view displayed on the left side of the text field.
@property(nonatomic, retain) UIView *leftView
Discussion
You can use the left overlay view to indicate the intended behavior of the text field. For example, you might display a magnifying glass in this location to indicate that the text field is a search field.
The left overlay view is placed in the rectangle returned by the leftViewRectForBounds: method of the receiver. The image associated with this property should fit the given rectangle. If it does not fit, it is scaled to fit. If you specify a control for your view, the control tracks and sends actions as usual.
Availability
Available in iOS 2.0 and later.
