UITableViewCell setAccessoryType example in Objective C (iOS).

UITableViewCell setAccessoryType

The type of standard accessory view the cell should use (normal state).

@property(nonatomic) UITableViewCellAccessoryType accessoryType

Discussion of [UITableViewCell setAccessoryType]
The accessory view appears in the right side of the cell in the table view’s normal (default) state. The standard accessory views include the disclosure chevron; for a description of valid accessoryType constants, see “Cell Accessory Type.” The default is UITableViewCellAccessoryNone. If a custom accessory view is set through the accessoryView property, the value of this property is ignored. If the cell is enabled and the accessory type is UITableViewCellAccessoryDetailDisclosureButton, the accessory view tracks touches and, when tapped, sends the data-source object a tableView:accessoryButtonTappedForRowWithIndexPath: message.[UITableViewCell setAccessoryType]

The accessory-type image cross-fades between normal and editing states if it set for both states; use the editingAccessoryType property to set the accessory type for the cell during editing mode. If this property is not set for both states, the cell is animated to slide in or out, as necessary.
