typedef  NS\_ENUM(NSInteger, UITableViewRowActionStyle) \{

UITableViewRowActionStyleDefault =0,

UITableViewRowActionStyleDestructive =UITableViewRowActionStyleDefault,

UITableViewRowActionStyleNormal

\} NS\_ENUM\_AVAILABLE\_IOS(8\_0);

NS\_CLASS\_AVAILABLE\_IOS(8\_0)@interface UITableViewRowAction :NSObject <NSCopying>

\+ (instancetype)rowActionWithStyle:(UITableViewRowActionStyle)style title:(NSString \*)title handler:(void (^)(UITableViewRowAction \*action, NSIndexPath \*indexPath))handler;

/下面实现相关代码

(BOOL)tableView:(UITableView \*)tableView canEditRowAtIndexPath:(NSIndexPath \*)indexPath\{

returnYES;

\- (UITableViewCellEditingStyle)tableView:(UITableView \*)tableView editingStyleForRowAtIndexPath:(NSIndexPath \*)indexPath

returnUITableViewCellEditingStyleDelete;

\-(void)tableView:(UITableView \*)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath \*)indexPath\{

if (editingStyle ==UITableViewCellEditingStyleDelete) \{

\[self.dataSourceremoveObjectAtIndex:indexPath.row\];

\[self.tableViewdeleteRowsAtIndexPaths:@\[indexPath\]withRowAnimation:UITableViewRowAnimationAutomatic\];

\- (NSArray \*)tableView:(UITableView \*)tableView editActionsForRowAtIndexPath:(NSIndexPath \*)indexPath\{

//设置删除按钮

UITableViewRowAction \*deleteRowAction = \[UITableViewRowActionrowActionWithStyle:UITableViewRowActionStyleDestructivetitle:@"删除"handler:^(UITableViewRowAction \*action,NSIndexPath \*indexPath) \{
