You can add
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
I couldn't find any existing solutions so I extended
ODRefreshControl with horizontal layout support:
I needed solution in MonoTouch (C#) so I started by source-porting ODRefreshControl and then patched it to work with horizontal layout.
Full C# source code is here, it should be straightforward to port it back to Objective C.
All I did was add an utility function and some conditions here and there.
