Implement a horizontal UIRefreshControl

问题

How do I go and implement a UIRefreshControl which would get refreshed when pulled from left or right side??

Is it possible with the standard UIRefreshControl? Or is there any API to create this effect? I have been searching a lot to get some lead on this but I am not able to find anything.

All I could find is this answer on SO, but it is written in C# which I am not much familiar with.

回答1:

You could use a UITableViewController that is rotated 90 degrees.

Add [self.view setTransform:CGAffineTransformMakeRotation(-M_PI / 2)]; in the UITableViewController class during setup.

Example using UITableView (and not UITableViewController):

table_ = [[UITableView alloc] initWithFrame:self.bounds];
[table_ setDelegate:self];
[table_ setDataSource:self];
[table_ registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];
[table_ setTransform:CGAffineTransformMakeRotation(-M_PI / 2)];

UIRefreshControl *ctrl = [[UIRefreshControl alloc] init];
[ctrl setBackgroundColor:[UIColor yellowColor]];
[table_ addSubview:ctrl];

[self addSubview:table_];

Make sure to remember to rotate the content back again in the opposite direction!

There are no default refreshcontrol for this. You have to create custom refreshcontrol to get this behaviour.
