MNTPullToReact

MNTPullToReact is an extended evolution of the famous Pull to Refresh interaction. The main idea comes from a unique question: can the natural pulling gesture do more than just refresh and therefore avoid ugly action buttons that take up precious content space?

You can bind as many reactions as you'd like to MNTPullToReact and have your user access specific application actions through this unique and well known gesture.

MNTPullToReact is very easy to use and highly customizable.

Demo

Easy to use

MNTPullToReact is a subclass of UIControl and embraces the common target-action design pattern widely used in Apple's own controls. It also mimics the Apple UIRefreshControl control interface to facilitate its usage by developers already familiar with the Apple Pull to Refresh control.

What	UIRefreshControl	MNTPullToReact
Property to know the status	BOOL refreshing	NSInteger action
Initiate an action	beginRefreshing	beginAction:
Terminate an action	endRefreshing	endAction:
Event on action needed	UIControlEventValueChanged	UIControlEventValueChanged

Short code sample

Here is a short code sample that uses the MNTPullToReactDefaultView under the hood. The following code creates a pull to react with 4 actions.

// Import the library header
#import "PullToReact.h"

// In the viewDidLoad create the control
MNTPullToReactControl *reactControl = [[MNTPullToReactControl alloc] initWithNumberOfActions:4];
[reactControl addTarget:self action:@selector(reaction:) forControlEvents:UIControlEventValueChanged];
self.tableView.reactControl = reactControl;

// Than create the target-action method
- (void)reaction:(id)sender
{
    // Do the reaction thing
    [reactControl endAction:reactControl.action];
}

Step by step usage

• Add it to your project

If you use CocoaPods, add this line to your Podfile:

pod 'MNTPullToReact', '~> 1.0'

If you don't use CocoaPods, then add all of the required files to your project and set the needed settings according to the podspec of the library. Please note: do not forget to add -ObjC to the other linker flags.

OTHER_LDFLAGS -ObjC

• In your view controller or your subclass, import the library header.

#import "PullToReact.h"

• Set the new reactControl property of the UITableView class to the Pull to React you want to use.

MNTPullToReactControl *reactControl = [[MNTPullToReactControl alloc] initWithNumberOfActions:4];
[reactControl addTarget:_delegateAndDataSource action:@selector(reaction:) forControlEvents:UIControlEventValueChanged];
self.reactControl = reactControl;

• Add the target class to the action method implementation.

#pragma mark - Pull to react target-action method
- (void)reaction:(id)sender
{
    MNTPullToReactControl *reactControl = (MNTPullToReactControl *)sender;
    NSLog(@"Doing action %ld", (long)reactControl.action);
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
        usleep(1100 * 1000);
        dispatch_async(dispatch_get_main_queue(), ^{
            [reactControl endAction:reactControl.action];
        });
    });
}

Once your asynchronous task has terminated, do not forget to call the endAction: method to inform the Pull to React control.

Highly customizable

You can customize your own Pull to React features without any limits by subclassing the MNTPullToReactView class.

To see how to make amazing Pull to React designs, you can go through the [examples](https://github.com/mentionapp/mntpulltoreact/tree/master/ExampleCustomContent) provided in the library. ## To-do - Improve and finish the documentation to get it added to http://cocoadocs.org/. - Extended the library to be able to have a Pull to React control above a `UIWebView`. - Add the ability to put Pull to React controls on other sides of the targeted view (on the left, on the right, and at the bottom).
