资源说明：Easily assign touch down, touch up, and tapped actions to UIViews using blocks.
## What is it?
`JMWhenTapped` is a simple little syntactical-sugar addition to all `UIView` objects, as well as any class that inherits from `UIView`. It allows you to assign touch-up, touch-down, tapped (touched down then up), double taps and two finger taps actions to a `UIView` object using a convenient blocks-style syntax. (Examples shown below).
## Installation
Clone the repo. Add the `JMWhenTapped` folder to your iOS 4 project. `#import "JMWhenTapped.h"` wherever you'd like to use the syntax.
## Examples & Usage
Use it like this:
[myView whenTapped:^{
NSLog(@"I was tapped!");
}];
Or like this:
[myView whenTouchedDown:^{
NSLog(@"I was touched down!");
}];
And also like this:
[myView whenTouchedUp:^{
NSLog(@"I was touched up!");
}];
This works the same way with double tap and two finger taps.
## The Different Actions
The `whenTapped:` method should be used in cases where you simply want something to happen when the user taps on a view (i.e. you are concerned with performing some action when their finger is down then up, like changing to a "pressed" state.)
The `whenDoubleTapped:` method should be used when you want to check for double taps on your view.
The `whenTwoFingerTapped:` method should be used when you want to check for single taps made with two fingers (like in Maps.app).
The `whenTouchedDown:` method should be used when you want to trigger some action when the user touches down on your view.
The `whenTouchedUp:` method should be used when you want to trigger some action when the user touches up on your view.
## Demo
Included in this repo is a demo Xcode project that illustrates a quick example of how to use `JMWhenTapped`.
