The best way to use UIGesture
Usage
TapGesture:
because tapGesture is only have one state,so it's only have method whenTapped
view.nc_addTapGestureWithConfigClosure { (tapGestureRecognizer) -> () in
// Configure gesture recognizer,like this:
tapGestureRecognizer.numberOfTapsRequired=2
}.whenTapped {(tapGestureRecognizer) -> () in
//doSomething()
}
// or you can directly do something
view.nc_whenTapped {(tapGestureRecognizer) -> () in
//doSomething()
}
LongPress,Pan,Pinch,Rotate,Swipe,ScreenEdgesPan:
if you want to cinfigure gesture,use this method:
view.nc_addxxxxGestureWithConfigClosure({ (gestureRecognizer) -> () in
//Configure gesture recognizer
})
if you needn't configure,use this method to start:
view.nc_addxxxxGesture()
then,you can add hanlder function as you want:
view.nc_addPanGesture()
.whenBegan { (recognizer) -> Void in
}.whenCancelled { (recognizer) -> Void in
}.whenChanged { (recognizer) -> Void in
}.whenEnded { (recognizer) -> Void in
}.whenFailed { (recognizer) -> Void in
}
a convenient way to use SwipeGesture:
view.nc_whenSwipedInDirection(.Down) { (gestureRecognizer) in
}
or if you want set one handler for many states,use whenStatesHappend:
lbState.nc_addPanGesture().whenStatesHappend([.Ended,.Changed]) { (gestureRecognizer) -> Void in
}
Attention
Custom gestureRecognizerHandler is retained by UIGestureRecognizer , UIGestureRecognizer is retained by target view, so if you're using self property remeber explicit [unowned self] to avoid retain cycle:
lbState.nc_whenSwipedInDirection(.Down) {[unowned self] (gestureRecognizer) in
self.lbState.text="Down"
}
Installation
CocoaPods
To integrate NiceGesture into your Xcode project using CocoaPods, specify it in your Podfile:
platform :ios, '8.0'
use_frameworks!
pod 'NiceGesture'
Manual
Just copy the files which under NiceGesture folder to your project
Carthage
