IOS手勢(shì)操作(拖動(dòng)、捏合、旋轉(zhuǎn)、點(diǎn)按、長(zhǎng)按、輕掃、自定義)

 更新時(shí)間:2015年07月27日 16:58:00   投稿:mrr  
這篇文章主要介紹了IOS手勢(shì)操作(拖動(dòng)、捏合、旋轉(zhuǎn)、點(diǎn)按、長(zhǎng)按、輕掃、自定義),需要的朋友可以參考下

下面通過(guò)圖文并茂的方式給大家分享下IOS手勢(shì)操作(拖動(dòng)、捏合、旋轉(zhuǎn)、點(diǎn)按、長(zhǎng)按、輕掃、自定義)的相關(guān)內(nèi)容。

1、UIGestureRecognizer 介紹
手勢(shì)識(shí)別在 iOS 中非常重要,他極大地提高了移動(dòng)設(shè)備的使用便捷性。

iOS 系統(tǒng)在 3.2 以后,他提供了一些常用的手勢(shì)(UIGestureRecognizer 的子類),開(kāi)發(fā)者可以直接使用他們進(jìn)行手勢(shì)操作。

UIPanGestureRecognizer(拖動(dòng))

UIPinchGestureRecognizer(捏合)

UIRotationGestureRecognizer(旋轉(zhuǎn))

UITapGestureRecognizer(點(diǎn)按)

UILongPressGestureRecognizer(長(zhǎng)按)

​UISwipeGestureRecognizer(輕掃)

另外,可以通過(guò)繼承 UIGestureRecognizer 類,實(shí)現(xiàn)自定義手勢(shì)(手勢(shì)識(shí)別器類)。

PS:自定義手勢(shì)時(shí),需要 #import <UIKit/UIGestureRecognizerSubclass.h>,一般需實(shí)現(xiàn)如下方法:

復(fù)制代碼 代碼如下:

- (void)reset;

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event;
//以上方法在分類 UIGestureRecognizer (UIGestureRecognizerProtected) 中聲明,更多方法聲明請(qǐng)自行查看

UIGestureRecognizer 的繼承關(guān)系如下:

2、手勢(shì)狀態(tài)
在六種手勢(shì)識(shí)別中,只有一種手勢(shì)是離散型手勢(shì),他就是 UITapGestureRecognizer。

離散型手勢(shì)的特點(diǎn)就是:一旦識(shí)別就無(wú)法取消,而且只會(huì)調(diào)用一次手勢(shì)操作事件(初始化手勢(shì)時(shí)指定的回調(diào)方法)。

​換句話說(shuō)其他五種手勢(shì)是連續(xù)型手勢(shì),而連續(xù)型手勢(shì)的特點(diǎn)就是:會(huì)多次調(diào)用手勢(shì)操作事件,而且在連續(xù)手勢(shì)識(shí)別后可以取消手勢(shì)。從下圖可以看出兩者調(diào)用操作事件的次數(shù)是不同的:

手勢(shì)狀態(tài)枚舉如下:

復(fù)制代碼 代碼如下:

typedef NS_ENUM(NSInteger, UIGestureRecognizerState) {
  UIGestureRecognizerStatePossible,  // 尚未識(shí)別是何種手勢(shì)操作(但可能已經(jīng)觸發(fā)了觸摸事件),默認(rèn)狀態(tài)
  UIGestureRecognizerStateBegan,   // 手勢(shì)已經(jīng)開(kāi)始,此時(shí)已經(jīng)被識(shí)別,但是這個(gè)過(guò)程中可能發(fā)生變化,手勢(shì)操作尚未完成
  UIGestureRecognizerStateChanged,  // 手勢(shì)狀態(tài)發(fā)生轉(zhuǎn)變
  UIGestureRecognizerStateEnded,   // 手勢(shì)識(shí)別操作完成(此時(shí)已經(jīng)松開(kāi)手指)
  UIGestureRecognizerStateCancelled, // 手勢(shì)被取消,恢復(fù)到默認(rèn)狀態(tài)
  UIGestureRecognizerStateFailed,   // 手勢(shì)識(shí)別失敗,恢復(fù)到默認(rèn)狀態(tài)
  UIGestureRecognizerStateRecognized = UIGestureRecognizerStateEnded // 手勢(shì)識(shí)別完成,同UIGestureRecognizerStateEnded
};

對(duì)于離散型手勢(shì) UITapGestureRecgnizer 要么被識(shí)別,要么失敗,點(diǎn)按(假設(shè)點(diǎn)按次數(shù)設(shè)置為1,并且沒(méi)有添加長(zhǎng)按手勢(shì))下去一次不松開(kāi)則此時(shí)什么也不會(huì)發(fā)生,松開(kāi)手指立即識(shí)別并調(diào)用操作事件,并且狀態(tài)為3(已完成)。
但是連續(xù)型手勢(shì)要復(fù)雜一些,就拿旋轉(zhuǎn)手勢(shì)來(lái)說(shuō),如果兩個(gè)手指點(diǎn)下去不做任何操作,此時(shí)并不能識(shí)別手勢(shì)(因?yàn)槲覀冞€沒(méi)旋轉(zhuǎn))但是其實(shí)已經(jīng)觸發(fā)了觸摸開(kāi)始事件,此時(shí)處于狀態(tài)0;如果此時(shí)旋轉(zhuǎn)會(huì)被識(shí)別,也就會(huì)調(diào)用對(duì)應(yīng)的操作事件,同時(shí)狀態(tài)變成1(手勢(shì)開(kāi)始),但是狀態(tài)1只有一瞬間;緊接著狀態(tài)變?yōu)?(因?yàn)槲覀兊男D(zhuǎn)需要持續(xù)一會(huì)),并且重復(fù)調(diào)用操作事件(如果在事件中打印狀態(tài)會(huì)重復(fù)打印2);松開(kāi)手指,此時(shí)狀態(tài)變?yōu)?,并調(diào)用1次操作事件。

3、使用手勢(shì)的步驟
使用手勢(shì)很簡(jiǎn)單,分為三步:

創(chuàng)建手勢(shì)識(shí)別器對(duì)象實(shí)例。創(chuàng)建時(shí),指定一個(gè)回調(diào)方法,當(dāng)手勢(shì)開(kāi)始,改變、或結(jié)束時(shí),執(zhí)行回調(diào)方法。

設(shè)置手勢(shì)識(shí)別器對(duì)象實(shí)例的相關(guān)屬性(可選部分)

添加到需要識(shí)別的 View 中。每個(gè)手勢(shì)只對(duì)應(yīng)一個(gè) View,當(dāng)屏幕觸摸在 View 的邊界內(nèi)時(shí),如果手勢(shì)和預(yù)定的一樣,那就會(huì)執(zhí)行回調(diào)方法。

PS:一個(gè)手勢(shì)只能對(duì)應(yīng)一個(gè) View,但是一個(gè) View 可以有多個(gè)手勢(shì)。建議在真機(jī)上測(cè)試這些手勢(shì),模擬器操作不太方便,可能導(dǎo)致認(rèn)為手勢(shì)失效的情況。(模擬器測(cè)試捏合和旋轉(zhuǎn)手勢(shì)時(shí),按住 option 鍵,再用觸摸板或鼠標(biāo)操作)

4、舉例說(shuō)明
功能描述:

附加到兩個(gè)圖片視圖 UIImageView 的有『拖動(dòng)』、『捏合』、『旋轉(zhuǎn)』、『點(diǎn)按』;

而『輕掃』和『自定義手勢(shì) KMGestureRecognizer』附加在根視圖 UIView 中。

拖動(dòng):進(jìn)行當(dāng)前圖片視圖位置移動(dòng)

捏合:進(jìn)行當(dāng)前圖片視圖縮放

旋轉(zhuǎn):進(jìn)行當(dāng)前圖片視圖角度旋轉(zhuǎn)

點(diǎn)按:雙擊恢復(fù)當(dāng)前圖片視圖的縮放、角度旋轉(zhuǎn)、不透明度

長(zhǎng)按:設(shè)置當(dāng)前圖片視圖的不透明度為0.7

輕掃:左右輕掃設(shè)置兩個(gè)圖片視圖為居中,同時(shí)以垂直居中的特定偏移量定位

自定義手勢(shì):撓癢功能,左右掃動(dòng)共3次或以上,設(shè)置兩個(gè)圖片視圖為居中,同時(shí)以水平居中的特定偏移量定位

效果如下:
