iOS 簡單實作類別似於小說閱讀滑動分頁效果

廢話不多說上代碼，我們要建立一個UIViewController

typedef enum : NSUInteger {

    Fade = 1,                   //淡入淡出

    Push,                       //推擠

    Reveal,                     //揭開

    MoveIn,                     //覆蓋

    Cube,                       //立方體

    SuckEffect,                 //吮吸

    OglFlip,                    //翻轉

    RippleEffect,               //波紋

    PageCurl,                   //翻頁

    PageUnCurl,                 //反翻頁

    CameraIrisHollowOpen,       //開鏡頭

    CameraIrisHollowClose,      //關鏡頭

    CurlDown,                   //下翻頁

    CurlUp,                     //上翻頁

    FlipFromLeft,               //左翻轉

    FlipFromRight,              //右翻轉

    

} AnimationType;

各種分頁效果。

@interface ViewController (){

    NSInteger _count;//翻到的第幾頁

    NSInteger _sum;//頁面總數

    NSArray *_arr;//設定頁面背景色

}

- (void)viewDidLoad {

    [super viewDidLoad];

    _sum = 20;

    self.view.backgroundColor = [UIColor whiteColor];

    _arr = @[[UIColor redColor],[UIColor greenColor],[UIColor blueColor]];

    NSLog(@"------------------?------------第%ld頁",(long)_count);

    [self rootViewAddUISwipeGestureRecognizer];

-(void)rootViewAddUISwipeGestureRecognizer{

    UISwipeGestureRecognizer   *fromRightSwip = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(nextPage)];

    fromRightSwip.direction = UISwipeGestureRecognizerDirectionLeft;

    fromLeftSwip.direction = UISwipeGestureRecognizerDirectionRight;

    [self.view addGestureRecognizer:fromLeftSwip];

}

//實現滑動事件

-(void)nextPage{

    self.view.backgroundColor = _arr[arc4random()%3];

    if (_count<_sum-1) {

        NSString *subtypeString;

        subtypeString = kCATransitionFromRight;

        _count = _count - 1;

    } else {

        _count = 0;

    }

    NSLog(@"------------------?------------第%ld頁",(long)_count);
