iOS实现翻页效果动画实例代码-移动开发

本篇文章主要介绍了iOS实现翻页效果动画实例代码，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

大体思路:

在self.view 上放置一个label,label.text从数组中获得,当点击上下页按钮的时候,改变label.text,并且执行翻页效果动画.

效果如图:

主要代码:


#pragma mark - 下一页按钮响应事件
- (void)nextPage:(UIButton *)btn {
  _forwardBtn.enabled = YES;
  if (_count<_arr.count-1) {
    btn.enabled = YES;
    _label.text = [_arr objectAtIndex:_count+1];
    NSString *subtypeString;
    subtypeString = kCATransitionFromRight;
    [self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view];
    _count = _count + 1;
  } else {
    _count = _arr.count - 1;
    btn.enabled = NO;
    [self showAlert:@"已经是最后一页咯,亲(づ￣ 3￣)づ"];
  }
  NSLog(@"%ld", (long)_count);

}

#pragma CATransition动画实现
/**
 * 动画效果实现
 *
 * @param type  动画的类型 在开头的枚举中有列举,比如 CurlDown//下翻页,CurlUp//上翻页
,FlipFromLeft//左翻转,FlipFromRight//右翻转 等...
 * @param subtype 动画执行的起始位置,上下左右
 * @param view  哪个view执行的动画
 */
- (void) transitionWithType:(NSString *) type WithSubtype:(NSString *) subtype ForView : (UIView *) view {
  CATransition *animation = [CATransition animation];
  animation.duration = 0.7f;
  animation.type = type;
  if (subtype != nil) {
    animation.subtype = subtype;
  }
  animation.timingFunction = UIViewAnimationOptionCurveEaseInOut;
  [view.layer addAnimation:animation forKey:@"animation"];
}

主要就是熟悉一下简单动画的实现了

2 添加启动页和手势控制的翻页效果实现,添加swipe手势后画面切换更生动.

效果图:


#pragma mark - 手势
- (void)configTapGes {
  _fromRightSwip = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(nextPage:)];
  _fromRightSwip.direction = UISwipeGestureRecognizerDirectionLeft;
  [self.view addGestureRecognizer:_fromRightSwip];

  _fromLeftSwip = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(forwardPage:)];
  _fromLeftSwip.direction = UISwipeGestureRecognizerDirectionRight;
  [self.view addGestureRecognizer:_fromLeftSwip];
}
//判断是否是第一次进入程序
if (![[[NSUserDefaults standardUserDefaults] objectForKey:@"isFirst"] isEqualToString:@"yes"]) {
      //显示提示
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"tishi" message:@"" delegate:self cancelButtonTitle:@"晓得了" otherButtonTitles: nil];
    [alert show];
    [[NSUserDefaults standardUserDefaults]setObject:@"yes" forKey:@"isFirst"];
  }

动画效果和上一个是一种效果,具体代码请看我的gibHub,和上一个项目在一个地址里面,这个在 SwipeGesturePageBlurDemo 分支中.
