项目里面有一个接受消息然后将消息内容以翻页的形式展现给用户,返回的数据就是简单的文字没有图片,所以我就简单的用了textView接收然后在view上设置了翻页效果的切换动画,这个翻页切换也比较简单,就是用了一下系统的动画.

效果如图:

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.

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"];

}

//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.
