項(xiàng)目里面有一個(gè)接受消息然后將消息內(nèi)容以翻頁(yè)的形式展現(xiàn)給用戶,返回的數(shù)據(jù)就是簡(jiǎn)單的文字沒(méi)有圖片,所以我就簡(jiǎn)單的用了textView接收然后在view上設(shè)置了翻頁(yè)效果的切換動(dòng)畫(huà),這個(gè)翻頁(yè)切換也比較簡(jiǎn)單,就是用了一下系統(tǒng)的動(dòng)畫(huà).
效果如圖:

大體思路:
在self.view 上放置一個(gè)label,label.text從數(shù)組中獲得,當(dāng)點(diǎn)擊上下頁(yè)按鈕的時(shí)候,改變label.text,并且執(zhí)行翻頁(yè)效果動(dòng)畫(huà).
主要代碼:
#pragma mark - 下一頁(yè)按鈕響應(yīng)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:@"已經(jīng)是最后一頁(yè)咯,親(づ￣ 3￣)づ"];
}
NSLog(@"%ld", (long)_count);
}
#pragma CATransition動(dòng)畫(huà)實(shí)現(xiàn)
/**
* 動(dòng)畫(huà)效果實(shí)現(xiàn)
*
* @param type 動(dòng)畫(huà)的類型 在開(kāi)頭的枚舉中有列舉,比如 CurlDown//下翻頁(yè),CurlUp//上翻頁(yè)
,FlipFromLeft//左翻轉(zhuǎn),FlipFromRight//右翻轉(zhuǎn) 等...
* @param subtype 動(dòng)畫(huà)執(zhí)行的起始位置,上下左右
* @param view 哪個(gè)view執(zhí)行的動(dòng)畫(huà)
*/
- (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"];
}
主要就是熟悉一下簡(jiǎn)單動(dòng)畫(huà)的實(shí)現(xiàn)了
本項(xiàng)目gitHub地址:https://github.com/irembeu/PageBlurDemo.git
//2 添加啟動(dòng)頁(yè)和手勢(shì)控制的翻頁(yè)效果實(shí)現(xiàn),添加swipe手勢(shì)后畫(huà)面切換更生動(dòng).
效果圖:

#pragma mark - 手勢(shì)
- (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];
}
//判斷是否是第一次進(jìn)入程序
if (![[[NSUserDefaults standardUserDefaults] objectForKey:@"isFirst"] isEqualToString:@"yes"]) {
//顯示提示
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"tishi" message:@"" delegate:self cancelButtonTitle:@"曉得了" otherButtonTitles: nil];
[alert show];
[[NSUserDefaults standardUserDefaults]setObject:@"yes" forKey:@"isFirst"];
}
動(dòng)畫(huà)效果和上一個(gè)是一種效果,具體代碼請(qǐng)看我的gibHub,和上一個(gè)項(xiàng)目在一個(gè)地址里面,這個(gè)在 SwipeGesturePageBlurDemo 分支中.
