如何通过手势更改报价[重复]

Question

我正在创建在属性列表中有引号的应用程序，当我按下下一个按钮时，它会显示在 UIText 中，另一个引号会出现在 textview 中，但现在我想在用户根据该动作向左或向右滑动时添加手势引号会变得 。我是 iphone 新手。我已经使用viewpagger在android中完成了它。有没有人知道这个我该怎么做..提前谢谢。

Answer 1

您可以使用 UISwipeGestureRecognizer 来完成。 确保您的 textView 不可编辑。

代码如下：

UISwipeGestureRecognizer *leftSwipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipe)];
[leftSwipe setDirection:UISwipeGestureRecognizerDirectionLeft];
[_textView addGestureRecognizer:leftSwipe];


UISwipeGestureRecognizer *rightSwipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipe)];
[rightSwipe setDirection:UISwipeGestureRecognizerDirectionRight];
[_textView addGestureRecognizer:rightSwipe];

- (void) leftSwipe
{
    NSLog(@"leftSwipe");
}

- (void) rightSwipe
{
    NSLog(@"rightSwipe");
}

现在相应地显示您的报价。

为您的报价添加动画：

首先将 QuartzCore 框架导入您的项目。

#import <QuartzCore/QuartzCore.h>

现在修改滑动方法如下：

- (void) leftSwipe
{
NSLog(@"leftSwipe");

[self curlAnimationFromLeft];
}

- (void) rightSwipe
{
NSLog(@"rightSwipe");

[self curlAnimationFromRight];
}


- (void) curlAnimationFromLeft
{
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.0];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
animation.type = @"pageCurl";
animation.subtype = @"fromRight";
animation.fillMode = kCAFillModeForwards;
[animation setRemovedOnCompletion:YES];
[_textView.layer addAnimation:animation forKey:@"pageCurlAnimation"];
}

-(void)curlAnimationFromRight
{
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.0];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
animation.type = @"pageUnCurl";
animation.subtype = @"fromRight";
animation.fillMode = kCAFillModeForwards;
animation.startProgress = 0.35;
[animation setRemovedOnCompletion:NO];
[_textView.layer addAnimation:animation forKey:@"pageUnCurlAnimation"];
}
