在UIView之间滑动手势
我有一个ViewController类，我在self.view上有一个名为templateView的UIView，它包含一个名为gridView的UIView，这里我需要在templateView上滑动，因为我已经添加了swipegesture，
swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRightAction)]; swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeftAction)]; swipeRight.direction = UISwipeGestureRecognizerDirectionRight; swipeRight.delegate = self; swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft; swipeLeft.delegate = self; [templateView addGestureRecognizer:swipeRight]; [templateView addGestureRecognizer:swipeLeft];
在swipeRight和swipeLeft我需要移动swipeLeft左侧和右侧..我需要在这些方法中实现..？
我建议
-
使用带参数的手势处理程序（如果您将手势添加到多个视图中）;
-
确保有问题的视图已打开
userInteractionEnabled。 -
除非您正在实现其中一个
UIGestureRecognizerDelegate方法，否则无需设置手势的delegate。
因此，配置可能如下所示：
templateView.userInteractionEnabled = YES; swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; swipeRight.direction = UISwipeGestureRecognizerDirectionRight; [templateView addGestureRecognizer:swipeRight]; swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft; [templateView addGestureRecognizer:swipeLeft];
然后手势处理程序可能如下所示：
- (void)handleSwipe:(UISwipeGestureRecognizer *)gesture { CGRect frame = self.gridView.frame; // I don't know how far you want to move the grid view. // This moves it off screen. // Adjust this to move it the appropriate amount for your desired UI if (gesture.direction == UISwipeGestureRecognizerDirectionRight) frame.origin.x += self.view.bounds.size.width; else if (gesture.direction == UISwipeGestureRecognizerDirectionLeft) frame.origin.x -= self.view.bounds.size.width; else NSLog(@"Unrecognized swipe direction"); // Now animate the changing of the frame [UIView animateWithDuration:0.5 animations:^{ self.gridView.frame = frame; }]; }
请注意，如果您正在使用自动布局，并且如果视图是由约束而不是translatesAutoresizingMaskIntoConstraints定义的，则此处理程序代码必须进行适当更改。 但希望这能为您提供基本的想法。
您可以使用一些UIViewAnimations移动gridView。 创建这样的东西：
-(void)swipeRightAction{ [UIView setAnimationDuration:1]; gridView.frame = CGRectMake(320,0); [UIView commitAnimations]; }
此代码将更改gridView的框架。 您需要根据要滑动视图的位置更改此参数。 我没有尝试代码，让我知道它是否有效。
