实现Facebook messenger风格平移到全屏视图类似效果
实现Facebook messenger风格平移到全屏视图类似效果
提问于 2014-11-05 02:13:43
我已经实现了UIPageviewContoller来支持在我的屏幕的半个底部的多个视图控制器视图。现在我的问题是如何在我的页面视图控制器上支持Facebook风格的平移效果来打开这个子视图。
我想实现Facebook消息风格的效果，他们已经在相机上应用，在与手指的平底锅，我们可以使视图作为全屏。当我们平移相同的视图时，它将在视图的原始范围内进行调整。为了更好的理解，我附上了一些屏幕。
它应该支持集成的流行手势。
我可以得到类似的效果，但我已经添加了视图到主窗口，所以视图可以平移到全屏，但通过这种方法，我无法实现交互式pop iOS默认手势，这种方法是不好的，我目前的pageviewcontoller实现。
如果视图被添加到窗口中，那么如果用户按下后退按钮，那么窗口元素将不会移动，它将停留在窗口中，因此窗口方法不是很好。
有没有其他方法可以达到类似的效果？UIViewControllerInteractiveTransitioning可能会对此有所帮助吗？
提前谢谢。我知道我会从你们那里得到更好的方法，这将比向窗口添加子视图更稳定。

你有没有试过在你的子视图A中添加滑动手势？
UISwipeGestureRecognizer *swipeUp = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeScreen:)];
swipeUp.direction = UISwipeGestureRecognizerDirectionUp;
[yourSubViewA addGestureRecognizer:swipeUp];它正在处理-
- (void)didSwipeScreen:(UISwipeGestureRecognizer *)gesture {
switch (gesture.direction) {
case UISwipeGestureRecognizerDirectionUp: {
[UIView animateWithDuration:0.5 delay:0.0 options:UIViewAnimationOptionCurveLinear animations:^{
[yourSubViewA setFrame:desiredFullScreenFrame];
} completion:^(BOOL finished) {
}];
}
break;
default:
break;
}
}要恢复到默认位置，你可以使用UISwipeGestureRecognizerDirectionDown添加另一个滑动手势，也可以只是一个轻拍手势。对于副菜来说，MFSideMenu是不错的选择。

Here, i used same code for my app for video sharing (same as facebook messenger media sharing)
Create one Uiview Name as ViewCamera with one labelHoldText and three buttons
and download SCRecoder from github
import SCRecoder class here in (.h) file and do same as below
#import <UIKit/UIKit.h>
#import "SCRecorder.h"
#import "SCAudioTools.h"
#import "SCRecorderFocusView.h"
#import "SCRecordSessionManager.h"
#import "SCTouchDetector.h"
