Ios 可以使用平移手势移动窗口吗？

是否可以通过平移手势识别器移动

ui窗口

？我在理解手势的工作原理方面遇到了一些问题，并设法使其在视图中工作，但在windows中却不工作。

是的，你可以

UIWindow

是

UIView

的子类，您可以正常添加

PanGesture

。若要移动窗口，请更改

UIApplication.sharedApplication.delegate.window的框架，它将正常工作

创建一个新项目并用下面的“我的代码”替换
AppDelegate.m
文件。你们可以移动窗户

#import "AppDelegate.h"

@interface AppDelegate ()

@property (nonatomic, strong) UIPanGestureRecognizer* panGesture;
@property (nonatomic, assign) CGPoint lastPoint;

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Override point for customization after application launch.

  self.panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanGesture:)];
  [self.window addGestureRecognizer:_panGesture];
  _needUpdate = YES;

  return YES;
}

- (void)handlePanGesture:(UIPanGestureRecognizer *)panGesture {
  CGPoint point = [panGesture locationInView:self.window];
  CGPoint center = self.window.center;

  if (CGPointEqualToPoint(_lastPoint, CGPointZero)) {
    _lastPoint = point;
  }

  center.x += point.x - _lastPoint.x;
  center.y += point.y - _lastPoint.y;
  self.window.frame = [UIScreen mainScreen].bounds;
  self.window.center = center;

  if (panGesture.state == UIGestureRecognizerStateEnded) {
    _lastPoint = CGPointZero;
  }
}

嘿，谢谢你的回复。这使它部分起作用。但它在起点和新起点之间跳跃。安迪，你知道为什么吗？好像要把它设定成both@KaneBuckthorpe我已经更新了答案。你可以再查一下。请让我知道它是否有效；）很好用！！非常感谢。这已经困扰了我很多年了哈哈，谢谢你的回复。这使它部分起作用。但它在起点和新起点之间跳跃。安迪，你知道为什么吗？好像要把它设定成both@KaneBuckthorpe我已经更新了答案。你可以再查一下。请让我知道它是否有效；）很好用！！非常感谢。这困扰了我好几年了哈哈
