当按钮移动时移动uiview

Question

我正在编写一个可以在屏幕上拖动的自定义UIButton。当我按下此按钮时，uiview将被添加到superview中。我为这个视图添加了平移手势，所以它也可以拖动。 现在我想让uiview和按钮同时可以拖动。我该怎么办？
例如：

• 如果我将uiview或按钮拖动到一个点，另一个也会移动。您可以在下面看到更多信息

Answer 1

我会将按钮和视图封装在父透明UIView中。将摇摄手势添加到它并移动它们......然后它们都会移动。

Answer 2

我为你的应用程序尝试了示例代码。它工作正常。当你拖动按钮时，视图也会同时移动。

首先我创建了按钮和UIView.I连接了它。

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIButton *btnDragg;
- (IBAction)actionDragg:(id)sender;
@property (strong, nonatomic) IBOutlet UIView *viewDrag;

@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController


@synthesize btnDragg,viewDrag;

- (void)viewDidLoad 
{
   [super viewDidLoad];
   // Do any additional setup after loading the view, typically from a nib.
   UIPanGestureRecognizer *panRecognizer;
   panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(wasDragged:)];
   panRecognizer.cancelsTouchesInView = YES;
   [btnDragg addGestureRecognizer:panRecognizer];
}


- (void)wasDragged:(UIPanGestureRecognizer *)recognizer
{
   UIButton *button = (UIButton *)recognizer.view;

   CGPoint translation = [recognizer translationInView:button];
   CGPoint translationView = [recognizer translationInView:viewDrag];
   button.center = CGPointMake(button.center.x + translation.x, button.center.y + translation.y);
   viewDrag.center = CGPointMake(viewDrag.center.x + translationView.x, viewDrag.center.y + translationView.y);

   [recognizer setTranslation:CGPointZero inView:button];
   [recognizer setTranslation:CGPointZero inView:viewDrag];
}

在我拖动按钮之前，它处于原始位置

然后当我拖动按钮时，视图也会随按钮一起移动。现在，我拖动按钮后会改变位置。
