【问题描述】：

我正在使用 UITouch 移动一些 UIImageview。 我想在图像位于特定区域内时播放声音。最简单的方法是什么？ 感谢您的任何回答。

// ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize imageView1,imageView2;

- (void)viewDidLoad 
    [super viewDidLoad];



- (void)didReceiveMemoryWarning 
    [super didReceiveMemoryWarning];



- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 

    UITouch *touch = [[event allTouches] anyObject];

    CGPoint touchLocation = [touch locationInView:self.view];

    if ([touch view] == imageView1)  

        imageView1.center = touchLocation;

    

    else if ([touch view] == imageView2) 

        imageView2.center = touchLocation;

    



@end

// ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

    UIImageView *imageView1;

    UIImageView *imageView2;



@property(nonatomic,retain) IBOutlet UIImageView *imageView1;

@property(nonatomic,retain) IBOutlet UIImageView *imageView2;

@end

【参考方案1】：

我是这样解决的：

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
UITouch *touch = [[event allTouches] anyObject];

CGPoint touchLocation = [touch locationInView:self.view];
NSLog(@"%@", NSStringFromCGPoint(touchLocation));

[self.view bringSubviewToFront:imageView1];


if ([touch view] == imageView1) 

    imageView1.tag=0;

    if ((touchLocation.x >= 340 && touchLocation.x <= 420) && (touchLocation.y  >= 185 && touchLocation.y <= 265)) 
        NSLog(@"head");

        [UIView animateWithDuration:0.35
                              delay:0.0
                            options: UIViewAnimationOptionAllowAnimatedContent
                         animations:^
                             imageView1.frame = CGRectMake(380.0-43, 225.0-54, 90.0, 108.0);
                             imageView1.tag=1;

                         
                         completion:^(BOOL finished)
                             NSLog(@"Auto justerad!");
                         ];
