如何使用jQuery检测单击哪个按钮

<div id="dBlock">
 <div id="dCalc">
  <input id="firstNumber" type="text" maxlength="3" />
  <input id="secondNumber" type="text" maxlength="3" />
  <input id="btn1" type="button" value="Add" />
  <input id="btn2" type="button" value="Subtract" />
  <input id="btn3" type="button" value="Multiply" />
  <input id="btn4" type="button" value="Divide" />
 </div>
</div>

注意:上面的"dCalc"块动态添加...

我收到deploy这个错误

我正在使用XCode 4.5.1.

我<UIGestureRecognizerDelegate>在.h文件和.m文件的开头添加了

@interface FirstViewController ()

@property (nonatomic, strong) UIImageView *img1;

@end

然后viewDidLoad,以UIImageView编程方式创建

self.img1 = [[UIImageView alloc] initWithFrame:CGRectMake(50, -30, 44, 44)];
[self.img1 setImage:[UIImage imageNamed:@"image1.png"]];
[self.img1 setAlpha:0.8];
[self.img1 setHidden:NO];
[self.img1 setUserInteractionEnabled:YES];
[self.img1 setTag:901];

然后

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(guessTapObject:)];
tap.numberOfTapsRequired = 1;
tap.numberOfTouchesRequired = 1;
tap.delegate = self;

[self.img1 addGestureRecognizer:tap];

[self.view addSubview:self.img1];
[self.view bringSubviewToFront:self.img1];

最后

- (void)guessTapObject:(UITapGestureRecognizer *) gesture
{
    // guessing the image
    UIImageView *tapImageView = (UIImageView*) gesture.view;
    NSLog(@"Gesture Tag: %d", tapImageView.tag); …

我正在使用 AWS Unity (v3.3.50.0)：从https://aws.amazon.com/mobile/sdk/下载的 S3 SDK (AWSSDK.S3.3.3.5.4.unitypackage) 。我的 Unity 版本是 5.5.1。

我想下载一个放在 S3 存储桶上的图像，存储桶已配置并且可以下载。我将字符串视为响应数据。

但我无法在 S3 示例 GetObject() 函数中将返回的 StreamReader 转换为 UnityEngine.UI.Image.sprite 或 UnityEngine.UI.RawImage.texture。

private void GetObject()
{
    ResultText.text = string.Format("fetching {0} from bucket {1}", SampleFileName, S3BucketName);
    Client.GetObjectAsync(S3BucketName, SampleFileName, (responseObj) =>
        {
            string data = null;
            var response = responseObj.Response;
            if (response.ResponseStream != null)
            {
                using (StreamReader reader = new StreamReader(response.ResponseStream))
                {
                    data = reader.ReadToEnd();
                }

                ResultText.text += "\n";
                ResultText.text += data;
            }
            Debug.Log("GetObject: " + data);
        }); …
