It&#39;s the path to the directory containing the Xcode project.

That&#39;s basically your project root directory defined by Xcode.

**SRCROOT**

`$(SRCROOT)`(aka `$(SOURCE_ROOT)`) is a path to your location where a`.xcodeproj` is.

It is simple to check, just put it in a field and Xcode gives you a tip

I have the following code.

    &lt;html&gt;
    &lt;head&gt;
        &lt;script type=&quot;text/javascript&quot; src=&quot;http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js&quot;&gt;&lt;/script&gt;
    &lt;/head&gt;
    
    &lt;div id=&quot;hello&quot;&gt;Hello &lt;div&gt;Child-Of-Hello&lt;/div&gt;&lt;/div&gt;
    &lt;br /&gt;
    &lt;div id=&quot;goodbye&quot;&gt;Goodbye &lt;div&gt;Child-Of-Goodbye&lt;/div&gt;&lt;/div&gt;
    
    &lt;script type=&quot;text/javascript&quot;&gt;
    &lt;!--
    function fun(evt) {
        var target = $(evt.target);    
        if ($(&#39;div#hello&#39;).parents(target).length) {
            alert(&#39;Your clicked element is having div#hello as parent&#39;);
        }
    }
    $(document).bind(&#39;click&#39;, fun);
    --&gt;
    &lt;/script&gt;
    
    &lt;/html&gt;

I expect only when `Child-Of-Hello` being clicked, `$(&#39;div#hello&#39;).parents(target).length` will return &gt;0.

However, it just happen whenever I click on anywhere.

Is there something wrong with my code?


Check if an element is a child of a parent

I&#39;m trying to send an email using Java:

    import java.util.*;
    import javax.mail.*;
    import javax.mail.internet.*;
    import javax.activation.*;
    
    public class SendEmail {
    
       public static void main(String [] args) {
          
          // Recipient&#39;s email ID needs to be mentioned.
          String to = &quot;abcd@gmail.com&quot;;
    
          // Sender&#39;s email ID needs to be mentioned
          String from = &quot;web@gmail.com&quot;;
    
          // Assuming you are sending email from localhost
          String host = &quot;localhost&quot;;
    
          // Get system properties
          Properties properties = System.getProperties();
    
          // Setup mail server
          properties.setProperty(&quot;mail.smtp.host&quot;, host);
    
          // Get the default Session object.
          Session session = Session.getDefaultInstance(properties);
    
          try{
             // Create a default MimeMessage object.
             MimeMessage message = new MimeMessage(session);
    
             // Set From: header field of the header.
             message.setFrom(new InternetAddress(from));
    
             // Set To: header field of the header.
             message.addRecipient(Message.RecipientType.TO,
                                      new InternetAddress(to));
    
             // Set Subject: header field
             message.setSubject(&quot;This is the Subject Line!&quot;);
    
             // Now set the actual message
             message.setText(&quot;This is actual message&quot;);
    
             // Send message
             Transport.send(message);
             System.out.println(&quot;Sent message successfully....&quot;);
          }catch (MessagingException mex) {
             mex.printStackTrace();
          }
       }
    }

I am getting the error :

    javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25;
      nested exception is:java.net.ConnectException: Connection refused: connect
            at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1706)
            at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:525)

Will this code work to send email?

I am looking at an Xcode project that uses some libraries.  The project was created on a different computer, so I need to update some paths.  The library search paths all start with `$(SRCROOT)`.  What does that mean?

I&#39;d like to show the current language that the device UI is using. What code would I use? 

I want this as an `NSString` in fully spelled out format. (Not @&quot;en_US&quot;)

EDIT: For those driving on by, there are a ton of useful comments here, as the answer has evolved with new iOS releases.

Getting current device language in iOS?

I used to be able to type with my real mac keyboard after launching the iPhone Simulator. Typing with the on-screen simulator keyboard is just horrible when testing with large amounts of text.

No matter what I do, I can&#39;t get my keyboard to type anymore inside the simulator. Even if I have &quot;Simulate Hardware Keyboard&quot; switched ON, it just won&#39;t type anything. Can someone please tell me what I&#39;m doing wrong? Is there no way to type using the real keyboard anymore?

This seems like such a basic task, but I&#39;m stumped.

How, in Xcode, do you execute a textual search though (the XML contents of) all the .xib files in a project?

For example, all of our .xib files contain this string on the second line: `com.apple.InterfaceBuilder3.CocoaTouch.XIB`. So I&#39;d think that searching all project files for that string would return all .xib files, but Xcode insists &quot;0 occurrences&quot;. I&#39;ve double checked that the Project Find Options look correct.

I must be missing something obvious. (Or Xcode is somehow hard-coded to skip .xib files.)

I&#39;m trying to find all the .xib files that reference a particular class (and a text search seems like the most direct way).

Thanks!

If I added a user-defined setting in my build configuration, how can I read that setting in my Objective-C code?

I have two files in my project, `debug.plist` and `release.plist`. I want my `MainApp.m` file to read one of these files based on which build configuration is running. I set up a user-defined setting named &quot;filename&quot; in both the Debug and Release configurations to point to the appropriate file. But I don&#39;t know how my `MainApp.m` file can read the filename variable from the current running configuration.

Getting the folder name from a full filename path

I am looking for some advice as to the best way to generate a file path using variables, currently my code looks similar to the following:

    path = /my/root/directory
    for x in list_of_vars:
            if os.path.isdir(path + &#39;/&#39; + x):  # line A
                print(x + &#39; exists.&#39;)
            else:
                os.mkdir(path + &#39;/&#39; + x)       # line B
                print(x + &#39; created.&#39;)

For lines A and B as shown above, is there a better way to create a file path as this will become longer the deeper I delve into the directory tree?

I envisage an existing built-in method to be used as follows:

    create_path(path, &#39;in&#39;, &#39;here&#39;)

producing a path of the form `/my/root/directory/in/here`

If there is no built in function I will just write myself one.

Thank you for any input.


Create file path from variables

I had to split up a long css file. I put the smaller css files within a `styles` directory.

Now I have to update the the urls to go up one level with the `../` notation.

Is there anyway to specify the base URL from which to load assets like with the base tag in HTML, but with CSS?

Specifying base url for css

Is there anything built into `System.IO.Path` that gives me just the filepath?

For example, if I have a `string` 

&gt; @&quot;c:\webserver\public\myCompany\configs\promo.xml&quot;,

 

is there any BCL method that will give me 

&gt; &quot;c:\webserver\public\myCompany\configs\&quot;?

Get full path without filename from path that includes filename

Question: is there a simple sh/bash/zsh/fish/... command to print the absolute path of whichever file I feed it?

Usage case: I&#39;m in directory `/a/b` and I&#39;d like to print the full path to file `c` on the command-line so that I can easily paste it into another program: `/a/b/c`. Simple, yet a little program to do this could probably save me 5 or so seconds when it comes to handling long paths, which in the end adds up. So it surprises me that I can&#39;t find a standard utility to do this — is there really none?

Here&#39;s a sample implementation, abspath.py:

    #!/usr/bin/python
    # Author: Diggory Hardy &lt;diggory.hardy@gmail.com&gt;
    # Licence: public domain
    # Purpose: print the absolute path of all input paths

    import sys
    import os.path
    if len(sys.argv)&gt;1:
        for i in range(1,len(sys.argv)):
            print os.path.abspath( sys.argv[i] )
        sys.exit(0)
    else:
        print &gt;&gt; sys.stderr, &quot;Usage: &quot;,sys.argv[0],&quot; PATH.&quot;
        sys.exit(1)
