You need to escape the special characters to make it work properly. Something like:

    [NSURL URLWithString:[googlSearchString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

Use this for **SWIFT** 4:

    let url = myURLString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
    let myURL = URL(string: url)


&gt; **Using Swift 2.2**

For escaping *non-english* characters, for example: *to make an URL request* do:

`let urlPath = path.URLString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())`

Here `urlPath` is an `Optional` and `path` is your original url (the one with non-english characters)


In 2k16 method `stringByAddingPercentEscapesUsingEncoding:` is deprecated and there is no way escape this correctly. When URL is predefined just use browser encoded string, because `stringByAddingPercentEncodingWithAllowedCharacters:` method cannot escape whole URL.

Some times a space in the url can cause this problem . 

I use Visual Studio as my editor for .css and .js files.. It ***REALLY SUCKS*** especially with .js files since it insists on indenting them in a very weird way, but I find it convenient that the first alt-tab is always the browser instead of another editor, and that ctrl-tab is always either the code file or the css/js.

Anyways, in all its radiant wisdom it decides to check them for syntax errors as well and every time I compile my project it gives several &quot;errors&quot; that push down the real errors of the compilation, so every time I make a syntax error in a code file I have to scroll down through all the js/css errors to see what&#39;s wrong.

Examples of such errors (that aren&#39;t really errors) are:
&lt;pre&gt;
Error	7	Validation (CSS 2.1): &#39;text-rendering&#39; is not a known CSS property name.
Error	8	Validation (CSS 2.1): &#39;opacity&#39; is not a known CSS property name.
&lt;/pre&gt;

The situation also got much worse recently, since it now keeps parsing a .js file as a .css file for some reason, so I get errors such as:

&lt;pre&gt;
Error	1	Unexpected character sequence. Expected a selector for the style rule.	E:\Dev\anacletus\Static\set_focus.js	2
Error	2	Unexpected character sequence. Expected a property name for the &quot;&lt;property&gt; : &lt;value&gt;&quot; declaration.	E:\Dev\anacletus\Static\set_focus.js	3
Error	3	Validation (CSS 2.1): &#39;set-focus&#39; is not a known CSS property name.	E:\Dev\anacletus\Static\set_focus.js	3
&lt;/pre&gt;

I even deleted that particular file from the solution (it&#39;s not there anymore anywhere), but it keeps parsing it anyway.

**In short, how can I disable this feature?**

How to make Visual Studio stop &quot;compiling&quot; .js and .css files

I am currently trying to add a progress bar to a command line script and I&#39;ve tried various solutions (including Zend and Console_ProgressBar). The problem they both have in common is that the progress bar doesn&#39;t stick at the bottom of the window because during the script, new lines and other information is outputted.

Is there any way to keep the progress bar at the bottom of the terminal but still be able to output other information while the script is running?

[Edit]

I figured it out:

Instead of outputting directly to STDOUT I am actually grabbing the output inside a variable, I erase the screen with `echo chr(27) . &#39;[2J&#39;` and then output to STDOUT the contents of the variable and then append my progress bar.

Hope that makes sense :)

I have the following string...

    NSString *googleSearchString = @&quot;http://www.google.com/search?q=lyrics+%22T&#230;nder+P&#229;+Dig%22+%22Jakob+Sveistrup%22&quot;;

Notice that it has some accented characters. When I try to turn that into a url the returned url is null...

    [NSURL URLWithString:googleSearchString];

So normally the url works except when there are accented non-english characters in the string. Any help on how to handle that?

How can I get the number of times an NSString (for example, `@&quot;cake&quot;`) appears in a larger NSString (for example, `@&quot;Cheesecake, apple cake, and cherry pie&quot;`)?

I need to do this on a lot of strings, so whatever method I use would need to be relatively fast.

Thanks!

What is the best way to rename the app so that the title below the app icon can have spaces but the build files doesn&#39;t have spaces. (ie, title is &quot;My Project&quot; and build file is MyProject.app)

I changed PRODUCT_NAME but when I do that the app file also contains spaces.

Renaming all the fields seems to work fine except I can&#39;t find EXECUTABLE_NAME which is the default value for &quot;Executable file&quot;.

Thank you,

iPhone XCode - How to change title below app icon

I am getting more than a little sick of this iPhone SDK and its documentation...

I am calling AudioConverterNew

in the documentation under Returns: it says &quot;returns a status code&quot;
...
really...

so far, through playing around with the parameters I have only been able to get two different errors neither of which are listed at the bottom of the Audio Converter reference.

they are &#39;mrep&#39; and &#39;?tmf&#39; (casting the OSStatus to a char array) but the specific codes aren&#39;t really the point.

as far as I can tell, random error codes are defined in random files, so you can&#39;t just search one file, I can&#39;t find a help document that just lets you search for an error code to get more info, and from what I can tell, in OS X you can use GetMacOSStatusErrorString() to convert an error to something useful, but there is no iPhone equivalent?

any help would be greatly appreciated.

EDIT:

ok, so casting them gives them in reverse (something I checked for &#39;mrep&#39; but was not there either way round) , fmt? is in the list for the Audio Converter api, and is pretty self explanatory if a bit vague, but fair enough, still &#39;perm&#39; isn&#39;t there (although it might be something to do with the simulator not supporting aac decoding) and my general question still stands.

I want to do some drawing of NSAttributedStrings in fixed-width boxes, but am having trouble calculating the right height they&#39;ll take up when drawn. So far, I&#39;ve tried:

1. Calling &lt;code&gt;- (NSSize) size&lt;/code&gt;, but the results are useless (for this purpose), as they&#39;ll give whatever width the string desires.

2. Calling &lt;code&gt;- (void)drawWithRect:(NSRect)rect options:(NSStringDrawingOptions)options&lt;/code&gt; with a rect shaped to the width I want and &lt;code&gt;NSStringDrawingUsesLineFragmentOrigin&lt;/code&gt; in the options, exactly as I&#39;m using in my drawing. The results are ... difficult to understand; certainly not what I&#39;m looking for. (As is pointed out in a number of places, including &lt;A HREF=&quot;http://lists.apple.com/archives/cocoa-dev/2006/Apr/msg01540.html&quot;&gt;this&lt;/a&gt; Cocoa-Dev thread).

3. Creating a temporary NSTextView and doing:  
    &lt;code&gt;[[tmpView textStorage] setAttributedString:aString];  
    [tmpView setHorizontallyResizable:NO];  
    [tmpView sizeToFit]; &lt;/code&gt;  
When I query the frame of tmpView, the width is still as desired, and the height is often correct ... until I get to longer strings, when it&#39;s often half the size that&#39;s required. (There doesn&#39;t seem to be a max size being hit: one frame will be 273.0 high (about 300 too short), the other will be 478.0 (only 60-ish too short)).

I&#39;d appreciate any pointers, if anyone else has managed this.

I have a text file containing unwanted null characters (ASCII NUL, `\0`). When I try to view it in `vi` I see `^@` symbols, interleaved in normal text. How can I:

1. Identify which lines in the file contain null characters? I have tried grepping for `\0` and `\x0`, but this did not work.

2. Remove the null characters? Running `strings` on the file cleaned it up, but I&#39;m just wondering if this is the best way?

How to write character &amp; in android strings.xml

since the beginning of my programmation, I used some special character like &quot;&lt;-&quot;, &quot;&quot;&lt;&lt;&quot; im my string.xml in Eclipse while developping for Android.

All worked fine for one year, but today, i just wanted to make some minor changes and began to edit my xml files.

I get now compilation error on these characters because eclipse believe it&#39;s part of the xml blocks.


Any idea on how I could add this symbol &quot;&lt;&quot; in my xml files?

What was the original historical use of the vertical tab character (`\v` in the C language, ASCII 11)?

Did it ever have a key on a keyboard? How did someone generate it?

Is there any language or system still in use today where the vertical tab character does something interesting and useful?

I have a URL in an iPhone application to work with. But the problem is that it has some spaces in the URL. I want to replace the spaces with &#39;%20&#39;. I know that there are the `stringByReplacingOccurencesOfString` and `stringByAddingPercentEscapesUsingEncoding` methods. I also have used them. But they are not working for me. The spaces are replaced by some unusual values.

I&#39;m applying those methods on an instance of `NSString`.

Parse NSURL query property

Let&#39;s say I have an `NSURL`? Whether or not it already has an empty query string, how do I add one or more parameters to the `query` of the `NSURL`? I.e., does anyone know of an implementation of this function?

    - (NSURL *)URLByAppendingQueryString:(NSString *)queryString

So that it satisfies this `NSURL+AdditionsSpec.h` file:

    #import &quot;NSURL+Additions.h&quot;
    #import &quot;Kiwi.h&quot;
    
    SPEC_BEGIN(NSURL_AdditionsSpec)
    
    describe(@&quot;NSURL+Additions&quot;, ^{
        __block NSURL *aURL;
    
        beforeEach(^{
            aURL = [[NSURL alloc] initWithString:@&quot;http://www.example.com&quot;];
            aURLWithQuery = [[NSURL alloc] initWithString:@&quot;http://www.example.com?key=value&quot;];
        });
    
        afterEach(^{
            [aURL release];
            [aURLWithQuery release];
        });
    
        describe(@&quot;-URLByAppendingQueryString:&quot;, ^{
            it(@&quot;adds to plain URL&quot;, ^{
                [[[[aURL URLByAppendingQueryString:@&quot;key=value&amp;key2=value2&quot;] query] should]
                 equal:@&quot;key=value&amp;key2=value2&quot;];
            });
    
            it(@&quot;appends to the existing query sting&quot;, ^{
                [[[[aURLWithQuery URLByAppendingQueryString:@&quot;key2=value2&amp;key3=value3&quot;] query] should]
                 equal:@&quot;key=value&amp;key2=value2&amp;key3=value3&quot;];

Objective-C: How to add query parameter to NSURL?

I have an app where the user can choose an image either from the built-in app images or from the iphone photo library. I use an object Occasion that has an `NSString` property to save the `imagePath`. 

Now in the case of the built-in app images I do get the file name as an `NSString` an save in the `[occasion imagePath]`. But in the 2nd case where the user picks an image form the photo library I get an `NSURL` which I want to convert to an `NSString` to be able to save it in `[occasion imagePath`].

Is it possible to convert the `NSURL` to an `NSString`?
