I tried everything to convert JSON response to Chinese language but not getting any success. I need to display those string in uilabel.
This is the response I'm getting:
sentence = "\U00e6\U201a\U00a8\U00e5\U00a5\U00bd\U00e3\U20ac\U201a";
pinyin = "n\U00c3\U00adn h\U00c4\U0192o"
Converting sentence's string should be like 您好 but I'm getting 您好。
For pinyin I'm getting exactly right string [[nín hăo]] in label without converting but for sentence it gives me wrong value.
I'm using XCode 7.1 and my deployment target is 8.0.
Hi thanks all for helping and trying :) i ended up solving my own problem. What I did is directly put dict value to label text rather than passing from NSString. Taking it into string will give me value like 您好。
Here is what i've done.
cell.lblWord.text = [NSString stringWithFormat:#"Word: %#",[[dic objectForKey:#"cat"]objectForKey:#"chart"]];
It's strange but true, tried before but wasn't working.

I am trying to make the EA look for a certain value in a string and if that value exists in the string then remove it.
I tried doing it using the StringReplace() but i noticed it only returns the number of replacements and didnt actually returned the updated string:
string v5="- .82523";
string temp2 = v5;
temp2= StringReplace(temp2," ","");
Print(v5,temp2);
in the above code there is a white space between "-" and ".82523" and i am trying to remove that white space.
so the string is - .82523 and i am trying to get -.82523 , which function can be used for this ?
initially i thought i could do it by using the StringReplace() function , but seems like it only returns the Number of replacements that had happened and not the updated string.
Thanks in Advance
You are using the StringReplace() function incorrectly. Try the following code (from your example).
string v5="- .82523";
string temp2 = v5;
StringReplace(temp2," ","");
Print("<",v5,"> <",temp2,">");
I am facing the following issue:
In my app, the user can enter special characters (like emojis) in a textfield also. So, while sending this entered text to server in request body, I am converting it using the following code:
func emojiToUTF8()->String
{
let data = self.data(using: .nonLossyASCII, allowLossyConversion: true)
let emoji = String.init(data: data!, encoding: .utf8)
return emoji ?? self
}
For instance, if I enter the text "☺️", it gets converted into "\u263a\ufe0f" using the above method. Things are fine till here.
The problem occurs when I add this to a dictionary for sending it as a request parameter to the server. Code i'm using:
var parameters = [String:String]()
parameters["feedback"] = feedBackTxt
print("Parameters:",parameters) /// output: ["feedback": "\\u263a\\ufe0f"]
So, the problem here is that an extra slash is getting appended before each slash due to char escaping. I checked the created dictionary value as well. It shows double slash there also. How do I avoid this? Why is this happening when I am simply creating a dictionary with a string? This is causing issue at server end.
I have tried a couple of things, but none of them seem to work.
Your problem is that you're double-encoding.
You're taking a string, converting it to ASCII, then re-parsing it as UTF8 and then encoding that (probably) as JSON, which is UTF8. In the process, the backslashes are being escaped by your second encoder.
The best solution to this is to rework your server to accept UTF8. However, if you can't do that, you need to ensure you encode this string just one time, in ASCII.
In short, you should get rid of emojiToUTF8 and ensure that your parameters processor encodes the way your server requires (which apparently is ASCII and not UTF8).
I am trying to decode a string which is in UTF-8 format, into normal human readable string and tried may codes available on SO. But non of these worked.
My demo UTF-8 String is :-
let demoString: String = "यॠपहलॠपहलॠà¤à¤¾à¤¹à¤¤à¤¯à¥ बहà¤à¥ बहà¤à¥ हालत"
Is there is anyway to decode this UTF-8 String in swift. Any help would be appricated.
let demoString: String = "यॠपहलॠपहलॠà¤à¤¾à¤¹à¤¤à¤¯à¥ बहà¤à¥ बहà¤à¥ हालत"
This defines a perfectly fine string containing some rather weird characters like "à", "¤" and so on. There is no decoding that can be done here. The first character is a "Latin Small Letter A With Grave", U+00E0 or C3A0 in UTF-8 format.
If you want a string with "Hindi" characters - I suppose you mean Devanagari, or Bengali, Gurmukhi, Gujarati etc. , type for example
let demoString: String = "ऄइउऋऌऍ"
NSSet *subFolders = [_account subscribedFolders];
NSLog(#"subFolders: %#",subFolders);
Output:
...
"[Gmail]/\U05d8\U05d9\U05d5\U05d8\U05d5\U05ea",
"[Gmail]/\U05d7\U05e9\U05d5\U05d1"
...
Is there any way I can show the above text in its original language (Hebrew) ?
Things I tried:
changing the debugger from LLDB to GDB - Didn't work
Checking under preferences -> Text Editing UTF-* is selected
Thanks
There is no issue with displaying unicode characters in the console, so I would assume it's the way the string is getting into the set in the first place.
I would suggest iterating over all the objects inside subFolders with something like:
for( id object in [subFolders allObjects] ) {
//Print out the name of the item explicitly
}
Even if this doesn't work, it at least lets you work with the strings directly. If it's still printing out:
"[Gmail]/\U05d8\U05d9\U05d5\U05d8\U05d5\U05ea"
It would look as if you're being sent escaped unicode characters, and I would suggest this: https://stackoverflow.com/a/7861345/352891 - this may work directly on NSSet's description
NSString* strOld=[NSString stringWithFormat:#"%#",responseObject];
NSLog(#"%#",[NSString
stringWithCString:[strOld cStringUsingEncoding:NSUTF8StringEncoding]
encoding:NSNonLossyASCIIStringEncoding]);
I have a string (from HTTP Header) and want to split it into a dictionary.
foo = \"bar\",baz=\"fooz\", beta= \"gamma\"
I ca not guarantee that the string is the same every time. Maybe there are spaces, maybe not, sometimes the double quotes are escaped, sometimes not.
So I found the solution in PHP with regular expressions. Unfortunately I can't convert it to work on iOS.
preg_match_all('#('.$key.')=(?:([\'"])([^\2]+?)\2|([^\s,]+))#', $input, $hits, PREG_SET_ORDER);
foreach ($hits as $hit) {
$data[hit[1]] = $hit[3] ? $hit[3] : $hit[4];
}
Can anybody help me converting this to Objective-C?
I met a guy which is kinda RegEx guru. He explained the whole stuff and I got the following (working!!!!) solution in RegEx.
This gives me strings like foo="bar":
(?<=[,\\s])((realm|qop|nonce|opaque)=(?:([\"'])([^\2]+?)\2|([^\\s,]+)))
I then use another RegEx to split it by key and value to create a dictionary.
