My Question is regarding special Character in NSString.
Actual name:- Yusuf Doğan
Retrieve name= Yusuf Do\u011fan
My Actual fb friend name is Yusuf Doğan (Check Special "g with ~ cap").
I take it as NSdata and then converter it in to nsstring.
NSString *stringResponse = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
But the nsstring shows it as
"Yusuf Do\u011fan"
Similar cause with the following.
Ricsi Zoványi as Ricsi Zov\u00e1nyi
Pero Perić as Pero Peri\u0107
Any Solution.
Thanks in advance.
You can try this:
NSString *source = [NSString stringWithString:_username];
[_username release];
NSMutableString *result = [[NSMutableString alloc] init];
NSScanner *scanner = [NSScanner scannerWithString:source];
[scanner setCharactersToBeSkipped:nil];
while (![scanner isAtEnd]) {
NSString *chunk;
// Scan up to the Unicode marker
[scanner scanUpToString:#"\\u" intoString:&chunk];
// Append the chunk read
[result appendString:chunk];
// Skip the Unicode marker
if ([scanner scanString:#"\\u" intoString:nil]) {
// Read the Unicode value (assume they are hexa and four)
unsigned int value;
NSRange range = NSMakeRange([scanner scanLocation], 4);
NSString *code = [source substringWithRange:range];
[[NSScanner scannerWithString:code] scanHexInt:&value];
unichar c = (unichar) value;
// Append the character
[result appendFormat:#"%C", c];
// Move the scanner past the Unicode value
[scanner scanString:code intoString:nil];
}
}
_username = [[NSString stringWithFormat:#"%#",result] retain];
[result release];
}
Instead of "NSUTF8StringEncoding" use "NSUTF16StringEncoding". I think this may solve your issue.

I have an int value which I obtained from the character 爸, which is 29240. I can convert this number to hex, but I have no clue how to write the chinese character out in an NSString with only the int 29240.
Basically, what I did was:
NSString * s = #"爸";
int a = [s characterAtIndex:0];
NSLog(#"%d", a);
What it gave as output was 29240.
However, I don't know how to create an NSString that just contains 爸 from only the int 29240.
I converted 29240 into binary which gave me 7238, but I can't seem to create a method which allows me to input any integer and NSLog the corresponding character.
I can hard code it in, so that I have
char cString[] = "\u7238";
NSData *data = [NSData dataWithBytes:cString length:strlen(cString)];
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"result string: %#", string);
But I'm not sure how to do it with any int.
Thanks to anyone who can help me!
To create a string from one (or more) Unicode characters use initWithCharacters:
unichar c = 29240;
NSString *string = [[NSString alloc] initWithCharacters:&c length:1];
NSString uses UTF-16 characters internally, so
this works for all characters in the "Basic Multilingual Plane", i.e. all characters up to U+FFFF. The following code works for arbitrary characters:
uint32_t ch = 0x1F60E;
ch = OSSwapHostToLittleInt32(ch); // To make it byte-order safe
NSString *s1 = [[NSString alloc] initWithBytes:&ch length:4 encoding:NSUTF32LittleEndianStringEncoding];
NSLog(#"%#", s1);
// Output: 😎
Try out this code snippet to get you started in the right direction:
NSString *s = #"0123456789";
for (int i = 0; i < [s length]; i++) {
NSLog(#"Value: %d", [s characterAtIndex:i]);
}
Just pass in the character as an integer:
unichar decimal = 12298;
NSString *charStr = [NSString stringWithFormat:#"%C", decimal];
I need to get substring CODE's value (X2.31) from string
NSString *str = #"SHMU=\"\" CODE=\"X2.31\" XTN=\";
How could I get that particular substring?
Try the below one
NSString *str = #"SHMU=\"\" CODE=\"X2.31\" XTN=\"";
NSRange range = [str rangeOfString:#"CODE="];
NSString *substring = [[str substringFromIndex:NSMaxRange(range)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSArray *str1 = [substring componentsSeparatedByString:#" "];
NSLog(#"the sub %#",[[str1 objectAtIndex:0] stringByTrimmingCharactersInSet[NSCharacterSet whitespaceCharacterSet]]);
And by string was "X2.31"
NSString *strOrg = [NSString stringWithFormat:#"%#",#"SHMU=\"\" CODE=\"X2.31\" XTN=\""] ;
NSString *strLeft = [NSString stringWithFormat:#"%#",#"SHMU=\"\" CODE=\""] ;
NSString *strRight = [NSString stringWithFormat:#"%#",#"\" XTN=\""] ;
NSLog(#"%#", [self getDataBetweenString:strOrg LeftString:strLeft RightString:strRight LeftOffset:13]);
- (NSString *)getDataBetweenString:(NSString *)orgString LeftString:(NSString *)leftString RightString:(NSString *)rightString LeftOffset:(NSInteger)leftPos;
{
NSInteger left, right;
NSString *foundData;
NSScanner *scanner=[NSScanner scannerWithString:orgString];
[scanner scanUpToString:leftString intoString: nil];
left = [scanner scanLocation];
[scanner setScanLocation:left + leftPos];
[scanner scanUpToString:rightString intoString: nil];
right = [scanner scanLocation] + 1;
left += leftPos;
foundData = [orgString substringWithRange: NSMakeRange(left, (right - left) - 1)]; return foundData;
}
This is only specific to the str you posted.
Your number must be followed by First X.
float f=[[str componentsSeparatedByString:#"X"][1] floatValue];
How do I get string using NSScanner from a string which contains string as well as numbers too?
i.e. 001234852ACDSB
The result should be 001234852 and ACDSB
I am able to get numbers from the string using NSScanner and characters by using stringByReplacingOccurrencesOfString but I want to know, is that possible to get string from with the use of NSScanner or any other built in methods?
I would like to know the Regex for the same.
If you can guarantee that the string always consists of numbers followed by letters, then you could do the following with NSScanner:
NSScanner *scanner = [NSScanner scannerWithString:#"001234852ACDSB"];
NSString *theNumbers = nil;
[scanner scanCharactersFromSet:[NSCharacterSet decimalDigitCharacterSet]
intoString:&theNumbers];
NSString *theLetters = nil;
[scanner scanCharactersFromSet:[NSCharacterSet letterCharacterSet]
intoString:&theLetters];
A regular expression capturing the same things would look like this:
([0-9]+)([a-zA-Z]+)
Finally after google for the same and go through some information from net, I reached to my destination. With this I'm posting the code, this may help many who are facing the same problem as I have.
NSString *str = #"001234852ACDSB";
NSScanner *scanner = [NSScanner scannerWithString:str];
// set it to skip non-numeric characters
[scanner setCharactersToBeSkipped:[[NSCharacterSet decimalDigitCharacterSet] invertedSet]];
int i;
while ([scanner scanInt:&i])
{
NSLog(#"Found int: %d",i); //001234852
}
// reset the scanner to skip numeric characters
[scanner setScanLocation:0];
[scanner setCharactersToBeSkipped:[NSCharacterSet decimalDigitCharacterSet]];
NSString *resultString;
while ([scanner scanUpToCharactersFromSet:[NSCharacterSet decimalDigitCharacterSet] intoString:&resultString])
{
NSLog(#"Found string: %#",resultString); //ACDSB
}
You don't have to use a scanner to do it.
NSString *mixedString = #"01223abcdsadf";
NSString *numbers = [[mixedString componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:#"0123456789"] invertedSet]] componentsJoinedByString:#""];
NSString *characters = [[mixedString componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:#"abcdefghijklmnouprstuwvxyz"] invertedSet]] componentsJoinedByString:#""];
For other possible solution view this question Remove all but numbers from NSString
I have an NSDictionary object that contains my data. I am passing in an array of key names and a display format for a string representation of my data.
[self displayMyDataWithTheseKeys:myKeyArray inThisFormat:myFormat];
where, for example,
myKeyArray = [NSArray arrayWithObjects: #"Key1", #"Key2", nil];
myFormat = [NSString stringWithString: #"%# to the %# degree"];
However, myFormat may change and the number of keys in the array may vary as well.
If the number of elements in the array was always 2, this would be trivial. However, how can I handle a variable number of elements?
There isn't really a built-in method for this, but it's relatively easy to parse format strings with NSScanner. Here's a simple example, it only handles %# format specifiers, but as all elements in an NSArray are objects and not primitive types anyway, it shouldn't matter:
NSArray *myKeyArray = [NSArray arrayWithObjects: #"Key1", #"Key2", nil];
NSString *myFormat = [NSString stringWithString: #"%# to the %# degree"];
NSMutableString *result = [NSMutableString string];
NSScanner *scanner = [NSScanner scannerWithString:myFormat];
[scanner setCharactersToBeSkipped:[NSCharacterSet illegalCharacterSet]];
int i = 0;
while (![scanner isAtEnd]) {
BOOL scanned = [scanner scanString:#"%#" intoString:NULL];
if (scanned) {
if (i < [myKeyArray count]) {
[result appendString:[myKeyArray objectAtIndex:i]];
i++;
} else {
//Handle error: Number of format specifiers doesn't
//match number of keys in array...
}
}
NSString *chunk = nil;
[scanner scanUpToString:#"%#" intoString:&chunk];
if (chunk) {
[result appendString:chunk];
}
}
Use: stringByAppendingString
Here's an example on how to use it:
NSString *someString = #"String";
someString = [someString stringByAppendingString:[NSString stringWithFormat:#"%#",variable1]];
someString = [someString stringByAppendingString:[NSString stringWithFormat:#"%#",variable2]];
someString = [someString stringByAppendingString:[NSString stringWithFormat:#"%#",variable3]];
...and so on
If you have an array of keys which you want to put in a string:
NSString *string = #"And the keys are:\n";
for(int i = 0; i < [array count]; i++)
{
NSString *thisKey = (NSString *)[array objectAtIndex:i];
string = [string stringByAppendingString:[NSString stringWithFormat:#"Key number %d is %#",i,thisKey]];
}
my string is k= /Users/applefan/Library/Application Support/iPhone Simulator/3.1.3/Applications/422B3239-F521-4985-89FE-EC778C57C0AB/Documents/1.sql
now how to get 1 from 1.sql
i did somethins like this
NSScanner *scanner = [NSScanner scannerWithString:storePath];
[scanner scanUpToString:#".sql" intoString:&k] ;
NSLog(#"test is %#",k);
i did this also
unsigned int intValue;
while([scanner isAtEnd] == NO) {
[scanner scanHexInt:&intValue];
NSLog(#"HEX : %d", intValue);
**}
it gives me all the int value**
but i only want the numeric value after /Documents/
NSString *k = #"/Users/applefan/Library/Application Support/iPhone Simulator/3.1.3/Applications/422B3239-F521-4985-89FE-EC778C57C0AB/Documents/1.sql";
NSString *one = [[[[k componentsSeparatedByString:#"Documents/"] objectAtIndex:1]
componentsSeparatedByString:#".sql"] objectAtIndex:0];
NSLog(#"Is it one? %#", one);
