NSString *col1 = [aBook.name stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#" \n\t"]];
NSLog(#"column1: %#", col1); //output:- ABC+Company
This is my xml data output.
It comes with '+' mark. How can i decode this?
Could you please help me?
You mean get the parts that are seperated by the '+' sign? You can do that with:
NSArray *stringArray = [col1 componentsSeparatedByString:#"+"];
[stringArray objectAtIndex:0]; //ABC
[stringArray objectAtIndex:1]; //Company
If you want to remove/replace the '+' sign you can do this:
NSString* string = [col1 stringByReplacingOccurrencesOfString:#"+" withString:#""]; //last string can be empty or have a string value
Hope this helped you!
You can also replace the plus signs with spaces, if that’s what you’re after:
NSString *name = [col1 stringByReplacingOccurrencesOfString:#"+" withString:#" "];

This is my string.
NSString *str=#"A & B";
now i am converting it to NSUTF8StringEncoding.
str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"str: %#", str);
space is replaced with %20 but & is not replaced with %26.
nslog show
str: A%20&%20B
This is also not working
NSString *str=#"(A) & (B)";
str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"str: %#", str);
nslog show
str: (A)%20&%20(B)
I need this because i have to pass this as parameter value in webservice.
Anybody have idea for this. Please help me for this issue. Nice answer will be appreciated
You can use CFURLCreateStringByAddingPercentEscapes() to do that:
NSString *string = ...;
NSString *encodedString = CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, NULL, CFSTR("!*'();:#&=+$,/?%#[]"), kCFStringEncodingUTF8));
I am concatenating two string using following way I want space between Added Content To My Learning And the second String any idea how to give space thanks
NSString *firstString =#"Added Contnet To My Learning";
NSString *secondString = appDelegate.activity_Description;
appDelegate.activity_Description = [firstString stringByAppendingString:secondString];
You can do it like this.
NSString *firstString =#"Added Contnet To My Learning";
NSString *secondString = appDelegate.activity_Description;
appDelegate.activity_Description = [NSString stringWithFormat:#"%# %#", firstString, secondString];
Did you try?
NSString *firstString =#"Added Contnet To My Learning ";
// a space after the first string
Here is all way you can do with string
//1st Way
NSString *finalString = [NSString stringWithFormat:#"%# %#",firstString,secondString];
//2nd Way
NSString *finalString = [firstString stringByAppendingFormat:#" %#",secondString];
//3rd way
NSArray *ary= [NSArray arrayWithObjects:firstString,secondString, nil];
NSString *finalString= [ary componentsJoinedByString:#" "];

I have a string which gives the Date (below)
NSString*str1=[objDict objectForKey:#"date"];
NSLog(#" str values2%#",str1); --> 04-Jan-13
Now Problem is I need to Trim the"-13" from here .I know about NSDateFormatter to format date.but I can't do that here.I need to trim that
For that I am using:-
NSCharacterSet *charc=[NSCharacterSet characterSetWithCharactersInString:#"-13"];
[str1 stringByTrimmingCharactersInSet:charc];
But this does not work.this does not trim...how to do that..help
Not sure why not use an NSDateFormatter but here's a very specific way to approach this (very bad coding practice in my opinion):
NSString *theDate = str1;
NSArray *components = [theDate componentsSeparatedByString:#"-"];
NSString *trimmedDate = [NSString stringWithFormat:#"%#-%#",[components objectAtIndex:0],[components objectAtIndex:1]];
But this does not work.this does not trim...
It does trim, but since NSString is immutable, the trimmed string is thrown away, because you do not assign it to anything.
This would work (but do not do it like that!)
str1 = [str1 stringByTrimmingCharactersInSet:charc];
What you do is not trimming, it's taking a substring. NSString provides a much better method for that:
str1 = [str1 substringToIndex:6]; // Take the initial 6 characters
Something like this:
NSString *trimmed = [textStr stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
or this:
NSString *trimmed = [textStr stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#"-13"];
what you have done is correct. Only thing is stringByTrimmingCharactersInSet returns NSString. So you need to assign this value to NSString, like
str1 = [str1 stringByTrimmingCharactersInSet:charc];
if you're sure you have your string always formatted like "NN-CCC-NN" you can just trim the first 6 chars:
NSString* stringToTrim = #"04-Jan-13";
NSString* trimmedString = [stringToTrim substringToIndex:6];
NSLog(#"trimmedString: %#", trimmedString); // -> trimmedString: 04-Jan
I have a string say "Allentown, pa"
How to remove the white space in between , and pa using objective c?
This will remove all space from myString.
NSString *newString = [myString stringByReplacingOccurrencesOfString:#" " withString:#""];
Here is a proper and documented way of removing white spaces from your string.
whitespaceCharacterSet Apple Documentation for iOS says:
Returns a character set containing only the in-line whitespace characters space (U+0020) and tab (U+0009).
+ (id)whitespaceCharacterSet
Return Value
A character set containing only the in-line whitespace characters space (U+0020) and tab (U+0009).
Discussion
This set doesn’t contain the newline or carriage return characters.
Availability
Available in iOS 2.0 and later.
You can use this documented way:
[yourString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
Hope this helps you.
If you need any more help then please let me know on this.
Probably the solution in one of the answers in Collapse sequences of white space into a single character and trim string:
NSString *whitespaceString = #" String with whitespaces ";
NSString *trimmedString = [whitespaceString stringByReplacingOccurrencesOfString:#" " withString:#""];
If you want to white-space and new-line character as well then use "whitespaceAndNewlineCharacterSet" instead of "whitespaceCharacterSet"
NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet];
NSString *trimmedString = [temp.text stringByTrimmingCharactersInSet:whitespace];
NSLog(#"Value of the text field is %#",trimmedString);
myStr = [myStr stringByReplacingOccurrencesOfString:#" " withString:#""];
NSString *sample = #" string with whitespaces";
NSString *escapeWhiteSpaces = [sample stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
- (NSString *)removeWhitespaces {
return [[self componentsSeparatedByCharactersInSet:
[NSCharacterSet whitespaceCharacterSet]]
componentsJoinedByString:#""];
}
In my case NSString was added Zero Width Space(i i used some library). so solution worked for me.
NSMutableString *newString=[[newString stringByReplacingOccurrencesOfString:#"\u200B" withString:#""] mutableCopy];
#"\u200B" is Zero width space character value.
Here is the proper way to remove extra whitespaces from string which is coming in between.
NSString *yourString = #"Allentown, pa";
NSCharacterSet *whitespaces = [NSCharacterSet whitespaceCharacterSet];
NSPredicate *noEmptyStrings = [NSPredicate predicateWithFormat:#"SELF != ''"];
NSArray *parts = [yourString componentsSeparatedByCharactersInSet:whitespaces];
NSArray *filteredArray = [parts filteredArrayUsingPredicate:noEmptyStrings];
yourString = [filteredArray componentsJoinedByString:#" "];
you can use remove function to remove any substring from the string
- (NSString*)remove:(NSString*)textToRemove fromString:(NSString*)input {
return [input stringByReplacingOccurrencesOfString:textToRemove withString:#""];
}
I have tried all the solutions here, none of them could remove the whitespace generated by the Chinese PinYin Input method.
After some debugging, I found this working:
NSString *newString = [myString stringByReplacingOccurrencesOfString:#"\342\200\206" withString:#""];
I have googled what the '\342\200\206' is, but failed.
Whatever, it works for me.
Hi there is the swift version of the solution with extension :
extension String{
func deleteSpaces() -> String{
return self.stringByReplacingOccurrencesOfString(" ", withString: "")
}
}
And Just call
(yourString as! String).deleteSpaces()
Swift 3:
var word: String = "Hello world"
let removeWhiteSpace = word.stringByRemovingWhitespaces
word = "Helloworld"
Let's assume I have the string
NSString* myString = #"Hello,";
How can I remove the comma without leaving a space? I have tried:
NSString* newString = [myString stringByReplacingOccurrencesOfString:#"," withString:#""];
and
NSString* newString = [myString stringByTrimmingCharactersInSet:[NSCharacterSet punctuationCharacterSet]];
But both are leaving spaces.
I just ran the following as a test
NSString * myString = #"Hello,";
NSString * newString = [myString stringByReplacingOccurrencesOfString:#"," withString:#""];
NSLog(#"%#xx",newString);
And I get 2010-04-05 18:51:18.885 TestString[6823:a0f] Helloxx as output. There is no space left.
NSString *newString = [myString substringToIndex:5];
That will ensure that there are only 5 characters in the string, but beware that this will also throw an exception if there are not at least 5 characters in the string to begin with. How are you handling this string? Is it being displayed to the user? Is it being written to a file? The code that you posted does not reproduce the error, so perhaps you should post the code that you are having a problem with.
the other way u can use.. by stringByReplacingCharactersInRange
token = [token stringByReplacingCharactersInRange:NSMakeRange(i, 1) withString:#"*"];
"token"is your want to replace the NSString and "i" is you want to change NSString by "*"
