NSString tokenize in Objective-C

I need get all the words of a UITextView of individual form.
In an array for example.
Simple.. Just use this if you have one space between two words:
NSArray *words = [textview.text componentsSeparatedByString:#" "];
OR if there is the possibility of multiple spaces between words:
NSArray *words = [textview.text componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]

String replacement in Objective-C

I have a NSString:
NSString *string1 = #"http://example.com/this-is-an-example-post"
By removing a range of characteres I have substringed it to:
NSString *string2 = #"this-is-an-example-post"
But I am struggling to get it into the form of:
NSString *string3 = #"this is an example post"
Any help? Much appreciated.
For example this way
string3 = [string2 stringByReplacingOccurrencesOfString:#"-" withString:#" "];

Is there a simple way to split a NSString into an array of characters?
(4 answers)

I am trying to get each letter of an NSString using this line of code:
NSArray *array = [string componentsSeparatedByString:#""];
//string is equal to Jake
NSLog(#"Array Count:%d",[array count]);
I am expecting to get each letter of the word "Jake" but instead I am getting the whole word. Why?
From Apple's Doc about this method
NSString *list = #"Norman, Stanley, Fletcher";
NSArray *listItems = [list componentsSeparatedByString:#", "];
produces an array { #"Norman", #"Stanley", #"Fletcher" }.
So empty separator will not separate each character of string, this
method doesn't work this way.

How to convert NSString to NSArray with characters one by one in Objective-C
The idea of separating a string by nothing doesn't logically make sense, it is like trying to divide by zero.
But to answer the question:
NSMutableArray *stringComponents = [NSMutableArray arrayWithCapacity:[string length]];
for (int i = 0; i < [string length]; i++) {
NSString *character = [NSString stringWithFormat:#"%c", [string characterAtIndex:i]];
[stringComponents addObject:character];
}`

How to convert elements of NSMutableArray to NSString
(3 answers)
Closed 9 years ago.
I am trying to convert (or copy?) a NSMutableArray into a NSString. I guess my problem is that I don't really understand the structure of a NSString. In my limited knowledge, a string could look like this: in iphone
Try this code:-
NSString *string = [array componentsJoinedByString:#","];
take the NSMutableString and append every array string into your string
like
string = [string appendString:[NSString stringWithFormat:"%#", [array objectAtIndex:i]]];
