How to convert NSString to UTF8Encode ?
My NSLog print the same result as input string
NSString* username =#"MYUSERNAME";
username=[username stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString* Password =#"MYUSERNAMEPASS";
Password=[Password stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"username=%#",username);
NSLog(#"Password=%#",Password);
You need to use stringByAddingPercentEscapesUsingEncoding instead of stringByReplacingPercentEscapesUsingEncoding.
NSString *encodeUserName = [username stringByAddingPercentEscapesUsingEncoding:NSUTF32StringEncoding];
Also stringByAddingPercentEscapesUsingEncoding is deprecated so batter to use stringByAddingPercentEncodingWithAllowedCharacters like this
NSString *encodeUserName = [username stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet URLQueryAllowedCharacterSet]];

I have an NSString that internally uses UTF16 encoding. I want to covert it to use UTF32 , so that
😄 or q both take single index. Currenty 😄 takes 2.
How to do this ?. Even if I can convert to some other type from NSString it will work. Bottom line is to have 😄 or q take equal number of indexes in an array.
Did you try :
NSData *data = [string dataUsingEncoding:NSUTF32StringEncoding];
NSString *convertedString = [[NSString alloc] initWithData:data encoding:NSUTF32StringEncoding];
Have you tried [[NSString alloc]initWithData:encoding:]?
Example would be:
NSData *data = [sourceStr dataUsingEncoding:NSUTF16StringEncoding];
Create your NSUTF32StringEncoded string from the data above
NSString *encodedStr = [[NSString alloc]initWithData:data encoding:NSUTF32StringEncoding];

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:#" "];
