Answer 1

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.
