These examples of string manipulation in iPhone apps<\/strong> were taken from the Internet and I don’ pretend on the authority rights for them. <\/p>\n

    \n
  1. Appending string to another string:<\/strong>
    \n
    \nNSString *myString = @\"This\";
    \nNSString *test = [myString stringByAppendingString:@\" is just a test\"];
    \n<\/code>\n<\/li>\n

    <\/br><\/p>\n

  2. Method with wide possibilities to format string and concatenate several strings:<\/strong>
    \n
    \n- (NSString*) concatenateString:(NSString*)stringA withString:(NSString*)stringB {
    \nNSString *finalString = [NSString stringWithFormat:@\"%@%@\", stringA, stringB]; return finalString; }
    \n<\/code>
    \n<\/br>
    \nThe advantage of this method is that it is simple to put text between the two strings (e.g. Put a “-” replace %@%@ by %@ – %@ and that will put a dash between stringA and stringB\n<\/li>\n

    <\/br><\/p>\n

  3. String Length:<\/strong>
    \n
    \n- (int) stringLength:(NSString*)string { return [string length]; \/\/Not sure for east-asian languages, but works fine usually }
    \n<\/code><\/li>\n

    <\/br><\/p>\n

  4. Remove text from string:<\/strong>
    \n
    \n- (NSString*)remove:(NSString*)textToRemove fromString:(NSString*)input { return [input stringByReplacingOccurrencesOfString:textToRemove withString:@\"\"]; }
    \n<\/code><\/li>\n

    <\/br><\/p>\n

  5. Uppercase \/ Lowercase \/ Titlecase:<\/strong>
    \n
    \n- (NSString*)uppercase:(NSString*)stringToUppercase { return [stringToUppercase upercaseString]; }<\/p>\n

    - (NSString*)lowercase:(NSString*)stringToLowercase { return [stringToUppercase lowercaseString]; }
    \n<\/code><\/li>\n

    <\/br><\/p>\n

  6. Find\/Replace:<\/strong>
    \n
    \n- (NSString*)findInString:(NSString*)string replaceWithString:(NSString*)stringToReplaceWith { return [input stringByReplacingOccurrencesOfString:string withString:stringToReplaceWith]; }
    \n<\/code>\n<\/li>\n

    <\/br><\/p>\n

  7. String comparison Case Sensitive<\/strong>:
    \n
    \nif ([category isEqualToString:@\"Some String\"])
    \n{
    \n doSomething = YES;
    \n}
    \n<\/code>
    \n<\/br>
    \nCase Insensitive: <\/strong>
    \n
    \nif (!([category compare:@\"Some String\" options:NSCaseInsensitiveSearch]))
    \n{
    \n doSomething = YES;
    \n}
    \n<\/code>\n<\/li>\n<\/ol>\n
