ios - Objective C : Separate words in a string and join again -


This question is already an answer here Is: <6 answers

I have a string @ "DidNotTurnUp" . I want to write a function that takes this string as an input and output should be @ "not turned on" . What would be the best way to do this? How to separate words in a string based on capital letters? HELP appreciated.

Here is a class on NSString that will be what you want. 

  @implementation NSString (SeparateCapitalizedWords) - (NSString *) stringBySeparatingCapitalizedWords {Fixed NSRegularExpression * __regex; Static transmissions_access_one talk; Dispatch_once (& amp; oneToken, ^ {NSError * error = zero; __regex = [NSRegularExpression regularExpressionWithPattern: @ "[P \\ {uppercase letter}]" option: 0 error: & amp; error], if (error) {@ Throw error;}}); NSString * Result = [__regex stringByReplacingMatchesInString: Self Option: 0 Range: (NSRange) {1, self.length - 1} withTemplate: @ "$ 0"]; Return result; } @end

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
