ios - Backward with custom string -


I used string arrays for emoticons like this:

NSArray * emoticons = Then display such a string in a UITextview:

P> <<< <<> <<< << >> <<> <<< strong> Previous or Delete button, if the last word is in emoticons, then I The entire emoticon string should be removed, not the last one character

Any thoughts?

Try it out, 

  NSString * string = self.textView. Text; __block NSString * deleteWord = Zero; __bloc NSRange Range Overworld; [String EnumettsstringsResources: NSMKernage (0, Self TextView.SlectedRange.Lichn + Self Textviewview.CallectedRangleLayment) Option: NSSSringNewationByWords | Using NSStringEnumerationBlock: ^ (NSString * substring, NSRange subrange, NSR enclosed range, BOOL * stop) {deleteWord = substring; Range forward = enclosed range; * Stop = yes; }]; If ([Objects included in emoticons: deleteWord]) {string = [string stringBeerPlaceholdingCountry: CategoryForm string with: @ ""]; Self.textView.text = string; Self.textView.selectedRange = NSMakeRange (rangeOfWord.location, 0); }

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...
