ios - Allocate NSInteger* -


I'm sure there is nothing clear to me, but I want to make an example of an NSInteger pointer in Objective-C. - (NSInteger *) getIntegerPointer {NSInteger refValue = 0; NSInteger * theReturn = & amp; RefValue; Return; }

When I call this function the return is zero, but is valid with the debugger within the function.

Any suggestions? I do not want to convert theReturn to NSInteger.

variable refValue is a local variable, which means that it is on the stack While the -getIntegerPointer method is being executed. As the method goes back, the variable will run (the stack will be closed), so this address is no longer worthwhile.

If you want to return a valid indicator, you will have to allocate memory to the point being talked about, like this: 

  - (NSITFor *) getIntegerPointer {NSInteger refValue = 0; NSInteger * theReturn = malloc (size (NSInteger)); * TheReturn = refValue; Return; }

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. To clarify - this will not be a method error because it is a linked list.

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...
