Structure Array in iOS

We often use structs in iOS development, but when we use struct arrays, Xcode has a yellow warning hint.

Bmkmappoint *points = new Bmkmappoint[pointcount];

Bmkmappoint is a struct, I declare a struct array dynamically.

delete [] points;

Releases a struct array.

When you write a function that wants to return an array of structs

+ (CLLOCATIONCOORDINATE2D *) Arraytransformcoordinate: (Nsarray *) array{    cllocationcoordinate2d coors[60];    int i =0;    For (nsdictionary *dic in array) {        Coors[i].latitude = ((NSNumber *) ([dic objectforkey:@ "latitude"]). doublevalue;< C4/>coors[i].longitude = ((NSNumber *) ([dic objectforkey:@ "longitude"]). Doublevalue;        i++;    }    return Coors;}

We can do this to eliminate the yellow warning: change the. m suffix to. mm

This will do, meaning to tell the compiler to compile the file with objective-c++.
