IOS struct array, iOS struct Array

IOS struct array, iOS struct Array

In ios development, we often use struct, but xcode prompts a yellow warning when using struct arrays.

BMKMapPoint * points = new BMKMapPoint [pointCount];

BMKMapPoint is a struct. I dynamically declare a struct array.

Delete [] points;

Releases a struct array.

When writing a function to return a struct Array

+ (CLLocationCoordinate2D *) arrayTransformCoordinate :( NSArray *) array {CLLocationCoordinate2D coors [60]; int I = 0; for (NSDictionary * dic in array) {coors [I]. latitude = (NSNumber *) ([dic objectForKey: @ "latitude"]). doubleValue; coors [I]. longpolling = (NSNumber *) ([dic objectForKey: @ "longpolling"]). doubleValue; I ++;} return coors ;}

We can remove the yellow warning by changing the. m suffix to. mm.

This means that the compiler will use objective-c ++ to compile the file.
