我在将C数组声明为Objective-C属性时遇到麻烦(您知道@property和@synthesize,因此我可以使用点语法)...它只是3维int数组。
You can't -- arrays are not lvalues in C. You'll have to declare a pointer property instead and rely on code using the correct arraybounds, or instead use an NSArray
property.
Example:
@interface SomeClass
{
int width, height, depth;
int ***array;
}
- (void) initWithWidth:(int)width withHeight:(int)height withDepth:(int)depth;
- (void) dealloc;
@property(nonatomic, readonly) array;
@end
@implementation SomeClass
@synthesize array;
- (void) initWithWidth:(int)width withHeight:(int)height withDepth:(int)depth
{
self->width = width;
self->height = height;
self->depth = depth;
array = malloc(width * sizeof(int **));
for(int i = 0; i < width; i++)
{
array[i] = malloc(height * sizeof(int *));
for(int j = 0; j < height; j++)
array[i][j] = malloc(depth * sizeof(int));
}
}
- (void) dealloc
{
for(int i = 0; i < width; i++)
{
for(int j = 0; j < height; j++)
free(array[i][j]);
free(array[i]);
}
free(array);
}
@end
Then you can use the array
property as a 3-dimensional array.
