NSMutableArray:
*Creating an NSMutableArray
Creating an NSMutableArray
suggest changeNSMutableArray can be initialized as an empty array like this:
NSMutableArray *array = [[NSMutableArray alloc] init];
// or
NSMutableArray *array2 = @[].mutableCopy;
// or
NSMutableArray *array3 = [NSMutableArray array];NSMutableArray can be initialized with another array like this:
NSMutableArray *array4 = [[NSMutableArray alloc] initWithArray:anotherArray];
// or
NSMutableArray *array5 = anotherArray.mutableCopy;
Found a mistake? Have a question or improvement idea?
Let me know.
