# alloc

Returns a new instance of the receiving class.

## Declaration

```occ
+ (instancetype) alloc;
```

## Return Value

Return Value A new instance of the receiver.

## Discussion

Discussion This is an instance variable of the new instance that is initialized to a data structure describing the class; memory for all other instance variables is set to 0. You must use an init... method to complete the initialization process. For example: TheClass *newObject = [[TheClass alloc] init]; Do not override alloc to include initialization code. Instead, implement class-specific versions of init... methods. For historical reasons, alloc invokes allocWithZone:.
