macOS [NOOB] Question about asterisk placement in Obj C

In not the order you asked:
CGRect is a structure, and that's a local instance. You can have pointers to structures on the heap or local instances, though in Foundation most struct *s are typedef'd to TypeRef (i.e. CGRectRef) so you don't have *s about when dealing with structures, to delineate from Objects.

NSString* blah
IBOutlet UITextfield *textField

These two just show a difference in style. I prefer that the * go with the varaible like the second example, for this reason:
in this case, if you put the * next to int, it might mislead one into thinking everything is an int *, instead of x being an int * and y,z, and a being ints.

(NSString *) blah
In this case, i would expect to see this in the signature of a class or object method. In this case, the types are always parenthesized. If you saw this in another context, that would be odd.

(NSString*) blah

could also be casting blah from another pointer type, such as NSObject, to an NSString pointer.

Good call, out of context it was hard to place.

An important thing to remember when programming in Objective-C (and most other languages) is that whitespace is meaningless. All you need to do is make sure that keywords are kept together. int and in t are different for instance.


are all exactly the same. I could write it as:


if I wanted and it would still be fine.
