objective c - (UIApplication *) Why is there a space before the asterisk? -

- 

-(void)applicationdidfinishlaunching:(uiapplication *) app {

after uiapplication why there space before asterisk?

this characteristic c code, i'm new objective-c forgive me if isn't proper objective c syntax. answer question. answers being style correct regard parameter such given in question. issue when declaring multiple variables on single line in c or c++ (this part i'm not sure if obj-c supports this).

int* i;

and

int *i;

are equivalent; when dealing multiple declarations

int* i, j;

is not same as

int *i, *j;

the * applied variable , not int, require * on each variable wish make pointer.

so purpose of having space after class name stylistic nod that.
