Property initializing in some function

[sam256]

If we initialize class property, created using

@property (nonatomic, retain) NSArray *prop

in the body of function

(void)init

in this way

prop = [NSArray arrayWithObjects:@"1", @"2", nil]

where will be a mistake in this code. What consequences in working program it will have and in what time moment, in what function it will happen?
