hello,
regarding finding out if an object instance is a particular type of
class or not
which should be used out of the following three?:
if( [anObject isMemberOfClass:[AClass class]] ) {
...
if( [anObject class] == [AClass self] ) {
...
if( [[anObject className] isEqualToString:@"AClass"] ) {
...
i suppose the last one is only necessary if you're dealing with class
names in strings, otherwise not necessary. i'm currently using
[anObject class] == [AClass self] but am wondering if it's OK?
thanks, ben
