I've seen some answers but those didn't expand enough and I think they were before ARC was introduced.
So if I have two NSSstring can I set
string1 =string2;
or
NSString * a1=@"String";
al=@"Lead";
without causing memory leaks or other problems?
Edit: What about view controller or delegate properties set to (copy, nonatomic)?
Edit2: It should be NSString *al=@"String". I hope this doesn't change the idea that it doesn't leak.
neither would leak in ARC.
however, you might want to be aware that you are dealing with a reference in this case -- no implicit copy is performed (unless you use a copy or copy-qualified property).
for
NSString
s? yes,copy
should be the default forNSString
s.nonatomic
should be the default for everything. of course, there are exceptions to this -- when you might deviate from the defaults.
