objective c - casting to (id<protocol>) to guarantee a property is there -

-

if have number of classes like

@property (nonatomic, retain) nsstring* mystring;

and want access property in object 1 of these classes (but don't know type id), "request member 'mystring' in not structure or union" error.

so if each of these classes conforms :

@protocol myprotocol <nsobject>  @required  @property (nonatomic, retain) nsstring* mystring;  @end

then cast property:

(id<myprotocol>)anobject.mystring

why doesn't work? still same error.

in case prefer messages-sending notation on dot-notation, shows clearly, when cast happen:

these lines equal:

[(id<myprotocol>)anobject mystring] ((id<myprotocol>)anobject).mystring

and these are:

(id<myprotocol>)[anobject mystring] (id<myprotocol>)anobject.mystring

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
