i mixing c++ , objectc. in particular, i'm adding c++ class/struct variable object-c header, , if legit? for example, @interface myview : uiview { mycppclass cppvariable; } @property (nonatomic, assign) mycppclass cppvariable; @end and @ implementation file, @synthesize cppvariable; well. as described in this official document on objective-c++ , can have non-pointer c++ objects inside objective-c classes. correctly constructed , destructed, if use option -fobjc-call-cxx-cdtors in gcc / clang. the situation @sythesiz ing non-pointer c++ @property not clear, because documentation lacking. behavior depends on compiler used, discussed e.g. in this question . clang team trying implement right thing, don't think it's available now. so, stick using pointer c++ classes if want @synthesize . otherwise, implement own setter , getter.

i read events tutorial , not benefit in simple code this..method should used same way: class bulb { public delegate void handler(); public event handler glowing; ... glowing+=somemethod; private void turnon { glowing(); } private void somemethod { } } simply events allow others using code perform custom implementation want when event occurs (when bulb glowing). simply calling method won't tell anybody has happened. events basic element of event driven programming if program doesn't need tell event don't need implement such functionality. having such functionality has benefits. for example when using list class dont know when item got added (if @ point other code that) in observablecollection notifications when items added or removed. an event message sent object signal occurrence of action. action caused user interaction, such mouse click, or triggered other program logic.

in languages have dealt with, 1 called convenience method, means method small task gets done frequently, , therefore more convenient use said method. in objective-c definition hold true? or used describe class methods return prebuilt object? ex.

(note it's not constructor in c++/java/c# sense, it's object initializer/factory method, seems convention call "convenience constructors"). "convenience constructors" in obj c convention or pattern creating constructor/initializer/factory method class takes specific parameters. pattern has special conventions should follow (such autoreleasing new object within constructor), custom classes fit in built-in types. see page (a little way down) more info: http://macdevcenter.com/pub/a/mac/2001/07/27/cocoa.ht...

i suppose doesn't matter, i'm curious. if difference between dictionary , lookup 1 one-to-one , other one-to-many, wouldn't dictionary more specific/derived version of other? a lookup collection of key/value pairs key can repeated. dictionary collection of key/value pairs key cannot repeated. why couldn't idictionary implement ilookup? i suspect because intention different. ilookup<t,u> designed work collection of values. idictionary<t,u> intended work single value (that could, of course, collection). while could, of course, have idictionary<t,u> implementations implement via returning ienumerable<u> single value, confusing, if "u" collection (ie: list<int> ). in case, ilookup<t,u>.item return ienumerable<list<int>> , or should type of check ienumerable<t> value type, , "flatten" it? either way, it'd confusing, , add questionable value.
