cocos2d iphone - What's the difference between declaration of an int with int keyword or with @property (nonatomic, assign)? -


i want know difference between writing :

@interface monster : ccsprite  @property (nonatomic, assign) nsstring *life; @property (nonatomic, assign) int color;  - (id)initwithfile:(nsstring *)file hp:(int)life:(nsstring *)color;  @end

and :

@interface monster : ccsprite{     nsstring *life;     int color; } - (id)initwithfile:(nsstring *)file hp:(int)life:(nsstring *)color;  @end

thank in advance help.

short answer: when add property, class invoked can have access it. example

levelclass alloc , init monster class , has access property this

monster *monsteristance = [[monster alloc] init]; nslog(@" monster life = %@", monsteristance.life);

and once use @property @synthesize automatically generates set , get code.

self.life = @"text";

is equal to

[self setlife: @"text"];

long answer: check out when-to-use-properties-in-objective-c , why-would-you-use-an-ivar

and should read this tutorial ray wenderlich site explain lot arc / property etc

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
