ios - Could [NSMutableArray array] return nil? -


for example in low memory conditions. i'm reading third party code , saw this

nsmutablearray *array = [nsmutablearray array];  if (array != nil) {      [array addobject:anobject]; }

i've never check after creating array way nor alloc+init i'm in doubt.

technically, could return nil.

the probability of such failure @ point incredibly unlikely. app crash or abort before nil returned. consider unlikely malloc returning null.

my implementations have used checked object creation years - cannot remember ever seeing [nsmutablearray array] return nil in time in development/testing.

note answer specific [nsmutablearray array], not any/every initializer/constructor in existence. [nsmutablearray array] 'consistent' class of initializer/constructor in regard because there no reason fail under normal circumstances.

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;} }
