ios - Converting an array of ints to titlesForSegmentAtIndex -

i have custom segmented control can select multiple segments , saves selected indexes selected in array. want each int want titleforsegmentatindex , put titles array or string, struggling set correct loop.

here have right now:

nslog(@"%@", array); 

prints:

(     0,     1,     4 ) 

here array:

nsmutablearray *array = [nsmutablearray array]; [self.type.selectedsegmentindexes enumerateindexesusingblock:^(nsuinteger idx, bool *stop) {     [array addobject:@(idx)]; }]; 

and assume need use [segmentcontrol titleforsegmentatindex:int] dont know how incorporate loop.

you need create nsmutablearray , add titles in for ... in loop.

nsmutablearray *titles = [nsmutablearray array]; (nsnumber *index in array) {     [titles addobject:[segmentedcontrol titleforsegmentatindex:index.integervalue]]; } 

you can use plain old for loop, for ... in cleaner , faster.
