Question

I have an NSArray with objects :

NSArray *array = [NSArray arrayWithObjects:@"Saturday",@"Sunday",@"Monday",@"tuesday",@"Wednesday",@"thursday",nil]; 

and some times like this :

array = [NSArray arrayWithObjects:@"Tuesday",@"Monday",nil];

I would like to have a string like this :

dinner : sunday, monday,tusday, wednesday, thurs...

or

dinner : tuesday, monday.

How i can i do this with stringWithFormat?

Answer 1

Use NSArray‘s componentsJoinedByString:.

NSArray *array = [NSArray arrayWithObjects:@"Saturday",@"Sunday",@"Monday",@"tuesday",@"Wednesday",@"thursday",nil];
NSString *string = [NSString stringWithFormat:@"dinner: %@", [array componentsJoinedByString:@", "]];
