Declaration

Discussion

For example, this code excerpt writes “here be dragons” to the console:

NSArray *pathArray = [NSArray arrayWithObjects:@"here", @"be", @"dragons", nil];
NSLog(@"%@",[pathArray componentsJoinedByString:@" "]);

Special Considerations

Each element in the array must handle description.
