ios - How to use correctly segue with a Tab Bar Controller? -


my application use different master detail, consist in initial viewcontroller tableview, when user click add button in navigation controller need send object using follow function:

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     if ([[segue identifier] isequaltostring:@"adddgv"]) {         nsindexpath *indexpath = [self.tableview indexpathforselectedrow];         nsmanagedobject *object = [[self fetchedresultscontroller] objectatindexpath:indexpath];         [[segue destinationviewcontroller] setdetailview:object];     } }

the code works fine when destination viewcontroller, application designed have tabbarcontroller instead viewcontroller. tabbar have 2 tabs, each 1 different navigation controller, , first 1 target identifier "adddgv". created .m/.h files , associated class in storyboard, , set instance variable "detailview" id.

@property (strong, nonatomic) id detailitem;

the problem compiler don't know variable, because command [segue destinationviewcontroller] contains view controller contents should displayed @ end of segue. end of segue tabbarcontroller, function doesn't work.

someone knows how fix it???

typecast output of 

[segue destinationviewcontroller]

as follows

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     if ([[segue identifier] isequaltostring:@"adddgv"]) {         nsindexpath *indexpath = [self.tableview indexpathforselectedrow];         nsmanagedobject *object = [[self fetchedresultscontroller] objectatindexpath:indexpath];         [(yourdestinationviewcontroller *)[segue destinationviewcontroller] setdetailview:object];     } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
