mapkit - Multiple pin drop on map in iphone aap -


i doing code multiple pin drop on mapview.

- (void)geocode {     nsarray *arrcityname = [nsarray arraywithobjects:@"baroda", @"surat", @"ahmedabad", @"rajkot", @"junagadh", @"mumbai", @"mehsana", @"veraval", @"surendranagar", @"gondal", nil];      cllocationcoordinate2d coordinate;     mkcoordinateregion region;     displaymap *ann = [[displaymap alloc] init];      [_mapview setmaptype:mkmaptypestandard];     [_mapview setzoomenabled:yes];     [_mapview setscrollenabled:yes];     [_mapview setdelegate:self];      (int = 0; < [arrcityname count]; i++)     {         coordinate = [self geocodeusingaddress:[arrcityname objectatindex:i]];          nslog(@"lat: %f --- long: %f --- city:--> %@",coordinate.latitude,coordinate.longitude,[arrcityname objectatindex:i]);          region.center.latitude = latitude;         region.center.longitude = longitude;         region.span.longitudedelta = 1.8;         region.span.latitudedelta = 1.8;          [_mapview setregion:region animated:yes];          ann.title = [arrcityname objectatindex:i];         ann.coordinate = region.center;         [_mapview addannotation:ann];     } }  - (cllocationcoordinate2d) geocodeusingaddress:(nsstring *)address {     latitude = 0, longitude = 0;     nsstring *esc_addr =  [address stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];     nsstring *req = [nsstring stringwithformat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr];     nsstring *result = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:req] encoding:nsutf8stringencoding error:null];     if (result) {         nsscanner *scanner = [nsscanner scannerwithstring:result];         if ([scanner scanuptostring:@"\"lat\" :" intostring:nil] && [scanner scanstring:@"\"lat\" :" intostring:nil]) {             [scanner scandouble:&latitude];             if ([scanner scanuptostring:@"\"lng\" :" intostring:nil] && [scanner scanstring:@"\"lng\" :" intostring:nil]) {                 [scanner scandouble:&longitude];             }         }     }     cllocationcoordinate2d center;     center.latitude = latitude;     center.longitude = longitude;     return center; }

here issue giving last pin drop. want multiple pin drop per array value.

i facing similar issue when tried add multiple pins. did : set global counter increase 1 on every annotation added i.e. on addannotaion. create function of loop :

coordinate = [self geocodeusingaddress:[arrcityname objectatindex:i]];      nslog(@"lat: %f --- long: %f --- city:--> %@",coordinate.latitude,coordinate.longitude,[arrcityname objectatindex:i]);      region.center.latitude = latitude;     region.center.longitude = longitude;     region.span.longitudedelta = 1.8;     region.span.latitudedelta = 1.8;      [_mapview setregion:region animated:yes];      ann.title = [arrcityname objectatindex:i];     ann.coordinate = region.center;     [_mapview addannotation:ann];

and call function till count reaches arrcityname's count

- (mkannotationview *)mapview:(mkmapview *)mapview viewforannotation:(id <mkannotation>)annotation { static nsstring *identifier = @"carlocation"; if ([annotation iskindofclass:[mapviewannotation class]]) {        static nsstring *annotationidentifier = @"annotationidentifier";     mkpinannotationview *pinview = (mkpinannotationview *)[mapview dequeuereusableannotationviewwithidentifier:annotationidentifier];     if (!pinview)     {         pinview = [[[mkpinannotationview alloc] initwithannotation:annotation reuseidentifier:annotationidentifier] autorelease];         pinview.canshowcallout = yes;         pinview.animatesdrop = yes;     }     else     {         pinview.annotation = annotation;     }      uiimageview *leftcalloutview = [[uiimageview alloc]                                     initwithimage:((mapviewannotation *)annotation).imagepin];     pinview.leftcalloutaccessoryview = leftcalloutview;     pinview.image = leftcalloutview.image;     [leftcalloutview release];     [self performselector:@selector(intermediate) withobject:nil afterdelay:1.05];       return pinview;  }

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
