ios - How to add a key and string in dictionary? -

-

my plist file:

   nsarray *documentpaths = nssearchpathfordirectoriesindomains(nscachesdirectory, nsuserdomainmask, yes);    nsstring *path = [[documentpaths lastobject] stringbyappendingpathcomponent:@"data.plist"];    dict = [nsdictionary dictionarywithcontentsoffile:path];

loop through array, adding annotations , calculate distance:

 ann = [dict objectforkey:@"blue"];  [resultarray addobject:@"blue"];    for(int = 0; < [ann count]; i++) {    nsstring *coordinates = [[ann objectatindex:i] objectforkey:@"coordinates"];   double reallatitude = [[[coordinates componentsseparatedbystring:@","] objectatindex:1] doublevalue];  double reallongitude = [[[coordinates componentsseparatedbystring:@","] objectatindex:0] doublevalue];   myannotation *myannotation = [[myannotation alloc] init];  cllocationcoordinate2d thecoordinate;  thecoordinate.latitude = reallatitude;  thecoordinate.longitude = reallongitude;   myannotation.coordinate=cllocationcoordinate2dmake(reallatitude,reallongitude);  myannotation.title = [[ann objectatindex:i] objectforkey:@"name"];  myannotation.subtitle = [[ann objectatindex:i] objectforkey:@"address"];  myannotation.icon = [[ann objectatindex:0] objectforkey:@"icon"];   [mapview addannotation:myannotation];  [annotations addobject:myannotation];   cllocation *pinlocation = [[cllocation alloc]                                            initwithlatitude:reallatitude                                            longitude:reallongitude];   cllocation *userlocation = [[cllocation alloc]                                  initwithlatitude:mapview.userlocation.coordinate.latitude                                             longitude:mapview.userlocation.coordinate.longitude];   cllocationdistance distance = [pinlocation distancefromlocation:userlocation];   nslog(@"distance: %4.0f m.", distance);   }

my plist structure:

enter image description here

now need add dictionaries in "blue" array new key named "distance" string distance

you can write these lines inside for() loop :

nsstring *dist = [nsstring stringwithformat:@"%4.0f m.", distance]; nsmutabledictionary *indict = [[nsmutabledictionary alloc] init]; indict = [ann objectatindex:i]; [indict setvalue:dist forkey:@"distance"];

goodluck !!!

it can in xml or text format. how in general grep block of text in perl? <track type="ws"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>0</locationindex> <propertyindex>0</propertyindex> </range> </track> <track type="ps" id="1"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>1</locationindex> <propertyindex>1</propertyindex> </range> </track> i want grep type="ps" , till </range> . one solution open file, read line line , match block. open(fh, "file.txt"); foreach $line (<fh>) { if ($line =~ m/type="cc"(.*?)<\/range>/) { print $1; } } but there more optimal solution without reading file line l

Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
