objective c - How to edit elements in plist file -


i have settings.plist , want edit values in file.

my function edit/writing is:

- (void) setparamwithname: (nsstring*) name withvalue: (nsstring*) value {  // paths root direcory nsarray *paths = nssearchpathfordirectoriesindomains (nsdocumentdirectory, nsuserdomainmask, yes); // documents path nsstring *documentspath = [paths objectatindex:0]; // path plist file nsstring *plistpath = [documentspath stringbyappendingpathcomponent:@"settings.plist"];  // check see if data.plist exists in documents if (![[nsfilemanager defaultmanager] fileexistsatpath:plistpath]) {     // if not in documents, property list main bundle     plistpath = [[nsbundle mainbundle] pathforresource:@"settings" oftype:@"plist"]; }  // read property list memory nsdata object nsdata *plistxml = [[nsfilemanager defaultmanager] contentsatpath:plistpath]; nsstring *errordesc = nil; nspropertylistformat format; // convert static property list dictionary object nsdictionary *temp = (nsdictionary *)[nspropertylistserialization propertylistfromdata:plistxml mutabilityoption:nspropertylistmutablecontainersandleaves format:&format errordescription:&errordesc]; if (!temp) {     nslog(@"error reading plist: %@, format: %d", errordesc, format); }  // checking if element exists, if yes overwriting  // if element not exists adding new element   [temp writetofile:plistpath atomically:yes]; 

}

this function read , write (with te same values) settings.plist.

i not have idea (my knowledge objective-c not enough) how add new element or edit existing element. can mi issue?

i think it's easier think.

once got path of file read nsdictionary. make mutable copy of dictionary mutablecopy , nsmutabledictionary. edit mutable dictionary (add s.th., remove s.th., edit s.th. , on).

now you're done can write old path did temp.

your main problem you're not working mutable version of dicitionary. it'd make life easier.
