core data - setFetchBatchSize Fetching all the rows in messages Table -


following code snippet.

nssortdescriptor *sortsequence = [[nssortdescriptor alloc]                                       initwithkey:@"date_added" ascending:yes];  nsarray *sortdescriptors =[nsarray arraywithobjects:sortsequence,nil];  [fetchrequest setfetchbatchsize:5]; [fetchrequest setsortdescriptors:sortdescriptors]; [nsfetchedresultscontroller deletecachewithname:@“chats”]; nsfetchedresultscontroller *thefetchedresultscontroller =[[nsfetchedresultscontroller alloc] initwithfetchrequest:fetchrequest managedobjectcontext: managedobjectcontext sectionnamekeypath:@"messagesectionkey" cachename:@"chats"];

in listing want implement load more functionality. want sort based on key date_added . messagesectionkey getter method in coredata class return yesterday,today etc based on date_added … after fetching instead of loading 5, loading rows in message table

i guess 5 objects should set fetch limit 5

[fetchrequest setfetchlimit:5];

to 20 records , pass in parameter value of numberofitems = 20, working inside function, idea , can make own function, guess should use fetchlimit 

-(void) getrecordsfor:(nsinteger) numberofrecords { ....   [fetchrequest setfetchlimit: numberofrecords];  [fetchrequest setsortdescriptors:sortdescriptors]; [nsfetchedresultscontroller deletecachewithname:@“chats”]; ... }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
