in xcode-->organizer-->crashes, after locating code, thatcrash code use in uiviewcontroller category

- (void)showloadinghud { if(!self.view) {     return; } mbprogresshud *hud = [mbprogresshud showhudaddedto:self.view animated:yes]; hud.removefromsuperviewonhide = yes; hud.mode = mbprogresshudmodeindeterminate; } - (void)hidehud { if(!self.view) {     return; } [mbprogresshud hideallhudsforview:self.view animated:no]; }

can me?

my way use:

@property (strong, nonatomic) mbprogresshud *hud;

and then

#pragma mark - datamanager - - (void)getdata {  if (![self.hud ishidden]) {     [self.hud hideanimated:yes]; } self.hud = [mbprogresshud showhudaddedto:self.view animated:yes];  [xxxdatamanager xxxwithrequestmodel:self.xxxrequestmodel completion:^(bool success, id  _nullable result, nserror * _nullable error) {      [self.hud hideanimated:yes];      if (success) {         ...     }     else {         ...     } }];}

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...

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
