ios - Error when performing batch update on UICollectionView -


I get this error every time I reload UICollectionview and I do not think this is an error indicator because the archive view should not be updated before this call 
  - (zero) load Gallery: (Zero (^) ()) Completed ({self indeminateAssetsWithCompletion: ^ (BOOL breakthrough, NSMutableArray * property) {if (success) {self.photos = [property volatile coop]; @ attempt {[self.collectionView PerformBatchUpdates: ^ {[self.collectionView reloaddata];} Closing: ^ (BOOL Finish) {complete ();}};} @chitch (NSE exp Exceptions) {} {} "}}};} - (zero) enumerate assets termination: (zero (^) (Bell's success, NSMUtABEL * Assets) * Lock complete {ALSATS Library * al = [[Self-class] Shared library; __block NSMutableArray * mutableAssets = [NSMutableArray new]; [Al-Enumerate Groups Waste Type: Use the Elassette Group L.Loc: ^ (ALSATT Group * Group, Ball * stop) {if (Group == Sh NY) {//self.groups = [Mutiv Group Copy]; If (period) {full ball (yes, mutuishet); }} And {{Group Set Assets Filler: [All Photos All Photos]]; [Group Enumerate Asset Block: ^ (ALSSset * result, NSUntengar index, BOL * stop) {if (result) {[MUSICASESET adobject: result]; }}]; }} FailureBlock: ^ (NSError * error) {ELog (@ "Failed to calculate clusters. Error:% @.", Error); Block (no, zero) to complete if (perfection block); }]; }   
 Error:  
  Dubai: failure to update batch Invalid update: Invalid number of items in section 1. After update (352), the number of items present in an existing section should be equal to the number of items in that section before the update (0), plus or less number removed from that segment (0 entered, 0 removed) Or the number of items transferred to that section from plus or minus of removed items (moved in 0, moved to 0). In the batch update block, you must insert, delete, reload, or move the cells.    
 
 
  
 Just look at the archive within the batch update block Reloading is incorrect because you are not including anything, and after updating batch, the new calculation of storage view items is higher than before. > Therefore, you should reload your collection view without batch updating or insert 352 items inside the block.  
  NSIndexSet * indexSet = [NSIndexSet indexSetWithIndexesInRange: NSMakeRange (0, self.photos.count)]; [Self.collectionView performBatchUpdates: ^ {{indexSet enumerateIndexesUsingBlock: ^ (NSUInteger idx, bool * stop) {[self.collectionView insertItemsAtIndexPaths: @ [[NSIndexPath indexFFITIM: Address in IDX: 0]]]; }]; } Closing: ^ (BOOL Finish) {Full (); }];   
 But, if you reload your collection view more than once, then you will get a lot of pain with it.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
