ios - CGAffineTransformRotate doesn't work like expect -


इस सवाल का पहले से ही एक उत्तर है: < / P>

    मेरा कोड का पालन करें <पूर्व> self.view1.layer.anchorPoint = सीजीपीईएक्समेक (1.0, 0.5); CGAffineTransform को बदलने = CGAffineTransformRotate (self.view1.transform, M_PI / 2); Self.view1.transform = transform;

    मेरा यूआई जैसा है

    छवि विवरण दर्ज करें यहाँ

    हल्के हरे रंग का पृष्ठभूमि दृश्य 1 है, इसमें एक सबव्यू एक लेबल है। अगर मैं कोड चलाता हूं, तो मेरी राय में दृश्य और लेबल प्रगतिदृश्य के बाएं बिंदु के आसपास M_PI / 2 घुमाएगा। लेकिन सच्चाई का अनुसरण है:

    यहां छवि विवरण दर्ज करें

    जोड़ें 

      NSLog (@ "% @", self.view1);   
     स्वयं की जांच करने के लिए। View1 - एक पृष्ठभूमि दृश्य है, लेबल नहीं। इसके अलावा मुझे लगता है कि आपको एंचपॉइंट बदलना होगा।

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...
