ios - invalid operands to binary expression ('NSString *' and 'NSString *') -


मेरे पास निम्न कोड है: 

  NSString * String = TextField1.text + TextField2।   
 यह त्रुटि दे रही है:  -बायरी अभिव्यक्ति ('NSString *' और 'NSString *') के लिए मान्य ऑपरेंसेस    < P> 
 
 आप इसे ऐसा नहीं कर सकते, क्योंकि उद्देश्य- concatenation के लिए '+' ऑपरेटर का उपयोग नहीं करता  
 इस तरह से काम करना चाहिए:  
  NSString * concat = [NSString stringWithFormat @ "% @% @", TextField1.text, TextField2.text];   
 या  
  NSString * concat = [TextField1.text stringByAppendingString: TextField2.text];   
 आशा है कि यह आपके लिए काम करता है;)

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...
