How to add an action to a UIButton -


I am searching for this answer online, and leaves every post for that part where really Writing code is an action. I have a simple interactive UIButton and if I can only see a template of a code which is "written code for action", then it would be super helpful !!! (This iPad is for iOS 7)

This is as far as I can get ... 

  UIButton * button = [UIButton buttonWithType: UIButtonTypeRoundedRect]; [Button addTarget: auto-action: @sillector (one method :) control events: UIControlEventTeaDown]; [Button Settital: @ State for "Show View": UIC ControllantAnnoral]; Button.frame = CGRectMake (80.0, 210.0, 160.0, 40.0); [See adviewview: button];   
 I think that I understand how this is a potential action set, but where did I write the actual code for self action?  
  
 
 
 I already responded to it, want to expand it, both responses are correct But I have to tell how all this works.    [Button addTarget: Self-action: @ Selector (aMethod :) Control events: UIControllViewTouchdown];   
 First to see;  targets .  
 The goal is a square, an example of any class. The only requirement for this class is that it has to implement the  verb .  
  Actions  is the method you can invite when pressing the button.  
  @selector (aMethod :)  Actually think of it as a method signature. Since the objective is a dynamic language,  aMethod:  does not require existence, but if your program is not, then it will crash.  
 So if we keep all this together, whenever I want to press this button:  
 System  verb   will call for example.  
 And the method itself for this, it can look like this  
  - (zero) aMethod: (ID) sender {}   < / Div>

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...
