ios - UIImagePickerController, custom UIButton and AutoLayout -

-

I'm trying to put a custom button in the UIImagePickerController using the lack of auto-layout; 

  - (zero) createTimerButtonFor: (UIImagePickerController *) picker {UIButton * button = [UIButton buttonWithType: UIButtonTypeCustom]; [Button Settital: @ State for "Timer": UControllStateAnimal]; NSLayoutConstraint * constraint1 = [NSLayoutConstraint constraintWithItem: picker.view feature: NSLayoutAttributeCenterX relatedBy: NSLayoutRelationEqual toItem: Button feature: NSLayoutAttributeCenterX multiplier: 1 constant: 0]; NSLayoutConstraint * constraint2 = [NSLayoutConstraint constraintWithItem: picker.view feature: NSLayoutAttributeTop relatedBy: NSLayoutRelationEqual toItem: Button feature: NSLayoutAttributeTop multiplier: 1 constant: 0]; NSLayoutConstraint * heightConstraint = [NSLayoutConstraint constraintWithItem: Button feature: NSLayoutAttributeHeight relatedBy: NSLayoutRelationEqual toItem: nil attribute: NSLayoutAttributeNotAnAttribute multiplier: 1.0 constant: 100.0]; NSLayoutConstraint * widthConstraint = [NSLayoutConstraint constraintWithItem: Button feature: NSLayoutAttributeWidth relatedBy: NSLayoutRelationEqual toItem: nil attribute: NSLayoutAttributeNotAnAttribute multiplier: 1.0 constant: 100.0]; [Invoice options] AddSubview: button]; [Picker. Endorsement: barrier 1]; [Elapsed. Add View Hint: Obligate 2]; [Add button: height restraint]; [Add button tool: width control]; }   
 Is this also possible? Am I doing something wrong?   
 
 
 Dejiar, I see that the button would be very difficult to add picker and transfer it to you Give autolayout for I think that it can not use fully automatic layout  
 I have tried to disable the rotation, but for the first iOS 8 work properly on all the tricks iOS 8 Are not doing  
 This is an overlay view and buttons in your overlay view because you have full control of the overlay view class.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
