在视图中将Stripe PaymentKit信用卡文本字段居中

Question

I am using code from Stripe PaymentKit. They've provided the code for the PaymentViewController and I want the textfield to be centered in the view but I can't figure out how. I can change the position and width/height easily but I want it to be horizontally centered... Any ideas?

Answer 1

I found a workaround by modifying the x coordinate:

float X_Co = (self.view.frame.size.width - 290)/2;
self.paymentView = [[PTKView alloc] initWithFrame:CGRectMake(X_Co, 240, 290, 55)];

Answer 2

I placed an empty UIView inside my presenting view controller in Storyboard, set its width to be 290 and the height to be 55 (the width and height of the PTKView), set it to align center X with the Superview, and created a referencing outlet in my view controller named paymentViewArea .

Then I loaded the PTKView into that view

self.paymentView = PTKView(frame: CGRectMake(0, 0, 290, 55))
self.paymentViewArea.addSubview(self.paymentView)
