I'm creating a comment section much like the one Facebook uses for it's messaging section in it's iOS app. I want the UITextView to resize the height so the text I'm typing fits inside it rather than you having to scroll to see the text that overflows. Any ideas how I might go about doing this? I've looked into maybe using a CGRect that is assigned to the size and height of the text view which then matches the content size: CGRect textFrame = textView.frame; textFrame.size.height = textView.contentSize.height; textView.frame = textFrame; I assume I need some sort of function that detects when

How can I, given two different CGPoints , turn them into an CGRect ? Example: CGPoint p1 = CGPointMake(0,10); CGPoint p2 = CGPointMake(10,0); How can I turn this into a CGRect ? This will take two arbitrary points and give you the CGRect that has them as opposite corners. CGRect r = CGRectMake(MIN(p1.x, p2.x), MIN(p1.y, p2.y), fabs(p1.x - p2.x), fabs(p1.y - p2.y)); The smaller x value paired with the smaller y value will always be the origin of the rect (first two arguments). The absolute value of the difference between x values will be the width, and between y values the height. colinta A

Is there a way to verify if a CGPoint is inside a specific CGRect . An example would be: I'm dragging a UIImageView and I want to verify if its central point CGPoint is inside another UIImageView Ole Begemann Swift 4 let view = ... let point = ... view.bounds.contains(point) Objective-C Use CGRectContainsPoint() : bool CGRectContainsPoint(CGRect rect, CGPoint point); Parameters rect The rectangle to examine. point The point to examine. Return Value true if the rectangle is not null or empty and the point is located within the rectangle; otherwise, false. A point is considered inside the

When I'm using this code, I get an error: let d = translation.x / CGRectGetWidth(pan.view!.bounds) * 0.5 'CGRectGetWidth' has been replaced by property 'CGRect.width' How can I fix this? You should get the width directly from the bounds property. let d = translation.x / pan.view!.bounds.width * 0.5 CGRectGetWidth has been removed in swift 3 and now you can get width directly let d = translation.x / (pan.view!.bounds.width) * 0.5 hope its works.. 来源： https://stackoverflow.com/questions/48786472/error-while-using-property-cgrectgetwidth-it-says-it-was-replaced-with-cgrec

I have placed one label on view and view's frame is CGRectMake(0,0,270,203) . Now I have to take screen shot of view with CGRectMake(0,0,800,600) . So I have to convert label from old rect to new rect . here is code which I used to take screen shot: CGRect rect = [view bounds]; UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f); CGContextRef context = UIGraphicsGetCurrentContext(); [view.layer renderInContext:context]; UIImage *capturedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); Here is the code which I used to convert point: CGRect f = [view

I'm creating a view (using card.io), and I want the view to cover the full screen. Its only covering about 2/3rds of the screen atm. Heres the code: CardIOView *cardIOView = [[CardIOView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)]; Here is an example Dave from card.io here. When you create a CardIOView , its frame will take on whatever size you set. However, the camera view within the (transparent) CardIOView will have the standard iOS camera form factor of 4:3. So if the CardIOView is 320 points wide, then its camera view will be ~426 points

I want the button to be reactive to tap only in the custom polygonal shape that I create and not in the CGRect frame. button.frame only supports CGRect. Here is an example of a button that only responds to touches within a certain area. class MyButton: UIButton { var path: UIBezierPath! override func awakeFromNib() { backgroundColor = UIColor.greenColor() addTarget(self, action: #selector(touchDown), forControlEvents: .TouchDown) } override func drawRect(rect: CGRect) { path = UIBezierPath() path.moveToPoint(CGPointMake(150, 10)) path.addLineToPoint(CGPointMake(200, 10)) path.addLineToPoint
