#import <QuartzCore/QuartzCore.h> Import the above framework and include these lines in your class where textview is defined. [[self.textview layer] setBorderColor:[[UIColor grayColor] CGColor]]; [[self.textview layer] setBorderWidth:2.3]; [[self.textview layer] setCornerRadius:15]; Swift solution. self.textview.layer.borderColor = UIColor.gray.cgColor self.textview.layer.borderWidth = 2.3 self.textview.layer.cornerRadius = 15
I had the same error when I tried to multiply view.frame.height by a Double. If you are doing any math on screenBounds properties, make sure the types match.
The other answers don’t exactly explain what’s going on here, so this is the basic problem: When you write blackKey.center.x, the blackKey.center and center.x both look like struct member accesses, but they’re actually completely different things. blackKey.center is a property access, which desugars to something like [blackKey center], which in turn desugars to something like … Read more
TL;DR Swift 4.2 use theRect.inset(by: theInsets). Objective c use UIEdgeInsetsInsetRect(theRect, theInsets) Example // CGRectMake takes: left, bottom, width, height. const CGRect originalRect = CGRectMake(0, 0, 100, 50); // UIEdgeInsetsMake takes: top, left, bottom, right. const UIEdgeInsets insets = UIEdgeInsetsMake(10, 10, -20, -20); // Apply the insets… const CGRect adjustedRect = UIEdgeInsetsInsetRect(originalRect, insets); // What’s the … Read more
To answer your original question: yes, it’s possible to change just one member of a CGRect structure. This code throws no errors: myRect.size.width = 50; What is not possible, however, is to change a single member of a CGRect that is itself a property of another object. In that very common case, you would have … Read more
aView.center = CGPointMake(150, 150); // set center or aView.frame = CGRectMake( 100, 200, aView.frame.size.width, aView.frame.size.height ); // set new position exactly or aView.frame = CGRectOffset( aView.frame, 10, 10 ); // offset by an amount Edit: I didn’t compile this yet, but it should work: #define CGRectSetPos( r, x, y ) CGRectMake( x, y, r.size.width, r.size.height … Read more
Use this: if (CGRectEqualToRect(self.view.frame, rect)) { // do some stuff }
You can use this: Objective-C CGRect frame = [firstView convertRect:buttons.frame fromView:secondView]; Swift let frame = firstView.convert(buttons.frame, from:secondView) Documentation reference: https://developer.apple.com/documentation/uikit/uiview/1622498-convert
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 … Read more
