I want to resize NSTextView accordingly to it's content. Initially its height equals one line height and if there's more then one line of text, I want to resize it to three line height.
The problem is TextContainer size is not affected when I resize text view.
Here is screenshot to better illustrate the problem.
Text view has red background color to distinguish from scroll view, and definitely its size changed. As you can see, part of the text that is on the second line is not displayed fully as if text container were smaller than text view
Here is code I use for resizing:
-(void)unfold {
NSScrollView *scrollView = (NSScrollView *)self.superview.superview;
NSRect scrollFrame = scrollView.frame;
NSRect textFrame = self.frame;
scrollFrame.size.height=62;
scrollFrame.origin.y-=40;
textFrame.size.height=60;
self.superview.superview.frame = scrollFrame;
self.frame=textFrame;
}
I also tried to play around with text container setHeightTracksTextView or changing its size but it wouldn't work.

I'm trying to scale an NSView for a larger display when I'm testing on my Mac screen, so I can see everything in proportion.
NSRect wFrame = self.window.frame;
wFrame.origin.x = 200;
wFrame.origin.y = 100; // from bottom of my screen
wFrame.size.width = 1080 * 0.5; // so it will fit on my screen
wFrame.size.height = 1920 * 0.5;
[self.window setFrame:wFrame display:YES]; // the window is smaller, but not everything is scaled (e.g., font sizes)
That creates the correct size window, and most of the contents are drawn at half size. But, some things are not scaled.
An NSButton's title text is still the original, large size. If the button contains an image, the image is scaled properly.
The content of a WebView are not rendered at the small size.
How can I scale all of the content, including button titles and Webview content?

I wrapped my full sized NSView (and its subviews) in an NSScrollView (sized for my screen) and then set the magnification to 0.5.
In swift how can I set the width of the scroll view to be the width of the screen size?
I tried setting right leading and trailing bounds, but my aspectscalefill image keeps stretching the entire frame.
I am trying to force the view to be the width of the screen and allow vertical scrolling only.
If you want to make a scroll view with auto layout try this. No code at all so you will have to drag things out of the library to the right of Xcode.
In your view controller drag and place the scroll view size it to whatever you want but it looks like you want to make it the size of the screen. Pin all edges to the edges of the view controller. Pin trailing, leading, top, and bottom.
Now, instead of placing your items in the scroll view, place another view in the scroll view. With this new view you will place all of your items. You will most likely have to move the view up or down to place them all and resize the view. You can then place whatever constraints you want on your items. When all items are in their place, set the frame of the new view back to x = 0 and y = 0.
You will then place constraints as follows. Select the new view and pin to top, bottom, trailing, and leading and then center in container. This will make a constraint that is vertical with some negative number. In the storyboard outline select this constraint and set it to zero.
You will now be able to scroll vertically. Let me know if you have any questions.
I created a single view application, and added a UIScrollView in the storyboard with four constraints (top, left, right, bottom). And I add the following code in the viewDidLoad(). Everything works just fine. My image is only scrolling vertically, but not horizontally. No additional settings are needed.
#IBOutlet weak var scrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
// Just as an example, I make a size with same with of the view
// and twice the height of the view.
let size = CGSizeMake(
self.view.frame.size.width,
self.view.frame.size.height * 2);
// Load an image and make a image view
let image = UIImage(named: "im.jpg")!
let imageView = UIImageView(image: image)
imageView.frame = CGRect(
origin: CGPoint(x: 0, y: 0),
size: size);
imageView.contentMode = UIViewContentMode.ScaleToFill;
// Add the image view to scroll view
scrollView.addSubview(imageView)
scrollView.contentSize = size;
}
Your problem i caused by the fact that you add your elements to the scrollView from the storyBoard.
In the storyBoard you need:
1) Add the scrollView, if you need to be in the width of the screen then set it's trailing and leading spaces to superView to 0
2) uncheck the "allow horizontal scrolling" in the attribute inspector
In your code
1) set the scrollView's contentSize to what ever size you want it to be.
1.1) in your code you need to set the size of the contentView like so
scroller.contentSize = CGSizeMake(your width, your height);
This is a very important step, the scrollView will not be able to scroll if you don't set the size. Think about the scrollView as the window and the contentView as the view. If the contentView if the same size as the scrollView then the scrollView can't scroll anywhere (all of the contentView fits into the scrollView) in order to create the scrolling you need to make the contentView bigger then the scrollView itself
2) start adding your elements to the scrollView's contentView by calling
[scroller addSubView:<your view>];
this will add your views to the scrollView's contentView and will be
I'm trying to resize a UITextView to the size the text within it.
The problem is that Im using a custom font and it the text doesnt fit within the UITextView.
NSString *textToFit = #"pretty long text";
UIFont *customFont = [UIFont fontWithName:#"Museo-100" size:15];
CGSize sizeText = [textToFit sizeWithFont:customFont constrainedToSize:CGSizeMake(textFrame.size.width, 1000)];
Where textFrame is the frame of the UITextView I want to adjust its height.
Im trying different fonts and also different files of the same font and still it never adjusts its height to the height that the text fills.
I've been searching and I dont find a solution. I've tried a workaround using a UILabel and the method textRectForBounds, but still no success, something on this lines.
UILabel *auxLabel = [[UILabel alloc]init];
auxLabel.numberOfLines = 0;
auxLabel.font = [UIFont fontWithName:#"Museo-100" size:15];
auxLabel.text = //THE TEXT I WANT TO FIT IN
CGRect textSize = CGRectMake(0.0, 0.0, textDescription.frame.size.width, FLT_MAX);
CGRect frame = [auxLabel textRectForBounds:textSize limitedToNumberOfLines:0];
I think
UIView : sizeToFit
Should solve your problem.
sizeToFit Resizes and moves the receiver view so it just encloses its
subviews.
Discussion: Call this method when you want to resize the current view so that it uses the most appropriate amount of space.
Specific UIKit views resize themselves according to their own internal
needs. In some cases, if a view does not have a superview, it may size
itself to the screen bounds. Thus, if you want a given view to size
itself to its parent view, you should add it to the parent view before
calling this method.

I've a Storyboard with a UIScrollView which contains two UILabels, a UIImageView and a UITextView. The content of the UIImageView and UITextView is dynamic and so are their height.
Currently I'm doing this inside my viewDidLoad to adjust the size of the UITextView after the dynamic text is inserted:
CGRect frame = self.textView.frame;
frame.size.height = self.textView.contentSize.height;
self.textView.frame = frame;
Is this the way to change its height?
My next problem is to set the content size for the UIScrollView, to activate the scrolling. Is there a smart way to get the height of all its content or do I have to calculate the height for each element and set the sum of this as the content size of the UIScrollView?
IF you had no space in between your objects, you could make a for loop in your scrollView.subviews and add up all the heights to set as the contentSize.
As you probably don't have everything tight together, you're probably better by getting the bottom most object and adding up it's frame.origin.y and it's frame.size.height (maybe you want to have some extra space in here, but that's up to you) and that will give you your contentSize.height to keep everything in there.
I have a weird problem in a custom UITableCell subClass.This custom cell has a pair of UILables that are multi-line and can contain varying amounts of text (up to 2000 characters). The custom tableCell has a layout method where I am calculating their frame's height using the code below, taking the device orientation into account:
if (isPortrait) {
presentationTextLabelSize = [presentationTextStr sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:CGSizeMake(portraitDescriptionWidth, 2000.0f) lineBreakMode:UILineBreakModeWordWrap];
presentationTextLabelRect = CGRectMake(60.0f, 25.0f, portraitDescriptionWidth, presentationTextLabelSize.height);
} else {
presentationTextLabelSize = [presentationTextStr sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:CGSizeMake(landscapeDescriptionWidth, 2000.0f) lineBreakMode:UILineBreakModeWordWrap];
presentationTextLabelRect = CGRectMake(60.0f, 25.0f, landscapeDescriptionWidth, presentationTextLabelSize.height);
}
self.presentationTextLabel.frame = presentationTextLabelRect;
I have the label's autoResizeMask set as follows:
self.presentationTextLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
I use the same calculation in the UITableViewController to set the row height.
Everything works perfectly, the label is sized to the correct height for it's width, and the cell autoResizes on device rotation, except that when the device is rotated to landscape the label's text sometimes extends out of the label's frame to the right, clear past the edge of the tableView. If I scroll the cell out of view and back again it's back to normal. I am logging the cell's width to the console, and it is correct, yet the text extends far past that width.
Any ideas what's joing on?
Thanks
The problem is, the tableView is not reloaded when the device is rotated to landscape. So, there is mismatch in updating the texts. Use [tableView reloadData]; at the place, where you find the device is changed to landscape mode.
