I want to inset the table view separator by 10 points from the current automatic inset so it respects the safe area etc. but when I set it in the storyboard it doesn't work as documented.
Turns out the settings in the storyboard are not being respected.
When I added the settings in code then it worked as expected.
tableView.separatorInsetReference = .fromAutomaticInsets
tableView.separatorInset = .init(top: 0, left: 10, bottom: 0, right: 0)

I have been using MessageKit for my live chat feature for my application. One of the issues I am running into is that long messages just look very weird on the screen as the width of the bubbles doesn't seem to be restricted. I wanted to figure out a way to be able to set the maximum width of the chat bubbles so that they format more like a text conversation on the native imessage application.
Currently my messages look like this, but I would want the message below to be less wide and taller:
You can adjust the right/left padding for incoming/outgoing messages respectively.
The default padding is:
public var incomingMessagePadding = UIEdgeInsets(top: 0, left: 4, bottom: 0, right: 30)
public var outgoingMessagePadding = UIEdgeInsets(top: 0, left: 30, bottom: 0, right: 4)
And you can set the padding on the layout object in your messages view controller like this:
let layout = messagesCollectionView.collectionViewLayout as? MessagesCollectionViewFlowLayout
layout?.setMessageIncomingMessagePadding(UIEdgeInsets(top: 0, left: 4, bottom: 0, right: 50))
layout?.setMessageOutgoingMessagePadding(UIEdgeInsets(top: 0, left: 60, bottom: 0, right: 4))
You can see more examples of layout changes in the AdvancedExampleViewController in the MessageKit example project.
It seems that the library that you are using has already a width set, but in my chat (which is customised) I have a greater than or equal than 0 width constraint a a less than or equal than MAX_WIDTH constraint a leading constraint = 0 and a 'trailing constraint = 0' and those last two I get rid of the leading or trailing depending on if it is the sender or receiver of the message.
I want to put scrollViewIndicator just a bit more outside(right) of scrollView. But It doesn't go even if I set self.mainMenuCollectionView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 10, 0, 0);. It might because of inset works as padding and not going out of bounds of scrollView. It stays in the border.
It works for putting indise(left) of the view.
It would be really helpful if you know how can I achieve that.
N: normal
S: It is possible
W: How I want
You need to setup opposite side with minus sign like:
self.mainMenuCollectionView.scrollIndicatorInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: -10)
Don't forget disable clipsToBounds for getting visible subviews outside:
self.mainMenuCollectionView.clipsToBounds = false
I want to place information text in main scene of the application. When ı place a text view, its content starts at the middle. There is a between the text and top boundary of the TextView.
How can I make the text start at the first line of the TextView ?
You can set the contentOffset property of textView to zero like
textView.setContentOffset(CGPoint.zero, animated: false)
Swift 3
textView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
I Tried to give space like this self.tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 20, right: 0)
but its not taking can any one suggests how to do that i need space in top of Types of homes . this form design in table view enter image description here
There are many great examples on SO to remove the left padding of a UITextView.
How to lose margin/padding in UITextView?
However, I need to remove the right padding too.
I have tried...
[tv setContentInset: UIEdgeInsetsMake(-4,-8,-8,-X)];//where X is any integer
and just about every other permutation of the last two values to remove the padding and nothing seems to work. Have also tried
[tv sizeToFit];
[tv setTextAlignment:[NSTextAlignmentRight]];
The following Text in the Textview says "00"
Although it is iOS 7 only, an extremely clean solution is to set the textView's textContainerInsets as such:
[textView setTextContainerInset:UIEdgeInsetsZero];
textView.textContainer.lineFragmentPadding = 0; // to remove left padding
This will effectively remove all padding (insets) around the text inside the text view. If your deployment target is iOS 7+ then this is the best solution thus far.
To completely remove all padding, the lineFragmentPadding must be taken into account.
let padding = textView.textContainer.lineFragmentPadding
textView.textContainerInset = UIEdgeInsets(top: 0, left: -padding, bottom: 0, right: -padding)
The lineFragmentPadding default value is 5, and is at the beginning and end of fragment rectangle.
Some answers suggested setting lineFragmentPadding to 0. However, as per discussed in the doc, it is not designed to express text margins. So do not set it to 0.
Swift 4 version for the OA
self.tDescription.textContainerInset = UIEdgeInsets.zero
self.tDescription.textContainer.lineFragmentPadding = 0
For iOS 11.7
Following code worked for me:
textView.textContainer.lineFragmentPadding = CGFloat(0.0)
textView.textContainerInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
textView.contentInset = UIEdgeInsets(top: 0,left: 0,bottom: 0,right: 0)
From the Official Documentation:
textContainerInset
: It is possible to set the text container and view sizes and resizing behavior so that the inset cannot be maintained exactly, although the text system tries to maintain the inset wherever possible.
In any case, the textContainerOrigin and size of the text container are authoritative as to the location of the text container within the view.
The text itself can have an additional inset, inside the text container, specified by the lineFragmentPadding method of NSTextContainer.
Please try sub-classing the UITextView and overriding the following method:
- (id)styleString
{
return [[super styleString] stringByAppendingString:#"; line-height: 1.6em;margin-right: 30px; margin-left: 0px; margin-top: 0px;"];
}
Apparently; you can tweak the margin-left, margin-top & whatever you want ;)
My problem is solved this way
if([Utils isiOS7orHigher]){
commentView.textContainerInset = UIEdgeInsetsZero;
}else {
commentView.contentInset = UIEdgeInsetsMake(-11,-8,0,0);
}
