White background at the top of UITableView [duplicate] - ios

This question already has answers here:
Empty white space above UITableView inside a UIView
(9 answers)
Closed 5 years ago.
I have a UITableView below a UITextField. Strangely, the upper part of the UITableView has a white background. The tableView scrolls nicely till just below the UITextField, so it is being placed correctly below it. It is just that the upper portion is somehow getting a white background. And this portion seems to scale with respect to the height of the UITextField. i.e. if I increase the height of the textField, the white portion will increase too.
I have tried setting the adjust scroll view insets to false but to no avail.

layout and its constraints are looking fine, I think you might have added a header view in code. Can you check your delegate and data source functions in your class.

Go to storyboard and select view controller where your tableview is and
Unmark option Adjust ScrollView Insets

By default an section height and footer of 28 is added to the tableview in xib.
Change it 1 for both header and footer in the size inspector.

How to set Table view cell to occupy entire screen?

I am working on a project to get custom news feeds from Bing news. I created a custom table view cell and populated various UI items in it. But I am having a hard time to make it occupy the entire screen, it starts from extreme left and ends on the right, leaving large gap from the right margin as show in the image. Can anyone help me out, how to correctly fix it with a detailed explanation of how constraints work in Table views and Tableview cells.
Here' what it looks like in the simulator
Remove previous constraints and add constraint to your UITableView like as shown in below image.
So you UITableView will have 0 margin from edges.
Create a UITableViewController. Just drag drop a TableViewCell into it. Add identifier for that cell and use it. By default it will occupy the whole screen.
In your case I guess you might have added constraints to UITableView. Here what you should do is pin your UITableView to Top,Bottom,Right & Left or make UITableView's width equal to SuperView.

UITableView inside UIScrollView - Cell not clickable

I have a problem with a UITableView not detecting touches.
In an iPhone-only app, I have a UIViewController, which containts:
UIScrollView
UIView (let's say a content view)
Some labels
UITableView (last)
The labels have a dynamic height, because they contain some text that I must retrive from the web, so I'm using auto layout.
I'm setting the content size of the UIScrollView inside the viewDidLayoutSubviews method, and I'm doing this by summing UITableView.frame.origin.y and its height.
Here comes the problem: when the labels contain only some words and the UITableView does not exceed the iPhone screen size, everything works ok. But when they grow, and the UITableView gets pushed down, when I scroll down I can't click on the cell anymore. Also, if when loading the view the table is half visible and half not, I can click the visible cells, but if I scroll down, I can't click the others.
I'm using swift 2 and Xcode 7.
Here is an example:
Clickable:
Unclickable:
Do the following thing:
yourView.clipToBounds = true
Now, if UITableView does not appears means your UIView is not same bigger to hold down UITableView.
Make sure that your UIView height is bigger to hold the contents in it and then try to tap on it.
Updated:
If you are using AutoLayout, then do the following thing.
Give the fix height to UIView
Take the outlet of height constraint of UIView
Now, in viewDidLayoutSubviews change the constraint of UIView to UITableView contentSize height.
self.heightConstraint = self.tableView.contentSize.height
Let me know, if this helps!
Adding some info to the #Rémy Virin's answer here:
From Apple Documentation, you shouldn't embed a UITableViewinside a UIScrollView.
Important: You should not embed UIWebView or UITableView objects in UIScrollView objects. If you do so, unexpected behavior can result because touch events for the two objects can be mixed up and wrongly handled.
Addition:Solution Since you want to scroll the content above table also, the one solution is place a Header View for the Table and place the Content over there to make it Scroll along the Table View.
If you use Autolayout, no need to specify contentSize to UIScrollView as it will automatically expand by taking the height of its subview.
In your case, increase the height of the Base UIView (content view as mentioned by you) which holds the tableView when the tableView height increases.
UITableView becomes unresponsive when it extends below its container view.

UITextView size not changing size after text has wrapped until second character is typed

I have spent at least 10 hours trying to figure this out and I am stuck. I am trying to have UITextView within a UITableViewCell that automatically expands to the size of the textview when the number of lines in the text view has changed. The table cell is inside a static table view. I have looked at almost every question about this on stackoverflow and nothing seems to be working.
My test project is here.
I have created a custom class that automatically resizes the textview. It works perfectly when not in a table cell. You can see this in the example project. There are two instances of the textview; one in a regular view where the textview resizes correctly, and another in a tableview. In the table cell, it doesn't resize until the second character on the next line has been typed. It is odd, because when I log the height of the textview it says that the value of frame.size.height has changed but the text view does not change size.
One thing that worked was creating a custom table cell and then overriding the layoutSubviews method but the problem with that was the bottom border line on the table cell lagged and created an ugly line across the screen. I looked for a solution but could not figure out how to prevent this.
Thank you for taking the time to read this.
I have tried your project and make it work by :
In Tbl View Controller in storyboard, remove AutoLayout. Although you don't set any constraint for the text view, at run time some constraints will be set automatically, and that will clash when the text view tries to change its frame.
In storyboard, set the autoresizing mask of the text view to default (Fix top, Fix Left, flexible right margin, flexible bottom margin).
It will work correctly now.

Unnecessary padding in tableview cell iOS?

I am developing an enterprise iOS application that uses splitview to display information. My split view, tabbars are all in place and seem to work fine. I have a tableview in the left pane of the splitview. The tableview has custom cells which contain an image view and several textview (removed textviews in the img) The height of the image view is same as the row height of the tableview and tableview cell. I wish to achieve a row height of 182 points. Even though I have kept all size same I see a padding on the left, top and bottom of the tableviewcell. In the tableview the cells thus appear separated by the background color. The tableview has no separators set. The only problem I see is that the image used inside the cell is only 168 points in height.
I did the same stuff in the detail view in the split view however now I see the table cells occupying the entire area designated to it. The image inside this detail view cell is only 160 points in height yet to I do not see that "padding" effect.
I have attached a sample screenshot, pls let me know where to fix it?

Is it possible set width of UITableView or cells on iPad

Since it's not possible to "hook onto" this and get an answer, and none of the answers do it, I thought I'd ask if anyone ever succeeded in doing it and if so, how.
I've created a New File, selected subclass UITableViewController with XIB, and everything works fine. I can set the height of everything (with delegate methods), but not the frame of anything.
Right now the table is as wide as the iPad and it looks kinda corny with the short titles in each cell - and there is nothing in IB that changes the stretching or layout.
I'd be happy with any solution that causes the cells to shrink horizontally - like margins. I tried scrollview insets in IB, but they only add to the size of the scrollview so it gets bigger than the screen.
I think that you want to subclass UViewController and add a UITableView to it, and make it the size you want in IB.
