Using UITextView, I am having the following issue. I am using iOS 7 and Xcode 5.
I first intended to use a simple UITextField, but since I need two lines of text I have gone to UITextView.
Having enough space for the two lines, this is fine. I do not need to have the scroll.
Therefore I did:
myTextView.scrollEnabled=NO;
But this is where problems start:
I do not have two lines displayed any more, just one (partly invisible). And of course this is not what I want.
How can I keep my two lines and get rid of the scroll?

I have started to use tmux and noticed that the lines that seperate the different panes are not entirely straight, instead there are small bumps. I think it might have something to do with the font, my thought is that characters from one "character-field" are overlapping into the next, which creates the little bumps. Does anyone know how I can fix this and get a straight line without bumps?
The font I use: Menlo

The problem was actually the terminal emulator I used, Alacritty, which lets some characters reach outside of their cell. To solve this issue, I switched to Kitty, which has better support for preventing characters from overflowing into other cells.
So I have two big monitors. So I want to "stream" a small important part of the right monitor to the left. I have a specific part like 100x200pixels to the right of my screen I want to show at the very left.
I can do this but in a very ineffektive way by getting the bitmap from the right and displaying it in a gui to the left, then putting it in a loop where I create and destroy the gui showing an updated bitmap every 5 seconds. But this causes flickering and seems like a bad solution.
What is a better way to do this?
One thing that may help and reduce flicker is to use GuiControl. In your loop, instead of recreating the GUI each time, just update the picture control's contents.
GuiControl ,, picture_control_name , %A_Desktop%\updated_pic.bmp
Having struggles trying to get the following view to work across devices, this is just one of many of my auto-layout issues. I have some text next to a UISwitch, on devices that are large enough I am happy for the text to be on a single line but on smaller devices the text can be split across multiple lines, I just can't get it to work correctly, it either appears like the screenshot or somewhere else messed up no matter what constraints I try to apply.
The middle image is iPhone 7.
I know this question is old, but it is something I encountered myself recently.
In the storyboard, you should set the label's horizontal Content Compression Resistance Priority to 749.
Looks like the trailing side of the switch is not constrained to align with the trailing side of the text field and other UI elements. Also make sure there is no constraint for the width of the text, as this is what will stretch.
I need your advice on a rather simple question - I'd like to draw an image in datagridview cell.
The problem is that the number of rows can be rather big: up to 100 000 of rows, sometimes more than that.
I tried using CellFormating but in this case the grid is blinking. I tried to set DoubleBuffered = true but it got only worse - the window hung and CPU usage was showing 100%. Other controls stopped drawing itself. Moreover it did not help blinking too much (even on several rows).
So I tried to use source DataTable and added a column. Than I filled it with images. But it was a fail: app memory grew very fast on a big datatable and it just crashed.
Also I tried using DataSourceChanged event and settings images like row[cell].Value = . It fires but grid works strange: sometimes it shows images, sometimes it does not. I read that you must set underlying data to make this working but it caused memory problems as I wrote.
I changed image to text so far but certainly I'd like to have moe user-friendly UI.
What can I do in this case? Probably I should give up images or change display logic at all? I.e. use virtual mode. I tried to use it long ago but I had some difficulties so I just skipped this way and my grid is working in non-virtual mode.
Ok, I eventually used CellFormatting event. It looks like blinking has gone away without my help. Images are looking fine.
I have a QCView that loads a Quartz file which gives you iSights feedback (basically like a QTCaptureView)
Everything displays fine
The button simply takes a snapshot using the following simple lines of code
- (void)takePicture:(id)sender {NSImage *currentImage = [outputView valueForOutputKey:#"ImageOutput"];
[[currentImage TIFFRepresentation] writeToFile:#"/Users/hendo13/Desktop/capture.tiff" atomically:NO];}
The exported image however has some very wonky colouring issues like so:

No filters of any sort have been applied. Does anyone know what is causing this?
It's inverted. You can use the CIInvert filter to correct it (assuming there's no way to correct the actual output of the QC view).
Oh, and I think the blue and green alpha channels are the wrong way around, too (possibly an endianness problem?). If you go with the CIInvert solution, you can use CIColorMatrix to rearrange the channels, swapping blue and green back to their proper places. Here's a tutorial I wrote for it—I wrote it for the user interface in Core Image Fun House, but using it programmatically shouldn't be too hard once you understand how the filter works.
