“column”

I have a health fitness app that I need to track my users in a grid.On the left hand column of the grid I would like to have a ring for each person as in Apple Watch. Rather than playing with my own terrible graphics skills, does Apple have anything that would be of use?https://developer.apple.com/reference/healthkitui/hkactivityringview

Whenever I get linker errors when building an iOS app. The linker errors appear in the left column like this:But when I click on them nothing happens. I can't see any kind of traceback or information about what caused the error. I can't even copy and paste what's in the column to try and google it. Is Xcode supposed to be this way? How can I fix this?I'm using Xcode 8 on Mac OS X 10.12.14

Hi,I have read many tutorials about Core data.Unfortunately I can't understand some of the way it works.For instance , I have two Entities Sale and Products.Coming from SQL I thing that I have in each sale to have a reference to products.How ti happens in Core data.I see some relations, but what exactly they relate?And where we bind the values from particular column from peoducts with sales?How we make left joint search?From my current experiance I find Core data very anoyng, but from the other side I know that millions of people use it, so the dumb shoould be me.Thank you in advance of all that help!

This sounds like a silly question but I know how to search through a CKRecord table based on a value from one of its columns. But I don't know how to search for a record with a certain RecordID. I have the record's RecordID and now need to find it and load up it's data once it's found.

I´m trying to create a table with 3 columns in xcode. How can i pin the 3rd column to the right boarder? Now, when i´m enlarge the window, a kind of 4th column appears. I want to keep the window resizable. So there has to be a way to fix the 3rd column to the right boarder. And make the middle column resizable instead.https://pasteboard.co/cgbvIwMhi.png

Last couple of weeks I've been working on developing a simple proof-of-concept application in which a 3D model is projected over a specific Augmented Reality marker (in my case I am using Aruco markers) in IOS (with Swift and Objective-C)I calibrated an Ipad Camera with a specific fixed lens position and used that to estimate the pose of the AR marker (which from my debug analysis seem pretty accurate). The problem seems (surprise, surprise) when I try to use SceneKit scene to project a model over the marker.I am aware that the axis in opencv and SceneKit are different (Y and Z) and already done this correction as well as the row order/column order difference between the two libraries.After constructing the projection matrix, I apply that same transform to the 3D model and from my debug analysis the object seems to be translated to the desired position and with the desired rotation. The problem is that it never does overlap the specific image pixel position of the marker. I am using a AVCapturePrevie

What does it mean that Line table file: 'MPTableView.m' line 579, column 33 with start address 0x00000001001a0540It seems not a bug😕

What does it mean that Line table file: 'MPTableView.m' line 579, column 33 with start address 0x00000001001a0540,,it seems can not to be a bug, just a dictionary initialized.Thanks

Hi there!the question is about UITableView. In my ipad app I'm planning to use single column UITableView with many rows where every row will have complex views embedded inside row cell in the column. By complex view I mean a view that consists of a dozen or so controls like UIButton, UITextField, etc.I'm afraid of performance.Will such table view scroll smoothly ?Thanks!

I must be missing something simple. I want to make a 2D array where each column has two rows, a name string and a dictionary. So here's an example with four strings. I want to attach a dictionary to each string. A few things I've tried (in Playgorund) are shown.var myNames = [Home, Accesory, Service, Characterstic] // My array of name strings var myDict: [String: Any] = [ // The dictionary I want to attach to each string name addtionalRows : 1, cellIdentifier : idCellNormal, isExpandable : true, isExpanded : false, isVisible : true, primaryTitle : , secondaryTitle : Fullname, value : ] var test2DArray = [[String](), [String: Any]()] // This throws an error var test2DArray = [[String](), [String: Any]()] as [Any] // This does not cause an error, but doesn't seem to work test2DArray = [myNames, myDict] // Likewise, this does not cause an error but it doesn't fill in the array for row in HomekitRows { test.append(HomekitRows[row], cellProps) // This fails if the as [Any] form above is used }What am I m

Is there a way with Core Data to store a non-standard property value to a string entity attribute? I attempted to do this by creating an NSValueTransformer subclass that transforms NSURL to NSString, simply returning the result of NSURL:absoluteString. My transformer also returns [NSString class] from +transformedValueClass. I then created a transformable type attribute, aUrl, on my entity in the model editor, set the transformer name to my transfomer, and the custom class to NSURL. My NSManagedObject subclass has a correlating @property (nonatomic) NSURL *aUrl. When I assign an NSURL object to that property and attempt to save the NSManagedObjectContext, the app crashes with the following exception.2017-06-30 06:28:15.257 PhotoLocations[73116:3990254] -[__NSCFString bytes]: unrecognized selector sent to instance 0x608000075bc0 2017-06-30 06:28:15.292 PhotoLocations[73116:3990254] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString bytes]: unrecognized selector

G'day scriptersI've got an 8 column Outline View Table, each column of which has a Check Box installed. I need to add more rows, and each Check Box needs a unique Title, and the ability to alter the State. A total of 276 unique Check Boxes.I just cannot get the code right, and Shane Stanley's Explored 5 doesn't help. In interface builder I have defined the value of each Check Box to the key 'state', and the title to the key 'title'.'Saving errors with (the last part), ', {Extensions1CB:{|title|:X-Face, state:true}, Extensions2CB:{|title|:XPM, state:true}, Extensions3CB:{|title|:XWD, state:true}, Extensions4CB:{|title|:YUV, state:true}, Extensions5CB:{|title|:, state:false}, Extensions6CB:{|title|:, state:false}, Extensions7CB:{|title|:, state:false}, Extensions8CB:{|title|:, state:false}}} doesn’t understand the “writeToFile_atomically_” message'.Columns are defined as Extensions1CB, Extensions2CB, Extensions3CB, Extensions4CB, Extensions5CB, Extensions6CB, Extensions7CB, Extensions
