There is lots of data present in Internet but I am not able to use these. Please help me to do this in cocoa. Thanks in advance and appreciate any help. 回答1: Each table column has a method setSortDescriptorPrototype Sort descriptors are ways of telling the array how to sort itself (ascending, descending, ignoring case etc.) Iterate over each of the

问题 I have a master-detail kind of application OS X 10.9 only: An NSTableView on the left side of the window, the details as NSTextFields on the right side.

问题 This is my table view delegate: - (void)tableView:(NSTableView *)tableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)tableColumn row:(int)row { id theRecord; NSMutableString *gid; theRecord = [tableDataSource objectAtIndex:row]; gid = [theRecord objectForKey:@"gid"]; if (([gid intValue] % 2) != 0) { [aCell setDrawsBackground: YES]; [aCell setBackgroundColor: [NSColor colorWithCalibratedRed: 237.0 / 255.0 green: 243.0 / 255.0 blue: 254.0 / 255.0 alpha: 1.0]]; } else { [aCell

问题 I have an NSTableView in which I'm changing the colour of the text in a particular column, but when a row is selected, the text does not change to a more appropriate colour so that it's readable. Finder's Date Modified, Size, and Kind columns have grey text, and when you select a file/folder row, the grey text changes to white (so that it's readable within the blue highlight). I can't find a magic checkbox on XCode to enable this behaviour by default, so does anybody know how I might achieve

问题 I have a NSAttributedString that I'm using in a NSTextFieldCell. It makes several clickable url links and puts a big NSAttributedString inside the NSTextFieldCell. Whenever I am viewing the NSTextFieldCell normally and it's highlighted, I cannot click on the links. If I set the TableView so I can edit each column or row, when I click twice, go into Edit mode and view the NSTextFieldCell contents, my links show up and are clickable. When I click away from the row, I can no longer see clickable

问题 To start, there's an NSArrayController ("Servers") whose content is an array of "server" objects. I also have an NSTableView with a column. The column is bound to Server's "arrangedObjects.status" property. I use a custom NSValueConverter to make that status into an image for the column's dataCell which is an NSImageCell . What I don't understand is why the images that show up in the column are correct, but consistently faded out. Just to test, I have the same image outside the table view for

问题 I've got an NSTableView. While editing, if I hit tab it automatically jumps me to the next column. This is fantastic, but when I'm editing the field in the last column and I hit tab, I'd like focus to jump to the first column of the NEXT row. Any suggestions? Thanks to Michael for the starting code, it was very close to what ended up working! Here is the final code that I used, hope it will be helpful to someone else: - (void) textDidEndEditing: (NSNotification *) notification { NSInteger

问题 I am new to the Mac. I am trying to update a particular cell in NSTableView without using -reloadData , as -reloadData updates the whole table. I have tried everything but all was in vain. I am trying to do something similar to what we used to do in CListCtrl in MFC or in .NET. 回答1: Have a look at reloadDataForRowIndexes:columnIndexes: method. To update a single cell the following should work: [yourTable reloadDataForRowIndexes:[NSIndexSet indexSetWithIndex:row] columnIndexes:[NSIndexSet

问题 I have an NSTableView with 4 columns. I also have a custom background color for each row. The only problem is I have these ugly white spaces where the gridlines would go in both the horizontal and vertical axis. I have both unchecked in IB, but they still show up. How can I get rid of the vertical ones and change the color and size of the horizontal ones? Here's what I see: alt text http://img815.imageshack.us/img815/9030/homex.png 回答1: To get rid of vertical spaces but keep the horizontal

问题 El Capitan introduced San Francisco system font, which has proportional digits by default. This makes numbers in table columns look jagged and hard to compare: I'd like to enable fixed-width numbers option for the font, but keep using the default system font and keep backwards compatibility with earlier versions of OS X. In Interface Builder selecting font > Font Panel > Typography > Monospaced Numbers does not affect the font (XIB file remains unchanged). What's the right way to set
