    <p>Cocoa, not iOS. I have an array of items that is backing a UITableview. I go through the array and perform a series of tasks, specifically, I'm calling an external script executable with NSTask. While the task is executing, I want to update the "Status" column in the UITableView. </p> <p>I update the value of the array that's associated to the column, and then call [_TableView reloadData], but No changes in the UI, until all of the processing is done.</p> <pre><code> for (int ix = 0; ix &lt; [_sceneList count]; ix++) { // update status in array backing the TableView [[_sceneList objectAtIndex:ix] setRenderStatus:@"Rendering"]; [_tableView reloadData]; // execute command via shell script [self runScript:@"run_script.bash":appPath:outputFormat:showGUI:threadCnt:resolution:renderFile:outputFile]; [[_sceneList objectAtIndex:ix] setRenderStatus:@"Complete"]; [_tableView reloadData]; } </code></pre> <p>code for run_script:</p> <pre><code>-(void) runScript:(NSString*)scriptName:(NSString*)appPath:(NSString*)outputFormat:(NSString*)showGUI:(NSString*)threadCnt:(NSString*)resolution:(NSString*)renderFile:(NSString*)outputFile; { NSTask *task; task = [[NSTask alloc] init]; NSArray *arguments; NSString* newpath = [NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] resourcePath] , scriptName]; [task setLaunchPath: newpath]; arguments = [NSArray arrayWithObjects:appPath, showGUI, renderFile, outputFile, outputFormat, threadCnt, resolution ,nil]; [task setArguments: arguments]; NSPipe *pipe; pipe = [NSPipe pipe]; [task setStandardOutput: pipe]; [task setStandardInput:[NSPipe pipe]]; NSFileHandle *file; file = [pipe fileHandleForReading]; [task launch]; NSData *data; data = [file readDataToEndOfFile]; NSString *string; string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; NSLog (@"script returned:\n%@", string); } </code></pre> <p>Any ideas why the UI isn't updating?</p> <p>Is there some sort of "tableview:updateRow" method I should use?</p> <p>_mike</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
