正常に動作するウォッチキットテーブルをセットアップしました。しかし、コンテキストに存在するはずの値で WKInterfaceTable didSelectRowAtIndex メソッドを使用しようとすると、コンテキストは null 値を返します。私が作成したテスト コンテキスト値は正常に動作し、メソッドは動作して、正しく設定された DetailInterfaceController をプッシュします。以下の InterfaceController.m のコードを参照してください。
- (void)awakeWithContext:(id)context {
[super awakeWithContext:context];
// Configure interface objects here.
[self updateWatchTable];
}
-(void)updateWatchTable{
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Cschedule" inManagedObjectContext:[[CoreDataHelper sharedHelper] context]];
[fetchRequest setEntity:entity];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"trueDate" ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObjects:sortDescriptor, nil];
[fetchRequest setSortDescriptors:sortDescriptors];
NSArray *myResults = [[[CoreDataHelper sharedHelper] context] executeFetchRequest:fetchRequest error:nil];
self.objectsTable = myResults;
NSLog(@"Schedule myResults count: %lu", (unsigned long)myResults.count);
[self.table setNumberOfRows:self.objectsTable.count withRowType:@"ScheduleTableRow"];
for (int i = 0; i < self.objectsTable.count; i++) {
ScheduleTableRow *scheduleRow = [self.table rowControllerAtIndex:i];
NSManagedObject *item = self.objectsTable[i];
scheduleRow.name.text = [NSString stringWithFormat:@"%@",[item valueForKey:@"day"]];
scheduleRow.date.text = [NSString stringWithFormat:@"%@",[item valueForKey:@"date"]];
}
}
- (void)table:(WKInterfaceTable *)table didSelectRowAtIndex:(NSInteger)rowIndex
{
// Push detail view with selected quote
NSString * scheduleDate = [[self.objectsTable objectAtIndex:rowIndex] valueForKey:@"date"];
NSString * test = @"Feb 1 2016"; //TEST date
[self pushControllerWithName:@"DetailScheduleInterfaceController" context:test]; //THIS WORKS WITH TEST date AND CORRECTLY PUSHES POPULATED DetailInterfaceController
//[self pushControllerWithName:@"DetailScheduleInterfaceController" context:scheduleDate]; //THIS PUSHES BLANK DetailInterfaceController SINCE scheduleDate IS NULL
NSLog(@"Count in objectsTable = %lu", (unsigned long)self.objectsTable.count);
NSLog(@"Value for scheduleDate = %@", scheduleDate); //THIS GIVES NULL VALUE
}
