Question

我想使用kal日历框架。但我不知道如何将其实现到tabbar应用程序中。当我看一下如何初始化kalViewController的演示时，它看起来像这样。

-(void)viewDidLoad{
    KalViewController *calendar = [[KalViewController alloc] init];
    [self.navigationController pushViewController:calendar animated:YES];
}

这有效，但它转向另一种观点。我希望它使用故事板在同一视图中显示。

我检查了KalViewController类。它没有initWithCoder:实现，如果从nibs / storyboards实例化，则调用初始化程序。

我添加了这个以使它工作：

-(id)initWithCoder:(NSCoder *)aDecoder
{
    if ((self = [super initWithCoder:aDecoder])) {

        NSDate *date = [NSDate date];
        logic = [[KalLogic alloc] initForDate:date];
        self.initialDate = date;
        self.selectedDate = date;
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(significantTimeChangeOccurred) name:UIApplicationSignificantTimeChangeNotification object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadData) name:KalDataSourceChangedNotification object:nil];
    }
    return self;
}

我只是将UIViewController拖到storybord舞台上，将它在检查器中的类更改为KalViewController，从tabbar控制器将其连接起来并且工作正常。

我创建了一个示例项目：TabbedKalTest@GitHub

当然应该记住DRY：

-(void) _configureWithDate:(NSDate *)date
{
    logic = [[KalLogic alloc] initForDate:date];
    self.initialDate = date;
    self.selectedDate = date;
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(significantTimeChangeOccurred) name:UIApplicationSignificantTimeChangeNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadData) name:KalDataSourceChangedNotification object:nil];
}

//called if created by nib/storyboard
-(id)initWithCoder:(NSCoder *)aDecoder
{
    if ((self = [super initWithCoder:aDecoder])) {
        [self _configureWithDate:[NSDate date]];
    }
    return self;
}

//the designated initializer for non-nib/storyboard creation
- (id)initWithSelectedDate:(NSDate *)date
{
  if ((self = [super init])) {
    [self _configureWithDate:date];
  }
  return self;
}

我创建了一个分支来修复此问题并发布了pull-request。
