我已经使用以下步骤将Tapku日历库安装到我的项目中：Tapku Calendar demo does not work in xCode4/iOS5
太好了，进口就好了。没有错误，没有。但是日历并没有出现，即使是那些运行loadView函数的日历也没有出现。切换按钮出现[虽然我在这种情况下不使用它们进行切换]。
以下是重要提示：
此代码（来自实现）：
NSLog(@"Toggle called!");
// If calendar is off the screen, show it, else hide it (both with animations)
NSLog(@"y and x = %f & %f", _calendar2.frame.origin.y, _calendar2.frame.origin.x);
NSLog(@"height and width = %f & %f", _calendar2.frame.size.height, _calendar2.frame.size.width);
屈服于：
2012-12-11 17:16:46.294 MyApp[29078:c07] Toggle called!
2012-12-11 17:16:46.295 MyApp[29078:c07] y and x = 0.000000 & 0.000000
2012-12-11 17:16:46.295 MyApp[29078:c07] height and width = 0.000000 & 0.000000
注意y和x是如何为零，即使我将它们设置为1。这就像_calender2没有保存任何东西？

答案 0 :(得分：3)
移动线条：
_calendar2 = [[TKCalendarMonthView alloc] init];
_calendar2.delegate = self;
_calendar2.dataSource = self;
从initWithNib...到loadView的开头，然后将日历视图添加到控制器的视图中：
- (void)loadView {
[super loadView];
// Costruct the view because we aren't using a xib file
_calendar2 = [[TKCalendarMonthView alloc] init];
_calendar2.delegate = self;
_calendar2.dataSource = self;
[self.view addSubview:_calendar2];
// rest of the method unchanged....
实际上，由于您没有使用笔尖，因此不会调用initWithNib...; loadView负责创建视图。
