日历API变化

http://code.google.com/p/scm-subversion/source/browse/trunk/iPhone/CalendarTest/?r=4#CalendarTest%253Fstate%253Dclosed 日历API变化

我正在使用上面提到的Calendar API。在CalendarTestViewController.m类中，我们获取日期。现在我已经声明了一个全局变量nsstring类型，我想通过使用全局变量将该日期用于另一个新类。我已经尝试了很多次，但无法获得输出结果。如果有人知道如何通过Calendar API使用所选日期，那么请给我一些解决方案。

在此先感谢。

CODE

- (void)calendarView:(KLCalendarView *)calendarView tappedTile:(KLTile *)aTile{ 
NSLog(@"Date Selected is %@",[aTile date]); 
str=(NSString *)[aTile date]; 
} 
NSLog(@"str:%@",str); 
glbdate1 = (NSString *)[aTile date]; 
NSLog(@"glbdate1:%@",glbdate1); 
} 
//I have declared the glbdate1 variable globally in app delegate file and i have made the new class calenderview 
//I want to display the date in textfield by using global variable. Here is code in calenderview 

-(void)viewWillAppear:(BOOL)animated { 
if ([glbdate1 length] != 0) 
    { 
    from.text = glbdate1; 
    } 
}

添加笏ü甲肝试过的一些代码.. – KingofBliss

- （空）calendarView：（KLCalendarView *）calendarView tappedTile：（KLTile *）aTile { \t的NSLog（@ “选择的日期是％@”，[aTile date]）; （@“str：％@”，str）;} \t str =（NSString *）[aTile date];} \t NSLog \t \t glbdate1 =（NSString *）[aTile date];我已经在应用程序委托文件中全局声明了glbdate1变量，并且我已经创建了新的类calenderview我想通过使用全局变量在文本字段中显示日期。这里是calenderview中的代码 - （void）viewWillAppear：（BOOL）动画 if（[glbdate1 length]！= 0）{ \t from.text = glbdate1; } –

你必须给的NSDate转换为NSString的如下，

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-mm-dd HH:mm:ss"]; 
NSString *dateString=[dateFormatter stringFromDate:date];

那么同样的NSString值可以被转换成NSDate的作为，

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-mm-dd HH:mm:ss"]; 
NSDate *dateFromString=[dateFormatter dateFromString:dateString];

我希望这可以帮助你....
