我有一个字符串变量存储日期选择器的日期,但是当我在其他函数中使用它的值时,我收到错误,如程序接收信号:"EXC_BAD_ACCESS".注意:变量是全局定义的.

代码:

    - (void) changedDate: (UIDatePicker *) picker 
    {
     if (appDelegate.dateint == 8)
     {
     NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; 

[dateFormatter setDateFormat:@"dd MMM, yyyy"];
     datestr=[dateFormatter stringFromDate:[dptpicker date]]; 
    NSLog(@"date:%@",datestr); 
    } 
    else if(appDelegate.dateint == 9) 
    { NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; 

[dateFormatter setDateFormat:@"dd MMM, yyyy"]; 
    datestr1=[dateFormatter stringFromDate:[dptpicker date]] ;
     NSLog(@"date1:%@",datestr1);
     } 
    }
