应用程序在启动时崩溃。它不会每次都崩溃。执行以下代码以初始化NSCalendar对象，并用于日期和时间计算。
static NSCalendar *calendar;
+(NSCalendar*)getCalendar {
if (calendar == nil) {
calendar = [NSCalendar currentCalendar];
[calendar setFirstWeekday:1];
[calendar setMinimumDaysInFirstWeek:1];
}
return calendar;
}有时在行历setFirstWeekday:1或行历setMinimumDaysInFirstWeek:1观察到崩溃；

我认为，如果删除静态实例并引用currentCalendar，这种崩溃可能会消失：
+(NSCalendar*)getCalendar {
NSCalendar *calendar = [NSCalendar currentCalendar];
[calendar setFirstWeekday:1];
[calendar setMinimumDaysInFirstWeek:1];
return calendar;
