iOS应用中的iOS 8

Question

返回回历历年我有一个iOS应用和它的iOS高达7做工精细

我生成列表车型年从1970年到当前年份。继承人的代码

NSDateComponents *components = [[NSCalendar currentCalendar] components:NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit fromDate:[NSDate date]]; 

NSInteger currentYear = [components year]; 
DLog(@"current year = %ld", (long)currentYear) 

for (NSInteger yearStart = (currentYear + 1); yearStart >= kHJVehicleStartingModelYear ; yearStart--) { 
    [self.carModels addObject:[NSString stringWithFormat:@"%ld", (long)yearStart]]; 
} 

的问题是，在iOS的8运行取决于区域设置，当它返回回历的当年。例如它将返回1435而不是2014.并且循环不执行以生成模型列表。

如何在iOS 8中获取公历当年？

您刚才创建的NSCalendar实例与NSGregorianCalendar类型：

NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 
NSDateComponents *components = [gregorianCalendar components:NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit fromDate:[NSDate date]];
