iOS-獲取2年以上的月份和年份

Question

我是iOS的新手，我很難在2年內獲得數月和數年的收入。我把它們放入NSArray。我所能得到的只有一年，但除此之外，這些年份不會增加以反映年份的變化。請幫忙？由於

NSDate *todayDate = [NSDate date]; 
NSDateComponents *todayComponents=[[NSCalendar currentCalendar]  components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:todayDate]; 
NSMutableArray *monthNameArray = [[NSMutableArray alloc] init]; 

int currentMonth = [todayComponents month]; 
int currentYear = [todayComponents year]; 
int nextYear = currentYear + 1; 

int month = 1; 
int year; 
for(int m = currentMonth ; month <= 12; m++){ 

    int nextMonth = m % 12; 

    if(nextMonth < currentMonth){ 
     year = nextYear; 
    } else { 
     year = currentYear; 
    } 
    NSString *allMonths = [NSString stringWithFormat:@"%@ %d",[[dateFormatter monthSymbols]objectAtIndex:nextMonth], year]; 
    [monthNameArray addObject:allMonths]; 
    month++;

for循環退出之前經歷12次迭代，因爲它與currentMonth而不是1初始化，所以結果是沒有得到明年的月份。另外，for循環不會增加到12以上，所以你不會超過12個月 - 這不是兩年。

int month = currentMonth-1; // Make zero-based for use with monthSymbols 
int year = currentYear; 
for(int m = 0 ; m < 24; m++){ 

    if (month > 11) 
    { 
     // The month has transitioned to the next year 
     month = 0; 
     ++year; 
    } 
    NSString *allMonths = [NSString stringWithFormat:@"%@ %d",[[dateFormatter monthSymbols]objectAtIndex:month], year]; 
    [monthNameArray addObject:allMonths]; 
    month++;
