将NSDate格式化为DDMMYYYY？

Question

我必须从日期发送DDMMYYY日期才能与API通信。

NSDateComponents * dateComponents; NSCalendar * gregorian; NSDate * date;

gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 

dateComponents = [[NSDateComponents alloc] init]; 
self.date = [gregorian dateByAddingComponents:dateComponents toDate:[NSDate date] options:0]; 

我是否必须使用[dateComponents day]等等？有没有什么方法可以帮助我像在PHP中一样执行该任务？

Answer 1

试试这个

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"ddMMyyyy"]; 
NSString *textDate = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:[NSDate date]]]; 
NSLog(@"Date %@",textDate); 
[dateFormatter release];

刚：

NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init]; 
    [outputFormatter setDateFormat:@"ddMMyyyy"]; 
    NSString *textDate = [NSString stringWithFormat:@"%@",[outputFormatter stringFromDate:[NSDate date]]]; 
    [outputFormatter release]; 

Answer 3

试试这个代码：

NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; 
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"] autorelease]]; 
[dateFormatter setDateFormat:@"ddMMyyyy"]; 
NSDate *current = [NSDate date]; 
NSString *currentstring = [dateFormatter stringFromDate:current]

只要改变你这样的代码。

NSDateFormatter *dtFormatter = [[NSDateFormatter alloc]init]; 
[dtFormatter setDateFormat:@"ddMMyyyy"];  
NSString *strDate = [NSString stringWithFormat:@"%@",[dtFormatter stringFromDate:[NSDate date]]]; 
[dtFormatter release]; 
NSLog(@"%@",strDate);
