Question

我正在创建一个程序, 当前的日期需要在一个标签中显示, 并且每天自动更新。我查看了几个教义, 他们都展示了如何在 YYYY: DD: MM hh: mm 中获取日期, 我想知道如何将格式修改为 DD/ MM/ YYYY 。

如有任何样本代码或与教程的链接,将不胜感激。

Answer 1

像这样的事情:

NSDate          *today     = [NSDate date];
NSDateFormatter *formatter = [[NSDateformatter alloc] init];

[formatter setDateFormat:@"dd/MMM/yyyy"];
[myLabel   setText:[formatter stringFromDate:today]];

Answer 2

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: @"dd/MM/yyyy"];

NSString *dateString = [dateFormatter stringFromDate: dayDate];

//display dateString in label

[dateFormatter release];

Answer 3

You need to use the NSDateFormatter. For specfic formats look at https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSDateFormatter_Class/Reference/Reference.html

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"dd/MMM/yyyy"];

NSDate *now = [[NSDate alloc] init];

NSString *dateString = [format stringFromDate:now];
