Iphone 如何使用当前工作日填充UIPicker+；日期，
我正在寻找一些代码，允许我的uipicker像这样填充 我们在这里讨论两个部分。第一个组件需要日期 我能处理的第二个部件 |20日星期三下午2点 |21日星期四下午1点Iphone 如何使用当前工作日填充UIPicker+；日期，,iphone,ios4,Iphone,Ios4,我正在寻找一些代码，允许我的uipicker像这样填充 我们在这里讨论两个部分。第一个组件需要日期 我能处理的第二个部件 |20日星期三下午2点 |21日星期四下午1点 |等等 我可以处理第二个组件，只是找不到任何示例代码来格式化第一个组件。我知道我需要先确定今天，然后确定日期。。然后从那里构建，但希望有人可能有一些类似的示例代码。 任何帮助都将不胜感激 以下内容将为您提供日期名称和日期： NSDateFormatter *dateFormatter = [[NSDateFormatter al
|等等 我可以处理第二个组件，只是找不到任何示例代码来格式化第一个组件。我知道我需要先确定今天，然后确定日期。。然后从那里构建，但希望有人可能有一些类似的示例代码。
任何帮助都将不胜感激 以下内容将为您提供日期名称和日期： NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"EEEE d"]; // name of the day and day number dateString = [self.dateFormatter stringFromDate: aDate]; // Monday 20 [dateFormatter release]; NSDateFormatter*dateFormatter=[[NSDateFormatter alloc]init]； [dateFormatter setDateFormat:@“EEEE d”]；//日期名称和日期编号 dateString=[self.dateFormatter stringFromDate:aDate]；//星期一20 [日期格式化程序发布]；

因为找不到任何其他方法或更好的方法。我把这些放在一起。它正在创建一个格式化日期数组，就像我想要的那样。这并不漂亮，但我找不到更好的方法。你可能认为FOR循环会更容易设置格式化日期的最后2个字符，但事实证明这有它的怪癖，我不想花一个小时来纠正它，所以我采取了简单而丑陋的方法 下面的代码生成一个格式化的日期数组，如下所示：
星期三5日
星期四6日
星期五7日
等等……
