Converting NSString to NSDate (and back again)
我在Obj-C/iOS开发阶段还是初学者...我已经创建了一个包含 NSDate * date
的类别, 我从一个 XML 文件获取数据。 所以我想做类似的事情 :
[myItem setDate:[NSDate dateWithString:xmlDate]];
我知道错误:
没有已知的选择日期类方法
最好的办法是什么?

我建议您为此使用 NSDate Formatter
实例:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// set the appropriate format in this string
[dateFormatter setDateFormat:@"EEE, d MMM yyyy HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:xmlDate];
[dateFormatter release];
您需要 < a href=" "http:// developer. apple.com/library/mac/#document/Cocoa/Reference/Foundation/Classes/Classes/NSDateFormatter_Class/Reference/Reference/Reference.html#/ apple_ref/cl/NSDateFormatter" rel= "Nept noreferrrerrrt" > NSDate Formatter . 见 < a hrefack=" https://stackoverformorm.com/ Miless/2351/Form-Drcodate_For-nsstring > > > > > > a postsution
