iPhone和Cocoa上的日期格式

Posted 2021-02-26

iPhone uses [LDML standard](http://unicode.org/reports/tr35/tr35-4.html#DateFormatPatterns)
for date formatting

//Format Date
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat: @"yyyy-MM-dd HH:mm:ss zzz"]; // 2009-02-01 19:50:41 PST
NSString *dateString = [dateFormat stringFromDate: [scoreData objectForKey: @"date"]];
