解决方法
这就是
NSDateComponentsFormatter所做的.来自文档的一个例子：
NSDateComponentsFormatter* formatter = [[NSDateComponentsFormatter alloc] init]; formatter.unitsStyle = NSDateComponentsFormatterUnitsStyleFull; formatter.includesApproximationPhrase = YES; formatter.includesTimeRemainingPhrase = YES; formatter.allowedUnits = NSCalendarUnitMinute; // Use the configured formatter to generate the string. NSString* outputString = [formatter stringFromTimeInterval:300.0];
给出“剩余约5分钟”.
