objective-c – Escape NSDateFormatter String

如何从NSDateFormatter格式转义字符？

NSDate *currentDate = [NSDate date];
NSDateFormatter *dateFormater = [[NSDateFormatter alloc] init];
[dateFormater setDateFormat:@"dd/MM/yyyy \\a\\t HH:mm"];
Nsstring *dateFormated = [dateFormater stringFromDate:currentDate];

NSLog(@"%@",dateFormated);

解决方法

您可以通过将其包含在单引号中来转义文本：

[dateFormater setDateFormat:@"dd/MM/yyyy 'at' HH:mm"];

从docs：

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd 'at' HH:mm"];   
NSDate *date = [NSDate dateWithTimeIntervalSinceReferenceDate:162000];   
Nsstring *formattedDateString = [dateFormatter stringFromDate:date];   
NSLog(@"formattedDateString: %@",formattedDateString); 
// For US English,the output may be: 
// formattedDateString: 2001-01-02 at 13:00
