iphone - 以所选格式获取 iPhone 上的当前时间

Question

下面应该给我一个 9:30 的 NSDate 对象:

NSString *dateString = @"09-30";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"hh-mm"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];

如何以相同的格式获取当前时间？

Answer 1

NSDate *currentTime = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"hh-mm"];
NSString *resultString = [dateFormatter stringFromDate: currentTime];
