如何在objective-c中对日期进行url编码

Question

I need to url encode a date parameter so I can send it to the api.

For example if I have a date 2013-08-01 00:00:00 +0000 , I need to send this through 2013-08-01+00%3a00%3a00+%2b0000 .

How can I achieve it?

Answer 1

NSDate *myDate; // this date should be encoded
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateFormat = @"yyyy-MM-dd hh:mm:ss ZZZ";
NSString *dateString = [df stringFromDate:myDate];
NSString *encodedDate = 
  [dateString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Answer 2

这一直对我有用

NSString *encodedDate = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)dateString, NULL, (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8);
