Answer 1

In general, reading the NSString documentation will answer questions like this.

For this, you can use the NSString method – stringByReplacingOccurrencesOfString:withString:

Answer 2

Assuming you have your date on a NSString object, you can do:

NSString *new = [yourDate stringByReplacingOccurrencesOfString: @"/" withString:@"-"];
