How to spliit a NSString in iOS

Question

I have a NSString like this.

00:03:45

I want to get only this 03:45 part and show in a UILabel

How can I do that? Please help me

Thanks

You could start by actually reading the documentation for NSString. — Hot Licks, Mar 07 '15 at 04:42
Agreed. Apple's documentation is good enough for most situation. — ljk321, Mar 07 '15 at 04:45

NSArray *timeParts = [string componentsSeparatedByString: @":"];

NSString *newTime = [NSString stringWithFormat:@"%@/%@", [timeParts objectAtIndex:1], [timeParts objectAtIndex:2]];

Don't think in terms of splitting a string, think in terms of formatting your date that happens to be a string. You'll want to use an NSDateFormatter here.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"mm:ss"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0.0]];//Or whatever is applicable for your
NSString *timeString = [self.dateFormatter dateFromString:[NSDate dateFromString:yourString];

Or, if you really wanted to get a substring from that particular string, you could do this:

NSString *subString = [yourString substringWithRange:NSMakeRange(3, 7)];

you can do this multiple types

assume that this is your String

NSString *origialString =@"00:03:45";

Type-1

NSArray *getBalance = [origialString componentsSeparatedByString: @":"];

origialString = [NSString stringWithFormat:@"%@:%@", [getBalance objectAtIndex:1], [getBalance objectAtIndex:2]];

Type-2

origialString = [origialString substringFromIndex:3];

Type-3

origialString = [origialString substringWithRange:NSMakeRange(3, [origialString  length]-3)];

Type-4

// Use NSDateformatter but not necessary for here
