int range=[string rangeOfString:@"@"].location; 
NSLog(@"%d",range); 
NSLog(@"%@",[string substringToIndex:range]);

You could use the method

- (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target 
                                        withString:(NSString *)replacement

So your code should be like below.

string = [string stringByReplacingOccurrencesOfString:@"sdk.com" withString:@""];

EDITED:

Use componentsSeparatedByString method,

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

Now your array contain exactly two component,

NSMutableString* myStringBefore = [myArray objectAtIndex:0];

if you still want @ at the end of your string ..

[myStringBefore appenString:@"@"];

 NSMutableString *string1 = [NSMutableString stringWithString: @"[email protected]"];
 NSArray* arr = [string1 componentsSeparatedByString:@"@"];
[string1 deleteCharactersInRange: [string1 rangeOfString: [NSString stringWithFormat:@"@%@",[arr objectAtIndex:1]]]];

You can use substringToIndex

string = [ string substringToIndex:5 ] ;
// If @ location is subject to change, then first find it's location index and
// pass it.
