Question

NSString *string=@"[e-mail]";

Now I want to delete all the characters of the string from @ which result in “test1”.
Please suggest me how to do this.
Thanks in advance!!

Answer 1

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:@"@"];
