Question

I am having a string as follows

NSString str1 = @"Hello your bal = 68094";

and I want to remove all characters after “=” symbol encounters in string.

Can any one give me the solution for this?

Answer 1

Try the following solution:

NSString *str1 = @"Hello your bal = 68094";
NSRange range = [str1 rangeOfString:@"="];
if (range.location != NSNotFound) {
    NSString *newString = [str1 substringToIndex:range.location];
    NSLog(@"%@",newString);
} else {
    NSLog(@"= is not found");
}

or

NSString *str1 = @"Hello your bal = 68094";
NSRange range = [str1 rangeOfString:@"="];
if (range.location != NSNotFound) {
    NSString *newString = [str1 substringWithRange:NSMakeRange(0, range.location)];
    NSLog(@"%@",newString);
} else {
    NSLog(@"= is not found");
}

Update for @geekay_gk:
If you are sure that you would have 2 “=” in your string, then

NSString *str1=@"Hello your balance = 60094 and your id = rt456";
NSRange range = [str1 rangeOfString:@"=" options: NSBackwardsSearch];
NSString *newString = [str1 substringFromIndex:(range.location+1)];
NSLog(@"%@",newString);

If it contains whitespace, it would be better to trim the string.
