In your case, if value is in the beginning/end of the string you can try this:

int val = [[dpPointStr stringByTrimmingCharactersInSet:[[NSCharacterSet decimalDigitCharacterSet] invertedSet]] intValue];

int str_len = [yourStr length]; char tmp[str_len];

[NSString getCString:tmp maxLength:str_len encoding:UTF8Encoding];

int dpPoint = atoi(tmp);

Don't forget to include this: #include

I think this should work just fine.

Also, I think you can fix this by taking the intValue from the:

[verifyRow valueForKey:@"default_point"];

To be consistent with Apple use NSInteger instead, or even better NSNumber for the valueForKey statement and then NSInteger.
