Sqlite database iOS application

                                     Read and write in to sqlite database in iOS application

//-----add two framework in your project---
1. libsqlite3.dylib

            }
            sqlite3_reset(statement);
        }
     }
     return nil;
  }

@end




Then go to your view controller.m and call these methods

//-----to save data in database--------
[[DBManager getSharedInstance]saveData:txtFID.text name:txtFName.text address:txtFAddress.text phone:txtFPhone.text];


//------to get data from data base------------
[[DBManager getSharedInstance]findByRegisterNumber:txtFID.text];

Making Secure TextField in iOS


Make a secure text field in iOS:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    const char * _char;
    _char = [string cStringUsingEncoding:NSUTF8StringEncoding];
    int isBackSpace = isBackSpace = strcmp(_char, "\b");

        if (range.length > 0) {
            [text deleteCharactersInRange:range];
        }
        if (range.length == 0 && range.location != 0)
        {
            NSRange backward = NSMakeRange(range.location - 1, 1);
            [text deleteCharactersInRange:backward];
        }
        
        txtPassword.text = text;
        return YES;
        
    }
    
    pass = [pass stringByAppendingString:[NSString stringWithFormat:@"%s",_char]];
    passStar = [passStar stringByAppendingString:@"*"];
