Question

I am stuck.
Is there any function which can import CSV records directly to sqlite table ?
Any help will be appreciable.

Answer 1

Here is a rough code to do that. Please do some changes as per your requirement.

-(void)loadCSVData{
    
    
    NSStringEncoding encoding;
    NSString *path1=[[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:filename ofType:@"csv"]  usedEncoding:&encoding error:nil];
//You will get the array of lines
    NSArray *messArr=[path1 componentsSeparatedByString:@"\n"]; 

//Now start to process each single line.
   if(messArr)
   {
       for(int i=0;i<=[messArr count]-1;i++)
       {
           
           NSMutableDictionary *d=[[NSMutableDictionary alloc] init];
           NSString *StrValue=[NSString stringWithFormat:@"%@",[messArr objectAtIndex:i]];
           StrValue=[StrValue stringByReplacingOccurrencesOfString:@"\"" withString:@""];
           StrValue=[StrValue stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
           NSArray *arr=[StrValue componentsSeparatedByString:@","];

/*Add value for each column into dictionary*/


           [d setValue:[arr objectAtIndex:0] forKey:@"columnName"];
           
//Add this dictionary "d" into database

[d release]; //Cleanup.
       }
   }
[path1 release];
   
}

Please also refer the following question's answers. There is a nice explanation of creating your own custom CSV parser.
