implement tableview to show the data of database - iphone

Question

I am making a small iPhone application in which I have implemented the database concept which is used to store name, contact no, email id. I Want that whenever I user save any contact It get displayed on table view. In -(IBAction)retriveall:(id)sender action I am retriving all the data from database and storing it into array. Now I want to display all the data in tableview.
How can I do this? Please help me.
-(IBAction)retriveall:(id)sender
{
[self retrive2];
for (int i =0; i< [namearray count]; i++)
{
NSLog(#"Name is:%#",[namearray objectAtIndex:i]);
NSLog(#"Password is:%#",[passarray objectAtIndex:i]);
}
}
-(IBAction)retrive:(id)sender
{
[self retrive1];
two.text = databasecolorvalue;
UIAlertView *favAlert=[[UIAlertView alloc] initWithTitle:#"" message:#"Retrived" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[favAlert show];
[favAlert release];
}
-(void)retrive1
{
databaseName = #"med.sqlite";
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
#try {
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {
const char *sqlStatement="select pswd from Login where username = ? ";
sqlite3_stmt *compiledStatement;
if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
// Loop through the results and add them to the feeds array
// Create a new animal object with the data from the database
sqlite3_bind_text(compiledStatement, 1, [one.text UTF8String], -1, SQLITE_TRANSIENT);
while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
databasecolorvalue =[NSString stringWithUTF8String:(char*)sqlite3_column_text(compiledStatement,0)];
}
}
// Release the compiled statement from memory
sqlite3_finalize(compiledStatement);
}
sqlite3_close(database);
}
#catch (NSException * ex) {
#throw ex;
}
#finally {
}
}

Answer 1

You should declare an mutable array as an instance variable something like,
NSMutableArray * colors;
Initialize it in the viewDidLoad method and later alter your retrive1 method to add to the colors array.
-(void)retrive1
{
/* Clearing existing values for newer ones */
[colors removeAllObjects]
/* Get database path */
#try {
[..]
while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
[colors addObject:[NSString stringWithUTF8String:(char*)sqlite3_column_text(compiledStatement,0)]];
}
[..]
}
#catch (NSException * ex) { #throw ex; }
#finally { }
}
And you'll have to implement the rest of the table view methods in the usual manner using the array as the source.

Answer 2

You have to create object with all data and implementation of UITableViewDataSource protocol for table view and set it in TableView property dataSource. After you havecall UITableView method
-(void)reloadData;
