UITableView inside a view controller - ios

Question

This is my View Controller, as you can see, there is a UITableView in the lower part.
I put the delegate and datasource in the .h file
#interface CourseFindrViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
While my .m file is this:
#interface CourseFindrViewController ()
{ sqlite3 *_db;}
#property (nonatomic, weak) IBOutlet UILabel *jNameLabel;
#property (weak, nonatomic) IBOutlet UITextView *jDescLabel;
#property (nonatomic, weak) IBOutlet UILabel *jEarningsLabel;
#property (weak, nonatomic) IBOutlet UITableView *cTableLabel;
#end
#implementation CourseFindrViewController
#synthesize jDetails =_jDetails;
-(void)viewWillAppear:(BOOL)animated {
_jDetails = (Jobs *)self.jDetails;
[self.jNameLabel setText:_jDetails.jName];
[self.jDescLabel setText:_jDetails.jDesc];
[self.jEarningsLabel setText:_jDetails.jEarnings];
NSLog(#"%d", _jDetails.jID);
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.jNameLabel = nil;
self.jDescLabel = nil;
self.jEarningsLabel = nil;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(NSArray *)course;
{
NSString *sqLiteDb = [[NSBundle mainBundle]pathForResource:#"CourseFindr" ofType:#"sqlite"];
sqlite3_stmt *statement;
NSMutableArray *retrieve = [[NSMutableArray alloc] init];
if (sqlite3_open([sqLiteDb UTF8String], &_db) != SQLITE_OK)
{
NSString *query= [NSString stringWithFormat:#"SELECT course. * FROM course INNER JOIN jobsCourse ON jobsCourse.courseID = course.cID WHERE jobsCourse.jobID = %d", _jDetails.jID];
if (sqlite3_prepare_v2(_db, [query UTF8String], -1, &statement, nil) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
int _cID = sqlite3_column_int(statement, 0);
char *cNameChars = (char *) sqlite3_column_text(statement,1);
char *cDescChars = (char *) sqlite3_column_text(statement, 2);
char *cSchoolChars = (char *) sqlite3_column_text (statement, 3);
char *cProgramChars = (char *) sqlite3_column_text(statement, 4);
NSString *_cName =cNameChars?[[NSString alloc]initWithUTF8String:cNameChars]:#"";
NSString *_cDesc = cDescChars?[[NSString alloc]initWithUTF8String:cDescChars]:#"";
NSString *_cSchool = cSchoolChars?[[NSString alloc]initWithUTF8String:cSchoolChars]:#"";
NSString *_cProgram = cProgramChars?[[NSString alloc]initWithUTF8String:cProgramChars]:#"";
Course *courses = [[Course alloc]
initWithCID:_cID
cName:_cName
cDesc:_cDesc
cSchool:_cSchool
cProgram:_cProgram];
[retrieve addObject:courses];
}
sqlite3_finalize(statement);
}
}
return retrieve;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *title1 = _jDetails.jName;
self.navigationItem.title = title1;
}
- (void)dealloc {
}
The code stops here. I added a breakpoint.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.course count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"courseCell"];
NSLog(#"Here.");
Course *courses = [self.course objectAtIndex:indexPath.row];
cell.textLabel.text =courses.cName;
cell.detailTextLabel.text =courses.cSchool;
return cell;
}
And it's still not passing the data to the table.. the table isn't appearing.

Answer 1

You have to add connection between table view and your datasource and delegate.
To do that simple control drag from your table view to view controller and select datasource and do the same but this time select delegate.

Answer 2

You must connect datasource and delegate in the xib. Plese let me know if this answer helped you.
