Populate tableview with pickerview - ios

Question

I have a button, a pickerview and a tableview. When I push the button, the current selection of pickerview will be filled in the table view. Here is the code of button which pick value from pickerview
- (IBAction)addCourse:(UIButton *)sender {
NSInteger numRow=[picker selectedRowInComponent:kNumComponent];//0=1st,1=2nd,etc
NSInteger SeaRow=[picker selectedRowInComponent:kSeaComponent];//0=fall,1=spring,2=summer
NSInteger CourseRow=[picker selectedRowInComponent:kCourseComponent];
NSString *num=Number[numRow];
NSString *season=Season[SeaRow];
NSString *course=Course[CourseRow];
NSString *msgCourse=[[NSString alloc ]initWithFormat:#"%# ",course];
NSString *msgSeason=[[NSString alloc ]initWithFormat:#"%# ",season];
NSString *msgYear=[[NSString alloc ]initWithFormat:#"%# ",num];
}
Then I want to populate msgCourse,etc to my tableview
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
...Content from above msgCourse and etc
return cell;
}
How to fix the gap in my second part please? Or any example to look at please?

Answer 1

Check the following code to decide whether or not that fits into your requirements based on what I understand from your question. If it does not, please leave a comment then I will try my best to follow up.
First Step: if you have not done the delegation via storyboard, here is the first thing that you should do programatically:
-(void)ViewDidLoad
{
tableView.delegate = self;
tableView.datasource = self;
}
Second Step: I have not seen a mutablearray in your code, but I assume that you are going to make msgCourse to NSMutableArray.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// I assume you have only one section
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.msgCourse count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = nil;
cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if(!cell){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"Cell"];
}
cell.textLabel.text=[self.msgCourse objectAtIndex:indexPath.row];
return cell;
}
Last Step: By the way, do not forget to add the following line of code into your button action to reload your tableView, I assume you update the NSMutableArray and would like to refresh the tableView.
- (IBAction)addCourse:(UIButton *)sender {
.....
.....
.....
[tableView reloadData];
}
