How to extract cell value/text from UITableView? - ios

Question

For some reasons, I have to extract a cell's text or value from a UITableView. I have the following table method:
- (void)loadCollection_Information
{
_collection_InformationCellData = [[NSMutableArray alloc] init];
NSMutableArray *cells_1 = [[NSMutableArray alloc] init];
NSDictionary *cellContainer_1_1 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"Brett Whiteley", #"Author", #"", #"", #"", #"", nil] forKeys:[NSArray arrayWithObjects:#"Text", #"Detail Text", #"Image", #"Text Color", #"Detail Text Color", #"Accessory", nil]];
[cells_1 addObject:cellContainer_1_1];
NSDictionary *cellContainer_1_2 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"1976", #"Year", #"", #"", #"", #"", nil]
forKeys:[NSArray arrayWithObjects:#"Text", #"Detail Text", #"Image", #"Text Color", #"Detail Text Color", #"Accessory", nil]];
[cells_1 addObject:cellContainer_1_2];
NSDictionary *cellContainer_1_3 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"Canvas, Oil", #"Materials", #"", #"", #"", #"", nil] forKeys:[NSArray arrayWithObjects:#"Text", #"Detail Text", #"Image", #"Text Color", #"Detail Text Color", #"Accessory", nil]];
[cells_1 addObject:cellContainer_1_3];
NSDictionary *cellContainer_1_4 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"Social Comment & Hard Edged Abstraction", #"Style", #"", #"", #"", #"", nil]
forKeys:[NSArray arrayWithObjects:#"Text", #"Detail Text", #"Image", #"Text Color", #"Detail Text Color", #"Accessory", nil]];
[cells_1 addObject:cellContainer_1_4];
NSDictionary *cellContainer_1_5 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"182.0 high * 200.0 wide cm", #"Size", #"", #"", #"", #"", nil]
forKeys:[NSArray arrayWithObjects:#"Text", #"Detail Text", #"Image", #"Text Color", #"Detail Text Color", #"Accessory", nil]];
[cells_1 addObject:cellContainer_1_5];
NSDictionary *sectionContainer_1 = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:#"Collection Information", cells_1, #"", nil]
forKeys:[NSArray arrayWithObjects:#"Title", #"Cells", #"Footer Title", nil]];
[_collection_InformationCellData addObject:sectionContainer_1];
_collection_InformationSelectedRow = 0;
_collection_InformationSelectedSection = 0;
_collection_InformationShowHeader = YES;
[_collection_Information setEditing:NO];
[_collection_Information reloadData];
}
and didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if (tableView == _collection_Information) {
if (indexPath.section == 0 && indexPath.row == 0) {
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"Brett_WhiteleyViewController"];
[self.navigationController pushViewController:controller animated:YES];
}
if (indexPath.section == 0 && indexPath.row == 1) {
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"Year_1960s_70sViewController"];
[self.navigationController pushViewController:controller animated:YES];
}
if (indexPath.section == 0 && indexPath.row == 2) {
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"Canvas_and_OilViewController"];
[self.navigationController pushViewController:controller animated:YES];
}
if (indexPath.section == 0 && indexPath.row == 3) {
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"SC_and_HE_AbstractionViewController"];
[self.navigationController pushViewController:controller animated:YES];
}
}
//Get the Dictionary Object at index 0, to check out the object.
NSLog(#"%#",[_collection_InformationCellData objectAtIndex:0]);
//Store the Objects from dictionary in temp Array.
NSArray *temp = [[_collection_InformationCellData objectAtIndex:indexPath.section] valueForKey:#"Cells"];
//Get the object based on Row Selection in UITableView.
NSLog(#"%#",[[temp objectAtIndex: indexPath.row] valueForKey:#"Text"]);
}
I need to extract the NSStrings such as: Brett Whiteley, 1976, Canvas, Oil, Social Comment & Hard Edged Abstraction separately, and put it into follow code in another method:
-(NSString *)maxmsg
{
NSString *msg;
int maxint=-1;
RecommendationData *obj = [RecommendationData getInstance];
if(obj.author<=5 && obj.year<=5 && obj.material<=5 && obj.style<=5)
{
msg=#"nothing";
}
else if( obj.author >= obj.year && obj.author >= obj.material && obj.author >= obj.style)
{
maxint=obj.author;
//the code for placing the value
obj.maxValue= (place value here);
msg=#"It seems that you are interested in the author of this collection.";
}
else if(obj.year >= obj.author && obj.year >= obj.material && obj.year >= obj.style)
{
maxint=obj.year;
//the code for placing the value
obj.maxValue= (place value here);
msg=#"It seems that you are interested in this period of the collection.";
}
else
{
msg=#"equal";
}
return msg;
}
Can anyone tell me how to do it?

Answer 1

To receive "Brett Whiteley" from another method you can call
_collection_InformationCellData[ CellContainerIndex ][ #"Cells" ][ 0 ][ "Text" ]
but you need to save somewhere/to know the correct CellContainerIndex. May be it is just 0 in your case?

Answer 2

Here is the way to perform it :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Get the Dictionary Object at index 0, to check out the object.
NSLog(#"%#",[_collection_InformationCellData objectAtIndex:0]);
//Store the Objects from dictionary in temp Array.
NSArray *temp = [[_collection_InformationCellData objectAtIndex:indexPath.section] valueForKey:#"Cells"];
//Get the object based on Row Selection in UITableView.
NSLog(#"%#",[[temp objectAtIndex: indexPath.row] valueForKey:#"Text"]);
}
You need to access the Array using Index and getting the values using key from that object.
