Here, I sorted out a more convenient method. The idea is to set an identifier for the cell, isSpread, expanded or unexpanded, set the height of the cell to 200, and set the height of the unexpanded cell to 100. By changing the identifier and refreshing the height of the cell, the effect of expanding and shrinking the cell can be achieved
– (CGFloat)tableView:(UITableView*)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath{
// Cell expansion 20160606
ArewDataModle*modle =self.sectionDataArr3[indexPath.row];
if(modle.isSpread==NO) {
return55;
}else{
return100;
}
}
// Key code in CellForRow
– (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{
cell.spreadImage.hidden=NO;
if(self.sectionDataArr3[indexPath.row].isSpread==NO)
{
}else{
cell.additionalLabel.hidden=NO;
}
UITapGestureRecognizer*tapSpreadImage = [[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(SpreadImageClick:)];
// Pass the current gesture
tapSpreadImage.delegate=self;
[cell.spreadImageaddGestureRecognizer:tapSpreadImage];
}
– (void)SpreadImageClick:(UITapGestureRecognizer*)tap{
// Pass the current gesture to identify the clicked cell
ArewTableViewCell* cell = (ArewTableViewCell*)tap.view.superview.superview;
NSIndexPath*indexpath = [self.brewTimeTableindexPathForCell:cell];
// Cell expansion
ArewDataModle*modle =self.sectionDataArr3[indexpath.row];
modle.isSpread= ! modle.isSpread;
cell.additionalLabel.hidden= ! self.isSpreadImage;
[self.ArewTimeTablereloadRowsAtIndexPaths:[NSArrayarrayWithObjects:indexpath,nil]withRowAnimation:UITableViewRowAnimatio nNone];
}
There is another way to add a self-defined cell under the current cell when you click a cell on the network, focusing on processing the data source array
This code is sorted out online.
