MLPAutoCompleteTextField suggestion table interaction issue - ios

Question

Currently I'm using this third-party library in my project https://github.com/EddyBorja/MLPAutoCompleteTextField. This library is used to show the suggestion list based on user input.
I did setup the text field like this
self.searchTextField = [[MLPAutoCompleteTextField alloc] initWithFrame:CGRectMake(0, 0, 250, 30)];
[self.searchTextField setBorderStyle:UITextBorderStyleRoundedRect];
self.searchTextField.backgroundColor = [UIColor whiteColor];
self.searchTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
self.searchTextField.textColor = [UIColor blackColor];
self.searchTextField.returnKeyType = UIReturnKeyDone;
self.searchTextField.placeholder = #"Enter name to search";
self.searchTextField.autocorrectionType = UITextAutocorrectionTypeNo;
self.searchTextField.delegate = self;
self.searchTextField.autoCompleteDelegate = self;
self.searchTextField.autoCompleteDataSource = self;
Implement the Datasource protocol as below
- (NSArray *)autoCompleteTextField:(MLPAutoCompleteTextField *)textField possibleCompletionsForString:(NSString *)string {
return #[#"AAA", #"BBB", #"CCC", #"DDD"];
When I input something to the text field, the drop down list was shown but when I tap on a cell in the drop down list, the list dissappeared without completing any words in the text field.
Anyone experienced this problem please explain to me where I was wrong. Thanks in advance.

Answer 1

I had the same issue awhile back. I happened to be using MLPAutocomleteTextField inside a UITableView, so all the touch events were likely intercepted by the tableview.
I worked around this issue by setting the autoCompleteTableAppearsAsKeyboardAccessory of my MLPAutocomleteTextField instance to TRUE to enable enable autocomplete as a keyboard accessory. This allowed me to select my autocomplete options. Hopefully this solves your issue as well. :)

I solved it by subclassing my UITableViewCell, a little tricky but it's working for me:
#import "AutoCompleteTableViewCell.h"
#interface AutoCompleteTableViewCell()
#property (nonatomic, assign) BOOL selectedCell;
#end
#implementation AutoCompleteTableViewCell
- (void)awakeFromNib {
[super awakeFromNib];
self.selectedCell = NO;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent*)event
{
UIView* hitView = [super hitTest:point withEvent:event];
if (hitView != nil)
{
[self.superview bringSubviewToFront:self];
}
return hitView;
}
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent*)event
{
CGRect rect = self.bounds;
BOOL isInside = CGRectContainsPoint(rect, point);
if(!isInside)
{
for (UIView *view in self.subviews)
{
isInside = CGRectContainsPoint(view.frame, point);
if(isInside)
break;
}
}
if (!self.selectedCell) {
self.selectedCell = YES;
id view = [self superview];
while (view && [view isKindOfClass:[UITableView class]] == NO) {
view = [view superview];
}
UITableView *tableView = (UITableView *)view;
NSIndexPath *indexPath = [tableView indexPathForCell:self];
[tableView.delegate tableView:tableView didSelectRowAtIndexPath:indexPath];
}
return isInside;
}
Then delegate method is called:
- (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
didSelectAutoCompleteString:(NSString *)selectedString
withAutoCompleteObject:(id<MLPAutoCompletionObject>)selectedObject
forRowAtIndexPath:(NSIndexPath *)indexPath;
