I am creating a today extension for my app, but there are some errors that I can't quite understand:
First: Everything is Ok on the storyboard, but the button doesn't appear on the widget.
Second: When the tableview has more than one cell, the last cell gets cut.
Third: CellForRow is called, but don't change anything on the cell (Label is still "Label").

Here's my Widget code:
@implementation TodayViewController{
NSMutableArray *listaFavoritos;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.widgetTableView.delegate = self;
self.widgetTableView.dataSource = self;
[self updateTableView];
self.preferredContentSize = self.widgetTableView.frame.size;
}
- (void)widgetPerformUpdateWithCompletionHandler:(void (^)(NCUpdateResult))completionHandler {
// Perform any setup necessary in order to update the view.
// If an error is encountered, use NCUpdateResultFailed
// If there's no update required, use NCUpdateResultNoData
// If there's an update, use NCUpdateResultNewData
completionHandler(NCUpdateResultNewData);
}
- (id)initWithCoder:(NSCoder *)aDecoder {
if (self = [super initWithCoder:aDecoder]) {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(userDefaultsDidChange:)
name:NSUserDefaultsDidChangeNotification
object:nil];
}
return self;
}
- (void)userDefaultsDidChange:(NSNotification *)notification {
[self updateTableView];
}
- (void)updateTableView {
listaFavoritos = [[NSMutableArray alloc] init];
//listaFavoritos = [[self readArrayWithCustomObjFromUserDefaults:@"listaFavs"] mutableCopy];
[listaFavoritos addObject:@"test1"];
[listaFavoritos addObject:@"test2"];
NSLog(@"%@", listaFavoritos);
}
-(NSArray *)readArrayWithCustomObjFromUserDefaults:(NSString*)keyName
{
NSUserDefaults *sharedDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.kazoowa.timers"];
NSData *data = [sharedDefaults objectForKey:keyName];
NSArray *myArray = [NSKeyedUnarchiver unarchiveObjectWithData:data];
[sharedDefaults synchronize];
return myArray;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [listaFavoritos count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
WidgetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"WidgetCell" forIndexPath:indexPath];
if (cell == nil)
{
cell.nomeTimer.text = [listaFavoritos objectAtIndex:indexPath.row];
}
NSLog(@"CellForRow");
return cell;
}
1)For your second problem, your cellIdentifier in tableView:cellForRowAtIndexPath will be "static" like this :
static NSString *cellName = @"WidgetCell";
WidgetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellName forIndexPath:indexPath];
2)this condition will be never execute because it's never nil :
if (cell == nil)
{
cell.nomeTimer.text = [listaFavoritos objectAtIndex:indexPath.row];
}
replace it by this :
if (cell != nil)
{
cell.nomeTimer.text = [listaFavoritos objectAtIndex:indexPath.row];
}
3)Please use Pragma Mark for separate properly your code like below:
#pragma mark-UITableViewDataSource
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [listaFavoritos count];
}
#pragma mark-UITableViewDelegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
WidgetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"WidgetCell" forIndexPath:indexPath];
if (cell == nil)
{
cell.nomeTimer.text = [listaFavoritos objectAtIndex:indexPath.row];
}
NSLog(@"CellForRow");
return cell;
}
Hope it helps :)
Try it :
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellName = @"WidgetCell";
WidgetTableViewCell *cell = (WidgetTableViewCell *)[theTableView dequeueReusableCellWithIdentifier:cellName];
if (cell == nil) {
cell = [[WidgetTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellName];
}
cell.textLabel.text = [listaFavoritos objectAtIndex:indexPath.row];;
return cell;
