Я использую переключатель на ячейке UITableView. Во-первых, переключатель не отмечен. Когда радио кнопка проверена. Я прокручиваю UITableView, кнопка радио не проверена. Используя этот код ниже
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 100;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
static NSString *CellIdentifierFirst = @"CellFirst";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierFirst];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease];
//cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:nil] autorelease];
}
NSArray *cellSubs = cell.contentView.subviews;
for (int i = 0 ; i < [cellSubs count] ; i++) {
[[cellSubs objectAtIndex:i] removeFromSuperview];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UIButton *redioBtn1 = [[UIButton alloc]initWithFrame:CGRectMake(20, 20, 20, 20)];
[redioBtn1 setImage:[UIImage imageNamed:@"radiounselect.png"] forState:UIControlStateNormal];
[redioBtn1 addTarget:self action:@selector(selectRadioButon:) forControlEvents:UIControlEventTouchUpInside];
redioBtn1.tag = ++tagCount;
[cell.contentView addSubview:redioBtn1];
