我在该视图控制器中有表视图。在我的表视图中,我加载自定义单元格。在我的自定义单元格中有1个标签和1个按钮。我从FirstVC设置标签以及定制单元的按钮。见下文代码。
在FirstVC.h中
@interface FirstVC : UIViewController <UITableViewDataSource, UITableViewDelegate>
{
IBOutlet UITableView *TblView;
IBOutlet CustomCell *customCell;
}
- (void)addCounter:(NSInteger)pCat_ID;
@end
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"Cell";
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil){
[[NSBundle mainBundle] loadNibNamed:@"CustomCell_iPhone" owner:self options:nil];
cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell = categoryCustomCell;
}
NSInteger pCat_id = [[[arrayCategoryData objectAtIndex:indexPath.row] objectForKey:@"cat_id"] integerValue];
[customCell setTextForLable:@"Test"];
[customCell setAddCounterButton:pCat_id];
return cell;
}
- (void)addCounter:(NSInteger)pCat_ID
{
//Some code here….
}
在CustomCell.h中
@interface CustomCell : UITableViewCell
{
IBOutlet UILabel *lblCategoryName;
IBOutlet UIButton *btnAddCounter;
}
- (void)setTextForLable:(NSString *)cat_name;
- (void)setAddCounterButton:(NSInteger)cat_ID;
@end
CustomCell.m中的
@implementation CustomCell
- (void)setTextForLable:(NSString *)cat_name
{
lblCategoryName.text = cat_name;
}
- (void)setAddCounterButton:(NSInteger)cat_ID
{
[btnAddCounter addTarget:self action:@selector(addCounter:cat_ID) forControlEvents:UIControlEventTouchUpInside];
}
@end
我想从自定义单元格调用 addCounter:(NSInteger)pCat_ID 方法。但这个想法无法奏效。请建议我新的想法。
答案 0 :(得分:3)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *cellIdentifier = @"Cell";
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil){
[[NSBundle mainBundle] loadNibNamed:@"CustomCell_iPhone" owner:self options:nil];
cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell = categoryCustomCell;
}
NSInteger pCat_id = [[[arrayCategoryData objectAtIndex:indexPath.row]
// call your method from here.. and put your method in this file then it will work for you
[cell.btnAddCounter addTarget:self action:@selector(addCounter:pCat_id) forControlEvents:UIControlEventTouchUpInside];
return cell;
}
