自定义UITableViewCell上的delete按钮

1.通过UITableViewDelegate方法可以实现删除 tableview中某一行

//滑动删除

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

{

NSUInteger row = [indexPath row];

[bookInforemoveObjectAtIndex:row];//bookInfo为当前table中显示的array

[tableView deleteRowsAtIndexPaths:[NSArrayarrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationLeft];

}

此时删除按钮为Delete，如果想显示为“删除” 中文的话，则需要实现UITableViewDelegate中的- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath方

[plain] view
plaincopy

- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{

return @"删除";

}

或者，最简单的方式，将plist中的Localization native development region改为China即可

2.这只是让默认的Delete按钮显示成了中文的删除按钮而已，如果想将这个删除按钮换成其他图片形式的，怎么办呢？

[cpp] view
plaincopy

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

static NSString *RootViewControllerCell = @"RootViewControllerCell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:RootViewControllerCell];

if(cell == nil)

{

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell]autorelease];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

[button setBackgroundImage:[UIImage imageNamed:@"delete.png"] forState:UIControlStateNormal];

[button setFrame:CGRectMake(280, 10, 30, 30)];

[button addTarget:self action:@selector(del:) forControlEvents:UIControlEventTouchUpInside];

[cell.contentView addSubview:button];

}

cell.textLabel.text = [array objectAtIndex:[indexPath row]];

cell.tag = [indexPath row];

NSArray *subviews = [cell.contentView subviews];

for(id view in subviews)

{

if([view isKindOfClass:[UIButton class]])

{

[view setTag:[indexPath row]];

[cell.contentView bringSubviewToFront:view];

}

}

return cell;

}

-(void)del:(UIButton *)button

{

NSArray *visiblecells = [self.table visibleCells];

for(UITableViewCell *cell in visiblecells)

{

if(cell.tag == button.tag)

{

[array removeObjectAtIndex:[cell tag]];

[table reloadData];

break;

}

}

}

效果如下：
