当用户点击一个表视图(表UIButton
视图在每一行中有多个按钮)时,会显示另一个视图。在用户单击另一个 UIView 的完成按钮后,我想更改此按钮的图像。我怎样才能做到这一点?我是新手。你能为我提供一些代码吗?提前致谢。
更新代码:
表格视图代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:@"%d,%d",indexPath.section,indexPath.row];
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UIButton *market = [UIButton buttonWithType:UIButtonTypeCustom];
[market addTarget:self action:@selector(marketPressedAction:) forControlEvents:UIControlEventTouchDown];
[market setTag:3000];
[market setFrame:CGRectMake(200, 6, 30, 30)];
[cell.contentView addSubview:market];
}
for (UIButton *button in [cell subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
button.tag = indexPath.row;
[button setImage:[UIImage imageNamed:@"Marketplace.png"] forState:UIControlStateNormal];
}
}
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
_tableView.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);
return cell;
}
打开按钮的代码(用户单击以显示另一个视图的按钮)
- (void)marketPressedAction:(id)sender
{
UIButton *button = (UIButton *)sender;
buttontag = button.tag;
NSLog(@"Market button click at row %d",buttontag);
}
完成按钮的代码:
-(void)submitMarket
{
for (UIButton *button in [_tableView subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
if (button.tag == buttontag) {
[button setBackgroundImage:[UIImage imageNamed:@"MarketplaceSelect.png"] forState:UIControlStateNormal];
}
}
}
}
