Question

我用UIButton在我的UITableViewCell内,可以选择这个 but子,选择金星和未经选择的光球。

“entergraph

The problem is that when ever the cell is selected, no matter if the button is selected or not it will turn to a gray color (this gray color is different than the gray color of unselected mode of the star). I ve been trying to figure out why this happens, but had no luck.

“entergraph

here is the implementation of the cells,

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

UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];    
UIButton *button = [[UIButton buttonWithType:UIButtonTypeCustom]retain];

//set the background of the cells
cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed: @"cellBackground.png"]];
cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cellselected2.png"]];

// set the button content
[button setImage:[UIImage imageNamed:@"star.png" ] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"starSelected.png"] forState:UIControlStateSelected];
[button addTarget:self action:@selector(selectedButton:) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(280, 10,  24, 24)];

[cell addSubview:button];

return cell;
}

也是当我主在选定牢房时的纽顿将彻底消失!

Answer 1

我描述了问题。问题是,当单元被选定时,牢房中的UIButton将去“亮度状态”。如果在纽特州没有被分配使用的形象,那么它就会发现与我的情况一样。

因此,我只是通过在UIButton着重指出的州增加我喜欢使用的图像而确定,

[button setImage:[UIImage imageNamed:@"starSelected.png"] forState:UIControlStateHighlighted];

希望有助于面临同样问题的其他人:

Answer 2

你们正在将ton子添加到囚室框架中,而不是其内容。观点。

UITableViewCell adds the value of this property as a subview only when the cell is selected. It adds the selected background view as a subview directly above the background view (backgroundView) if it is not nil, or behind all other views. Whilest a UITableViewCell adds the background view as a subview behind all other views and uses its current frame location.

替换

[cell addSubview:favButton];

iii

[cell.contentView addSubview:favButton];

这一点应当解决。

便携式电文Cell物体的内容观点是该电池显示的内容的缺省表面。如果你想通过简单地增加其他观点来定制电池,那么你就应当把电池添加到内容观点中,以便随着电池向编辑方式过渡和从编辑方式过渡,能够适当定位。

You can certainly set the image for the highlighted state. Another option, if you want to use the same image for UIControlStateNormal and UIControlStateHighlighted you can also say button.adjustsImageWhenHighlighted = NO, the default is YES.
