控件在 iPhone 4 上看起来不错，但在 iPhone 3GS 上看起来很糟糕，为什么？

在我的应用程序中，我有一个在当前视图上方弹出的视图，以在需要时为用户提供帮助。问题是这样的：在 iPhone 4 上，该视图的关闭按钮看起来不错，而在 iPhone 3GS 上，它上面有一个小凸起。我不知道为什么。复选框也会发生同样的情况。

这是 Picasa 相册中的图片（有 2 张图片，一张叫 iPhone 3GS，另一张叫 iPhone 4，请参阅 iPhone 3GS 图片中关闭按钮上方的凸起和复选框）。

这是用于创建关闭按钮的代码：

// Close button
    closeButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    float xCor = self.frame.size.width - kViewMargins - kCloseButtonWidth;
    float yCor = y + ((self.frame.size.height - y) / 2 - kCloseButtonHeight / 2);

    closeButton.frame = CGRectMake(xCor,
                                   yCor,
                                   kCloseButtonWidth,
                                   kCloseButtonHeight);  

    [closeButton setTitle:kClose forState:UIControlStateNormal];
    [closeButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [[closeButton titleLabel] setFont:[UIFont boldSystemFontOfSize:kQuickTipTitleFontSize]];
    [closeButton setBackgroundImage:[UIImage imageNamed:@"close_button.png"] forState:UIControlStateNormal]; 
    [closeButton addTarget:self action: @selector (doneButtonClick)  forControlEvents: UIControlEventTouchUpInside]; 
    [self addSubview:closeButton];

我不知道该怎么办，请帮忙。

谢谢，沙乌尔.

In my app, I have a view that pops above the current view to help the user if it's needed.
The problem is this: On iPhone 4, the close button of that view looks good while on iPhone 3GS it has a small bump above it. I have no idea why. Same thing happens with a checkbox.

Here are the pictures in the Picasa album (there are 2 pictures, one called iPhone 3GS and the other iPhone 4, see the bumps above the close button and the checkbox in the iPhone 3GS picture).

This is the code used to create the close button:

// Close button
    closeButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    float xCor = self.frame.size.width - kViewMargins - kCloseButtonWidth;
    float yCor = y + ((self.frame.size.height - y) / 2 - kCloseButtonHeight / 2);

    closeButton.frame = CGRectMake(xCor,
                                   yCor,
                                   kCloseButtonWidth,
                                   kCloseButtonHeight);  

    [closeButton setTitle:kClose forState:UIControlStateNormal];
    [closeButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [[closeButton titleLabel] setFont:[UIFont boldSystemFontOfSize:kQuickTipTitleFontSize]];
    [closeButton setBackgroundImage:[UIImage imageNamed:@"close_button.png"] forState:UIControlStateNormal]; 
    [closeButton addTarget:self action: @selector (doneButtonClick)  forControlEvents: UIControlEventTouchUpInside]; 
    [self addSubview:closeButton];

I don't know what to do, please help.

Thanks,
Shaul.

嗯，看起来有点像 RoundRect 默认绘图从图形后面渗出，正如乔恩所说。我建议您将按钮类型更改为 UIButtonTypeCustom，而不是弄乱您的图形：

closeButton = [UIButton buttonWithType:UIButtonTypeCustom];

这将使按钮在您设置的图形和文本之外没有任何 ui 元素。

Hmm, it looks a bit like the RoundRect default drawing is bleeding out from behind your graphic as Jon has said. Rather than messing with your graphics, I would recommend changing your button type to UIButtonTypeCustom:

closeButton = [UIButton buttonWithType:UIButtonTypeCustom];

This will make a button with NO ui elements outside of the graphic and text that you set.

我猜测是因为我看不到您的 close_button.png 文件，但我认为问题是您的 close_button.png 和您正在创建的按钮大小不同，并且您看到的凹凸是圆形的默认绘图矩形按钮。

closeButton = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage* closeImage = [UIImage imageNamed:@"close_button.png"];
float xCor = self.frame.size.width - kViewMargins - kCloseButtonWidth;
float yCor = y + ((self.frame.size.height - y) / 2 - kCloseButtonHeight / 2);
