推荐答案

我想你正在处理iPhone SDK？可能有一些其他框架使用此名称，因此您可以添加标签以包含uikit，cocoa-touch等。

I suppose you're dealing with the iPhone SDK? There may be some other frameworks which uses this name, so maybe you can add your tags to include uikit, cocoa-touch or something.

无论如何，您可以设置<$ UIPickerView实例的c $ c> showsSelectionIndicator 为NO，因此它隐藏了选择器。然后，您可以使用调整后的选择样式创建一个新视图，并将其添加到UIPickerView上方的超级视图。

Anyway, you can set showsSelectionIndicator of the UIPickerView instance to NO, so it hides the selector. Then you can create a new view with the adjusted selection style, and add it to the superview above the UIPickerView.

// Some sample code, but you can do this in IB if you want to
_pickerView = [[UIPickerView alloc] init];
_pickerView.showsSelectionIndicator = NO;
[_pickerView sizeToFit];
[self.view addSubview:_pickerView];

UIImage *selectorImage = [UIImage imageNamed:@"selectorImage.png"]; // You have to make it strechable, probably
UIView *customSelector = [[UIImageView alloc] initWithImage:selectorImage];
customSelector.frame = CGRectZero; // Whatever rect to match the UIImagePicker
[self.view addSubview:customSelector];
[customSelector release];

攻击UI元素本身需要做更多的工作，而且这也必须正常工作。

Hacking the UI Element itself will take much more work, and this has to work as well.
