Here's an example how to create your own class that acts similar to alert view, but you can put any background/button graphics you want:
这是一个如何创建自己的类的示例，该类的行为类似于警报视图，但您可以放置所需的任何背景/按钮图形：

Create custom view in ReturnAlert.xib
在 ReturnAlert.xib 中创建自定义视图
class ReturnView: UIView, UITextFieldDelegate {
}
class ReturnAlert: UIAlertController {
var returnView: ReturnView?
public convenience init(id message: String?) {
self.init(title: nil, message: "message", preferredStyle: .alert)
guard let view = UINib(nibName: "ReturnAlert", bundle: Bundle(for: ReturnView.self)).instantiate(withOwner: ReturnView.self, options: nil)[0] as? ReturnView else{
fatalError("Return view not found")
}
self.returnView = view
view.alert = self
let parent = self.view.subviews[0].subviews[0]
for sv in parent.subviews {
sv.removeFromSuperview()
}
view.bounds = CGRect(x: parent.bounds.origin.x, y: parent.bounds.origin.y, width: view.frame.size.width, height: view.frame.size.height)
parent.addSubview(view)
let xConstraint = NSLayoutConstraint(item: view, attribute: .centerX, relatedBy: .equal, toItem: parent, attribute: .centerX, multiplier: 1, constant: 0)
let yConstraint = NSLayoutConstraint(item: view, attribute: .centerY, relatedBy: .equal, toItem: parent, attribute: .centerY, multiplier: 1, constant: 0)
parent.addConstraint(xConstraint)
parent.addConstraint(yConstraint)
}
}

- (void)willPresentAlertView:(UIAlertView *)alertView;
- (void)didPresentAlertView:(UIAlertView *)alertView;
in any of the above message, check the subviews and their class and change the values as you desire. see this sample code for UIActionSheet. search for classes of all components using ns log and customize your desire class. This is uiactionsheet code
在上述任何消息中，检查子视图及其类并根据需要更改值。请参阅 UIActionSheet 的示例代码。使用 ns log 搜索所有组件的类并自定义您想要的类。这是uiactionsheet代码
for (UIView* view in [actionSheet subviews])
{
NSLog(@"%@",[view class]);
if ([[[view class] description] isEqualToString:@"UIAlertButton"] && [view respondsToSelector:@selector(setAlpha:)])
{
[view setAlpha:2.0];
[view setOpaque:YES];
if ([view respondsToSelector:@selector(title)])
{
NSString* title = [view performSelector:@selector(title)];
if ([title isEqualToString:@"Cancel"] && [view respondsToSelector:@selector(setBackgroundImage:forState:)] && [view respondsToSelector:@selector(setFrame:)] && [view respondsToSelector:@selector(setFrame:)] && [view respondsToSelector:@selector(setTitleColor:forState:)])
{
[view setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[view setBackgroundImage:[UIImage imageNamed:@"btn-cancel.png"] forState:UIControlStateNormal];
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y+10, view.frame.size.width,view.frame.size.height)];
}
}
}
}
