如何将的initWithDevice函数改写为MyViewControllerB转换为Swift 3？将Obj-C初始化覆盖函数转换为Swift 3

MyViewControllerA

@interface MyViewControllerA : UIViewController 
- (instancetype)initWithDevice:(DeviceClass *)device; 
@end 

@implementation MyViewControllerA 
- (instancetype)initWithDevice:(DeviceClass *)device 
{ 
    self = [super init]; 
    if (self) { 
     // set a bunch of properties 
    } 
    return self; 
} 
@end

MyViewControllerB

@interface MyViewControllerB : MyViewControllerA 
    - (instancetype)initWithDevice:(DeviceClass *)device; 
@end 

@implementation MyViewControllerB 
- (instancetype)initWithDevice:(DeviceClass *)device 
{ 
    if (self = [super initWithNibName:@"AnotherViewController" bundle:nil]) { 
     // init stuff for subclass 
    } 
    return self; 
} 
@end

谢谢，伙计们！漂亮的工具。 @AntonyRaphel - 我也不得不增加以下内容：所需的init（编码器aDecoder：NSCoder）{ super.init（编码器：aDecoder） } 如果你想发布的解决方案，我会接受？谢谢！ – Vee

为夫特3.0和夫特2.2

override init(device: DeviceClass) { 
super.init(nibName: "AnotherViewController", bundle: nil) 

// init stuff for subclass 

} 

required init?(coder aDecoder: NSCoder){ 
    super.init(coder: aDecoder) 
}

您可以与您Objective-C的代码试图进入斯威夫特通过使用此网站也：objectivec2swift
