iWatch 的布局，与手机的APP的布局不同，如果不用WKInterfaceGroup,一行只能布局一个控件，与HTML几分相似。好了不废话，先讲述WKInterfaceGroup，再讲述UIStoryBoard的用法。因为WKInterfaceGroup对UIStoryBoard布局起到十分大作用，WKInterfaceGroup里面进行一行多个控件布局。

1. WKInterfaceGroup

1.1 WKInterfaceGroup方法

@interface WKInterfaceGroup : WKInterfaceObject <WKImageAnimatable>

//设置cornerRadius圆角
- (void)setCornerRadius:(CGFloat)cornerRadius;

//设置内置的间距
- (void)setContentInset:(UIEdgeInsets)contentInset;

//设置背景颜色
- (void)setBackgroundColor:(nullable UIColor *)color;

//设置背景图片
- (void)setBackgroundImage:(nullable UIImage *)image;

//设置背景图片，用网络加载
- (void)setBackgroundImageData:(nullable NSData *)imageData;

//设置背景图片，用图片名字
- (void)setBackgroundImageNamed:(nullable NSString *)imageName;

@end

1.2 WKInterfaceGroup用法

@interface InterfaceController()
//从storyBoard中拖的 控件
@property (unsafe_unretained, nonatomic) IBOutlet WKInterfaceGroup *group;

@end


@implementation InterfaceController

- (void)awakeWithContext:(id)context {
    
    [super awakeWithContext:context];
    
    //设置圆角
    [self.group setCornerRadius:20];
    
    //设置背影颜色
    [self.group setBackgroundColor:[UIColor redColor]];
    
    //设置内置间距
    [self.group setContentInset:UIEdgeInsetsMake(20, 20, 20, 20)];

    //设置背景图片
    [self.group setBackgroundImageNamed:@"Personal communication"];
}

- (void)willActivate {
    // This method is called when watch view controller is about to be visible to user
    [super willActivate];
    
    
}

- (void)didDeactivate {
    // This method is called when watch view controller is no longer visible
    [super didDeactivate];
}

@end
