WKInterfaceLabel使用
WKInterfaceLabel 类似iOS 组件中的UILabel, 可通过使用 setText 的方式来设置具体的值,这里就不做多阐述。
WKInterfaceImage 使用
WKInterfaceImage 类似于 UIImageView, 使用时,可用setImage 来设置图片。它的接口如下:
@class UIImage; @protocol WKImageAnimatable <NSObject> // Play all images repeatedly using duration specified in interface description. - (void)startAnimating; // Play a subset of images for a certain number of times. 0 means repeat until stop. - (void)startAnimatingWithImagesInRange:(NSRange)imageRange duration:(NSTimeInterval)duration repeatCount:(NSInteger)repeatCount; - (void)stopAnimating; @end WK_CLASS_AVAILABLE_IOS(8_2) @interface WKInterfaceImage : WKInterfaceObject <WKImageAnimatable> - (void)setImage:(nullable UIImage *)image; - (void)setImageData:(nullable NSData *)imageData; - (void)setImageNamed:(nullable NSString *)imageName; - (void)setTintColor:(nullable UIColor *)tintColor; @end NS_ASSUME_NONNULL_ENDWKInterfaceTable
相比于iOS 中的UITableViewController来说,iwatch中的WKInterfaceTable功能就简单多了,它没有delegate 也无需设置数据源。
在组件库中选中WKInterfaceTable 拖入Interface.storyboard中,并在代码中形成对应的关联,这里有一点要注意一下,那就是这个必须要设置 Row Controller 的identifier, 不然数据就无法加载出来。
在这里就使用静态的数据让这个Table 控件来加载出来, 代码如下:
NSMutableDictionary *phoneContact = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"13776054770", @"约翰", @"13776054770", @"约翰1", @"13776054771", @"约翰2", @"13776054772", @"约翰3", @"13776054773", @"约翰4", nil]; [_contactTableV setNumberOfRows:phoneContact.count withRowType:@"MyTableRowControl"]; NSArray *namesArray = phoneContact.allKeys; for(int i = 0; i < phoneContact.count; i++){ NSString *name = [namesArray objectAtIndex:i]; NSString *phone = [phoneContact objectForKey:name]; MyTableRowControl *row = [_contactTableV rowControllerAtIndex:i]; [row.contactName setText:name]; [row.phoneNo setText:phone]; }table点击事件,通过重写实现InterfaceController 来处理:
- (void)table:(WKInterfaceTable *)table didSelectRowAtIndex:(NSInteger)rowIndex{ NSLog(@"我点击了 %ld 行", (long)rowIndex); }WKInterfaceButton
iWatch 按钮控件,可用的API 如下:
NS_ASSUME_NONNULL_BEGIN @class UIImage, UIColor; WK_CLASS_AVAILABLE_IOS(8_2) @interface WKInterfaceButton : WKInterfaceObject - (void)setTitle:(nullable NSString *)title; - (void)setAttributedTitle:(nullable NSAttributedString *)attributedTitle; - (void)setBackgroundColor:(nullable UIColor *)color; - (void)setBackgroundImage:(nullable UIImage *)image; - (void)setBackgroundImageData:(nullable NSData *)imageData; - (void)setBackgroundImageNamed:(nullable NSString *)imageName; - (void)setEnabled:(BOOL)enabled; @end NS_ASSUME_NONNULL_END按钮点击事件,可以通过storyboard 拖拽的方式来实现,也可通过代码来实现。
WKInterfaceDate
日期控件,可用API 如下:
NS_ASSUME_NONNULL_BEGIN @class UIColor; WK_CLASS_AVAILABLE_IOS(8_2) @interface WKInterfaceDate : WKInterfaceObject - (void)setTextColor:(nullable UIColor *)color; - (void)setTimeZone:(nullable NSTimeZone *)timeZone; - (void)setCalendar:(nullable NSCalendar *)calendar; @end NS_ASSUME_NONNULL_ENDWKInterfaceTimer
时间控件, 可用 API 如下:
NS_ASSUME_NONNULL_BEGIN @class UIColor; WK_CLASS_AVAILABLE_IOS(8_2) @interface WKInterfaceTimer : WKInterfaceObject - (void)setTextColor:(nullable UIColor *)color; - (void)setDate:(NSDate *)date; // count up/down from current date to this date - (void)start; - (void)stop; @end NS_ASSUME_NONNULL_END好了。祝大家生活愉快。多多收获友谊和爱情。如果想获取更多的讯息,请扫描下方二维码关注我的微信公众号:
