我想創建一個應用程序,我可以從蘋果手錶發送信息到我的ios父應用程序。我爲它編寫了代碼,但是當我運行WatchConnectivity應用程序時,信息不會在Apple Watch和父級ios應用程序之間傳輸。這可能是我的代碼有問題,也可能是因爲某些原因,手錶不能從應用程序啓動。我必須去模擬器並點擊應用程序才能開始。這是爲什麼我的代碼不工作?手錶連接不工作
InterfaceController.m
#import "InterfaceController.h"
#import <WatchConnectivity/WatchConnectivity.h>
@interface InterfaceController() <WCSessionDelegate>
@property (strong, nonatomic) WCSession *session;
@end
@implementation InterfaceController
-(instancetype)init {
self = [super init];
if (self) {
if ([WCSession isSupported]) {
self.session = [WCSession defaultSession];
self.session.delegate = self;
[self.session activateSession];
}
}
return self;
}
- (IBAction)catPressed {
[self sendText:@"cat"];
}
- (IBAction)dogPressed {
[self sendText:@"dog"];
}
- (IBAction)pandaPressed {
[self sendText:@"panda"];
}
- (IBAction)bunnyPressed {
[self sendText:@"bunny"];
}
-(void)sendText:(NSString *)text {
NSDictionary *applicationDict = @{@"emoji":text};
[self.session updateApplicationContext:applicationDict error:nil];
}
ViewController.m
#import "ViewController.h"
#import <WatchConnectivity/WatchConnectivity.h>
@interface ViewController() <WCSessionDelegate>
@property (weak, nonatomic) IBOutlet UILabel *textLabel;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
if ([WCSession isSupported]) {
WCSession *session = [WCSession defaultSession];
session.delegate = self;
[session activateSession];
NSLog(@"HIIII");
}
}
- (void)session:(nonnull WCSession *)session didReceiveApplicationContext:(nonnull NSDictionary<NSString *,id> *)applicationContext {
NSString *text = [applicationContext objectForKey:@"text"];
dispatch_async(dispatch_get_main_queue(), ^{
[self.textLabel setText:[NSString stringWithFormat:@"Text: %@", text]];
});
}
我也經歷過這種情況,我需要首先在iPhone上打開父應用程序以開始在iPhone和Watch之間共享信息 –
