如何拨打Apple Watch的电话？

有没有办法从WatchKit扩展拨打电话？

以下是我的代码。

 NSExtensionContext *ctx = [[NSExtensionContext alloc] init]; NSString *cleanedString = [[@"1234567890" componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""]; NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", cleanedString]]; [ctx openURL:telURL completionHandler:^(BOOL success) { NSLog(@"fun=%s after completion. success=%d", __func__, success); }];
