ios - 如何通过 Apple Watch 拨打电话？

Question

WatchKit有没有办法从分机​​拨打电话？

下面是我的代码。

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);
}];
