在联系人应用程序中,有像“iCloud”,“yahoo”,“gmail”这样的群组。在swift中,是否可以仅从gmail源获取联系人?

经过测试的代码。希望它能解决你的问题...
func getAppropriateName(for container: CNContainer?) -> String? {
var name = ""
if (container?.name == "Card") || container?.name == nil {
name = "iCloud"
}
else if (container?.name == "Address Book") {
name = "Google"
}
else if (container?.name == "Contacts") {
name = "Yahoo"
}
else {
name = "Facebook"
}
return name
}

iCloud / yahoo / gmail等是CNContainer。 Gmail / iCloud的类型为CNContainerTypeCardDAV。首先,您需要获取所有联系人,然后根据该联系人的CNContainerType过滤数组。但不幸的是,我们无法确定它是哪种CardDav,即iCloud / Gmail。

您可以通过查看此处的Contacts框架运行时标头来实现此目的:https://github.com/JaviSoto/iOS10-Runtime-Headers/tree/master/Frameworks/Contacts.framework
您可以通过performSelector
消息给他们打电话。它有点乱,但有效。
一般来说,您需要做的是:
CNContactStore* store = [CNContactStore new];
// fetch accounts that sync contacts with your device (array of CNAccount)
// since CNAccount class isn't available by default, we treat it as NSObject for our puproses
NSArray* accounts = [store performSelector:@selector(accountsMatchingPredicate:error:) withObject:nil withObject:nil];
// you can iterate through this array, I just use first one for this example
NSObject* account = [accounts firstObject];
// get identifier of the account for NSPredicate we use next
NSString* accountId = [account performSelector:@selector(identifier)];
// Display name of the account (aka Yahoo, Gmail etc.)
NSString* accountName = [account performSelector:@selector(_cnui_displayName)];
// NSPredicate that help us to get corresponding CNContainer
NSPredicate* containerPredicate = [[CNContainer class] performSelector:@selector(predicateForContainersInAccountWithIdentifier:) withObject:accountId];
// Fetching CNContainer
CNContainer* container = [[store containersMatchingPredicate:containerPredicate error:nil] firstObject];
之后,所有关于CNContainers的一般用法。 希望它会有所帮助。
PS。它适用于iOS 10,对于将来应该检查Contacts.framework运行时更改的版本。
PPS。我没有检查swift,但也应该工作。
抱歉我的英文。 祝你好运:)
