- ShareExtension中使用app groups NSUserDefaults获取储存的登录状态报错。信息如下:
NSUserDefaults *userDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.xxx.sharextension"];
if (![userDefaults objectForKey:@"isLogin"])
{
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"温馨提示"
message:@"请登录"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"确定"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
UIResponder* responder = self;
while ((responder = [responder nextResponder]) != nil)
{
if([responder respondsToSelector:@selector(openURL:)] == YES)
{
[responder performSelector:@selector(openURL:) withObject:[NSURL URLWithString:@"sharefile://"]];
}
}
}];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"取消"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {}];
[alert addAction:cancelAction];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
}
[User Defaults] Couldn't read values in CFPrefsPlistSource<0x1c010e340> (Domain:
group.cn.com.mengniu.oa.sharextension, User: kCFPreferencesAnyUser, ByHost:
Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers,
detaching from cfprefsd
- 网上说在储存App Groups时要添加Team ID。之后取值时虽然不会再报错，但取出来的值为nil。
Change from
[[NSUserDefaults alloc] initWithSuiteName:@"group.com.xxx.xxx"];
to
[[NSUserDefaults alloc] initWithSuiteName:@"nnnnnnnnnn.group.com.xxx.xxx"];
nnnnnnnnn is your team number, the one which you using to sign your code.
Tested under Xcode 8 GM and iOS 10 GM, and worked!
解决办法:用写文件的方法代替，取值时也取文件中的值。
//获取分组的共享目录
NSURL *groupURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.cn.com.mengniu.oa.sharextension"];
NSURL *fileURL = [groupURL URLByAppendingPathComponent:@"login.txt"];
if (success) {
resolve(@YES);
[@"isLogin" writeToURL:fileURL atomically:YES encoding:NSUTF8StringEncoding error:nil];
} else {
reject(@"101", @"login QuanShi SDK failed", error);
[@"isNotLogin" writeToURL:fileURL atomically:YES encoding:NSUTF8StringEncoding error:Nil];
}
判断App是否登录，若未登录提示登录，已登录则加载发送框。
NSURL *groupURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.cn.com.mengniu.oa.sharextension"];
NSURL *fileURL = [groupURL URLByAppendingPathComponent:@"login.txt"];
NSString *isLoginStatus = [NSString stringWithContentsOfURL:fileURL encoding:NSUTF8StringEncoding error:nil];
//如果未登录提示登录
if (isLoginStatus && [isLoginStatus isEqualToString:@"isNotLogin"]) {
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"请先登录办随，再分享"
message:nil
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"确定"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
UIResponder* responder = self;
while ((responder = [responder nextResponder]) != nil)
{
if([responder respondsToSelector:@selector(openURL:)] == YES)
{
[responder performSelector:@selector(openURL:) withObject:[NSURL URLWithString:@"sharefile://"]];
}
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}
}];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"取消"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}];
[alert addAction:cancelAction];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
}
else//已登录加载发送框
{
[self.view addSubview:container];
}
- 在Share Extension中展示AlertView。
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"请先登录办随，再分享"
message:nil
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"确定"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
UIResponder* responder = self;
while ((responder = [responder nextResponder]) != nil)
{
if([responder respondsToSelector:@selector(openURL:)] == YES)
{
[responder performSelector:@selector(openURL:) withObject:[NSURL URLWithString:@"sharefile://"]];
}
}
}];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"取消"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {
}];
[alert addAction:cancelAction];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
以上无法弹起AlertView，需要增加返回宿主App方法。 [self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"请先登录办随，再分享"
message:nil
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"确定"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
UIResponder* responder = self;
while ((responder = [responder nextResponder]) != nil)
{
if([responder respondsToSelector:@selector(openURL:)] == YES)
{
[responder performSelector:@selector(openURL:) withObject:[NSURL URLWithString:@"sharefile://"]];
}
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}
}];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"取消"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}];
[alert addAction:cancelAction];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];
*从ShareExtension中打开App的方法。因为openUrl只在Today Extension中可以用而在ShareExtension中不起作用。
解决办法:
NSURL * container = [NSURL URLWithString:@"sharefile://"];
UIResponder* responder = self;
while ((responder = [responder nextResponder]) != nil)
{
if([responder respondsToSelector:@selector(openURL:)] == YES)
{
[responder performSelector:@selector(openURL:) withObject:container];
}
}
NSURL *destinationURL = [NSURL URLWithString:@"sharefile://"];
// Get "UIApplication" class name through ASCII Character codes.
NSString *className = [[NSString alloc] initWithData:[NSData dataWithBytes:(unsigned char []){0x55, 0x49, 0x41, 0x70, 0x70, 0x6C, 0x69, 0x63, 0x61, 0x74, 0x69, 0x6F, 0x6E} length:13] encoding:NSASCIIStringEncoding];
if (NSClassFromString(className)) {
id object = [NSClassFromString(className) performSelector:@selector(sharedApplication)];
[object performSelector:@selector(openURL:) withObject:destinationURL];
}
