我正在使用Parse作为后端在iOS上构建应用程序。
这样做我使用Parse Facebook SDK,首先将Facebook链接到我的Parse用户,然后查询他的数据并保存。
问题是:有时候我没有得到一些信息,比如eMail(userData [@“email”]是nil),first_name,name ..或者Profile Pic没有'下载。
并非所有时间(实际上非常罕见),并且无法可靠地复制问题,因此我可以解决它。而且通常只有一个缺失的领域不是全部。
所以我在我的数据库中遇到漏洞(当用户的电子邮件地址不是很酷: 我的主要关注 )
以下是我编写方法的方法(我编辑了大部分if(错误)管理以使其更短)。
有什么想法吗?
谢谢你们!
NSArray *permissionsArray = @[@"public_profile",@"email", @"user_friends"];
[PFFacebookUtils initializeFacebook];
// Login PFUser using Facebook
[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
if (user.isNew) {
NSLog(@"User with facebook signed up and logged in!");
[self fbData:self];
} else {
NSLog(@"User with facebook logged in!");
[self fbDataAlreadyLog:self];
}
}];
然后我调用我的“fbData”函数,以便将用户数据填入Parse:
-(IBAction)fbData:(id)sender{
[PFFacebookUtils initializeFacebook];
FBRequest *request = [FBRequest requestForMe];
// Send request to Facebook
[request startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *userCloud, NSError *error) {
if (!error) {
// result is a dictionary with the user's Facebook data
NSDictionary *userData = userCloud;
NSString *facebookID = userData[@"id"];
NSURL *pictureURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1", facebookID]];
PFUser *user = [PFUser currentUser];
if (userData[@"name"]) {
user[@"name"] = userData[@"name"];
}
if (userData[@"first_name"]) {
user[@"first_name"] = userData[@"first_name"];
}
if (userData[@"last_name"]) {
user[@"last_name"] = userData[@"last_name"];
}
if (userData[@"id"]) {
user[@"fbID"] = userData[@"id"];
}
if (userData[@"gender"]) {
user[@"gender"] = userData[@"gender"];
}
if (userData[@"email"]) {
user.email = userData[@"email"];
user.username = userData[@"email"];
}
if (userData[@"age_range"]) {
user[@"age_range"] = userData[@"age_range"];
}
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:pictureURL
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize)
{
// progression tracking code
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished,NSURL *imageURL)
{
if (image)
{
// do something with image
NSData *imageNSData = UIImagePNGRepresentation(image);
PFFile *imageFile = [PFFile fileWithName:@"profilePic" data:imageNSData];
user[@"image"] = imageFile;
[user saveInBackgroundWithBlock];
//Once the Save Block is done I managed a few more thing before moving on to the next ViewController
}
}];
}];
答案 0 :(得分:1)
试试这个
NSArray *permissionsArray = @[ @"user_about_me", @"user_relationships", @"user_birthday", @"user_location"];
