Firebase中的PUT请求如何

Question

我有titleField和UITextView。如何在Firebase中实现PUT请求并将文本字段的数据发送给Firebase？

Answer 1

NSDate * now = [NSDate date]; NSDictionary *post = @{@"sender": target text filed (self.textfield.text), @"message": self.textView.text, @"time": [NSDateFormatter localizedStringFromDate:now dateStyle:NSDateFormatterNoStyle timeStyle:NSDateFormatterShortStyle], }; NSDictionary *childUpdates = @{@"your storage link goes here/message.json": post}; [_ref updateChildValues:childUpdates] 

Answer 2

这取决于你想放在哪里。 如果你有一个简单的结构，找到数据库单元的链接。 https://YOUR_DATABASE_REF.firebaseio.com/CHILD/CHILD_OF_CHILD/

FIRDatabaseReference *reference = YOUR_REF; 

     NSDictionary *values = [NSDictionary dictionaryWithObjectsAndKeys: 
    self.textField.text,SOME_NAME"KEY",                                             nil]; 

[reference updateChildValues:values withCompletionBlock:^(NSError *__nullable err, FIRDatabaseReference * ref){ 
                    if(err) { 
                     NSLog(@"Error save"); 
                     return; 
                    } 
                    NSLog(@"Saved seccessfully in FireBace db"); 
                   }];
