I am using the CoreSpotLight api to index some content. For some reason I am not able to find the data when I search in the
SpotLight.
let atset:CSSearchableItemAttributeSet = CSSearchableItemAttributeSet()
atset.title = "Simple title"
atset.contentDescription = "Simple twitter search"
let item = CSSearchableItem(uniqueIdentifier: "id1", domainIdentifier: "com.shrikar.twitter.search", attributeSet: atset)
CSSearchableIndex.defaultSearchableIndex().indexSearchableItems([item]) { (error) -> Void in
print("Indexed")
}
When I run the app I see that the data is indexed and the error is nil.
Also I have added the CoreSpotLight and MobileCoreServices to the build phase.
Try use itemContentType initializer like so :
let atset:CSSearchableItemAttributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeImage as String)
atset.title = "Simple title"
atset.contentDescription = "Simple twitter search"
let item = CSSearchableItem(uniqueIdentifier: "id1", domainIdentifier: "com.shrikar.twitter.search", attributeSet: atset)
CSSearchableIndex.defaultSearchableIndex().indexSearchableItems([item]) { (error) -> Void in
print("Indexed")
}
The kUTTypeImage is declared in MobileCoreServices.

Set the maxSize to a ridiculously high number 1*2000000*2000000.
Thank you!
Is it possible that you are storing the full https URL in the database and are trying to create a reference by adding the full https url as a child to the storage reference?
I think you should try to either store just the path and name in your database or you change your download code to use the https URL.
// Create a reference from an HTTPS URL
// Note that in the URL, characters are URL escaped!
let httpsReference = storage.reference(forURL: "https://firebasestorage.googleapis.com/b/bucket/o/images%20stars.jpg")
httpsReference.getData(maxSize: ...
Also you're running your getData method inside DispatchQueue.main.async. getData has itself a completion handler and might take some time, when you run that inside of DispatchQueue.main.async it will block your code until the download is done. Only put code that update the UI inside DispatchQueue.main.async. In your case as soon as you do something with your workoutPicsArray or the UIImage to update your view.
Have a look here to see if you can figure out how you are actually trying to get the data. It might be helpful to put a print() after each line to see what you are creating and using at what point.
Download Files on iOS
Thanks in advance for any help. I am trying to get Batch items (Load multiple) items from one DynamoDb table using the AWS iOS SDK (Swift). I can load one item using the Block syntax, but I need to load 10 or more than that. I don't want to use 10 Block calls to load them individually. I tried to follow the attach stackoverflow Link (where the similar solution is given) but I am getting the following compiler error message. I come from Java background, hence could also be a syntax issue. Is it the right way to load multiple items? I don't want to use low level API. Any help, where I am going wrong. Thanks.
aws dynamodb how to use object mapper with batch get in ios
let dynamoDBObjectMapper = AWSDynamoDBObjectMapper.default()
var tasksList = Array<AWSTask<AnyObject>>()
for i in 1...10 {
tasksList.append(dynamoDBObjectMapper.load(AWSCards.self, hashKey: "SH_"+String(i), rangeKey: nil))
}
AWSTask.init(forCompletionOfAllTasksWithResults: tasksList).continueWithBlock { (task) -> AnyObject? in
if let cards = task.result as? [AWSCards] {
print(cards.count)
}
else if let error = task.error {
print(error.localizedDescription)
}
return nil
}
Have a try with the following codes (Swift 4.1, Feb 9th, 2018):
let dynamoDBObjectMapper = AWSDynamoDBObjectMapper.default()
var tasksList = Array<AWSTask<AnyObject>>()
for i in 1...10 {
tasksList.append(dynamoDBObjectMapper.load(AWSCards.self, hashKey: "SH_"+String(i), rangeKey: nil))
}
AWSTask<AnyObject>.init(forCompletionOfAllTasksWithResults: tasksList).continueWith { (task) -> Any? in
if let cards = task.result as? [AWSCards] {
print(cards.count)
}
else if let error = task.error {
print(error.localizedDescription)
}
return nil
}
Your question is "how to use the object mapper" but it might be more efficient for you to not use it.
However, there is a way to use it. See Niklas's answer here and here (he copy & pasted), but something about it strikes me as fishy. I want to make the assertion that it is not as fast as the built-in batch-get function, but I am unsure. I suspect that this does not complete the items in parallel, or at least not as efficiently as in BatchGetItem.
See the docs: "In order to minimize response latency, BatchGetItem retrieves items in parallel."
According to Yosuke, "Currently, AWSDynamoDBObjectMapper does not support the batch get item. You need to load one item at a time if you want to use the object mapper" as of 2016. This still seems to be the case. I am using a version a couple versions behind, but not too far behind. Someone check.
In conclusion, if you are loading one item at a time, you are likely missing out on the whole purpose of BatchGetItem (low latency).
Pulling from various sources, including John Davis's question here, I have tested and ran this BatchGetItem result. Here ya go.
import AWSDynamoDB
let primaryKeyToSortKeyDict : [String : String] = .... // Your stuff
var keys = [Any]()
for key in primaryKeyToSortKeyDict.keys {
let partitionKeyValue = AWSDynamoDBAttributeValue()
partitionKeyValue?.s = String(key)
let sortValue = AWSDynamoDBAttributeValue()
sortValue?.s = String(primaryKeyToSortKeyDict[key]!)
keys.append(["partitionKeyAttributeName": partitionKeyValue, "sortKeyAttributeName": sortValue])
}
let keysAndAttributesMap = AWSDynamoDBKeysAndAttributes()
keysAndAttributesMap?.keys = keys as? [[String : AWSDynamoDBAttributeValue]]
keysAndAttributesMap?.consistentRead = true
let tableMap = [table : keysAndAttributesMap]
let request = AWSDynamoDBBatchGetItemInput()
request?.requestItems = tableMap as? [String : AWSDynamoDBKeysAndAttributes]
request?.returnConsumedCapacity = AWSDynamoDBReturnConsumedCapacity.total
guard request != nil else {
print("Handle some error")
return
}
AWSDynamoDB.default().batchGetItem(request!) { (output, error) in
print("Here is the batchgetitem output")
if error == nil {
// do output stuff
} else {
// handle error
}
}
I'm adding my interested Place to Google Place with my APP. Place is getting added successfully, but the address field is empty.
Here is Code:
{
GMSPlacesClient.provideAPIKey(googlePlaceAPIKEY)
let placesClient = GMSPlacesClient.shared()
let userAddedPlace = GMSUserAddedPlace()
userAddedPlace.name = "NightClub & Bar"
userAddedPlace.address = "48 Gandhi Road, Bandra, Mumbai, Maharastra"
userAddedPlace.coordinate = CLLocationCoordinate2DMake(19.017615 , 72.856164)
userAddedPlace.phoneNumber = "9999999999"
userAddedPlace.website = "http://www.google.com/"
userAddedPlace.types = ["bar"]
placesClient.add(userAddedPlace, callback: { (place, error) -> Void in
if let error = error {
print("Add Place error: \(error)")
return
}
if let place = place {
print("Added place with placeID \(place.placeID)")
}
})
}
I can see "NightClub & Bar" in my place list but the address "48 Gandhi Road, Bandra, Mumbai, Maharastra" is not there.
Can anyone tell me what mistake I made?
It seems that there is a dictionary value I can place in the GET call that corresponds to a property on PDKPin that I can call in my success block to unpack the value, i.e. "url" = PDKPin.url "note" = PDKPin.decriptionText, however I can't find a corresponding property for "link" which is available per the documentation https://developers.pinterest.com/docs/api/pins/?
PDKClient.sharedInstance().getAuthenticatedUserPinsWithFields(Set(["url", "note", "link"]), success:
{ (responseObject :PDKResponseObject!) -> Void in
print("success /(pdk)")
let currentResponseObject = responseObject
let pins = currentResponseObject.pins
self.pinArray = pins()
for pin in self.pinArray {
if let pinAsPDKPin = pin as? PDKPin {
print(pinAsPDKPin.descriptionText)
if let safeURL = pinAsPDKPin.url {
print(safeURL)
}
let link = pinAsPDKPin.link //no such property on PDKPin
}
}
}) { (err :NSError!) -> Void in
print("error NSError: \(err)")
}
It looks kinda weird, but as per the implementation, the 'link' property(from the API) is used as 'url'(in the SDK). Check out the code here : https://github.com/pinterest/ios-pdk/blob/master/Pod/Classes/PDKPin.m#L38
So, if all that you care about is the 'link' from the API, then just access 'url' in the SDK(in PDKPin object).
I am new to swift . I used APAdressBook Framework for retrieving contacts in iPhone .Every thing working fine up to IOS 8.4 but when checked in IOS 9 of Simulator and iPhone devices it is not accessing contacts and even it not showing alert message like would you like to access contacts any one can face this type of problem if yes please give me your valuable answer?
Apple Inc. introduce Contacts.framework from iOS 9. So, it would be better use this framework to retrieve contacts.
Here is way to fetch email or whole contact from Contacts app.
Add Contacts.framework to your project.
Create or add new file of type header and give name like yourProjectName-Bridging-Header.h write #import <Contacts/Contacts.h> statement into file and save and set appropriate path of this file from build setting.
Now create method
func getAllContacts() {
let status = CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts) as CNAuthorizationStatus
if status == CNAuthorizationStatus.Denied {
let alert = UIAlertController(title:nil, message:"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can use contacts", preferredStyle:UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title:"OK", style:UIAlertActionStyle.Default, handler:nil))
self.presentViewController(alert, animated:true, completion:nil)
return
}
let store = CNContactStore()
store.requestAccessForEntityType(CNEntityType.Contacts) { (granted:Bool, error:NSError?) -> Void in
if !granted {
dispatch_async(dispatch_get_main_queue(), { () -> Void in
// user didn't grant access;
// so, again, tell user here why app needs permissions in order to do it's job;
// this is dispatched to the main queue because this request could be running on background thread
})
return
}
let arrContacts = NSMutableArray() // Declare this array globally, so you can access it in whole class.
let request = CNContactFetchRequest(keysToFetch:[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, CNContactFormatter.descriptorForRequiredKeysForStyle(CNContactFormatterStyle.FullName)])
do {
try store.enumerateContactsWithFetchRequest(request, usingBlock: { (contact:CNContact, stop:UnsafeMutablePointer<ObjCBool>) -> Void in
let arrEmail = contact.emailAddresses as NSArray
if arrEmail.count > 0 {
let dict = NSMutableDictionary()
dict.setValue((contact.givenName+" "+contact.familyName), forKey: "name")
let emails = NSMutableArray()
for index in 0...arrEmail.count {
let email:CNLabeledValue = arrEmail.objectAtIndex(index) as! CNLabeledValue
emails .addObject(email.value as! String)
}
dict.setValue(emails, forKey: "email")
arrContacts.addObject(dict) // Either retrieve only those contact who have email and store only name and email
}
arrContacts.addObject(contact) // either store all contact with all detail and simplifies later on
})
} catch {
return;
}
}
}
Call this method where you want self.getAllContacts()
And when you want to retrieve
for var index = 0; index < self.arrContacts.count; ++index {
let dict = self.arrContacts[index] as! NSDictionary
print(dict.valueForKey("name"))
print(dict.valueForKey("email"))
}
