请帮助我获取该特定图像的资产URL。谢谢我认为您需要制作数据的本地副本,然后在数据库中保存对该本地副本的引用:
//create a fileName perhaps based on the contact name or a GUID
NSError *err;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);//find the cache dir. You might want to consider using the doc dir instead
NSString * path = [paths objectAtIndex:0];
path = [path stringByAppendingPathComponent:fileName];
[imgData writeToFile:path options:NSDataWritingAtomic error:&err];
if(!err)

///save path to the DB

SWIFT 3及以上版本的简单解决方案
var users = [User]()
func getContact(){
if #available(iOS 9.0, *) {
let contactStore = CNContactStore()
_ = [
CNContactFormatter.descriptorForRequiredKeys(for: .fullName),
CNContactEmailAddressesKey]
// Get all the containers
var allContainers: [CNContainer] = []
do {
allContainers = try contactStore.containers(matching: nil)
} catch {
print("Error fetching containers")
}
do {
try contactStore.enumerateContacts(with: CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey as CNKeyDescriptor, CNContactFamilyNameKey as CNKeyDescriptor, CNContactEmailAddressesKey as CNKeyDescriptor, CNContactImageDataKey as CNKeyDescriptor])) {
(contact, cursor) -> Void in
if (!contact.emailAddresses.isEmpty){
//self.email.append(String(contact.emailAddresses))
for emailAdd:CNLabeledValue in contact.emailAddresses {
let a = emailAdd.value
if a as String != ""{
for (index, data) in self.users.enumerated(){
if a as? String == data.email{
print("Emial found in Contact",index,a as String)
if contact.isKeyAvailable(CNContactImageDataKey) {
if let img = contact.imageData{
self.users[index] = User( id: self.users[index].id, firstName: self.users[index].firstName, lastName: self.users[index].lastName, email: self.users[index].email, user_type: self.users[index].user_type,user_image: UIImage(data: img))
print("imag",img)
}
}
}
}
self.email.append(a as String)
}
}
}
}
}
catch{
print("Handle the error please")
}
}else{
// Fallback
}
filteredData = email
dropDown.dataSource = filteredData
}
我不认为你可以得到资产的网址,你可以读图像和写它。为什么需要URL?@EsbenB,因为我需要将其保存到DB,我认为将图像作为数据保存到DB不是一个好主意。如果你有其他建议,对我会更有帮助。谢谢
