我需要从AddressBook框架转换此函数的返回值:
ABRecordCopyValue(nil, kABPersonPhoneProperty)
到ABMultiValueRef类型的值
此功能目前标记为:
func ABRecordCopyValue(record: ABRecordRef!, property: ABPropertyID) -> Unmanaged<AnyObject>!
所以我可以将它转换为Unmanaged,如下所示:
ABRecordCopyValue(person, kABPersonPhoneProperty) as Unmanaged<ABMultiValueRef>
但是,我怎样才能将它作为ABMultiValueRef,以便我可以将它传递给这个函数？
func ABMultiValueGetIndexForIdentifier(multiValue: ABMultiValueRef!, identifier: ABMultiValueIdentifier) -> CFIndex
我这样做了:
let managedPhones = Unmanaged.fromOpaque(phones.toOpaque()).takeUnretainedValue() as ABMultiValueRef
我一直收到这个编译错误:
Bitcast requires both operands to be pointer or neither
%89 = bitcast %objc_object* %88 to %PSs9AnyObject_, !dbg !325
LLVM ERROR: Broken function found, compilation aborted!
