ios - How to keep an __autoreleasing address as a strong property in a class? -


How do I create a strong asset for a variable in a NSObject ? I have a class named SCPFMessageThreadQuery which is allocated by passing the address of a SCPFMessageThread variable. 

  @interface SCPFMessageThreadQuery () / / This declaration seems right. @property (nanatomic) scripfiles and rhythm * __ strong * thread; - (id) initWithRootMessage: (SCPFMessage *) Root thread address: (SCPFMessageThread **) address; @end @implementation SCPFMessageThreadQuery // In any way, during the autocomplete, in any way, type of ownership __autoreleasing. - (id) initWithRootMessage: (SCPFMessage *) Root thread address: (SCPF message press * __ autorelizing *) Address {if (self = [super init]) {_root = root; // Here the error complains about changing the ownership of the Xcode address _thread = address; } Healthy return; } @end

The error I am getting is:

'SCPFMMGetTrade * __ Autoreliving *' from 'SCPFMMSGetStread * __Secondant * Pointer Release Properties

I am planning to use this class with my Visual Controller as follows: 

  SCPFMessageThread * thread = self.thread; // self Can not thread the SCPF message press * query = [[SCPFMASETTREADread alloc] initWithRootMessage: self.rootMessage threadAddress: & thread];

I really have to pass here to know. To complete the information for an object ( SCPFMessageThread ) in the code of the app, I will make several calls to our API. Please do not ask me why the API does not JOIN instead of itself.

Problem showing this: 

  @ interface (appended) @ Property NSSTING * __strop * ivar; @end @implementation AppDelegate - (zero) Store Interactive: (NSString * __autoreleasing *) equals {id xpar = * par; _ivar = & amp; Xper; } @end

With dereference you are an indicator for a pertinent object only (and not "pointer to pointer in a reactant object") ARC subject is. Therefore, the object xpar is retained - and is issued at the end of the method.

Of course you can put xpar in a property. But it makes it clear that the whole code is useless: in the ARC, duplicate misconduct will be lost. ARC cares about the objects behind an indicator, if it is a constant object, your pointer points to the pointer, which is not a retinal object.

I do not think this is a simple solution. (Although you can use CFRetain () et al. If you do not care for more or less theoretical CFRetain () CF object problem.) < / P>

Even you have explicitly confirmed this: Why do you need an extra layer of indirect? If you really need it, in fact, think about an additional object in between: 

  @interface NSStringRetainableReference @property NSString * string; @end @implementation @end

Pass an example object of this class in the form of argument. Then you have an indicator for a reputable object and there is an objection at the other level. But in this case it is made from an object.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
