Illustrative methods
With reference to above-mentioned application scenarios, pair according to exemplary embodiment of the invention is described referring to figs. 1 to Fig. 6
The destructed method of elephant.
Fig. 1 diagrammatically illustrates the flow chart of the destructed method of object according to an embodiment of the invention.
Shown in reference picture 1, the destructed method of object according to an embodiment of the invention, including：
Step S10, at the end of the life cycle of destination object, it is destructed that line delay is entered to the destination object.
It should be noted that in embodiments of the present invention, the life cycle of object terminates where being object
Function is modulated with finishing.
In addition, in embodiments of the present invention, when it is determined that destination object is entered line delay it is destructed when, the mesh can be discharged
Mark the association attributes of object reference.
In embodiments of the present invention, due to many system classes in program being present, such as in ISO systems
NSString, UIView etc. are created, release is very frequent, and the probability that wild pointer occurs for these examples is very low, in order to improve effect
Rate, without all carrying out wild pointer protection to all objects.Therefore, embodiments of the present invention provide determination as shown in Figure 2
The scheme of the destination object of progress wild pointer protection is needed, is specifically included：
Whether step S20, each object in determining program need to carry out wild pointer protection.
In embodiments of the present invention, it can judge whether each object needs according to the type of each object in program
Carry out wild pointer protection.Such as some objects for system class, without carrying out wild pointer protection, and for self defined class
Some objects, then it can carry out wild pointer protection.
In an exemplary embodiment of the present invention embodiment, step S20 can include：Replaced and be used for by the new method of definition
The method for creating each object, judges whether each object needs progress wild pointer to prevent in the new method
Shield.
For example for IOS systems, method swizzling can be utilized to replace NSObject's (class in IOS systems)
AllocWithZone (method that class example is created in IOS systems) method, then judges whether object needs in new method
Carry out wild pointer protection.
Step S22, if it is determined that any object in program needs to carry out wild pointer protection, then any object is added
Mark, and the object of the mark will be with the addition of as the destination object.
In an exemplary embodiment of the present invention embodiment, adding the step of identifying to any object in step S22 can include：
Any object described in function pair based on dynamic addition affiliated partner adds the mark.
For example for IOS systems, (it can dynamically add and close in IOS systems by objc_setAssociatedObject
Joining the function of object) affiliated partner is that the needs carry out the object of wild pointer protection and set mark, extended meeting after identified object
Into follow-up protection flow.
With continued reference to Fig. 1, the destructed method of described object also includes：
Step S12, the destination object was entered in the line delay destructed period, the target pair will be sent to originally
The method of elephant is forwarded to a do-nothing function pointer.
In embodiments of the present invention, shown in reference picture 3, step S12 comprises the following steps：
Step S121, the class pointed by the function pointer of destination object is revised as to specify class, wherein, the function pointer
Originally the primitive class of the destination object is pointed to.
For example for IOS systems, the function pointer (i.e. isa pointers) that destination object can be pointed to its primitive class originally is repaiied
Customized class is changed to point to, the customized class is the good class for being used to handle the destructed object of delay of predefined.
Step S122, intercepted based on the specified class and be sent to the method for the destination object originally, and be forwarded to described
Do-nothing function pointer.
In an exemplary embodiment of the present invention embodiment, step S122 includes：By specifying the message in class to forward function to block
The method for being sent to the destination object originally is cut, and returns to an object class；To object class dynamic addition class method, and will
The pointer of the class method points to do-nothing function.
For example for IOS systems, it can be intercepted by customized class and be sent to the method for destination object originally, and returned
One object class (such as stubProxy), then to object class dynamic addition selector (i.e. class method), make selector's
Imp pointers point to a do-nothing function, and the do-nothing function returns to 0.
It should be noted that the object being over for life cycle, embodiments of the present invention are that it is prolonged
When it is destructed, but it is final still need to carry out these objects destructed, based on this, the present invention proposes following end delay analysis
The scheme of structure：
In certain embodiments of the present invention, whether determining program switches to running background, and/or judges that delay is destructed
The quantity of destination object whether reach predetermined quantity；When judging that described program switches to running background, and/or judging to prolong
When destructed destination object quantity when reaching the predetermined quantity, call the destructed original releasing memory of destination object that is delayed
Function pair described in destination object carry out it is destructed.
Based on foregoing scheme, embodiments of the present invention additionally provide following scheme：The class name of the primitive class is protected
Deposit into the destination object.Obtain the class name for the primitive class being stored in the destination object；According to the class name got, system
The wrong data that sequence of having the records of distance by the log occurs in the process of running.
In embodiments of the present invention, by the way that the class name of the primitive class of destination object is preserved into destination object, and
The wrong data occurred in the process of running come statistics program according to the class name for the primitive class being stored in destination object so that energy
Enough it is effectively retained program and the field data of BAD ACCESS types collapse occurs, and then technical staff can be facilitated to carry out investigation and repaiied
It is multiple.
Below by taking IOS systems as an example, the destructed method of the object of embodiment of the present invention is described in detail, main bag
Containing following 4 processes：
1st, shown in reference picture 4, comprise the following steps：
Step S401, original allocWithZone methods in NSObject are replaced using method swizzling.
Step S402, judges whether the type object needs to carry out wild pointer protection in new method, if so, then performing
Step S403；Otherwise, step S404 is performed.
Step S403, it is that the object instance sets flag to mark by objc_setAssociatedObject, is labeled
Object after extended meeting enter protection flow.
Step S404, original allocWithZone methods are called to be handled.
Flow shown in Fig. 4 is particular by the original allocWithZone methods of hook come to needing to carry out wild pointer
The object instance addition mark of protection, so that follow-up process is identified.
2nd, shown in reference picture 5, comprise the following steps：
Step S501, the object being over for life cycle, NSObject is replaced using method swizzling
In original dealloc methods.
Step S502, judges whether object instance has flag marks, if so, then performing step S504；Otherwise, step is performed
S503。
Step S503, original dealloc methods are called to discharge the object instance.I.e. for wild pointer protection need not be carried out
Object instance, then the object instance is directly discharged by original dealloc methods.
Step S504, objc_destructInstance methods are called to discharge the reality object instance for having flag to mark
The association attributes that example is quoted.
Step S505, the isa of the object instance is revised as HTZombieObject classes.HTZombieObject classes are things
One first defined is specifically used to the class of the destructed object of processing delay, can be by so being sent to the method for the class object and disappearing
Breath is all forwarded on a do-nothing function pointer.
Step S506, original class name is stored in the example by objc_setAssociatedObject, for rear
Continuous error statistics use.
Whether step S507, the destructed object that judges to be delayed reach the upper limit, if so, then performing step S508；Otherwise, directly
Perform step S509.
Step S508, ht_freeSomeMemory release cachings are called, in order to which the object instance is added in caching.
Step S509, the object instance is added in caching.
3rd, shown in reference picture 6, comprise the following steps：
Step S601, the forwardingTargetForSelector methods in HTZombieObject are rewritten, to pass through
Message forwarding mechanism forwardingTargetForSelector intercepts all message for being transmitted to HTZombieObject.
Step S602, create stake class stubProxy.
Step S603, is selector corresponding to the dynamic addition of stake class, and selector imp points to do-nothing function, the sky letter
Number returns to 0.The purpose that program is not collapsed is reached by a function for being returned as sky.
Step S604, the primitive class of the object instance preserved before is obtained by objc_getAssociatedObject
Name, mistake of statistics data.
Step S605, return stubProxy is by message transfers to this class object.And then work as
After forwardingTargetForSelector intercepts the message for passing to HTZombieObject, the message can be turned
Move on on this class object, because the class method selector of this class object imp points to do-nothing function, therefore can finally return
0, the object instance that life cycle is over is have accessed even if realizing, can also ensure that the purpose that program is not collapsed.
4th, when program falls back on backstage or the destructed object instance that is delayed reaches the upper limit, then call destructed object original
The destructed object instance of all delays of dealloc methods release.
It should be noted that：Fig. 4 to Fig. 6 has been carried out in detail by taking IOS systems as an example to the destructed method of the embodiment of the present invention
Illustrate, those skilled in the art may be equally applicable for the embodiment of the present invention it is to be appreciated that for other operating systems
