Is there a meaning ascribed to where you put the pointer indicator "*" in Objective-C?

around this issue const is a postfix operator that refers to the thing to its left, as opposed to the right. If the const comes first then it applies to the first thing after it. const NSString *foo (as well as NSString const *foo) means that it's a non-const pointer to a const NSString - the pointer value can be reassigned, but the data being pointed to is immutable. NSString * const foo means that it's a const pointer to a non-const NSString - the data being pointed to can change but the location the pointer refers to cannot.
Spacing between the * and other parts of the line are just a matter of style and clarity.

iOS UIViewController,why "self" become to "wild pointer" in viewDidUnload?

fixed the issue. Will look into that further First, [super viewDidUnload] should be used as the last statement. However, that won't fix your error, probably.
The reason for your problem is quite simple. Your controller is overreleased somewhere. Do you have zombie detection enabled? The code where the application crashes is usually irrelevant because the problem happened earlier.

What is the meaning of "**&ptr" and "2**ptr" of C pointer?

it should still fix some issue Here, * and & operators cancel effect of each other when used one after another. 
**&ptr is the same as *ptr and here, ptr hold the address of x variable. So, print the value of x here.

Hope that helps It is a pointer to compound literals.
C11-§6.5.2.5 Compound literals (p9):
void f(void)
{
int *p;
/*...*/
p = (int [2]){*p};
/*...*/
}

I wish did fix the issue. There's no sugar coating it: According to the document you reference, you cannot. Under the Supported Operators section it says [emphasis added]:
