It is important to carefully observe the parameter naming conventions. Visual Design tools that provide context-related help and class browsing functions will display the parameter names of methods to users in the designer. The following rules
Fortunately, I have seen this before.
The division of the moving phase is used.
K = x/y B = x % Y then x = Ky + B
If an integer can divide X and Y at the same time, it must be able to divide B and Y at the same time, and the number that can
◆ Hungarian naming law
The basic principle is:
Variable name = property + Type + Object Description
(1) attributes:
Global variable: G _
Constant: C _
Class member variable: M _
(2) Type:
Array:
Boolean: B byte:
CHAR: C Byte
I only speak for c ++ programmers. Other languages are not familiar with, but they should be similar. Once upon a time, I opened my 21-day Beginner Books on c ++ series, all of which were presented by the Hungarian naming method (DWORD dwXXX, int
In this case, the attribute name contains keywords.
You can solve this:
Renaming that property:@property (strong, nonatomic) NSString *theNewTitle;
Keeping the property name and specifying a getter name that doesn't begin with one of the special

normally.The answer is no. If you use __stdcall, the above problem is solved, the function solves the cleanup work by itself. So we all use __stdcall (although sometimes WINAPI) in the call to the Cross (development) platform. So why do we need _cdecl? When we encounter such a function such as fprintf () its parameters are variable, indefinite length, the caller can not know the length of the parameters in advance, the removal of the subsequent work can not be normal, therefore, this situation
