google-objc-global-variable-declaration¶
Finds global variable declarations in Objective-C files that do not follow the pattern of variable names in Google’s Objective-C Style Guide.
The corresponding style guide rule: https://google.github.io/styleguide/objcguide.html#variable-names
All the global variables should follow the pattern of g[A-Z].* (variables) or k[A-Z].* (constants). The check will suggest a variable name that follows the pattern if it can be inferred from the original name.
For code:
static NSString* myString = @"hello";
The fix will be:
static NSString* gMyString = @"hello";
Another example of constant:
static NSString* const myConstString = @"hello";
The fix will be:
static NSString* const kMyConstString = @"hello";
However for code that prefixed with non-alphabetical characters like:
static NSString* __anotherString = @"world";
The check will give a warning message but will not be able to suggest a fix. The user need to fix it on his own.
