`-Wno-protocol'
|
|
If a class is declared to implement a protocol, a warning is
|
|
issued for every method in the protocol that is not implemented by
|
|
the class. The default behavior is to issue a warning for every
|
|
method not explicitly implemented in the class, even if a method
|
|
implementation is inherited from the superclass. If you use the
|
|
`-Wno-protocol' option, then methods inherited from the superclass
|
|
are considered to be implemented, and no warning is issued for
|
|
them.
|
|
`-Wselector'
|
|
Warn if multiple methods of different types for the same selector
|
|
are found during compilation. The check is performed on the list
|
|
of methods in the final stage of compilation. Additionally, a
|
|
check is performed for each selector appearing in a
|
|
`@selector(...)' expression, and a corresponding method for that
|
|
selector has been found during compilation. Because these checks
|
|
scan the method table only at the end of compilation, these
|
|
warnings are not produced if the final stage of compilation is not
|
|
reached, for example because an error is found during compilation,
|
|
or because the `-fsyntax-only' option is being used.
|
|
`-Wstrict-selector-match'
|
|
Warn if multiple methods with differing argument and/or return
|
|
types are found for a given selector when attempting to send a
|
|
message using this selector to a receiver of type `id' or `Class'.
|
|
When this flag is off (which is the default behavior), the
|
|
compiler will omit such warnings if any differences found are
|
|
confined to types which share the same size and alignment.
|
|
`-Wundeclared-selector'
|
|
Warn if a `@selector(...)' expression referring to an undeclared
|
|
selector is found. A selector is considered undeclared if no
|
|
method with that name has been declared before the
|
|
`@selector(...)' expression, either explicitly in an `@interface'
|
|
or `@protocol' declaration, or implicitly in an `@implementation'
|
|
section. This option always performs its checks as soon as a
|
|
`@selector(...)' expression is found, while `-Wselector' only
|
|
performs its checks in the final stage of compilation. This also
|
|
enforces the coding style convention that methods and selectors
|
|
must be declared before being used.
