If this selector exists and the property does not have a setter then an error is raised. If a property has a getter Foo then we check if a selector exists with the default selector name, i.e. In this case we can stretch the limits to try to find some missing property setters. If something is missing then we have no way to test it.

Missing setters: In general, we can only test what’s present.

If instancesRespondToSelector: returns false then an error is raised.

Instance selectors: A similar test case does the same for every instance method and tries all selectors.

If respondsToSelector: returns false then an error is raised.

Static selectors: One test case checks every type, inheriting from NSObject, inside your assembly and tries every on static methods.

If you only bind new APIs, you might be shipping old, missing, APIs without realizing it. missing source files, wrong defines…) even if they are documented and present in the header files.įinally, some library updates might introduce breaking changes, including removed API entry points. Your bindings might include selectors that are not part of the native library binary (e.g. easy to forget, unusable without it!ĬCRotateBy Create (float duration, float deltaAngle) Ī less common issue is wrong builds. +(id) actionWithDuration:(ccTime)duration angle:(float)angle The Objective-C static method declaration:

However, it is also a common error to forget the attribute when a selector starts with a plus sign ( +) character. without the ':' this method won't work For example, the following Objective-C method declaration: In fact, the all time favorite issue is likely the infamous missing colon at the selector’s end (when parameters are used). As such, it shares a lot of similarities with the attribute-including the main cause of issues: typos.
