MsFinder helps you find memory s in your iOS apps at develop time. It can automatically find s in UIView and UIViewController objects, present an alert with the object in its View-ViewController stack when s happening. More over, it can try to find a retain cycle for the object using FBRetainCycleDetector. Besides finding s in UIView and UIViewController objects, developers can extend it to find s in other kinds of objects.

pod 'MsFinder'
MsFinder comes into effect after pod install, there is no need to add any code nor to import any header file.
WARNING: FBRetainCycleDetector is removed from the podspec due to Facebook's BSD-plus-Patents license. If you want to use FBRetainCycleDetector to find retain cycle, add pod 'FBRetainCycleDetector' to your project's Podfile and turn the macro MEMORY_S_FINDER_RETAIN_CYCLE_ENABLED on in MsFinder.h.
MsFinder can automatically find s in UIView and UIViewController objects. When s happening, it will present an alert with the object in its View-ViewController stack.
Memory
(
MyTableViewController,
UITableView,
UITableViewWrapperView,
MyTableViewCell
)
For the above example, we are sure that objects of MyTableViewController, UITableView, UITableViewWrapperView are deallocated successfully, but not the objects of MyTableViewCell.
If your class is designed as singleton or for some reason objects of your class should not be dealloced, override - (BOOL)willDealloc in your class by returning NO.
- (BOOL)willDealloc {
return NO;
}MsFinder finds s in UIView and UIViewController objects by default. However, you can extend it to find s in the whole object graph rooted at a UIViewController object.
- (BOOL)willDealloc {
if (![super willDealloc]) {
return NO;
}
MLCheck(self.viewModel);
return YES;
