KVO-MVVM

Usage

1. First #import <KVO-MVVM/KVOUIView.h> or any other available header
2. Subclass your custom view from KVOUIView
3. Use mvvm_observe:with: or mvvm_observeCollection:with: like this:

   - (instancetype)initWithFrame:(CGRect)frame {
       if (self = [super initWithFrame:frame]) {

           [self mvvm_observe:@keypath(self.viewModel.title)
                         with:^(typeof(self) self, NSString *title) {
               self.titleLabel.text = self.viewModel.title;
           }];
           
           [self mvvm_observeCollection:@keypath(self.viewModel.values)
                                   with:^(typeof(self) self,
                                          NSArray<NSNumber *> *value,
                                          NSKeyValueChange change,
                                          NSIndexSet *indexes) {
               // ...
           }];

       }
       return self;
   }

4. Do not unobserve any KVO-observings any more

Observing keypaths with weak properties in it is not supported.

To run the example project, clone the repo, and run pod install from the Example directory first.
