CocoaPods.org 上的 MGEvents

MGEvents

MGEvents 提供了一个极其轻量级的 API，用于键路径观察、UIControl 事件处理以及观察和触发自定义事件。

pod 'MGEvents'

#import <MGEvents/MGEvents.h>

[box onChangeOf:@"selected" do:^{
    NSLog(@"the new selected value is: %d", box.selected);
}];

[button onControlEvent:UIControlEventTouchUpInside do:^{
    NSLog(@"i've been touched up inside. golly.");
}];

或者在 Swift 中

button.onControlEvent(.TouchUpInside) {
    print("you touched me!")
}

[earth on:@"ChangedShape" do:^{
    NSLog(@"the earth has changed shape");
}];

然后触发事件

[earth trigger:@"ChangedShape"];
