requestAccessToEntity iOS6-向后兼容性 - EKEventStore [英] requestAccessToEntity iOS6- Backwards compatibility - EKEventStore

问题描述

关注iOS6 eventKit和新的隐私设置我正在使用以下代码 - 这在iOS6设备上完全正常。

following iOS6 eventKit and the new privacy settings I am using the following code - which works perfectly fine on iOS6 devices.

仍然，我想要相同的代码也适用于iOS 5.x的设备，我希望不要两次写相同的代码 - 似乎错了。

Still, I would like the same code to work also for devices with iOS 5.x and I wish not to write a the "same code" twice - Seems wrong.

任何人都可以协助优雅解决方案？

 EKEventStore *eventStore = [[EKEventStore alloc] init];
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {

// some code 


}];

推荐答案

我正在使用：

void (^addEventBlock)();

addEventBlock = ^
{
    NSLog(@"Hi!");
};

EKEventStore *eventStore = [[UpdateManager sharedUpdateManager] eventStore];

if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
{
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
     {
         if (granted)
         {   
             addEventBlock();
         }
         else
         {
             NSLog(@"Not granted");
         }
     }];
}
else
{
    addEventBlock();
}

我认为应该减少代码重复。

I think that should reduce code duplication.
