在块目标c内调用块

Question

我希望在完成A座时调用B座（isInsertSuccess返回YES）。有人可以帮我使用下面的代码吗？谢谢。

A座

[userServiceInstance insertDataOnSuccess:^
 {
    if (![userServiceInstance isInsertSuccess]) {
                 NSLog(@“Insert is successful”);
    }
 }];

B座

[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){
    NSLog(@“This is the status, %ld”, status);
}];

你可以这样做：

[userServiceInstance insertDataOnSuccess:^{
   if (![userServiceInstance isInsertSuccess]) {
       NSLog(@“Insert is successful”);
       [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){
           NSLog(@“This is the status, %ld”, status);
       }];
   }
}];
