Question

我正在寻求帮助，尝试使用MRProgress框架更新进度指示器。我能够设置进度指示器，但我不知道如何计算和更新其进度。我正在使用CloudKit并尝试在保存CKRecord时显示进度。有人可以给我一些方向吗？提前谢谢！

self.hud = [MRProgressOverlayView showOverlayAddedTo:self.myCollectionView animated:YES];
self.hud.mode = MRProgressOverlayViewModeDeterminateCircular;
self.hud.titleLabelText = @"Uploading...";

// prepare the CKRecord and save it
[self.ckManager saveRecord:[self.ckManager createCKRecordForImage:self.imageDataAddedFromCamera] withCompletionHandler:^(CKRecord *record, NSError *error) {
      if (!error && record) {
             NSLog(@"INFO: Record saved successfully for recordID: %@", record.recordID.recordName);
             // need to get the recordID of the just saved record before adding the CID to the CIDArray
             self.imageDataAddedFromCamera.recordID = record.recordID.recordName;
             [self.imageLoadManager addCIDForNewUserImage:self.imageDataAddedFromCamera]; // update the model with the new image
             // update number of items since array set has increased from new photo taken
             self.numberOfItemsInSection = [self.imageLoadManager.imageDataArray count];
             //[MRProgressOverlayView dismissAllOverlaysForView:self.view animated:YES];
             [self.hud dismiss:YES];
             [self.hud removeFromSuperview];
      } else {
             NSLog(@"ERROR: Error saving record to cloud...%@", error.localizedDescription);
             [self alertWithTitle:@"Yikes!" andMessage:@"We encountered an issue trying to upload your photo to the cloud."];
            }
}];

更新：在我的CKManager类中将easykit API中的cloudkit方法转换为CKOperations。我可以通过日志记录看到进度更新，但我不知道如何将其恢复到viewcontroller。如果我要将它添加到完成处理程序中，那么只有在一切完成后才将其发回？这是我更新的代码......

CKManager.h - （void）saveRecord：（NSArray *）记录withCompletionHandler：（void（^）（NSArray * records））completionHandler;

CKManager.m - （void）saveRecord：（NSArray *）记录withCompletionHandler：（void（^）（NSArray *））completionHandler {

NSLog(@"INFO: Entered saveRecord...");
CKModifyRecordsOperation *saveOperation = [[CKModifyRecordsOperation alloc] initWithRecordsToSave:records recordIDsToDelete:nil];

saveOperation.perRecordProgressBlock = ^(CKRecord *record, double progress) {
    if (progress <= 1) {
        NSLog(@"Save progress is: %f", progress);
    }
};

saveOperation.completionBlock = ^ {
    NSLog(@"Save operation completed!");
    completionHandler(records);
};

[self.publicDatabase addOperation:saveOperation];

}

如果要显示操作的进度，则必须使用CKModifyRecordsOperation并使用perRecordProgressBlock方法。

使用MRProgress更新进度
