我必须在我的项目中使用自定义的多图像选择第三方文件夹来选择图像，并且这些图像以数组形式出现。的链接，自定义图像选择这个CreolePhotoSelection.将图像阵列上传到IOS中的服务器
现在我想要上传图片到服务的阵列，但它给我这个错误：
-[__NSDictionaryM CGImage]: unrecognized selector sent to instance 0x60800024dce0 2017-07-31 12:41:46.777 PK.House[7795:1224040] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSDictionaryM CGImage]: unrecognized selector sent to instance 0x60800024dce0'
我的代码上传图片是，
-(void)submit

[dateFormat setDateFormat:@"yyyyMMddHHmmss"];
NSDate *now = [[NSDate alloc] init];
NSString *theDate = [dateFormat stringFromDate:now];

"theDate: |%@| ", theDate);

imagecount++;

NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo";
NSString *headerBoundary = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",stringBoundary];
[dataRqst addValue:headerBoundary forHTTPHeaderField:@"Content-Type"];
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:imageData];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"--%@--\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[dataRqst setHTTPBody:postBody];
NSHTTPURLResponse* response =[[NSHTTPURLResponse alloc] init];
NSLog(@"Response is %@",response);
NSError* error = nil ;
NSLog(@"Error is %@",error);
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:dataRqst delegate:self];
NSLog(@"Connection is %@",conn);
}
#pragma mark NSURLConnection Delegate Methods

}

}
我的选择图片的代码是这样的：
- (IBAction)Select:(id)sender
{
CreolePhotoSelection *objCreolePhotoSelection= [[CreolePhotoSelection alloc] initWithNibName:@"CreolePhotoSelection" bundle:nil];
objCreolePhotoSelection.strTitle = @"Images";
objCreolePhotoSelection.delegate = self; // It will help to retrive all selected photos from CreolePhotoSelection
objCreolePhotoSelection.arySelectedPhoto = _arrImages; // You need to pass same array which is holding selected image
objCreolePhotoSelection.maxCount = 50; // Eg. 5, 10 anythings...
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:objCreolePhotoSelection];
[self.navigationController presentViewController:navController animated:YES completion:nil];
}
及其功能是这些：
-(void)getSelectedPhoto:(NSMutableArray *)aryPhoto
{
// //Initlize array
// NSArray *aryAlImage = [aryPhoto valueForKeyPath:@"mainImage"];
//
// NSMutableArray *ary = [[NSMutableArray alloc] initWithArray:aryAlImage];
_arrImages = nil;
_arrImages = [NSMutableArray new];
_arrImages = [aryPhoto mutableCopy]; //mainImage, Asset, selected
[self setImageToScrollview:_arrImages];
}
#pragma mark - Display Image to ScrollView
-(void)setImageToScrollview:(NSMutableArray *)arrSetImage
{
// Remove all images from ScrollView and then add new one
for(id sender in _scrImageDisplay.subviews)
[sender removeFromSuperview];
_scrImageDisplay.pagingEnabled = FALSE;
CGFloat height_width = CGRectGetHeight(_scrImageDisplay.frame);
NSInteger numberOfImages = arrSetImage.count;
NSLog(@"Size of array is %ld",(long)numberOfImages);
CGFloat xOrigin = 0;
for (int i = 0 ; i < numberOfImages ; i++)
{
xOrigin += 3;
CGRect rect = CGRectMake(xOrigin, 0,height_width,height_width);
UIImageView *Arrimage = [[UIImageView alloc] initWithFrame:rect];
Arrimage.image = [[arrSetImage objectAtIndex:i] valueForKey:@"mainImage"];
NSLog(@"Image data is %@",Arrimage);
Arrimage.contentMode = UIViewContentModeScaleAspectFill;
Arrimage.clipsToBounds = YES;
[_scrImageDisplay addSubview:Arrimage];
xOrigin += height_width;
}
_scrImageDisplay.contentSize = CGSizeMake(xOrigin, height_width);
}
看来，行'UIImage * image = [self.arrImages objectAtIndex：imagecount];'是造成这个问题。你可以检查是这种情况吗？如果是，'[self.arrImages objectAtIndex：imagecount];'是一个'NSDictionary'，而不是'UIImage'对象。你可以登录'[self.arrImages objectAtIndex：imagecount];'？ – Larme
实际上，我也认为这行是导致问题，arrImages包含其中的所有图像。 @Larme –
Log'[self.arrImages objectAtIndex：imagecount];'，这是'NSDictionary'。我不知道你是如何填充'self.arrImages'，但这应该是问题。 – Larme
