Ensure that AFNetworking+UIImageView.m (or more likely, all AFNetworking implementation files) has been added to your target.
Click on AFNetworking+UIImageView.m, and select your target under "Target Membership" in the right window.

I have the following function which loads an image using the new PHPickerViewController:
- (void) picker:(PHPickerViewController *)picker didFinishPicking:(NSArray<PHPickerResult *> *)results
{
PHPickerResult *result = [results firstObject];
if (result)
{
[result.itemProvider loadObjectOfClass:[UIImage class] completionHandler:^(__kindof id<NSItemProviderReading> _Nullable object, NSError * _Nullable error)
{
dispatch_async(dispatch_get_main_queue(),
^{
if (!error)
{
[self pickerControllerDidFinishPickingWithImage:(UIImage *)object];
}
else
{
[self pickerControllerDidFinishWithError];
}
});
}];
}
}
I want to avoid using loadObjectOfClass because I don't want the image to load asynchronously. So I opted to use loadItemForTypeIdentifier instead and did the following:
[result.itemProvider loadItemForTypeIdentifier:#"public.image" options:nil completionHandler:^(__kindof id<NSItemProviderReading> _Nullable object, NSError * _Nullable error)
{
dispatch_async(dispatch_get_main_queue(),
^{
if (!error)
{
[self pickerControllerDidFinishPickingWithImage:(UIImage *)object];
}
else
{
[self pickerControllerDidFinishWithError];
}
});
}];
However, when I run this code I am getting:
ncaught exception 'NSInvalidArgumentException', reason: '-[NSURL
imageOrientation]: unrecognized selector sent to instance
0x600001ce5920' terminating with uncaught exception of type
NSException
I am not that great with blocks and this is my first time using a UTI so I'm wondering, what am I doing wrong here? Is it even possible to accomplish what I'm trying to accomplish, i.e. pull a UIImage out using loadItemForTypeIdentifier? Am I getting the syntax wrong?
I've just updated Afnetworking 1 to 2.1 and app started to crash. there was no problem at AF 1.0. How can i solve this problem?
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[API initWithBaseURL:]: unrecognized selector sent to instance 0xa3e6810'

I am working on an app which is image downloading. Images are of different sizes. I want to download image async and update table view when image downloading. Also need to clear cache on a time interval.
Please suggest me how to implement. I have seen SDwebimagecache but it is crashing on image downloading.
I hope it's can help you. I use SDWebImage with my all (ARC)projects.
using :
add your viewcontroller : #import "UIImageView+WebCache.h"
[yourImageView setImageWithURL:[NSURL URLWithString:#"ImageUrl"]];
you need to add MapKit and ImageIO to the project. if you didn't add
To do that:
Click on the project at the top of the project navigator in Xcode
Select the 'Build Phases' tab.
Open up the 'Link Binary with Libraries' box.
Click the '+'.
Add MapKit and ImageIO frameworks.
I have used the core data and AFNetworking to achieve the same thing, find below my code
UserBasicInfo* userBasicInfo = [[UserBasicInfo findByAttribute:#"userId" withValue:#(chatUser)] objectAtIndex:0];;
if (userBasicInfo.userImage == nil) {
__weak LGMessageBoxCell *weakCell = cell;
[cell.userImage setImageWithURLRequest:[[NSURLRequest alloc] initWithURL:[NSURL URLWithString:userBasicInfo.imageUrl]]
placeholderImage:[UIImage imageNamed:#"facebook-no-user.png"]
success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
weakCell.userImage.image = image;
[weakCell setNeedsLayout];
[MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {
UserBasicInfo* userBasicInfo = [[UserBasicInfo findByAttribute:#"userId" withValue:#(chatUser) inContext:localContext] objectAtIndex:0];
userBasicInfo.userImage = UIImagePNGRepresentation(image);
} completion:^(BOOL success, NSError *error) {
NSLog(#"%#",[error localizedDescription]);
}];
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
}];
} else {
cell.userImage.image = [UIImage imageWithData:userBasicInfo.userImage];
}
Parsing simple JSON with AFNetworking is well documented and seems very straight forward. What I'm trying to do is parse JSON from Instagram, which is many levels deep into an array where I can pull the images and insert into a CollectionView. Right now I'm stuck. My simple code returns everything in a single text block, and not what I need at all. What I'm trying to grab is outlined in Red. If I grab 10 images, I really want those all in an array. At that point I can grab the actually images and display them. Right now I'm stuck.
Find all images that are tagged Snow:
https://api.instagram.com/v1/tags/snow/media/recent?access_token=836379.f59def8.fd07b9ba8ea440188dc56d2763bbf6c2
Code that just return a string of image names, which is not want I want at all.
-(void)viewDidLoad {
NSLog(#">>> Entering %s <<<", __PRETTY_FUNCTION__);
[super viewDidLoad];
NSString *path = #"https://api.instagram.com/v1/tags/snow/media/recent?access_token=836379.f59def8.fd07b9ba8ea440188dc56d2763bbf6c2";
NSLog(#"path %#", path);
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:path]];
AFJSONRequestOperation *operation =
[AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSString *image = [[[[JSON valueForKey:#"data"]valueForKey:#"images"]valueForKey:#"low_resolution"]valueForKey:#"url"];
NSLog(#"%#", image);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){
// NSLog(#"There was a problem: %#", [error localizedDescription]);
}];
[operation start];
//NSDictionary *dict = [imagesArry objectAtIndex:0];
}
This is what I get:

Just seems like I'm not approaching it right, is it that simple? One line get grab all my Instagram images links? Hmmmm, it does look like they are seperated by ",". Could it be that simple?
NSString *image = [[[[JSON valueForKey:#"data"]valueForKey:#"images"]valueForKey:#"low_resolution"]valueForKey:#"url"];
UPDATE:
Ok, almost. This is a bit strange, seems very straight forward, trying to split the array by "," yet i am sure I'm working on a string:
NSArray *listItems = [image componentsSeparatedByString:#","];

Thanks Hot Licks. Just because I say it's a NSTRING means zilch. I am really returning an array.

hi i'm the developer of the application.
The problem is that running on Xcode 4.5 is correct but just running on iphone device it wont work..
