Crash when calling cancelCurrentImageLoad on UIIMageView

[Kry256]

From the last update, when I call cancelCurrentImageLoad from my UIIMageView the app crashes with this message
-[UIImageView sd_cancelImageLoadOperationWithKey:]: unrecognized selector sent to instance 0x172490b0
Also this metho seems to be deprecated, but SDWebImage suggest me to replace as follows
cancelCurrentImageLoad' is deprecated: Use cancelCurrentImageLoad.
Think this one is only a typing error.

I'm having the exact same problem here.

@Kry256
its a typo mistake like you said...
it should say "Use sd_cancelCurrentImageLoad" instead

however i do not get the crash you suggested.

In order to resolve this crash, you need to import the newly added files:

UIView+WebCacheOperation.h
UIView+WebCacheOperation.m
UIImageView+HighlightedWebCache.h
UIImageView+HighlightedWebCache.m

I can't reproduce the crash using the demo project. I don't see why a crash because of missing imports. Could you provide more details? Does your copy of SDWebImage contain the UIView+WebCacheOperation class?

[bpoplauschi]

BTW, fixed the deprecated misspell with 30e034d

I can confirm that this only occurs when the UIView+WebCacheOperation.{h,m} are not included in the project. Works perfectly fine when they are included.

I have tried it inside a clean project. I have all the new classes correctly imported. Basically it happens that when I try to load an image using:
[imageView sd_setImageWithURL:__MyURL__ placeholderImage:[UIImage imageNamed:@"placeholder.png"] options:SDWebImageRetryFailed];

Then it will jump inside

- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletionBlock)completedBlock {

And as the first instruction of the method it calls

[self sd_cancelCurrentImageLoad];

The call make SDWebImage jumps into

- (void)sd_cancelCurrentImageLoad { [self sd_cancelImageLoadOperationWithKey:@"UIImageViewImageLoad"]; }

And here the crash happens with this message

-[UIImageView sd_cancelImageLoadOperationWithKey:]: unrecognized selector sent
to instance 0x1780ade0
Terminating app due to uncaught exception 'NSInvalidArgumentException'

[mythodeia]

@Kry256 the demo project has a scenario like that. when you go into the details view it loads the image by calling the sd_setImageWithURL which in turns calls sd_cancelCurrentImageLoad which successfully cals the sd_cancelImageLoadOperationWithKey inside the UIView+WebCacheOperation.m file.
no crash for me with the demo.
can you replicate it there?

[bpoplauschi]

There must be an issue with your project (either doesn't properly include the UIView+WebCacheOperation files or it has an issue loading categories (might be missing force_load or load_all flags)). Please try using our demo project. Also, on the clean project you set up, check if the UIView+WebCacheOperation files exist.

[bpoplauschi]

I just created a test single-view project where I installed SDWebImage via cocoapods

platform :ios, '6.1'
pod 'SDWebImage', :head

Ran sd_setImageWithUrl: and everything went smoothly.

[Kry256]

Sorry for the late in answer. In the sample project I wasn't able to reproduce this issue, however with the last commit cd4b925 everything came back to work well

[bpoplauschi]

Ok @Kry256, thanks for checking. Will close this one. Please reopen if you still encounter this issue.

[valentinradu]

Sorry for the extra late reply. I can confirm, my problem was the fact that after pulling the new version I didn't imported the right categories. Thanks for this cool class. (As a side question, why did you prefixed your methods with sd_? Just curious.)

[bpoplauschi]

@valentinradu we prefixed with sd_ to avoid naming collisions with libraries like AFNetworking (which also has an UIImageView category with imageWithURL:... methods. It's kind off having a namespace, since Obj-C doesn't support one built-in.

@bpoplauschi Sorry, but i still have this problem.

[coryhymel]

I am having this issue again as well. I installed using cocoapods and the methods show up as valid but when running I get unrecognized selector . These items are included in the pod file so everything should be there.

UIView+WebCacheOperation.h
UIView+WebCacheOperation.m
UIImageView+HighlightedWebCache.h
UIImageView+HighlightedWebCache.m

The only thing that may be causing this is that I had SDWebImage added originally by dragging the files in and setup the project environment for it. I removed all the old files, removed the other linker flags then ran the pod install. Any suggestions?

Also, that is weird is that setImageWithURL works fine??

[qiang437587687]

Just as @brynbodaylee and @coryhymel said check your SDWebImage include it or not ?? UIView+WebCacheOperation.h
UIView+WebCacheOperation.m
UIImageView+HighlightedWebCache.h
UIImageView+HighlightedWebCache.m
I slove this Issue add it to the progect!.
