How to Use SDWebImageManager in CCLayer

How to Use SDWebImageManager in CCLayer
1. In the header file

# Import "SDWebImageManager. h"

CCLayer must be implemented in the class definition

SDWebImageManagerDelegate.

Define and create

UIImageView * m_headImage;

2. Start downloading Avatar

- (void) upDateUserAvatar:(std::string) strAvatar{    if (strAvatar.length()<=0)     {        return  ;    }        NSString  * nsStrAvatar=[NSString  stringWithCString:strAvatar.c_str() encoding:NSUTF8StringEncoding];                if ([nsStrAvatar length] != 0)     {        SDWebImageManager* wim = [SDWebImageManager sharedManager];        [wim cancelForDelegate:self];        NSURL* url = [NSURL URLWithString:nsStrAvatar];        UIImage* cachedImage = [wim imageWithURL:url];        if (cachedImage)         {            m_headImage.image=cachedImage;        }         else         {            [wim downloadWithURL:url delegate:self];        }}}

3. Pair
SDWebImageManagerDelegate implementation code

//SDWebImageManagerDelegate  delegate  implement- (void)webImageManager:(SDWebImageManager *)imageManager didFinishWithImage:(UIImage *)image{    UNUSED(imageManager);        m_headImage.image=image;}- (void)webImageManager:(SDWebImageManager *)imageManager didFailWithError:(NSError *)error{    UNUSED(imageManager);    UNUSED(error);}

4. Cancel download in OnExit

-(Void) onExit {// cancel the download request submitted by self [[SDWebImageManager sharedManager] cancelForDelegate: self]; [super onExit];}
