因為一些原因 SDWebImage 沒設(shè)置 User-Agent 所以自己設(shè)置一下
//設(shè)置 User-Agent
NSString *userAgent = @"";
userAgent = [NSString stringWithFormat:@"%@/%@ (%@; iOS %@; Scale/%0.2f)",
[[[NSBundle mainBundle] infoDictionary] objectForKey:(__bridge NSString *)kCFBundleExecutableKey] ?:
[[[NSBundle mainBundle] infoDictionary] objectForKey:(__bridge NSString *)kCFBundleIdentifierKey],
[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"] ?:
[[[NSBundle mainBundle] infoDictionary] objectForKey:(__bridge NSString *)kCFBundleVersionKey],
[[UIDevice currentDevice] model], [[UIDevice currentDevice] systemVersion],
[[UIScreen mainScreen] scale]];
if (userAgent) {
if (![userAgent canBeConvertedToEncoding:NSASCIIStringEncoding]) {
NSMutableString *mutableUserAgent = [userAgent mutableCopy];
if (CFStringTransform((__bridge CFMutableStringRef)(mutableUserAgent), NULL,
(__bridge CFStringRef)@"Any-Latin; Latin-ASCII; [:^ASCII:] Remove", false)) {
userAgent = mutableUserAgent;
}
}
[[SDWebImageDownloader sharedDownloader] setValue:userAgent forHTTPHeaderField:@"User-Agent"];
}
//調(diào)用示例
[img sd_setImageWithURL:[NSURL URLWithString:@"http://img3.imgtn.bdimg.com/it/u=17435921,1676944870&fm=21&gp=0.jpg"]
placeholderImage:[UIImage imageNamed:@"1"]
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
[img drawCircleImage1];
}];

//設(shè)置頭文件
[[SDWebImageDownloader sharedDownloader]
setValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"
