Question

当我尝试通过服务器获取图像时出现此错误这是我通过服务器获取图像的代码：

-(void)downloadThumbnailWithHeight:(NSInteger)height width:(NSInteger)width callback:(void (^)(UIImage*))callback {
    NSString* key = [NSString stringWithFormat:@"%ldx%ld", (long)width, (long)height];
    UIImage* __block thumbnail = [_thumbnails objectForKey:key];
    if (thumbnail) { callback(thumbnail); return; }
    HttpRequest* request = [HttpRequest requestWithRelativePath:[NSString stringWithFormat:@"/api/v1/incident/%@/resize?height=%d&width=%d",self.uuid, (int)height, (int)width]];
    [HttpResponse processAsynchronousRequest:request onCompletion:^(HttpResponse* response) {
        dispatch_async(dispatch_get_main_queue(), ^{
            thumbnail = [UIImage imageWithData:response.responseData];
            if (!thumbnail) thumbnail = [UIImage imageNamed:@"gray_thumbnail_background.png"];
            [_thumbnails setObject:thumbnail forKey:key];
            callback(thumbnail);
        });
    }];
}

在我在stackoverflow中提出这个问题之前，我已经尝试在我的info.plist中添加它。这是我的plsit：

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>
    <key>NSLocationAlwaysUsageDescription</key>
    <string>To Find out your location</string>
    <key>NSLocationWhenInUseUsageDescription</key>
    <string>To Find out your location</string>
    <key>CFBundleIdentifier</key>
    <string>com.abc.def</string>
    <key>CFBundleExecutable</key>
    <string>${EXECUTABLE_NAME}</string>
    <key>CFBundleInfoDictionaryVersion</key>
    <string>6.0</string>
    <key>CFBundleShortVersionString</key>
    <string>1.0</string>
    <key>CFBundleVersion</key>
    <string>1</string>
    <key>CFBundleDevelopmentRegion</key>
    <string>en</string>
    <key>CFBundlePackageType</key>
    <string>BNDL</string>
    <key>CFBundleSignature</key>
    <string>????</string>
</dict>
</plist>

但它仍无法正常工作启动应用程序时，IT会给我以下错误：

App Transport Security已阻止明文HTTP（http：//）资源负载，因为它是不安全的。可以通过配置临时例外你的应用程序的Info.plist文件。

请帮帮我，因为我已经花了两大部分时间来解决这个问题在此先感谢。

如果由于某些原因，您更喜欢使用NSAllowsArbitraryLoads密钥来忽略安全限制，则必须将其放在NSAppTransportSecurity字典中，因为只需将您的字典放在NSAppTransportSecurity密钥下。

<key>NSAppTransportSecurity</key>  
<dict>  
     <key>NSAllowsArbitraryLoads</key><true/>  
</dict>

但不建议这样做，可能会导致Apple拒绝您的应用。 Apple非常清楚，他们打算拒绝使用此标志的应用程序，而无需特殊原因。

更好的解决方案可能是向特定域添加例外。

参考：https://developer.apple.com/library/prerelease/ios/technotes/App-Transport-Security-Technote/index.html

您的NSAppTransportSecurity部分可能如下所示：

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
     <key>yourdomain.com</key>
     <dict>
       <key>NSIncludesSubdomains</key>
       <true/>
       <key>NSExceptionAllowsInsecureHTTPLoads</key>
       <true/>
       <key>NSExceptionMinimumTLSVersion</key>
       <string>TLSv1.2</string>
     </dict>
   </dict>
</dict>
