Question

我正在以这种方式使用AWS SDK

属性声明：

@property (nonatomic, strong)AWSStaticCredentialsProvider *credentialsProvider;
@property (nonatomic, strong)AWSServiceConfiguration * configuration;
@property (nonatomic, strong)AWSS3 *s3;
@property (nonatomic, strong) AWSS3PutObjectRequest *putrequest;

以这种方式实施

  AccessKeys * accessKeys = [ECSGlobals sharedInstance].accessKeys;
    self.credentialsProvider = [AWSStaticCredentialsProvider    credentialsWithAccessKey:accessKeys.accessKeyId secretKey:accessKeys.secretAccessKey];
    self.configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1    credentialsProvider:self.credentialsProvider];
    self.s3 = [[AWSS3 alloc] initWithConfiguration:self.configuration];
    self.putrequest = [AWSS3PutObjectRequest new];


NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:imageName];
NSData *imageData = UIImageJPEGRepresentation(image, 0.2);
[imageData writeToFile:savedImagePath atomically:NO];


long long fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:savedImagePath error:nil][NSFileSize] longLongValue];


self.putrequest.bucket = bucketName;
self.putrequest.key = imageName;
self.putrequest.contentType = @"image/jpeg";
self.putrequest.body = [NSURL fileURLWithPath:savedImagePath];
self.putrequest.contentLength =  [NSNumber numberWithLongLong:fileSize];
[[self.s3 putObject:self.putrequest] continueWithBlock:^id(BFTask *task) {
    NSLog(@"Amazon error : %@", [task error]);
    return nil;
}];

但我崩溃了

[CFError retain]：消息发送到解除分配的实例0x7f2daff0

我检查过所有属性都很强大。不知道为什么我会遇到这个崩溃。

我找到了解决方案。我们正在将此问题作为一些保存的图像路径在使用前变为零的方式。因此没有图像数据发送到AWS。

修复此问题后，图片上传成功。

使用AWSS3PutObjectRequest获得崩溃
