ios-上传图片到后台

做第一个项目时，有个版块的个人信息的编辑涉及到头像修改，老大说项目里有通用的代码，让我自己去找。总算找到，搞了许久才弄好，看来理解能力还需要提高啊！！

 #pragma mark- 修改头像上传后保存
 -(void)uploadMyIco
 {
     //NSString *fileName = @"myico.jpg";
     UIImage *image1 = self.headImageVie.image;    

     NSData *data;
     float v = image1.size.width / ;
     CGSize newSize = CGSizeMake(image1.size.width / v, image1.size.height / v);
     UIGraphicsBeginImageContext(newSize);
     [image1 drawInRect:CGRectMake(, , newSize.width, newSize.height)];
     UIImage *scaleImage  = UIGraphicsGetImageFromCurrentImageContext();
     UIGraphicsEndImageContext();
     data = UIImageJPEGRepresentation(scaleImage, 0.8);
     UIImage *image = [UIImage imageWithData:data];
     UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil );
     NSString *fileNamess =[self createImgFileName];
     NSString* filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:fileNamess];
     [data writeToFile:filePath atomically:NO];
     NSMutableArray *imageArray = [[NSMutableArray alloc]init];
     [imageArray addObject:[NSDictionary dictionaryWithObject:filePath forKey:@"file"]];
     self.request = nil;
     requestType = ;
     self.request = [UPRequest uploadPhotoInfo1:@"member/updatePhoto" image:imageArray keyName:@"file" delegate:self params:nil];
     [SKProgressView ShowHudInView:self.view withTag:];
 }

 - (NSString *)createImgFileName
 {
     static int seedNum = ;
     if(seedNum >= )
         seedNum = ;
     seedNum++;

     NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
     [dateFormatter setDateFormat:@"yyyyMMddHHmmss"];

     NSString *currentDateStr = [dateFormatter stringFromDate:[NSDate date]];
    // [dateFormatter release];

     NSString *file = [NSString stringWithFormat:@"temppics%@%03d.jpg", currentDateStr, seedNum];
     return file;
 }

部门logo修改是是参照写的〜

 #pragma mark- 图像上传保存
 - (void)uploadDepartmentLogo//上传部门logo图片
 {
     NSString *fileName = @"departMentLogo.jpg";
     UIImage *image1 = self.headImageView.image;
     NSData *data;
     if ( UIImagePNGRepresentation(image1) == nil )
     {
         data = UIImageJPEGRepresentation(image1, );
         fileName = @"departMentLogo.png";
     } else {
         data = UIImagePNGRepresentation(image1);
         fileName = @"departMentLogo.jpg";
     }
     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
     NSString *documentsDirectory = [paths objectAtIndex:];
     NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:fileName];
     [data writeToFile:fullPathToFile atomically:NO];

     NSMutableArray *array = [NSMutableArray arrayWithCapacity:];
     [array addObject:[NSDictionary dictionaryWithObject:[NSNumber numberWithInteger:] forKey:@"type"]];
     [array addObject:[NSDictionary dictionaryWithObject:self.deptId forKey:@"deptId"]];

     NSMutableArray *imageArray = [[NSMutableArray alloc]init];
     [imageArray addObject:[NSDictionary dictionaryWithObject:fullPathToFile forKey:@"file"]];//deptHead

     self.request = nil;
     requestType = ;
     self.request = [UPRequest uploadPhotoInfo1:@"dept/uploadPhoto" image:imageArray keyName:@"file" delegate:self params:array];
 }
