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 / 240;
    CGSize newSize = CGSizeMake(image1.size.width / v, image1.size.height / v);
    UIGraphicsBeginImageContext(newSize);
    [image1 drawInRect:CGRectMake(0, 0, 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 = 2;
    self.request = [UPRequest uploadPhotoInfo1:@"member/updatePhoto" image:imageArray keyName:@"file" delegate:self params:nil];
    [SKProgressView ShowHudInView:self.view withTag:2001];
}

- (NSString *)createImgFileName
{
    static int seedNum = 0;
    if(seedNum >= 1000)
        seedNum = 0;
    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, 1);
        fileName = @"departMentLogo.png";
    } else {
        data = UIImagePNGRepresentation(image1);
        fileName = @"departMentLogo.jpg";
    }
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:fileName];
    [data writeToFile:fullPathToFile atomically:NO];
    
    NSMutableArray *array = [NSMutableArray arrayWithCapacity:0];
    [array addObject:[NSDictionary dictionaryWithObject:[NSNumber numberWithInteger:1] 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 = 2;
    self.request = [UPRequest uploadPhotoInfo1:@"dept/uploadPhoto" image:imageArray keyName:@"file" delegate:self params:array];
}
