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！！

 1 #pragma mark- 修改头像上传后保存
 2 -(void)uploadMyIco
 3 {
 4     //NSString *fileName = @"myico.jpg";
 5     UIImage *image1 = self.headImageVie.image;
 6
 7     NSData *data;
 8     float v = image1.size.width / 240;
 9     CGSize newSize = CGSizeMake(image1.size.width / v, image1.size.height / v);
10     UIGraphicsBeginImageContext(newSize);
11     [image1 drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
12     UIImage *scaleImage  = UIGraphicsGetImageFromCurrentImageContext();
13     UIGraphicsEndImageContext();
14     data = UIImageJPEGRepresentation(scaleImage, 0.8);
15     UIImage *image = [UIImage imageWithData:data];
16     UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil );
17     NSString *fileNamess =[self createImgFileName];
18     NSString* filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:fileNamess];
19     [data writeToFile:filePath atomically:NO];
20     NSMutableArray *imageArray = [[NSMutableArray alloc]init];
21     [imageArray addObject:[NSDictionary dictionaryWithObject:filePath forKey:@"file"]];
22     self.request = nil;
23     requestType = 2;
24     self.request = [UPRequest uploadPhotoInfo1:@"member/updatePhoto" image:imageArray keyName:@"file" delegate:self params:nil];
25     [SKProgressView ShowHudInView:self.view withTag:2001];
26 }

29 {
30     static int seedNum = 0;
31     if(seedNum >= 1000)
32         seedNum = 0;
33     seedNum++;
34
35     NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
36     [dateFormatter setDateFormat:@"yyyyMMddHHmmss"];
37
38     NSString *currentDateStr = [dateFormatter stringFromDate:[NSDate date]];
39    // [dateFormatter release];

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