使用AFNetWorking上传照片

1、照片选择完成

- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info

{

[pickerdismissViewControllerAnimated:YEScompletion:nil];

photo= [infoobjectForKey:UIImagePickerControllerEditedImage];

CGSizeimagesize =photo.size;

imagesize.height=imagesize.height*1024/imagesize.width;

imagesize.width=1024;

//对图片大小进行压缩--

photo= [ImageUtilimageWithImage:photoscaledToSize:imagesize];

[self.tableViewreloadData];

[selfimageUpToWebAction:photo];

}

2、上传照片

#pragma mark ----上传图片

-(void)imageUpToWebAction:(UIImage*)image

{

[selfshowMessage:@"头像上传中..."];

NSString*urlString = [NSStringstringWithFormat:@"%@/photoupload",addressUrl];

[managerPOST:urlStringparameters:nilconstructingBodyWithBlock:^(id formData) {

NSData*imageData =UIImageJPEGRepresentation(image,0.00001);

NSDateFormatter*formatter = [[NSDateFormatteralloc]init];

formatter.dateFormat=@"yyyyMMddHHmmss";

NSString*str = [formatterstringFromDate:[NSDatedate]];

NSString*fileName = [NSStringstringWithFormat:@"%@.jpg", str];

//上传图片，以文件流的格式

[formDataappendPartWithFileData:imageDataname:@"importFile"fileName:fileNamemimeType:@"image/jpeg"];

}success:^(AFHTTPRequestOperation*operation,idresponseObject) {

[selfhideHUD];

NSString*status=[responseObjectobjectForKey:@"status"];

NSString*message=[responseObjectobjectForKey:@"message"];

if([statusboolValue]){

_urlString= [NSStringstringWithString:message];

[selfsaveUserImage:message];

}else{

[selfshowError:message];

}

}failure:^(AFHTTPRequestOperation*operation,NSError*error) {

[selfshowError:[error.userInfoobjectForKey:@"NSLocalizedDescription"]];

}];

}

3、压缩照片

//对图片尺寸进行压缩--

+(UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize

{

// Create a graphics image context

UIGraphicsBeginImageContext(newSize);

// Tell the old image to draw in this new

context, with the desired

// new size

[imagedrawInRect:CGRectMake(0,0,newSize.width,newSize.height)];

// Get the new image from the context

UIImage* newImage =UIGraphicsGetImageFromCurrentImageContext();

// End the context

UIGraphicsEndImageContext();

// Return the new image.

returnnewImage;

}

4、

AFHTTPRequestOperationManager*manager;

manager= [AFHTTPRequestOperationManagermanager];
