iOS开发之上传图片视频到服务器

响应点击事件的方法：

这里我是用的系统的相册，没有自定义。也没用进行对应的压缩。需要的朋友需要自行解决了。但这些代码保证能给上传成功。

-(void)photoBtnSelecoed{

NSLog(@"图片");

UIImagePickerController *picker = [[UIImagePickerController alloc]init];

picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

picker.delegate = self;

下句代码是系统相册里图片跟视频可以共同显示出来

picker.mediaTypes = @[(NSString *)kUTTypeMovie,(NSString *)kUTTypeImage];

picker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

picker.allowsEditing = YES;

[self presentViewController:picker animated:YES completion:nil];

}

具体获取选择的图片或视频进行上传

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

[picker dismissViewControllerAnimated:YES completion:nil];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

manager.requestSerializer = [AFHTTPRequestSerializer serializer];

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

if ([mediaType isEqualToString:@"public.image"]) {

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];

[parameters setObject:self.access_key forKey:@"access_key"];

[parameters setObject:@"12" forKey:@"receive_u_id"];

[parameters setObject:@"2" forKey:@"msg_type"];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",

@"text/html",

@"image/jpeg",

@"image/png",

@"application/octet-stream",

@"text/json",

nil];

[manager POST:[NSString stringWithFormat:@"%@%@",SERVER_URL,MSG_MESSAGE_SEND] parameters:parameters constructingBodyWithBlock:^(id_Nonnull formData) {

UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];

NSData *data = UIImagePNGRepresentation(image);

//上传的参数(上传图片，以文件流的格式)

[formData appendPartWithFileData:data

name:@"file"

fileName:@"gauge.png"

mimeType:@"image/png"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {

NSLog(@"上传成功");

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

NSLog(@"上传失败%@",error);

}];

dispatch_async(dispatch_get_main_queue(), ^{

上传后立即刷新数据在主线程里

[self requestOtherMessageList];

});

} else if ([mediaType isEqualToString:@"public.movie"]){

NSLog(@"选择的视频");
