Question

问题在于：

我想在完成从imagepicker中选择图片后立即上传图片。
所以，我把我的代码用于在imagepicker委托方法中使用afnetworking上传图片。

但它没有任何反应。

//set the imageview to current image after choosing
profilePic.image = image;

//dismiss the imagepicker
[picker dismissModalViewControllerAnimated:YES];

//start upload image code
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        @"steventi1901", @"username",
                        UIImagePNGRepresentation(profilePic.image), @"profile_pic",
                        nil];

 AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:updateProfile];
NSData *imageToUpload = UIImagePNGRepresentation(profilePic.image);

NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"PUT" path:@"" parameters:params
                                            constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData: imageToUpload name:@"file" fileName:@"temp.png" mimeType:@"image/png"];
    //NSLog(@"dalem");
}];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *response = [operation responseString];
    NSLog(@"response: [%@]",response);

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

    if([operation.response statusCode] == 403){
        NSLog(@"Upload Failed");
        return;
    }
    NSLog(@"error: %@", [operation error]);

}];

[operation start];
//end upload image code

它确实没有回应，所以我不知道这个过程是否失败或成功。

使用Afnetworking上传图片的最佳方式。

请使用以下AFNetworking。

pod＆＃39; AFNetworking＆＃39;，＆＃39;〜＆gt; 2.5.4＆＃39;

//Create manager AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //parameters if any NSMutableDictionary *AddPost = [[NSMutableDictionary alloc]init]; [AddPost setValue:@"Addparma" forKey:@"param"]; NSString * url = [NSString stringWithFormat:@"www.addyourmainurl.com"];; NSLog(@"AddPost %@",AddPost); [manager POST:url parameters:[AddPost copy] constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { //add image data one by one for(int i=0; i<[Array count];i++) { UIImage *eachImage = [Array objectAtIndex:i]; NSData *imageData = UIImageJPEGRepresentation(eachImage,0.5); [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"image%d",i] fileName:[NSString stringWithFormat:@"image%d.jpg",i ] mimeType:@"image/jpeg"]; } } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Success: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];

您是否设置了选择器的委托？

[yourPicker setDelegate:self]

使用AFnetworking上传图像没有任何响应
