我正在制作一款需要与服务器通信的iPhone应用程序(S3)。但是,当我执行此代码时:
- (void)submit
{
dispatch_queue_t Q = dispatch_queue_create("Formula Submit", NULL);
dispatch_async(Q, ^{
NSMutableArray *formulas = [[NSArray arrayWithContentsOfURL:[NSURL URLWithString:@"https://urlremoved.com"]] mutableCopy];
if (!formulas)
{
formulas = [[NSMutableArray alloc] init];
}
[_data addEntriesFromDictionary:[[NSDictionary alloc] initWithObjectsAndKeys:self.explanationTextView.text, @"explanation", nil]];
[formulas addObject:_data];
AmazonS3Client *s3 = [[AmazonS3Client alloc] initWithAccessKey:@"Access Key Removed" withSecretKey:@"Secret Key Removed"];
S3PutObjectRequest *por = [[S3PutObjectRequest alloc] initWithKey:@"File Name Removed" inBucket:@"Bucket Name Removed"];
por.contentType = @"application/octet-stream";
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:formulas format:NSPropertyListBinaryFormat_v1_0 errorDescription:nil];
por.data = plistData;
[s3 putObject:por];
});
[self dismissModalViewControllerAnimated:YES];
}
我在控制台中收到此错误/警告:
void _WebThreadLockFromAnyThread(bool), 0x20150be0: Obtaining the web lock from a thread other than the main thread or the web thread. UIKit should not be called from a secondary thread.
此消息似乎不会以任何方式影响应用程序性能。它成功上传到S3,没有明显的问题。
我很想知道,如果有办法让这条消息消失。
