我正在尝试使用NSURLConnection下载JSON,但是除非我强制应用暂停几秒钟,否则我获得的数据将不完整。它总是大约2600字节,我的响应应该在70000左右。
任何线索为什么会这样?
谢谢
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
_responseData = [[NSMutableData alloc] init];
//sleep(10);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[_responseData appendData:data];
[self getDataJSON: _responseData];
}
最佳答案
didReceiveData在接收数据时被多次调用
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[_responseData appendData:data];
}
您必须等到它完成接收数据
- (void)connectionDidFinishLoading:(NSURLConnection*)connection
{
[self getDataJSON: _responseData];
}
关于ios - didReceiveData没有获取所有数据,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/20095234/
