AFNetworking请求中含有中文时程序崩溃
AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager manager];
[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
//
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//
}];
出现error：
Assertion failure in -[AFHTTPRequestSerializer requestWithMethod:URLString:parameters:error:]
需要处理urlString的编码
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
