NSURL *url=[NSURL URLWithString:@"http://www.gourmet7.com/auth"];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:url];
    [request setHTTPMethod:@"POST"];

这只能是一个疯狂的猜测，但是因为你的代码编译得很好，我认为你的目标是低于8.0的iOS版本。

不幸的是，<LinearLayout xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.stack.line.CustomView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/custom" /> </LinearLayout>属性仅在8.0之后可用。因此，您必须将最低iOS版本提升至至少8.0或使用其他机制。
