Introduction

I am new to both iOS development and Stack Overflow, so forgive me if my post isn't perfect.

I also had this issue, and when I used the content insets for my UITableView it worked perfectly upon loading first, or when visiting it from my other tabs; however, if I navigated back to the view, it would have the extra "padding". I figured out a work around, so that my UITableView will be correctly placed every time.

The Issue

When you first load the UITableView, or tab to it, it needs the insets to correctly start the table below the navigation bar, but when you navigate back it does not need the insets, because for some reason, it correctly calculates for the placement of the UITableView. This is why you can get the extra padding.

The Solution

The solution involves using a boolean to determine whether you have navigated away, so that it can correctly determine whether it needs the content insets or not.

In -(void)viewDidLoad I set hasNavigatedFurther = NO. Then:

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    if (!hasNavigatedFurther) {
        self.tableView.contentInset = UIEdgeInsetsMake(64, 0, 0, 0);
    } else {
        self.tableView.contentInset = UIEdgeInsetsZero;
        //In order to allow visiting between tabs and retaining desired look
        hasNavigatedFurther = NO;
    }
}

In order to make this work, you need to set hasNavigatedFurther = YES just before your code that pushes another view onto the navigation stack.

-(void)btnTouched:(id)sender {
    hasNavigatedFurther = YES;
    NextViewController* nvc = [NextViewController new];
    [self.navigationController pushViewController:nvc animated:YES];
}
