在iOS 7中在viewDidLayoutSubviews应用中设置新的Tableview框架时崩溃

Question

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];
    if (employeeListModel.count > 0) {
        if ([employeeListModel count]*90 < self.view.bounds.size.height-64) {
            CGRect frame = self.empListTableView.frame;
            frame.size.height = [employeeListModel count]*90;
            self.empListTableView.frame = frame;
            //self.empListTableView.frame = CGRectMake(0, 0, self.view.bounds.size.width, [employeeListModel count]*90);
        } else {
            self.empListTableView.frame = self.view.bounds;
        }
    }
    [self.empListTableView layoutIfNeeded];
}

This method works perfectly in iOS 8 but crashes in iOS 7 , this crashes come from nowhere.

Answer 1

I got the same problem while manually adding constraints in code. In code, I was doing the following: From what I can tell, the issue is that when you disable translatesAutoresizingMaskIntoConstraints Solution: My solution was to move everything to the contentView.

    {
   [self.contentView addSubview:someView];
   [self.contentView addSubview:someOtherView];
   [self.contentView addConstraint:...];
}
