ios6自動佈局約束

Question

我試圖弄清楚如何使用UIViewController（在UITabBarController裏面的UINavigationController）的約束... 千言萬語，這就是我正在做的事情.. 。

其實，第一個是100px的高度無論是定位，第二個是廣告（在橫向縱向和32PX所以50像素），最後的tableView將採取休息。

到目前爲止，這裏是我的代碼：

PMMainProfilHeader *profilHeader = [[PMMainProfilHeader alloc] init]; 
    [self.view addSubview:profilHeader]; 
    [profilHeader release]; 

    UIView *adTest = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)]; 
    adTest.backgroundColor = [UIColor redColor]; 
    [self.view addSubview:adTest]; 
    [adTest release]; 

    _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; 
    [self.view addSubview:_tableView]; 
    [_tableView release]; 

    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-0-[profilHeader]-0-|" 
                     options:0 
                     metrics:nil 
                     views:NSDictionaryOfVariableBindings(profilHeader)]]; 
    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-0-[adTest]-0-|" 
                     options:0 
                     metrics:nil 
                     views:NSDictionaryOfVariableBindings(adTest)]]; 
    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-0-[_tableView]-0-|" 
                     options:0 
                     metrics:nil 
                     views:NSDictionaryOfVariableBindings(_tableView)]]; 
    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-0-[profilHeader]-0-[adTest]-0-[_tableView]-0-|" 
                     options:0 
                     metrics:nil 
                     views:NSDictionaryOfVariableBindings(profilHeader, adTest, _tableView)]]; 

但是，當然，這是行不通的......，我不能夠告訴爲什麼，當我簡歷調試一對夫婦的時候，我得到這個來自調試器的評論塊：

    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it.

感謝您閱讀整個（巨大）文章！希望有人知道爲什麼它不起作用！

Answer 1

好吧，我找到了答案......

我只好打電話setTranslatesAutoresizingMaskIntoConstraints爲我使用的限制，每個視圖：

[profilHeader setTranslatesAutoresizingMaskIntoConstraints:NO]; 
[adTest setTranslatesAutoresizingMaskIntoConstraints:NO]; 
[_tableView setTranslatesAutoresizingMaskIntoConstraints:NO]; 

希望它可以幫助別人......
