UIViewController (UINavigationController 内にある UITabBarController 内) で制約を使用する方法を理解しようとしています...千語以上、これが私がやろうとしていることです...
実際には、最初のものは向きに関係なく 100 ピクセルの高さで、2 番目は広告 (つまり、縦向きで 50 ピクセル、横向きでは 32 ピクセル) で、最後に残りの部分を占める tableView です。
これまでのところ、私のコードは次のとおりです。
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)]];
しかし、もちろん機能しません...そして、デバッグを数回再開すると、デバッガーから次のコメントブロックが表示される理由がわからない:

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. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Break on objc_exception_throw to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
