У меня есть настраиваемый UITableViewCell, и я пытаюсь Автокомпоновка в UILabel, потому что его текст может иметь любую длину, но я получаю эту ошибку:IOS, NSLayoutConstraint Выпуск
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.
2014-09-14 10:20:37.693 InstantForum[29658:60b] Unable to simultaneously satisfy constraints.
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)
(
"<NSLayoutConstraint:0x9aea2e0 V:|-(45)-[UILabel:0x9ae9f30] (Names: '|':UITableViewCellContentView:0x9ae9250)>",
"<NSLayoutConstraint:0x9aea330 V:[UILabel:0x9ae9f30(>=10)]>",
"<NSLayoutConstraint:0x9aea380 V:[UILabel:0x9ae9f30]-(NSSpace(20))-| (Names: '|':UITableViewCellContentView:0x9ae9250)>",
"<NSAutoresizingMaskLayoutConstraint:0x8c8a750 h=--& v=--& V:[UITableViewCellContentView:0x9ae9250(44)]>"
)
Will attempt to recover by breaking constraint

Это код в моей UITableViewCell , это где я установки на подвиды в клетке:
