Dưới đây là thông báo lỗi tôi nhận được trong khu vực gỡ lỗi. Nó chạy tốt và không có gì sai ngoại trừ việc tôi nhận được lỗi này. Điều này sẽ ngăn táo chấp nhận ứng dụng? Làm thế nào để tôi sửa chữa nó?

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)
(
"<NSAutoresizingMaskLayoutConstraint:0x887d630 h=--& v=--& V:[UIButtonLabel:0x886ed80(19)]>",
"<NSAutoresizingMaskLayoutConstraint:0x887d5f0 h=--& v=--& UIButtonLabel:0x886ed80.midY == + 37.5>",
"<NSAutoresizingMaskLayoutConstraint:0x887b4b0 h=--& v=--& V:[UIButtonLabel:0x72bb9b0(19)]>",
"<NSAutoresizingMaskLayoutConstraint:0x887b470 h=--& v=--& UIButtonLabel:0x72bb9b0.midY == - 0.5>",
"<NSLayoutConstraint:0x72bf860 V:[UILabel:0x72bf7c0(17)]>",
"<NSLayoutConstraint:0x72c2430 UILabel:0x72bfad0.top == UILabel:0x72bf7c0.top>",
"<NSLayoutConstraint:0x72c2370 UILabel:0x72c0270.top == UILabel:0x72bfad0.top>",
"<NSLayoutConstraint:0x72c22b0 V:[UILabel:0x72bf7c0]-(NSSpace(8))-[UIButton:0x886efe0]>",
"<NSLayoutConstraint:0x72c15b0 V:[UILabel:0x72c0270]-(NSSpace(8))-[UIRoundedRectButton:0x72bbc10]>",
"<NSLayoutConstraint:0x72c1570 UIRoundedRectButton:0x72bbc10.baseline == UIRoundedRectButton:0x7571170.baseline>",
"<NSLayoutConstraint:0x72c21f0 UIRoundedRectButton:0x7571170.top == UIButton:0x886efe0.top>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x72bf860 V:[UILabel:0x72bf7c0(17)]>
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.
