我已經嘗試了很長時間,但由於約束問題不斷得到崩潰...如何正確設置此佈局的約束條件?
如何設置此佈局,使其適用於iPhone 3Gs,4和5以及iPad?
_______TOP OF SCREEN________
Table View should attach to top of screen and with 5 pixels to the Label below
flexible in height so it works on iPhone 5 and 6
____________________________
Label with fixed distance to table View above and button below
____________________________
Button with fixed distance to Label above and fixed distance to bottom of screen
____________________________
Bottom of screen
所以基本上所有的距離和高度是固定的,除了桌子的高度,應填寫無論是屏幕的上方和標籤
之間可每當我設置這樣的contstraints我不斷收到崩潰在iPhone 3的iOS 6.1:

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:0x1d1f2d70 h=-&- v=-&- UIView:0x1d1aac20.height == UITransitionView:0x1d174220.height - 20>",
"<NSLayoutConstraint:0x1d1c03b0 V:[UILabel:0x1c58f100(21)]>",
"<NSLayoutConstraint:0x1d1ce780 V:[UITableView:0x1cbd9000(469)]>",
"<NSLayoutConstraint:0x1c5aff30 V:[UIButton:0x1d1d1bb0(44)]>",
"<NSLayoutConstraint:0x1d1c0030 V:|-(0)-[UITableView:0x1cbd9000] (Names: '|':UIView:0x1d1aac20)>",
"<NSLayoutConstraint:0x1d1921d0 V:[UILabel:0x1c58f100]-(1)-[UIButton:0x1d1d1bb0]>",
"<NSAutoresizingMaskLayoutConstraint:0x1c58e4d0 h=--- v=--- V:[UIWindow:0x1d002230(480)]>",
"<NSLayoutConstraint:0x1d1cd6c0 V:[UITableView:0x1cbd9000]-(NSSpace(8))-[UILabel:0x1c58f100]>",
"<NSLayoutConstraint:0x1d1ca370 V:[UIButton:0x1d1d1bb0]-(5)-| (Names: '|':UIView:0x1d1aac20)>",
"<NSAutoresizingMaskLayoutConstraint:0x1d172a90 h=--& v=-&- UITransitionView:0x1d174220.height == UIWindow:0x1d002230.height>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x1d1ce780 V:[UITableView:0x1cbd9000(469)]>
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.

完美 - 感謝您的幫助!順便說一下,有一種方法來檢查這些約束問題之前運行某種方式,讓他們顯示我更好的方式? – user387184 2013-03-17 06:30:29
我不認爲這些工具還支持這一點。約束的解決方案最終取決於運行時實際窗口的大小和方向,所以我不確定這些工具在編譯時能夠完全檢測到問題。但是在運行時,您會看到像您看到的異常,並且您還可以在運行時檢查不明確的約束。 – 2013-03-17 18:05:43
花了很多時間後,高度正是衝突的約束。萬分感謝! – Tomer 2013-07-13 03:44:24
