我使用SnapKit到約束添加到圖片我有一個UIViewController錯誤swift2約束SnapKit
我有這樣的代碼：
imagenPrincipal.contentMode = .ScaleToFill
let URL = NSURL(string: oferta!.imagen)!
let placeholderImage = UIImage(named: "placeholder")!
imagenPrincipal.sd_setImageWithURL(URL, placeholderImage: placeholderImage, completed: nil)
let altoNuevo = 120.0
let anchoNuevo = 230.0
print(imagenPrincipal.frame.size.height)//->140.0
imagenPrincipal.frame.size.height = CGFloat(altoNuevo)
print(imagenPrincipal.frame.size.height)//->120.0
imagenPrincipal.snp_makeConstraints { (make) -> Void in
make.center.equalTo(self.view)
make.height.equalTo(imagenPrincipal.frame.size.height)
}
的問題是，我不將圖像大小調整爲大小我想和控制檯顯示我這個錯誤，它不是：
2016-07-07 13:12:44.652 TestApp[12517:197564] 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.
(
"<_UILayoutSupportConstraint:0x7f84297c21d0 V:[_UILayoutGuide:0x7f84295427b0(0)]>",
"<_UILayoutSupportConstraint:0x7f84297c3af0 V:|-(0)-[_UILayoutGuide:0x7f84295427b0] (Names: '|':UIView:0x7f84295e36b0)>",
"<NSLayoutConstraint:0x7f8429719520 V:[_UILayoutGuide:0x7f84295427b0]-(5)-[UIImageView:0x7f84297789e0]>",

"<NSLayoutConstraint:0x7f84295f9480 'UIView-Encapsulated-Layout-Height' V:[UIView:0x7f84295e36b0(568)]>"
)
Will attempt to recover by breaking constraint
<SnapKit.LayoutConstraint:[email protected]/Users/usuario/Swift/TestApp/TestAppV1/TestViewController.swift#62 UIImageView:0x7f84297789e0.height == 50.0>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
任何可能的解決方案？
我使用另一個庫的約束？
謝謝！
