如果我需要发布堆栈中使用的方法中的代码,请让我知道这是否有用。(对不起,我以前从未真正处理过这类问题)来自awakeFromNib的描述: 由于无法保证从存档中实例化对象的顺序,因此您的初始化方法不应向层次结构中的其他对象发送消息。可以从awakeFromNib方法中安全地向其他对象发送消息。 通常,对于需要在设计时无法完成的额外设置的对象,可以实现awakeFromNib。例如,您可以使用此方法自定义任何控件的默认配置,以匹配用户首选项或其他控件中的值。您还可以使用它将单个控件恢复到应用程序的某些以前的状态 我不是100%确定,但强烈建议我搬家
[self.button setFrame:NSMakeRect(50, 10, 100, 100)];
到
方法。另外,您不应该忘记调用super的方法——在某些情况下,这可能是至关重要的。因此,您的最终代码应该如下所示:
@implementation AppDelegate
- (void)awakeFromNib{
[super awakeFromNib];
... non GUI initialization
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self.button setFrame:NSMakeRect(50, 10, 100, 100)];
}
@end
- (void)resizeWithOldSuperviewSize:(NSSize)oldSize {};
更新:
谢谢你的来电。您的视图似乎已自动调整大小。您应该检查autoresizingMask和auto layout constraints,因此我通过对视图进行子类化并覆盖
-resizeWithOldSuperviewSize:
来停止视图的大小调整,只需执行以下操作:
@implementation AppDelegate
- (void)awakeFromNib{
[super awakeFromNib];
... non GUI initialization
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self.button setFrame:NSMakeRect(50, 10, 100, 100)];
}
@end
- (void)resizeWithOldSuperviewSize:(NSSize)oldSize {};
使用OldSuperViewSize:替换
Resize的内容的另一种方法是通知自动布局系统您不希望调整NSView的大小。这将使NSView保持在以编程方式指定的原点,从而保持对interface builder的重写完好无损。您可以通过以下方式执行此操作:
[<id> setAutoresizingMask:NSViewNotSizable];
[<id> setTranslatesAutoresizingMaskIntoConstraints:YES];
更新:
如果将此方法用于计划设置为“隐藏”的NSView,则在调整框架的superview/窗口的大小时,自动布局系统仍将考虑隐藏NSView的框架。这意味着,如果在调整大小后,隐藏的NSView将位于superview的可见区域之外,则自动布局系统将阻止superview正确调整大小,而将强制superview框架包围隐藏的NSView
解决此问题的一个简单方法是在设置隐藏:是
并在设置隐藏:否
之前恢复宽度和高度后,将NSView的宽度和高度设置为零。例如,在代码中的某个点,使用NSViewself.按钮
:
...
[self.button setHidden:YES];
[self.button setFrameSize:NSZeroSize];
...
后来:
...
[self.button setFrameSize:NSMakeSize(160, 90)];
[self.button setHidden:NO];
...
但是,如果在NSView上设置了宽度/高度自动布局约束(以编程方式或通过Interface Builder),这些更改可能会引发如下警告:
Unable to simultaneously satisfy constraints:
(
"<NSLayoutConstraint:0x608000082990 H:[NSButton:0x6080001200a0(100)]>",
"<NSAutoresizingMaskLayoutConstraint:0x60800008bae0 h=--& v=--& H:[NSButton:0x6080001200a0(0)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x608000082990 H:[NSButton:0x6080001200a0(100)]>
当我们取消隐藏NSView时:
...
[self.button setTranslatesAutoresizingMaskIntoConstraints:NO];
[self.button setHidden:YES];
...
...
[self.button setTranslatesAutoresizingMaskIntoConstraints:YES];
[self.button setHidden:NO];
...
您还可以通过对NSView进行子类化并覆盖setHidden:
(注意!
)来自动执行此操作:
然后,您只需调用[self.button setHidden:YES]代码>或[self.button setHidden:否]
和重写的方法将处理所有问题。请在调用setFrame时使用错误的数据发布调用堆栈。可能您从错误的位置调用了帧更新。但你没有向我提供更多的信息。所以我帮不了你。改变画面意味着什么?是尺寸、位置吗-1@Avt我一直在试图以一种不受我正在处理这个问题的大项目束缚的方式来重现这种情况。我想所有来自更大程序的调用都是无益的,但正如我所说的,我很难找到问题的根源。我会在更简单的时候更新。你可能在视图上设置了自动布局约束,它们会自动布局视图。但是,是的,显示调用堆栈可以确认。在日志语句中包含[NSThread callStackSymbols]
。谢谢,但我认为这并不能解决我的问题,因为在我正在开发的更大的应用程序中,当从-awakeFromNib
以外的位置调用-setFrame:
时,甚至会发生反转。我已经用我的原始应用程序中的调用堆栈更新了我的问题。感谢您的调用被卡住。您的视图似乎已自动调整大小。您应该检查autoresizingMask和auto layout constraints。我已尝试将autoreziseMask设置为NSViewNotSizeable(这似乎没有效果)并删除所有约束(这将初始帧设置为与IB完全不同的内容,但仍然具有自动调整大小的功能。我还尝试将superview的-setAuotresizesSubviews:
设置为否,这也没有任何作用。您对如何阻止视图自动调整大小有何想法?autoresizingMask返回12,唯一的约束是
