NSView 调整大小

发布于 2024-10-31 07:41:20 字数 197 浏览 4 评论 0原文

我有一个 NSView ，其中有一个 NSTextField 。问题是，每次显示视图之前， NSTextField 的大小都会改变，我希望 NSView 的大小也随之改变。因此，如果文本字段有 2 行长，则 nsview 会很小（只是勉强包围文本字段），但是当其长度为 10 行时，我不希望视图的大小切断文本字段，我希望视图随之增长。

我怎样才能做到这一点？谢谢。

这是我在表格视图中使用的，但它应该同样适用于您的情况：

    float textLabelWidth = 190;

    NSString *Text = [[deals objectAtIndex:[indexPath section]] objectForKey:@"title"];
    UIFont *cellFont = [UIFont fontWithName:@"Helvetica" size:13.0];
    CGSize constraintSize = CGSizeMake(textLabelWidth, MAXFLOAT);
    CGSize labelSize = [Text sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

    return labelSize.height + 20; // <--- this is what your NSView's height should be, just edit the textLabelWidth and padding (in this case 20) to whatever you desire.

希望有帮助！

This is what I use in my tableview, but it should apply equally to your situation:

    float textLabelWidth = 190;

    NSString *Text = [[deals objectAtIndex:[indexPath section]] objectForKey:@"title"];
    UIFont *cellFont = [UIFont fontWithName:@"Helvetica" size:13.0];
    CGSize constraintSize = CGSizeMake(textLabelWidth, MAXFLOAT);
    CGSize labelSize = [Text sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

    return labelSize.height + 20; // <--- this is what your NSView's height should be, just edit the textLabelWidth and padding (in this case 20) to whatever you desire.

Hope that helps!

您需要设置“contentHugging 和 contentCompression”优先级。

简而言之：

contentHugging: sets the preference where a control resists being made *larger* than it's intrinsic size

contentCompression: sets the preference where a control resists being made *smaller* than it's intrinsic size

苹果在这里有一个参考：

https:// developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/WorkingwithConstraintsinInterfaceBuidler.html

具体向下滚动到设置内容拥抱和压缩阻力优先级部分。

这就是处理文本字段等...剪切（即当文本字段具有“某些 testValue”变为“某些 testV ...”等时...

Your need to set the "contentHugging and contentCompression" priorities.

In short:

contentHugging: sets the preference where a control resists being made *larger* than it's intrinsic size

contentCompression: sets the preference where a control resists being made *smaller* than it's intrinsic size

Apple have a reference here:

https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/WorkingwithConstraintsinInterfaceBuidler.html

Specifically scroll down to the Setting Content-Hugging and Compression-Resistance Priorities section.

This is what deals with textFields etc... clipping (i.e. when a textfield has "some testValue" becomes "some testV..." etc...
