objective-c - 弄清楚 TwUI 中的自动调整大小掩码 - 底部边距？

Question

我在自动调整蒙版大小方面遇到了一些问题。这是交易:我正在使用最近发布的 TwUI ，它从 UIKit 中获取了很多，但它在 Mac 上。这就是我为 iOS 和 Mac 标记的原因。因此，我创建了一个底部需要有 40px 边距的 View ，无论垂直调整窗口的大小有多大。出于多种原因，我不允许水平扩展窗口。这是我正在谈论的示例。抱歉外观丑陋，我只是使用示例 View 进行测试。

对了，看到底部 40 像素的黑色空间了吗？

我正在通过执行以下操作来创建红色 View :

CGRect b = self.view.bounds;
b.origin.y += TAB_HEIGHT; //40px
b.size.height -= TAB_HEIGHT;

然后我用那个框架创建 View 。

但是，一旦我尝试在红色 View 上添加自动调整大小蒙版，它就会失去底部 40 像素，并填满整个 View 。对于那些不熟悉 TwUI 的人，自动调整掩码示例如下所示:

view.autoresizingMask = TUIViewAutoresizingFlexibleHeight;

因此，自动调整大小蒙版采用了 iOS 对应的蒙版。但是，设置该掩码会执行以下操作:

所以我的问题是，如何在此 View 的底部留出边距？

Answer 1

@Rob，自动调整大小没有问题。

下面的代码是我用TwUI github trunk修改了一个空项目

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application
    TUINSView *content = [[TUINSView alloc] initWithFrame:CGRectZero];
    CGRect b = [window frame];
    b.origin = CGPointZero;
    content.frame = b;

    [window setContentView:content];
    TUIView *viewA = [[TUIView alloc] initWithFrame:CGRectZero];
    viewA.frame = content.bounds;
    viewA.backgroundColor = [TUIColor blackColor];
    [content setRootView:viewA];
    viewA.autoresizingMask = TUIViewAutoresizingFlexibleSize;
    TUIView *viewB = [[TUIView alloc] initWithFrame:CGRectZero];
    viewB.backgroundColor = [TUIColor redColor];
    b = viewA.bounds;
    b.origin.y+=30;
    b.size.height-=30;
    viewB.frame = b;
    [viewA addSubview:viewB];
    viewB.autoresizingMask = TUIViewAutoresizingFlexibleSize;
}

编辑:我对我的 TUIViewController 的 loadView 进行了编码，到目前为止效果很好。

- loadView {
    TUIView *v = [[TUIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
    tableView = [[TUITableView alloc] initWithFrame:v.bounds style:TUITableViewStylePlain];
    [tableView scrollToTopAnimated:NO];
    tableView.autoresizingMask = TUIViewAutoresizingFlexibleSize;
    document = [[BBSDocDocument alloc] init];
    tableView.delegate = self;
    tableView.dataSource = self;
    CGRect rect = [v bounds];
    [v addSubview:tableView];
    [self setView:v];
}

编辑 2:我的带有 TUIViewController 子类的代码:

//TestVC.h:

#import <Foundation/Foundation.h>
#import "TUIKit.h"

@interface TestVC : TUIViewController {
@private
    TUIView *viewA;
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil;
@end


//TestVC.m
@implementation TestVC

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nil bundle:nil];
    if (self) {
        // Initialization code here.
    }

    return self;
}

- (void)loadView {
    self.view = [[[TUIView alloc] initWithFrame:CGRectZero] autorelease];
    self.view.autoresizingMask = TUIViewAutoresizingFlexibleSize;
}


//application delegate:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application
    TUINSView *content = [[TUINSView alloc] initWithFrame:CGRectZero];
    CGRect b = [window frame];
    b.origin = CGPointZero;
    content.frame = b;

    [window setContentView:content];
    TUIView *viewA = [[TUIView alloc] initWithFrame:CGRectZero];
    viewA.frame = content.bounds;
    viewA.backgroundColor = [TUIColor blackColor];
    [content setRootView:viewA];
    [viewA setAutoresizingMask:TUIViewAutoresizingFlexibleSize];
    TUIView *viewB = [[TUIView alloc] initWithFrame:CGRectZero];
    viewB.backgroundColor = [TUIColor redColor];
    b = viewA.bounds;
    b.origin.y+=30;
    b.size.height-=30;
    viewB.frame = b;
    [viewA addSubview:viewB];
    viewB.autoresizingMask = TUIViewAutoresizingFlexibleSize;
    TestVC *testVC = [[TestVC alloc] initWithNibName:nil bundle:nil];
    testVC.view.frame = viewB.bounds;
    testVC.view.backgroundColor = [TUIColor yellowColor];
    [viewB addSubview:testVC.view];
}
