Question

我编写了一个代码，用于将文本包含在视图中

-(void)buildFrames
{
    NSTextStorage *textstorege=[[NSTextStorage alloc]initWithAttributedString:self.bookMarkup];
    _layoutManager =[[NSLayoutManager alloc]init];
    [textstorege addLayoutManager:_layoutManager];
    NSTextContainer *textcontainer=[[NSTextContainer alloc]initWithSize:CGSizeMake(self.bounds.size.width, FLT_MAX)];
    [_layoutManager addTextContainer:textcontainer];
    UITextView *textView = [[UITextView alloc]initWithFrame:self.bounds textContainer:textcontainer];
    textView.scrollEnabled = YES;
    [self addSubview:textView];
}

然后错误就像财产＆＃34; Bounds＆＃34;在对象类型视图控制器中找不到...

你的专栏：

UITextView *textView = [[UITextView alloc]initWithFrame:self.bounds textContainer:textcontainer];

如果self是UIViewController或UISplitViewController，那么self没有界限，它就是控制器。您想要控制器负责的视图的界限。

尝试self.view.bounds，这样你的行就会变成：

UITextView *textView = [[UITextView alloc]initWithFrame:self.view.bounds textContainer:textcontainer];

在类型视图控制器中找不到属性“bounds”
