uitextview尽头的额外空间-英雄云拓展知识分享

我添加了文字 UITextView 并了解我为我的界面的界限 UITextView 用青色。

Google.com以后，我想删除一些额外的空间。

- (void)viewDidLoad {
[super viewDidLoad];
NSString *desc = [self htmlAfterReplacingTagsAndAddingStyle];
_descriptionTextView.attributedText = [[NSAttributedString alloc] initWithData: [desc dataUsingEncoding:NSUTF8StringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
_descriptionTextView.linkTextAttributes = @{ NSForegroundColorAttributeName: [UIColor blueColor], NSUnderlineStyleAttributeName: [NSNumber numberWithInt:NSUnderlineStyleSingle] };
_descriptionTextView.dataDetectorTypes = UIDataDetectorTypeLink;
_descriptionTextView.scrollEnabled = NO;
[self setTextViewHeight];
}

setTextViewHeight

- (void)setTextViewHeight {
UIFont *font = [UIFont fontWithName:@"OpenSans" size:14.0];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, _descriptionContainer.frame.size.width, CGFLOAT_MAX)];
label.numberOfLines = 0;
label.lineBreakMode = NSLineBreakByWordWrapping;
label.font = font;
NSString *desc = [self htmlAfterReplacingTagsAndAddingStyle];
label.attributedText = [[NSAttributedString alloc] initWithData: [desc dataUsingEncoding:NSUTF8StringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
[label sizeToFit];
_descriptionTextView.backgroundColor = UIColor.cyanColor;
[_descriptionTextView setContentInset:UIEdgeInsetsMake(0, 0, ⑻0, 0)];
_descriptionContainerHeight.constant = label.frame.size.height;
}

我浏览了有关设置内容插图的信息，但这杯水车薪。更改⑻0的价值没有任何作用。

我很感谢一些唆使可以帮助我删除UitextView底部的额外空间。
