Question

我正在搜索将UILabel添加到搜索字段前面的UISearchBar的方法。

我试图像这样添加一个UILabel：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
  self.searchDisplayController.searchBar.showsCancelButton = YES;

  UILabel *searchResultCount = [[UILabel alloc] initWithFrame:CGRectMake(8, 8, 50, 28)];
  searchResultCount.text = @"357"; //Itemscount of Searchresult

  [self.searchDisplayController.searchBar addSubview:searchResultCount];
}

结果看起来像==＆gt; http://i.stack.imgur.com/x3sel.png

我怎样才能完成这项工作？它应该是

[356] [搜索字段] [取消]

感谢您的任何建议

Answer 1

您可以调整搜索文本位置。只需添加：

self.searchDisplayController.searchBar.searchTextPositionAdjustment = UIOffsetMake(65., 0.);

Answer 2

我确实解决了它。子类UISearchBar并在layoutSubviews中进行更改。

这是我的代码。

#import "CustomSearchBar.h"

@implementation CustomSearchBar

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

-(void)layoutSubviews
{
  [super layoutSubviews];

  float cancelButtonWidth = 84.0;
  UITextField *searchField;
  UILabel *resultLabel;

  UIView *topView = [self.subviews lastObject];
  for (UIView *subView in topView.subviews)
  {
    if ([subView isKindOfClass:NSClassFromString(@"UITextField")])
    {
      searchField = (UITextField *)subView;
    }
    else if ([subView isKindOfClass:NSClassFromString(@"UILabel")])
    {
      resultLabel = (UILabel*)subView;
    }
  }

  if(!searchField) {return; }

  if (self.showsCancelButton)
  {
    if(!resultLabel)
    {
      resultLabel = [[UILabel alloc] initWithFrame:CGRectMake(8, 8, 40, 28)];
      resultLabel.text = @"356";
      [topView addSubview:resultLabel];
    }
    [searchField setFrame:CGRectMake(60, 8, self.frame.size.width - 100 - cancelButtonWidth, 28)];

  }
  else
  {
    [searchField setFrame:CGRectMake(8, 8, 484, 28)];
    if(resultLabel)
    {
      [resultLabel removeFromSuperview];
    }
  }
}
@end
