自定义UISearchBar UI

之前在自定义UISearchBar的时候碰到了钉子.(Xcode7.2/iOS 7.1)

自定义UISearchBar的时候有遇到不熟悉的属性,想要达到想要的的自定义效果.只能像往常一样求助网络.结果各种各样的都有,许多还是不起作用的,准确的说是和我的要求不匹配,当然很多是我没有弄懂造成的.(这里吐槽一下,经常因为网络不好使直接百度,结果证明还是stackoverflow靠谱.)

方法都针对iOS 7以后.

• 1.0 输入字体颜色和placeholder颜色 

  UITextField *searchField = [_searchBar valueForKey:@"_searchField"];
  searchField.textColor = TEXTCOLOR;
  [searchField setValue:PLACEHOLDERCOLOR forKeyPath:@"_placeholderLabel.textColor"];

• 2.0 左边搜索图标Offset/Image/Size 
  在这里我直接create一个view然后赋给leftView并不起作用,望指点. 

  searchField.leftView.frame = CGRectMake(0, 0, 18, 18);
  [_searchBar setImage:[UIImage imageNamed:@"searchIcon"] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
  //[_searchBar setPositionAdjustment:UIOffsetMake(200, 0) forSearchBarIcon:UISearchBarIconSearch];

• 3.0 textField Offset 

  [_searchBar setSearchTextPositionAdjustment:UIOffsetMake(8, 0)];

• 4.0 搜索条背景颜色&搜索输入框背景色 

  _searchBar.barTintColor = TINTCOLOR; 
    searchTextField = [[[_searchBar.subviews firstObject] subviews] lastObject];
    searchTextField.backgroundColor = TINTCOLOR;

• 5.0 闪烁光标颜色 

  _searchBar.tintColor = [UIColor colorWithRed:55/255.0 green:200/255.0 blue:237/255.0 alpha:1.0];

• 6.0 搜索文本框背景图片&搜索框背景图片 

  [_searchBar setSearchFieldBackgroundImage:[UIImage imageNamed:@"top"] forState:UIControlStateNormal];
  [_searchBar setBackgroundImage:[UIImage imageNamed:@"top"]];
