1. 使用此代码改变搜索栏“UITextField将backgroundImage

UITextField *searchField;NSUInteger numViews = [searchBar.subviews count];for(int i = 0; i < numViews; i++) { if([[searchBar.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?  searchField = [searchBar.subviews objectAtIndex:i]; }}if(!(searchField == nil)) { searchField.textColor = [UIColor whiteColor]; [searchField setBackground: [UIImage imageNamed:@"yourImage"]];//just add here gray image which you display in quetion [searchField setBorderStyle:UITextBorderStyleNone];}

该波纹管代码的变化UISearchBarIcon

 UIImageView *searchIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourSearchBarIconImage"]];searchIcon.frame = CGRectMake(10, 10, 24, 24);[searchBar addSubview:searchIcon];[searchIcon release];

也为改变searcBar图标搜索栏的你哪些可用的iOS 5 +

- (void)setImage:(UIImage *)iconImage forSearchBarIcon:(UISearchBarIcon)icon state:(UIControlState)state

在这里你可以设置4种UISearchBarIcon即UISearchBarIconBookmarkUISearchBarIconClearUISearchBarIconResultsListUISearchBarIconSearch我希望这可以帮助您...

2. 根据的UISearchBar 你这个函数适用于iOS 5.0 +。

- (void)setSearchFieldBackgroundImage:(UIImage *)backgroundImage forState:(UIControlState)state

用例：

[mySearchBar setSearchFieldBackgroundImage:myImage forState:UIControlStateNormal];

可悲的是，在iOS 4的你需要恢复到较少见其他的答案。

3. 只是自定义文本字段本身。我只是这样做的，它工作正常（的iOS 7）。

UITextField *txfSearchField = [_searchBar valueForKey:@"_searchField"];txfSearchField.backgroundColor = [UIColor redColor];

这样，您就不需要创建一个图像，它的大小，等..

4. 对于只改变颜色：

searchBar.tintColor = [UIColor redColor];

为应用背景图像：

[self.searchBar setSearchFieldBackgroundImage:       [UIImage imageNamed:@"Searchbox.png"]          forState:UIControlStateNormal];

5. 私有API的：

for (UIView* subview in [[self.searchBar.subviews lastObject] subviews]) { if ([subview isKindOfClass:[UITextField class]]) {  UITextField *textField = (UITextField*)subview;  [textField setBackgroundColor:[UIColor redColor]]; }}
