UISearchBar对于新手来说如果需要改变里面得内容图片需要查找大量的资料，现在整理出来，以供参考

1.创建

_mySearchBar = [[UISearchBaralloc] init];

//_mySearchBar.frame=CGRectMake(0, 0, SCREEN_WIDTH, 40);

_mySearchBar.delegate =self;

// //设置选项

//[_mySearchBar setScopeButtonTitles:[NSArray arrayWithObjects:@"First",@"Last",nil]];

[_mySearchBarsetAutocapitalizationType:UITextAutocapitalizationTypeNone];

[_mySearchBar sizeToFit];

_mySearchBar.backgroundColor =ZCColor(23,25, 28);

_mySearchBar.backgroundImage = [selfimageWithColor:[UIColorclearColor]size:_mySearchBar.bounds.size];

//可以改变取消按钮的颜色

_mySearchBar.tintColor=ZCColor(240,208, 122);

_mySearchBar.placeholder=@"请输入球场名称";

//改变输入字体的颜色

UITextField *searchField=[_mySearchBarvalueForKey:@"_searchField"];

searchField.textColor=ZCColor(240,208, 122);

//提示语的字体颜色

[searchField setValue:ZCColor(240,208, 122) forKeyPath:@"_placeholderLabel.textColor"];

[_mySearchBarsetSearchFieldBackgroundImage:[UIImageimageNamed:@"sousuokuang"]forState:UIControlStateNormal];

//修改提示语左边的图片

[_mySearchBarsetImage:[UIImageimageNamed:@"sousuo_icon"]forSearchBarIcon:UISearchBarIconSearchstate:UIControlStateNormal];

这里有个灰色的蒙版必须移除不然改变不了背景色

//移除灰色模板背景

for (UIView *subviewin [[_mySearchBar.subviewsfirstObject] subviews]) {

if ([subviewisKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {

[subviewremoveFromSuperview];

break;

}

//加入列表的header里面

self.tableView.tableHeaderView =_mySearchBar;

下面是创建搜索框自带的点击搜索时出现得tableview，搜索结果会出现在这个控制器上，具体代码方法和用法下篇介绍

_mySearchDisplayController = [[UISearchDisplayControlleralloc] initWithSearchBar:_mySearchBarcontentsController:self];

//_mySearchDisplayController = [[UISearchDisplayController alloc] init];

_mySearchDisplayController.delegate =self;

// searchResultsDataSource 就是 UITableViewDataSource

_mySearchDisplayController.searchResultsDataSource =self;

// searchResultsDelegate 就是 UITableViewDelegate

_mySearchDisplayController.searchResultsDelegate =self;

// [self.searchDisplayController setActive:NO animated:NO];

_mySearchDisplayController.searchResultsTableView.backgroundColor=[UIColorcolorWithPatternImage:[UIImageimageNamed:@"suoyou_bj_02"]];
