如何設置UITableView tableHeaderView的寬度將比UITableView寬度更寬？

Question

我viewDidLoad方法是這樣創造UITableView：

_tableView = [[UITableView alloc] initWithFrame:CGRectMake(25.0, 0.0, 277.0, 393.0) style:UITableViewStyleGrouped]; 
mySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)]; 
[self.tableViewLists setTableHeaderView:mySearchBar]; 
CGRect newFrame = mySearchBar.frame; 
newFrame.size.width = newFrame.size.width + 50.0f; 
newFrame.origin.x = newFrame.origin.x - 25.0f; 
mySearchBar.frame = newFrame; 
[self.tableViewLists setTableHeaderView:mySearchBar]; 

我要添加UISearchBar爲UITableViewtableHeaderView，將有這樣的框架：我把我的UISearchBar後UITableView tableHeaderView

CGRectMake(0.0f, 0.0f, 320.0f, 44.0f) 

，這是框架拉伸爲UITableView的寬度。我可以以某種方式更改UISearchBar的框架？

Answer 1

把UISearchBar放在UITableView內沒有什麼意義，寬度小於實際的UISearchBar。我認爲這將是默認的行爲來拉伸它（在這種情況下縮小它）。你可以看看這個question/answe r得到一些想法（主要是因爲打印屏幕和一些答案）。我會建議，將是UITableView以上UISearchBar，這就是它......

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
return 10; 
} 

// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier: 
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls) 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
static NSString *cellidentifier=@"cellidentifier"; 

UITableViewCell *Cell=[tableView dequeueReusableCellWithIdentifier:cellidentifier]; 
if (Cell==nil) { 
    Cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentifier]; 
} 

Cell.textLabel.text=@"hello"; 
return Cell; 
} 

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
