- 当我接触到搜索栏,键盘显示出来,该TableView中有一个黑色的封面上,并我可以开始输入

- 这工作一切伟大的。当我点击清除(x)按钮,它只是返回到第一个屏幕截图状态(空搜索栏,结果上方的黑框)
但是,它来了!
- 当我输入一些东西,然后移动搜索结果,键盘隐藏(标准UISearchDisplayController事) 像这样:

当我然后一下就清楚(x)按钮,该程序崩溃与SIGABRT错误:

..我不知道如何解决这一问题:(
这里是我的源代码:(不知道你需要解决的问题是什么) http://joeranbosma.nl/xcode/wearch_stack.zip
但我认为这是最有用的部分:
- (void)viewDidLoad {
[super viewDidLoad];
//Initialize the array.
listOfItems = [[NSMutableArray alloc] init];
copyListOfItems = [[NSMutableArray alloc] init];
staticlist = [[NSMutableArray alloc] init];
staticlist = listOfItems;
//Add items
[listOfItems addObject:@"Iceland"];
[listOfItems addObject:@"Greenland"];
[listOfItems addObject:@"Switzerland"];
[listOfItems addObject:@"Norway"];
[listOfItems addObject:@"New Zealand"];
[listOfItems addObject:@"Greece"];
[listOfItems addObject:@"Rome"];
[listOfItems addObject:@"Ireland"];
//Set the title
self.navigationItem.title = @"Wearch";
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (searching)
return [copyListOfItems count];
else {
return [listOfItems count];
}
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
if(searching)
cell.textLabel.text = [copyListOfItems objectAtIndex:indexPath.row];
else {
NSString *txtLbl = [listOfItems objectAtIndex:indexPath.row];
cell.textLabel.text = [txtLbl stringByAppendingString:@"x"];
}
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Get the selected word
NSString *selectedWord = nil;
if(searching)
selectedWord = [copyListOfItems objectAtIndex:indexPath.row];
else {
selectedWord = [listOfItems objectAtIndex:indexPath.row];
}
//Initialize the detail view controller and display it.
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];
dvController.selectedWord = selectedWord;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
dvController = nil;
}
- (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar {
searching = YES;
}
- (void)searchBar:(UISearchBar *)theSearchBar textDidChange:(NSString *)searchText {
//Remove all objects first.
[copyListOfItems removeAllObjects];
if([searchText length] > 0) {
searching = YES;
[self searchTableView];
}
else {
searching = NO;
}
[self.tableView reloadData];
}
- (void) searchBarSearchButtonClicked:(UISearchBar *)theSearchBar {
[self searchTableView];
}
- (void) searchTableView {
NSString *searchText = searchBar.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
NSMutableArray *results1 = [[NSMutableArray alloc] init];
NSMutableArray *results2 = [[NSMutableArray alloc] init];
[searchArray addObjectsFromArray:listOfItems];
for (NSString *sTemp in searchArray) {
NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (titleResultsRange.length > 0){
if (titleResultsRange.location == 0) {
[results1 addObject:sTemp];
}
else{
[results2 addObject:sTemp];
}
}
}
for (NSString *sTemp in results1) {
[copyListOfItems addObject:sTemp];
}
for (NSString *sTemp in results2) {
[copyListOfItems addObject:sTemp];
}
[searchArray release];
searchArray = nil;
}
我希望你们其中一个能解决这个问题。
你也可以说如果你喜欢的图片?
哇,非常感谢! 确实是这个问题。 但是,除了您发现问题之外,我现在更了解该语言。 我从来没有看过的控制台,因为当时很多这样的: '422af1 0x14d3ec9 0x36e5c2 0x36e55a 0x413b76 0x41403f 0x4132fe 0x393a30 0x393c56 0x37a384 0x36daa9 0x1bc8fa9 0x14a61c5 0x140b022 0x140990a 0x1408db4 0x1408ccb 0x1bc7879 0x1bc793e 0x36ba9b 0x256d 0x24e5)' 我只是没”我知道那里有些有用的东西,所以我没有看得更远。 所以:非常感谢! – Joeran 2012-03-26 06:17:02
很高兴为您提供帮助,特别是想要了解更多信息的人。因此,我添加了一些技巧来帮助您提到的无用的十六进制堆栈跟踪。 – NJones 2012-03-27 15:14:06
谢谢你,我现在要添加一个异常处理程序:) – Joeran 2012-03-27 17:59:43
