到目前为止我为使搜索栏工作所做的工作......
- (void)viewDidLoad
{
[self makeData];
[super viewDidLoad];
self.mySearchBar.delegate = self;
self.myTableView.delegate = self;
self.myTableView.dataSource = self;
//Feedback button code here
UIBarButtonItem *feedback;
feedback = [[UIBarButtonItem alloc] initWithTitle:@"Contact" style:UIBarButtonItemStylePlain
target:self action:@selector(showEmail:)];
self.navigationItem.leftBarButtonItem = feedback;
[self.tableView reloadData];
self.tableView.scrollEnabled = YES;
}
-(void) makeData; {
list = [[NSMutableArray alloc] init];
[list addObject:[[NSMutableDictionary alloc]
initWithObjectsAndKeys:@"Acceleration", @"name" ,
@"acceleration.png", @"image" ,
@"Acceleration", @"description" ,nil]];
[list addObject:[[NSMutableDictionary alloc]
initWithObjectsAndKeys:@"Alternating Current", @"name" ,
@"alternating current.png", @"image" ,
@"Alternating Current", @"description" ,nil]];
[list addObject:[[NSMutableDictionary alloc]
initWithObjectsAndKeys:@"Ampere", @"name" ,
@"ampere.png", @"image" ,
@"Ampere", @"description" ,nil]];
[list addObject:[[NSMutableDictionary alloc]
initWithObjectsAndKeys:@"Amplitude", @"name" ,
@"amplitude.png", @"image" ,
@"Amplitude", @"description" ,nil]];
}
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
if (searchText.length == 0) {
isFiltered = FALSE;
}
else
{
isFiltered = TRUE;
filteredList = [[NSMutableArray alloc] init];
for (NSString *str in list) {
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (stringRange.location != NSNotFound) {
[filteredList addObject:str];
}
}
}
[self.myTableView reloadData];
}
-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
[self.myTableView reloadData];
}
然而,每次我尝试在应用程序中输入内容时都会崩溃,我会收到以下消息:
2013-05-29 11:36:09.734 PhysEX[4770:c07] -[__NSDictionaryM rangeOfString:options:]: unrecognized selector sent to instance 0x9468cd0
2013-05-29 11:36:09.735 PhysEX[4770:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSDictionaryM rangeOfString:options:]: unrecognized selector sent to instance 0x9468cd0'
如何让我的搜索工作?
