我正在尝试在自定义联系人簿中实现搜索栏。我为搜索数据创建了NSDictionary，并在我的字典中添加了4个可变数组，包括 姓名，姓氏，电话类型，电话号码。
当我尝试在NSDictionary中搜索时，我的应用程序在单元格创建时崩溃了。当我只搜索一个数组（从字典valueforkey或直接从数组）时，它正在部分工作，但总是从列表中的第一个联系人获取另一个字符串（例如姓氏）。因为循环中不是所有参数，所以我必须按每个参数进行搜索，以便在我的联系人中获得正确的名字和姓氏。
这是我的代码：
#pragma mark SEARCH_BAR
-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[self.tableSearchBar resignFirstResponder];
}
-(void)searchBar:(UISearchBar *)serachBar textDidChange:(NSString *)searchText {
[filteredStrings removeAllObjects];
if (searchText.length == 0) {
isFiltered = NO;
} else {
isFiltered = YES;
//这里的目标是用4个可变数组创建NSDictionary
NSDictionary *filteredContacts = [NSDictionary dictionaryWithObjectsAndKeys:
contacts.firstNames, @"First Name",
contacts.lastNames, @"Last Name",
contacts.phoneTypes, @"Phone Type",
contacts.phoneNumbers, @"Phone Numbers",
nil];
//[filteredStrings addObject:filteredContacts];
for (NSString *str in filteredContacts) { // in this case for (NSString *str in [filteredContacts valueForKey:@"First Name"]) all working partially
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (stringRange.location != NSNotFound) {
filteredStrings = [[NSMutableArray alloc]init];
[filteredStrings addObject:str];
}
}
}
[self.contactsTableView reloadData];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (isFiltered) {
return [filteredStrings count];
}
return [contacts.firstNames count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = @"Cell";
abCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (!cell) {
cell = [tableView dequeueReusableCellWithIdentifier:cellID];
}
if (!isFiltered) {
cell.firstNameLabel.text = [contacts.firstNames objectAtIndex:indexPath.row];
cell.lastNameLabel.text = [contacts.lastNames objectAtIndex:indexPath.row];
cell.contactImage.image = [UIImage imageNamed:@"NOIMG.png"];
} else {
cell.firstNameLabel.text = [filteredStrings objectAtIndex:indexPath.row]; // Here my app is crashing when trying to search by all nsdictionary.
cell.lastNameLabel.text = [filteredStrings objectAtIndex:indexPath.row];
//cell.contactImage.image = [UIImage imageNamed:@"NOIMG.png"];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.contactsTableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"NextView"]) {
//if (!isFiltered) {
