当我在我的表视图中进行搜索的数据我收到此崩溃。我使用的文本框为搜索栏。这里是我的代码:
NSMutableArray *searchArray;
NSString *searchTextString;
BOOL isFilter;
@property NSMutableArray *TableDataArray;
- (void)viewDidLoad {
[super viewDidLoad];
[self.searchTextField addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
[self updateSearchArray];
[self.tableView reloadData];
}
- (NSInteger)tableView:(nonnull UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [searchArray count];
}
- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"SubNotificationCell";
SubNotificationCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSDictionary *dict;
if(isFilter) {
dict = [[self->searchArray objectAtIndex:indexPath.row] objectForKey:@"Eqktx"];
} else {
dict = [self.EtNotifRepTableDataArray objectAtIndex:indexPath.row];
}
NSString* notifValue = [dict objectForKey:@"Qmnum"];
NSString* equipNameValue = [dict objectForKey:@"Eqktx"];
NSString *values = @":";
cell.notifValueLabel.text = [NSString stringWithFormat: @"%@ %@", values, notifValue];
cell.equipNameValueLabel.text = [NSString stringWithFormat: @"%@ %@", values, equipNameValue];
return cell;
}
-(void)textFieldDidChange:(UITextField*)textField {
searchTextString = textField.text;
[self updateSearchArray];
}
-(void)updateSearchArray {
if (searchTextString.length != 0) {
isFilter=YES;
searchArray = [NSMutableArray array];
for ( NSDictionary* item in _EtNotifRepTableDataArray ) {
if ([[[item objectForKey:@"Eqktx"] lowercaseString] rangeOfString:[searchTextString lowercaseString]].location != NSNotFound) {
[searchArray addObject:item];
}
}
} else {
isFilter=NO;
searchArray = _EtNotifRepTableDataArray;
}
[self.tableView reloadData];
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
我需要寻找一个号码以及一个字符串。但它与崩溃,出现如下错误:
***终止应用程序由于未捕获的异常 'NSInvalidArgumentException',原因: ' - [__ NSCFString objectForKey:]:无法识别的选择发送到实例0x280e083f0'
在我viewdidload
@property NSMutableArray *EtNotifRepTableDataArray;
_EtNotifRepTableDataArray = [[NSMutableArray alloc]init];
for (NSDictionary *dict in arr) {
[dict description];
NSString *Qmart = [dict objectForKey:@"Qmart"];
NSString *Phase = [dict objectForKey:@"Phase"];
if ([Qmart isEqualToString:_qmartValue] && [Phase isEqualToString:_phaseValue]){
[self.EtNotifRepTableDataArray addObject:dict];
}
}
更换了与此您cellForRowAtIndexPath
方法。
- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"SubNotificationCell";
SubNotificationCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSDictionary *dict;
if(isFilter) {
// HERE was the problem.
//dict = [[self->searchArray objectAtIndex:indexPath.row] objectForKey:@"Eqktx"];
dict = [self.searchArray objectAtIndex:indexPath.row]
} else {
dict = [self.EtNotifRepTableDataArray objectAtIndex:indexPath.row];
}
NSString* notifValue = [dict objectForKey:@"Qmnum"];
NSString* equipNameValue = [dict objectForKey:@"Eqktx"];
NSString *values = @":";
cell.notifValueLabel.text = [NSString stringWithFormat: @"%@ %@", values, notifValue];
cell.equipNameValueLabel.text = [NSString stringWithFormat: @"%@ %@", values, equipNameValue];
return cell;
}
问题是,你是直接获取的对象cellForRowAtIndexPath
方法,它的过滤器部分回你一个NSString的值,然后再在你想从中得到的NSString导致崩溃objectForKey
,因为的NSString没有已知的方法objectForKey
编辑:
它不涉及到崩溃,但你也应该更新基于过滤此方法。
- (NSInteger)tableView:(nonnull UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(isFilter) {
return [searchArray count];
} else {
return [self.EtNotifRepTableDataArray count];
}
}
尝试和分享您的结果。
