[英]How to pass data of the second table view cell when i click the first table view cell
[英]iOS: How to pass first view controller label data of table view cell to textView of second view controller?
我正在开发一个应用程序,在其中单击按钮时,我想向第二个视图控制器的textView显示第一个视图控制器的表格视图单元格标签数据。 我已经实现了代码,但是当我单击按钮时,第二个视图的textView变为空白。 请建议我在下面的代码中我在哪里做错了,我尝试了很多次但未能成功。
第一视图控制器:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.jobPostedTableView.dataSource = self;
//Slide Navigation
[self.sideNavigation addTarget:[SlideNavigationController sharedInstance] action:@selector(toggleLeftMenu) forControlEvents:UIControlEventTouchUpInside];
WebManager *manager = [WebManager sharedInstance];
[manager getJobPostedWithCompletionBlock:^(id response){
NSDictionary *dictionary = (NSDictionary *)response;
// Read data from JSON
NSDictionary *responseObject = [dictionary objectForKey:@"response"];
NSLog(@"The Array%@",responseObject);
self.bids = [responseObject objectForKey:@"bids"];
self.job_description = [responseObject objectForKey:@"job_description"];
self.job_id = [responseObject objectForKey:@"job_id"];
self.job_completed = [responseObject objectForKey:@"job_completed"];
self.job_latitude = [responseObject objectForKey:@"job_latitude"];
self.job_longitude = [responseObject objectForKey:@"job_longitude"];
self.job_priority = [responseObject objectForKey:@"job_priority"];
self.job_start_date = [responseObject objectForKey:@"job_start_date"];
self.job_title = [responseObject objectForKey:@"job_title"];
[self.jobPostedTableView reloadData];
}];
self.reversedGeocodes = [NSMutableDictionary dictionary];
}
#pragma mark - TableView Data Source
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.job_title count];
}
- (NSInteger) numberOfSectionsInTableview:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"JobTableViewCell";
JobTableViewCell *cell = (JobTableViewCell *)[self.jobPostedTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil) {
cell = [[JobTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
// Comparing array string to display an urgent image
if ([[self.job_priority objectAtIndex:indexPath.row]
isEqualToString:@"urgent"]) {
cell.urgentLabel.hidden = NO;
} else {
cell.urgentLabel.hidden = YES;
}
// Condition whether job completed is open or closed
if ([[self.job_completed objectAtIndex:indexPath.row]
isEqualToString:@"1"]) {
cell.jobStatus.text = @"Open";
[cell.jobStatus setTextColor:[UIColor colorWithRed:(84/255.f) green:(56/255.f) blue:(255/255.f) alpha:1.0f]];
cell.flagImage.image = [UIImage imageNamed:@"jobPosted_opened.PNG"];
} else {
cell.jobStatus.text = @"Closed";
[cell.jobStatus setTextColor:[UIColor colorWithRed:(179/255.f) green:(179/255.f) blue:(180/255.f) alpha:1.0f]];
cell.flagImage.image = [UIImage imageNamed:@"jobPosted_closed.PNG"];
}
cell.jobTitle.text = [self.job_title objectAtIndex:indexPath.row];
cell.jobContent.text = [self.job_description objectAtIndex:indexPath.row];
cell.bidsLabel.text = [[self.bids objectAtIndex:indexPath.row ]stringValue];
// Latitude and Longitude
float lat = [self.job_latitude[indexPath.row] floatValue];
float lng = [self.job_longitude[indexPath.row] floatValue];
[self locationNameWithLat:lat
lng:lng
completionHandler:^(NSString *locationName, NSError *error) {
cell.locationJob.text = locationName;
}];
return cell;
}
- (IBAction)onClickJobButton:(id)sender {
JobDetailsViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"JobDetailsViewController"];
[self.navigationController pushViewController:vc animated:YES];
NSIndexPath *indexPath = [self.jobPostedTableView indexPathForSelectedRow];
JobDetailsViewController *jobDetailsController = [[JobDetailsViewController alloc]init];
jobDetailsController.jobDetailView = [self.job_description objectAtIndex:indexPath.row];
}
第二视图控制器:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
WebManager *manager = [WebManager sharedInstance];
NSString *user_name = manager.completeName;
self.nameLabel.text = user_name;
self.jobtextView.text = self.jobDetailView;
}
如果使用的是segues,则可以使用prepareForSegue方法发送文本:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
{
// Get reference to the destination view controller
YourSecondViewController *vc = [segue destinationViewController];
// Pass labelData which is a string
[vc setTextString:labelData];
}
}
并且不要忘记在SecondViewController.h
声明字符串属性
@property(nonatomic,strong) NSString *textString;
