Question

我正在尝试制作我的第一款应用。我有6个文件：

LeftPanelViewController.h LeftPanelViewController.m LeftPanelViewController.xib ForecastViewController.h ForecastViewController.m ForecastViewController.xib

在LeftPanelViewController.xib中，我有一个包含表视图的视图。我想从我在LeftPanelViewController.xib中的表视图中设置一个单元格，所以当我按下那个单元格时，我将能够调用我在ForecastViewController.xib中的视图。

在我的LeftPanelTableViewController.m

代码下面

#import "LeftPanelViewController.h"
#import "ForecastViewController.h"


@interface LeftPanelViewController ()

@property (nonatomic, weak) IBOutlet UITableView *myTableView;
@property (nonatomic, weak) IBOutlet UITableViewCell *cellMain;
@property (copy, nonatomic) NSArray *MRP;

@end

@implementation LeftPanelViewController

- (void)viewDidLoad
{
[super viewDidLoad];

Array = [[ NSMutableArray alloc] init];
[Array addObject:@"Forecast"];
[Array addObject:@"Inventory"];

}

- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [Array count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
SimpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:SimpleTableIdentifier];

//add an image to the tablecell
UIImage *image = [UIImage imageNamed:@"Icon.png"];
cell.imageView.image = image;

}
cell.textLabel.text = [Array objectAtIndex:indexPath.row];

if (indexPath.row < 7) {
cell.detailTextLabel.text = @"Account";
} else {
cell.detailTextLabel.text = @"Settings";
}
return cell;
}

[super viewDidUnload];

}


[tableView deselectRowAtIndexPath:indexPath animated:YES];
}



@end

Answer 1

而不是

[self.navigationController pushViewController:Forecast animated:YES];

使用

[self presentViewController:Forecast animated:YES completion:nil];

Answer 2

即使模态控制器完成了这个技巧，也可能不是你想要的。什么都没发生，因为你的视图控制器是零。可能你正在使用xCode的“单一视图应用程序”模板，它没有导航控制器。如果你想要一个，你应该创建它[[UINavigationController alloc] initWithRootViewController：]并将你的窗口根控制器设置为新创建的navigationcontroller。

从UItableViewCell调用视图
