從UItableViewCell調用視圖

Question

我想讓我的第一個應用程序。我有6個文件：

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

裏面LeftPanelViewController.xib我有一個包含一個表視圖的視圖。我想從LeftPanelViewController.xib中的表視圖中設置一個單元格，當我按下該單元格時，我將能夠調用ForecastViewController.xib中的視圖。

我已在LeftPanelTableViewController.m

#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; 
}

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

} 


[tableView deselectRowAtIndexPath:indexPath animated:YES]; 
} 



@end 

Answer 1

而不是

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

使用下面的代碼

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

Answer 2

即使模態控制器的伎倆，也可能是不你想要什麼。什麼都沒有發生，因爲你的視圖控制器是零。可能您正在使用xCode中的「單視圖應用程序」模板，並且它沒有導航控制器。如果你想要一個，你應該像[[UINavigationController alloc] initWithRootViewController：]創建它，並將你的窗口根控制器設置爲新創建的navigationcontroller。
