我正在使用该WEPopoverViewcontroller课程。首先，我导入这个类，然后我添加这个代码：
WEPopoverContentViewController.h
{
#import <UIKit/UIKit.h>
@interface WEPopoverContentViewController : UITableViewController {
NSArray *data;
}
@property(nonatomic,strong) NSArray *data;
@end
WEPopoverContentViewController.m
{
#import "WEPopoverContentViewController.h"
@implementation WEPopoverContentViewController
@synthesize data;
#pragma mark -
#pragma mark Initialization
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
self.contentSizeForViewInPopover = CGSizeMake(150, 3* 44 - 1);
data=[[NSArray alloc]initWithObjects:@"rahul",@"sharma" ,nil];
self.tableView.rowHeight = 44.0;
self.view.backgroundColor = [UIColor clearColor];
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
} #pragma mark - #pragma mark 表格视图数据源
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [viewcont.data count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
cell.textLabel.text = [NSString stringWithFormat:@"%@",[viewcont.data objectAtIndex:indexPath.row]];
cell.textLabel.textColor = [UIColor whiteColor];
return cell;
}
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"selected index here");
// Navigation logic may go here. Create and push another view controller.
}
这个视图控制器用于显示 popoverTable 我在这里使用我的视图控制器代码.....
ViewController.h
{
#import <UIKit/UIKit.h>
@class WEPopoverController;
@interface ViewController : UIViewController {
WEPopoverController *popoverController;
NSArray *data;
UITableView *table;
}
@property (nonatomic, strong) WEPopoverController *popoverController;
@property(nonatomic,strong) NSArray *data;
- (IBAction)onButtonClick:(UIButton *)button;
@end
}
}
我使用以下代码创建了一个按钮：
ViewController.m
{
- (IBAction)onButtonClick:(UIButton *)button {
if (self.popoverController)`
{
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController = nil;
[button setTitle:@"Show Popover" forState:UIControlStateNormal];
}
else
{
UIViewController *contentViewController = [[WEPopoverContentViewController alloc] initWithStyle:UITableViewStylePlain];
self.popoverController = [[WEPopoverController alloc] initWithContentViewController:contentViewController];
self.contentSizeForViewInPopover = CGSizeMake(200, 200);
data=[[NSArray alloc]initWithObjects:@"rahul",@"sharma", nil];
NSLog(@"data %@",data);
[self.popoverController presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
[button setTitle:@"Hide Popover" forState:UIControlStateNormal];
}
}
}
使用此代码，我点击了此按钮，然后控制器进入WEPopoverContentViewController 并根据此WEPopoverContentViewController (NSArray *data)创建行中的创建数组成功显示弹出窗口，但我希望我想在其中创建此数组ViewController.m，然后显示弹出窗口，但是当我们在其中创建数组时ViewController如何显示弹出表这个显示空白表？
