我已经成功设置了UITableView
从数组中提取其单元格标签的 a。我想要做的是将一个对象添加到该数组并重新加载 UITableView以便它显示该新对象并创建一个新单元格。不幸的是,我没有运气。
我知道这可能是我在代码中所做的非常愚蠢的事情,但是有人可以让我知道我哪里出错了吗?这是我目前正在使用的:
这是我的整个.h:
@interface crastinatrViewController : UIViewController <UITableViewDataSource, UITableViewDelegate> {
NSMutableArray *tasksList;
UIView *addtaskview;
}
@property (strong, nonatomic) IBOutlet UITableView *mainTableView;
@property (nonatomic, retain) NSMutableArray *tasksList;
@property (strong, nonatomic) IBOutlet UITextField *taskName;
- (IBAction)addTask:(id)sender;
- (IBAction)startaddTask:(id)sender;
@end
和我的整个.m:
@interface crastinatrViewController ()
@end
@implementation crastinatrViewController
@synthesize mainTableView;
@synthesize tasksList;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
tasksList = [[NSMutableArray alloc] initWithObjects:nil];
self.mainTableView.delegate = self;
self.mainTableView.dataSource = self;
[self.taskName becomeFirstResponder];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSInteger rows = [[self tasksList] count];
NSLog(@"rows is: %d", rows);
return rows;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *contentForThisRow = [[self tasksList] objectAtIndex:[indexPath row]];
static NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
// Do anything that should be the same on EACH cell here. Fonts, colors, etc.
}
// Do anything that COULD be different on each cell here. Text, images, etc.
[[cell textLabel] setText:contentForThisRow];
return cell;}
-(IBAction)startaddTask:(id)sender {
addtaskview = [self.storyboard instantiateViewControllerWithIdentifier:@"addTaskView"];
[self presentViewController:addtaskview animated:YES completion:nil];
}
- (IBAction)addTask:(id)sender {
[tasksList addObject:self.taskName.text];
[self dismissViewControllerAnimated:YES completion:nil];
[mainTableView reloadData];
}
@end
