我試圖創建一個TableView中,把在從NSArray中的數據。不過,我收到此錯誤:的TableView - 信號SIGABRT
2012-12-21 15:53:10.239 Arr[13219:c07] -[UIView tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x71ccb60
2012-12-21 15:53:10.240 Arr[13219:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x71ccb60'

libc++abi.dylib: terminate called throwing an exception
我真的不知道什麼代碼是導致此,所以我就附上兩個表方法:NSArray中的
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
創建:
@implementation ArrViewController {
NSArray *tableData;
}
@synthesize itemTxt = _itemTxt;
@synthesize itemsLabel = _itemsLabel;
@synthesize model = _model;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
tableData = [NSArray arrayWithObjects:@"Egg Benedict", @"Mushroom Risotto", @"Full Breakfast", @"Hamburger", @"Ham and Egg Sandwich", @"Creme Brelee", @"White Chocolate Donut", @"Starbucks Coffee", @"Vegetable Curry", @"Instant Noodle with Egg", @"Noodle with BBQ Pork", @"Japanese Noodle with Pork", @"Green Tea", @"Thai Shrimp Cake", @"Angry Birds Cake", @"Ham and Cheese Panini", nil];
}
你有' - (NSInteger的)numberOfSectionsInTableView:(UITableView的*)的tableView'方法在你的代碼? –
不,我不這樣做,而是根據[AppCoda(http://www.appcoda.com/ios-programming-tutorial-create-a-simple-table-view-app/),它的工作原理沒有它 –
是如果它不是一個分組tableview你可能不需要它,否則'返回整數' –
