我希望每当调用 ViewWillAppear 方法时重新加载我的表视图的一部分，我已经实现了这样的：
- (void)viewWillAppear:(BOOL)animated {
NSIndexPath* rowToReload = [NSIndexPath indexPathForRow:0 inSection:1];
reloadRows = [NSArray arrayWithObjects:rowToReload, nil];
[self.tableView reloadRowsAtIndexPaths:reloadRows withRowAnimation:UITableViewRowAnimationNone];
}
下面是 rowforsection 方法，它指示哪些内容应该出现在每个 tableview 部分中：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(@"fadk");
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"PINGAS"];
[self.tableView setAlwaysBounceVertical:YES];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1
reuseIdentifier:@"PINGAS"] autorelease];
cell.accessoryType = UITableViewCellAccessoryNone;
// if ([indexPath section] == 0) {
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 3, 300, 41)];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 0, 300, 120)];
UIView *paddingView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 0)] autorelease];
paddingView.backgroundColor = [UIColor cyanColor];
// if ([indexPath row] == 0) {
if ([indexPath section] == 0) {
NSLog(@"0");
[cell addSubview:textField];
if ([indexPath row] == 0) {
textField.placeholder = @"Title";
}
else{
textField.placeholder = @"Location";
}
}
else if ([indexPath section] == 1) {
NSLog(@"1");
NSDateFormatter *formatter;
NSString *eSString1;
NSString *eEString2;
formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"h:mm a"];
cell.textLabel.text = @"Starts\nEnds";
cell.textLabel.numberOfLines = 2;
eSString1 = [formatter stringFromDate:eSTime];
eEString2 = [formatter stringFromDate:eEtime];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@\n%@", eSString1, eEString2];
cell.detailTextLabel.numberOfLines = 2;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
else{
NSLog(@"2");
[cell addSubview:textView];
}
textField.delegate = self;
textField.leftView = paddingView;
textField.leftViewMode = UITextFieldViewModeAlways;
textField.adjustsFontSizeToFitWidth = YES;
textField.textColor = [UIColor blackColor];
textField.keyboardType = UIKeyboardTypeAlphabet;
textField.returnKeyType = UIReturnKeyDone;
textField.backgroundColor = [UIColor clearColor];
textField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
textField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
textField.textAlignment = UITextAlignmentLeft;
textField.tag = 0;
//playerTextField.delegate = self;
textField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
[textField setEnabled: YES];
[textField release];
textView.delegate = self;
textView.textColor = [UIColor blackColor];
textView.keyboardType = UIKeyboardTypeAlphabet;
textView.returnKeyType = UIReturnKeyDone;
textView.backgroundColor = [UIColor clearColor];
textView.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
textView.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
textView.textAlignment = UITextAlignmentLeft;
textView.tag = 0;
[textView release];
// }
}
return cell;
}
这在第一次加载时运行良好，在第一次调用 viewWillAppear 之后，但之后该部分似乎从第一次加载和第二次加载中回收数据，虽然它仍然进入 cellforrow 部分，但它不再进入我在 viewWIllAppear 部分调用的部分。
