我有一个带有自定义单元格的表格 View ，自定义单元格上有 uibuttons，如果我选择按钮，除了单元格剩余的所有单元格都应该变灰或禁用是可能的。
//tableview 类中的代码
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
NSLog(@"No OF rows:%d",[contents count]);
return [contents count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
static NSString *cellIdentifier = @"cell";
// Try to retrieve from the table view a now-unused cell with the given identifier.
cell = (uploadCustomCell *)[tableView dequeueReusableCellWithIdentifier:@"uploadCustomCell"];
if (cell == nil) {
NSLog(@"cell allocated");
// Use the default cell style.
cell = [[uploadCustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"uploadCustomCell"];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"uploadCustomCell"
owner:self options:nil];
cell = [nib objectAtIndex:0];
}
saveBtnCcell.hidden = YES;
cell.textNamefield.hidden = YES;
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell.defaultSwitch setEnabled:NO];
dictionaryContents = [contents objectAtIndex:indexPath.row];
NSLog(@"dict dict :%@",dictionaryContents);
//
cell
.nameLabelCell.text = [dictionaryContents valueForKey:@"VideoName"];
cell.userName.text = [dictionaryContents valueForKey:@"User"];
NSLog(@"Array Image:%@",arrayimage);
cell.thumbImg.image = [arrayimage objectAtIndex:indexPath.row];
NSLog(@"ARimage:%@,index%d",[arrayimage objectAtIndex:indexPath.row],indexPath.row);
NSString *defaultVideo = [dictionaryContents valueForKey:@"DefaultVideo"];
NSLog(@"Default Video:%@",defaultVideo);
if ([defaultVideo isEqual: @"1"]) {
// [cell.defaultSwitch setOn:YES animated:YES];
[defaultSwitche setOn:YES animated:YES];
}
else{
// [cell.defaultSwitch setOn:NO animated:YES];
[defaultSwitche setOn:NO animated:YES];
}
[cell.defaultSwitch addTarget:self action:@selector(setState:) forControlEvents:UIControlEventValueChanged];
VideoNameTextField.hidden = YES;
return cell;
}
//自定义单元格中的代码
@interface uploadCustomCell (){
UploadAllViewController *uploadAll;
}
@end
@implementation uploadCustomCell
@synthesize textNamefield;
@synthesize savebtn,edit,nameLabelCell,textLabel,uploadBTN;
@synthesize defaultSwitch;
//@synthesize uploadAll;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (void)dealloc {
[_userName release];
[_thumbImg release];
//[savebtn release];
[textNamefield release];
[nameLabelCell release];
[_test release];
[savebtn release];
[defaultSwitch release];
[uploadBTN release];
[super dealloc];
}
- (IBAction)editAction:(id)sender {
[uploadBTN setEnabled:NO];
uploadAll = [[UploadAllViewController alloc]init];
CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:uploadAll.tabelView1];
NSIndexPath *indexPath = [uploadAll.tabelView1 indexPathForRowAtPoint:buttonPosition];
int no = indexPath.row;
NSLog(@"index path :%d",no);
[uploadAll didEditButtonPressed:self];
}
- (IBAction)saveBtnAction:(id)sender {
[uploadBTN setEnabled:YES];
[uploadAll didSaveButtonPressed:self];
}
当我选择这个editAction时:除了单元格剩余的单元格应该是灰色的。
最佳答案
在您的 cellForRowAtIndexPath您必须考虑表格 View 的状态，即是否选择了一个或零个单元格。使用它来根据需要更改单元格的外观。在下面的例子中，我假设你有一个没有任何部分的直线数组，但是同样的原理也适用于 indexPath。 s 也是。我使用 int selectedRow设置为 -1如果没有选择单元格。
#define kNoCellSelected -1
// in cellForRowAtIndexPath:
if (self.selectedRow == kNoCellSelected) {
cell.backgroundView.backgroundColor = normalColor;
cell.userInteractionEnabled = YES;
}
else if (self.selectedRow != indexPath.row) {
cell.backgroundView.backgroundColor = disabledColor;
cell.userInteractionEnabled = NO;
}
不要忘记设置
selectedRow在 didSelectRowAtIndexPath:在 viewDidLoad .
