我的TableView应用程序有一个自定义单元格。 TableViewController被称为“BlogView”。我的自定义单元格上有几个按钮,一个是共享按钮。我想在按下其中一个按钮时显示UIActivityViewController。
在我的自定义单元格的标题中,我有一个属性:
@property (nonatomic, retain) BlogView *myViewController;
在自定义单元格中,我有layoutSubview:
self.commentButton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.commentButton addTarget:self action:@selector(didTapCommentButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.commentButton setTitle:@"Share" forState:UIControlStateNormal];
[self.commentButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.commentButton setTitleColor:[UIColor greenColor] forState:UIControlStateHighlighted];
对于选择器didTapCommentButtonAction我有:
- (void)didTapCommentButtonAction:(id)sender
{
NSLog(@"CommentButtonTAPPED");
Mail *mail = [[Mail alloc]init];
NSString *html = self.prayerObject[@"Request"];
NSString *thetitle = [self.prayerObject[@"Title"] stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
NSString *thedate = self.prayerObject[@"dateMade"];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"MMM_dd_yyyy"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"GMT"]];
NSDate *theNewDate1 = [dateFormat dateFromString:thedate];
NSString *theNewDate = [dateFormat stringFromDate:theNewDate1];
mail.thehtml = html;
self.nameofhtmlfile = [[[[@"http://www.iprayed4u.net/app/" stringByAppendingString:thetitle] stringByAppendingString:@"_"] stringByAppendingString:theNewDate] stringByAppendingString:@".html"];
// Reminder *thereminder = [[Reminder alloc] init];
//thereminder.thehtml = html;
//thereminder.thetitle = thetitle;
//thereminder.thedate = thedate;
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[self] applicationActivities:@[mail]];
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
activityVC.excludedActivityTypes = @[ UIActivityTypePostToWeibo,
UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact,
UIActivityTypeMail,
UIActivityTypePrint
];
}
else {
activityVC.excludedActivityTypes = @[ UIActivityTypePostToWeibo,
UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact,
UIActivityTypeMail,
UIActivityTypePrint,
UIActivityTypeAirDrop
];
}
NSLog(@"Test");
[self.myViewController presentViewController: activityVC animated: YES completion: nil];
}
在BlogView.m中
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
object:(PFObject *)object
{
static NSString *CellIdentifier = @"Cell";
Cell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[Cell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
self.theObject = object;
// Configure the cell to show todo item with a priority at the bottom
cell.profileName.text = object[@"Title"];
cell.contentLabel.text = object[@"Request"];
cell.firstName = object[@"FirstName"];
cell.lastName = object[@"LastName"];
cell.iostoken = object[@"DeviceID"];
cell.request = object[@"Title"];
cell.prayerObject = object;
PFFile *thumbnail = object[@"ProfilePic"];
cell.profilePic.image = [UIImage imageNamed:@"AppIcon60x60@2x.png"];
[thumbnail getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
UIImage *thumbnailImage = [UIImage imageWithData:imageData];
UIImageView *thumbnailImageView = [[UIImageView alloc] initWithImage:thumbnailImage];
cell.profilePic.image = thumbnailImage;
}];
NSString *dates = object[@"dateMade"];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MMM_dd_yyyy"];
NSDate *datefromstring = [formatter dateFromString:dates];
NSDateFormatter *formatter2 = [[NSDateFormatter alloc] init];
[formatter2 setDateFormat:@"MMM dd, yyyy"];
cell.dateLabel.text = [formatter2 stringFromDate:datefromstring];
UIFont *cellFont = [UIFont fontWithName:@"Verdana-Bold" size:15];
UIFont *cellFont2 = [UIFont fontWithName:@"Verdana-Bold" size:12];
return cell;
}
我没有收到任何警告或错误,但是当我点击按钮时,没有任何反应。
答案 0 :(得分:2)
第一步:从您单元格上的按钮获取一个IBOutlet到CustomCell.h文件......
@property (weak, nonatomic) IBOutlet UIButton *commentButton;
第二步:在cellForRowAtIndexPath中,为每个单元格上的按钮添加一个选择器并按照您想要的方式装扮...... 注意我们正在添加选择器到每个单元格按钮&#39;现在......不是self.commentButton
[cell.commentButton addTarget:self action:@selector(didTapCommentButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[cell.commentButton setTitle:@"Share" forState:UIControlStateNormal];
[cell.commentButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell.commentButton setTitleColor:[UIColor greenColor] forState:UIControlStateHighlighted];
第三步:在BlogView.m文件中实现选择器方法,而不是在CustomCell.m内部实现
