  • UIImageView not displaying image when property is set too early

    - by Undeadlegion
    I have an image I want to display inside a UIView. In Interface Builder, the UIView is the root and a UIImageView is its child. The view is connected to view controller's view outlet, and the image view is connected to the image view outlet: @property (nonatomic, retain) IBOutlet UIImageView *imageView; If I try to set the image property of UIImageView before it's visible, the image doesn't show up. TestView *testView = [[TestView alloc] initWithNibName:@"TestView" bundle:nil]; testview.imageView.image = [logos objectAtIndex:indexPath.row]; [self.navigationController pushViewController:testView animated:YES]; If, however, I pass the image to the controller and set the image property in view did load, the image becomes visible. TestView *testView = [[TestView alloc] initWithNibName:@"TestView" bundle:nil]; testview.image = [logos objectAtIndex:indexPath.row]; [self.navigationController pushViewController:testView animated:YES]; - (void)viewDidLoad { [super viewDidLoad]; imageView.image = image; } What is causing the image to not show up in the first scenario?

  • Fake location for the device (custom)

    - by AtomRiot
    I know there are a few apps out there to fake a devices location but specifically what i want to do is use a location grabbed from a url. What direction should I look for setting the location on the device. The scenario i have is a jailbroken Wi-Fi iPad tethered to a nexus one. The nexus one would host a background service that when a request is recieved, it would respond with gps data of its current location. The jailbroken ipad would have a background service that either updated the location on a time interval, or on a per request basis (depending on how i have to implement it) by submitting a request to the tethered nexus one service. That data would then be set on the ipad and an application requesting location would get the service data. The goal is to recreate the location faker app's functionality with the exception of the spoofed location comes from the nexus ones gps via the service but i have not yet found out how to set the location data for the device. I can ofcourse implement this in a per app basis but it would be awesome to have any app be able to use it.

  • Changing UITableViewCell height on a grouped cell doesn't look good

    - by Sheehan Alam
    I have a UITableView with 3 sections. In the first section I have 2 grouped cells. I am modifying the first cell to be larger than the second. Though the first cell resizes, it seems to mess up the cell below it. How can I resolve this? - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight; if(indexPath.section == kBioSection) { switch(indexPath.row) { case kBioSectionDescriptionRow: rowHeight = 100; break; } } else { rowHeight = 50; } return rowHeight; }

  • Why won't my UITableViewCell deselect and update its text?

    - by Josh
    I have a UITableView with a list of stories and a cell at the bottom that loads more stories. I am trying to make the "More Stories..." cell deselect and change its text to "Loading..." when clicked. I have searched all over the internet and all over stackoverflow and I cant figure out why my code isnt working right. Right now, when the "More Stories..." cell is clicked, it stays selected and doesnt ever change its text. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; if (storyIndex == [stories count]) { UITableViewCell *moreCell = [tableView dequeueReusableCellWithIdentifier:@"more"]; if (moreCell == nil) { moreCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"more"] autorelease]; } // Set up the cell moreCell.textLabel.text = @"Loading..."; [tableView deselectRowAtIndexPath:indexPath animated:YES]; [self moreStories]; } else { NSLog(@"%@",[[stories objectAtIndex: storyIndex] objectForKey: @"link"]); webViewController *webController; webController = [[webViewController alloc] initWithURLPassed:[[stories objectAtIndex: storyIndex] objectForKey: @"link"]]; [self.navigationController pushViewController:webController animated:YES]; [webController release]; webController =nil; self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil]; } }

  • 03/20/11 11:24 AM(MONTH/DATE/YEAR HOUR:MIN)

    - by The deals dealer
    I am using the below code: NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateStyle:NSDateFormatterFullStyle]; NSDate *today=[NSDate date]; NSString *string = [dateFormatter stringFromDate:today]; NSLog(@"%@",string); [dateFormatter release]; This will not give me this format 03/20/11 11:24 AM(MONTH/DATE/YEAR HOUR:MIN), if i convert system date and time so the converted string should have such type of information 03/20/11 11:24 AM(MONTH/DATE/YEAR HOUR:MIN).? What should i do?

  • Is there any difference in the implementation of these three validation methods?

    - by dontWatchMyProfile
    Core Data is calling these methods in certain situations: - (BOOL)validateForInsert:(NSError **)outError; - (BOOL)validateForUpdate:(NSError **)outError; - (BOOL)validateForDelete:(NSError **)outError; I wonder if they're doing anything different, or if they're essentially doing the exact same things. As far as I know, these methods call the -validateValue:forKey:error: method once for every property. The only difference I can imagine is in the .validateForDelete: method. I see no reason why to validate an object when it shall be deleted, except for applying delete rules, probably only in the case of the DENY rule.
