I have a simple project where I have several NSStrings combined into one. Then, that string is copied to the clipboard. Here is the code:
#import "CopyToClipViewController.h"
#interface CopyToClipViewController ()
#end
#implementation CopyToClipViewController
#synthesize device;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
if (self.device) {
NSString *namevalue;
NSString *versionvalue;
NSString *companyvalue;
namevalue = [self.device valueForKey:#"name"];
versionvalue = [self.device valueForKey:#"version"];
companyvalue = [self.device valueForKey:#"company"];
NSString *shareString = [NSString stringWithFormat:#"I have performed %# minutes of %# %#",namevalue, versionvalue, companyvalue];
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
pasteboard.string = shareString;
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
However, after I build and run the project in the simulator, I can't seem to paste the string into any other app. What is the issue? Thanks in advance!
I think you can paste it only in simulator-open some app with textfield and longpress the textfield. Tap paste

Here is the screen of my nib file and map view but the map is always taking the whole view.I tried resetting my simulator and cleaning my Xcode but nothing works.Am i doing something wrong?
Do i need to give mapview a frame programmatically?
http://prntscr.com/1sy1bw
I also want the button to be on top of mapview if the map cannot be set to take a particular frame.
Consider the below code please:
#import "mapViewController.h"
#interface mapViewController ()
#end
#implementation mapViewController
#synthesize mapView,source,dest,latdest,latsource,longdest,longsource;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
dest=#"delhi";
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0,0,160,240)];
CLGeocoder *geocoder1 = [[CLGeocoder alloc] init];
[geocoder1 geocodeAddressString:source
completionHandler:^(NSArray* placemarks, NSError* error)
{
for (CLPlacemark* aPlacemark in placemarks)
{
coordinate.latitude = aPlacemark.location.coordinate.latitude;
latsource=&coordinate.latitude;
coordinate.longitude = aPlacemark.location.coordinate.longitude;
longsource=&coordinate.longitude;
MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
[annotation setCoordinate:(coordinate)];
[annotation setTitle:source];
annotation.subtitle = #"I'm here!!!";
mapView.delegate = self;
[self.mapView addAnnotation:annotation];
}
}];
}
- (void)viewDidLoad
{
[super viewDidLoad];
//mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0,0,160,240)];
CLGeocoder *geocoder1 = [[CLGeocoder alloc] init];
[geocoder1 geocodeAddressString:source
completionHandler:^(NSArray* placemarks, NSError* error)
{
for (CLPlacemark* aPlacemark in placemarks)
{
coordinate.latitude = aPlacemark.location.coordinate.latitude;
latsource=&coordinate.latitude;
coordinate.longitude = aPlacemark.location.coordinate.longitude;
longsource=&coordinate.longitude;
MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
[annotation setCoordinate:(coordinate)];
[annotation setTitle:source];
annotation.subtitle = #"I'm here!!!";
[self.view addSubview:mapView];
[self.mapView addAnnotation:annotation];
}
}];
}
I commented the mapview alloc codeline and this fixed the issue.Seems like mapview gets pushed as soon as its allocated memory space.Moreover the frame coordinated that i initialised mapviewview with are still preserved although the code is commented.Dont know if it should work this way only or not but it did solved my issue .
I am doing master + detail pages. I have successfully made tapping the cell rows in the master page jump to detail page, using the code below
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"MasterToDetail" sender:indexPath];
}
However becuase my master page cell rows also have accessory buttons, i need to make these buttons able to jump to the detail page too through tapping. So i implemented code
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"MasterToDetail" sender:self];
}
Howver the details dispalyed is not correct. It always shows the first detail data in the datalist. I changed sender:self to sender:indexPath also no working.
I used stackoverflow answers from here and here. I am a beginner, so some concepts still no clear sorry.
Edited

This is due to following statement
SearchDataDetail *bug = [self.bugs objectAtIndex:self.tableView.indexPathForSelectedRow.row];
In this self.tableView.indexPathForSelectedRow.row will work only for only for row selection
not for accessoryButton tap.
You can solve it by two easy way
Declare a variable in .h file to store indexPath and use it to pass selected indexPath.
Pass indexPath in sender
All the best..
Im trying to get a scanned QR code to display a view controller with information about the item the code represents. When I try and segue to the detail view controller, it comes up with:
Warning: Attempt to present <MachinesDetailViewController: 0x1e5bfc50> on <UITabBarController: 0x1f867d90> whose view is not in the window hierarchy!
The MainViewController is withing a main tab bar controller, but the detail view controller is within a navigation controller which is withing the tab bar controller.
Heres my MainViewController.m where this is sitting.

The ZBar stuff is just relating to the QR scanning API.

Thanks, if you need more info just ask.

Struggled with the exact same issue,
my solution was to call the segue this way:
[reader dismissViewControllerAnimated:YES completion:^{
NSLog(#"Perform segue");
[self performSegueWithIdentifier:#"showDetailFromMain" sender:self];
}];
I also had to connect the segue to the view and not to a single button.
Hope this works for you.
I am erroring out with Bool and before I added a modal view and now it says bool is undefined. I dont understand why that is unless its because I'm using another nib for my modal view.
Do I need to call or change my boon now. Please advise.

You need a closing curly brace on doneButtonPressed:.

The colon (:) is part of the name of the method, but you haven't included it in the error message. It may be that you just forgot, but if you're calling -switchChanged (no colon) from somewhere, or if you connected a control using the action -switchChanged (no colon), that's the problem. Perhaps you added the colon and sender parameter later on?
