I have some problems on save the position of switch,any help?
- (IBAction)SWitchActionAño:(id)sender {
NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
if (switchAño.on) {
[standardDefaults setBool:YES forKey:#"SwitchState"];
NSDateFormatter *formatter=[[NSDateFormatter alloc]init];
[formatter setDateFormat:#"MMM dd,yyyy HH:mm"];
diadelasemanalabel.text=[formatter stringFromDate:[NSDate date]];
} else {
[standardDefaults setBool:NO forKey:#"SwitchState"];
Año.text=#"";
}
}
but i have the problem here! I dont know what is the property!
- (void)viewDidLoad
{
[super viewDidLoad];
NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
//the error here:property switchAño not found on object....
if ([standardDefaults objectForKey:#"SwitchState"])
self.switchAño.on =[standardDefaults boolForKey:#"SwitchState"];
Try this in viewDidLoad
-(void)viewDidLoad {
[super viewDidLoad];
NSUserDefaults *standardDefaults = [[NSUserDefaults standardUserDefaults];
if ([standardDefaults boolForKey:#"SwitchState"] == YES) {
self.switchAño.on = YES;
}
else {
self.switchAño.on = NO
}

I have a working code, but now find the need to import & save two different Sqlite files via email "Open in" option, I tried using UIAlertView to create to different save file paths but it only seems to work with one way
- (void)handleOpenURL:(NSURL *)urlx {
NSData *dbimport = [[NSData alloc] initWithContentsOfURL:urlx];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:dbimport forKey:#"import"];
[defaults synchronize];
NSLog(#"import saved");
databaseName = #"svrStoreData2.sql";
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSError *writeError = nil;
NSString *filePathx = [documentsPath stringByAppendingPathComponent:databaseName]; [dbimport writeToFile:filePathx atomically:YES];
if (writeError)
{
NSLog(#"Error writing file: %#", writeError);
}
}
Both file have specific file names so was wonder if I could use "if equal to string" & use an if statement after I have synchronised NSUserDefaults to give two file path save options
Thanks for any help in advance
This was my UIALertView try

It looks like you have muddled up your pointers. You have two references to the same instance of userDefaults yet you expect different results when writing to each one. Here, lets walk through your code
NSString *rejected=self.rejectLabel.text;
int reject=intToString(self.rejectLabel.text);
NSString *accepted=self.acceptedLabel.text;
NSUserDefaults *rejectTry=[NSUserDefaults standardUserDefaults];
Lets stop here. standardUserDefaults is a singleton object. You are not creating a user defaults object when you call this method. You then go on to set a value
[rejectTry setObject:self.rejectLabel.text forKey:REJECTIONS];
This works fine.
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:self.rejectLabel.text forKey:REJECTIONS];
Now you have written over your previous value!
[[NSUserDefaults standardUserDefaults] setValue:#"reject" forKey:REJECTIONS];
And you do it again!
[[NSUserDefaults standardUserDefaults] setValue:self.rejectLabel.text forKey:REJECTIONS];
[[NSUserDefaults standardUserDefaults] setObject:#"accepted" forKey:ACCEPTED];
Conclusion
What you should be doing is creating a local variable like this NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; Then use this for all your writes. Then you will see how you are overwriting the value with key REJECTIONS multiple times
hi i am trying to store my username and password in my app with NSUserdefaults and checkbox.
my code is ..
In viewdidload
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:UserText.text forKey:#"infoString"];
[defaults setObject:PasswdText.text forKey:#"infoString1"];
[defaults synchronize];
UserText.text=[[NSUserDefaults standardUserDefaults] objectForKey:#"infoString"];
and
- (IBAction)checkButton:(id)sender {
if (!checked) {
[checkBoxButton setImage:[UIImage imageNamed:#"checkbox_ticked.png"] forState:UIControlStateNormal];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
self.UserText.text=[defaults objectForKey:#"infoString"];
self.PasswdText.text = [defaults objectForKey:#"infoString1"];
checked = YES;
}
else if (checked) {
[checkBoxButton setImage:[UIImage imageNamed:#"checkbox_not_ticked.png"] forState:UIControlStateNormal];
checked = NO;
}
}
and my result is if i click checkbox means my textfield is refreshed.where i made mistake?
thanks in advance.
You should save the values in NSUserDefaults when User Performed Submit action, Like this
- (void)submitButtontapped {
if (checked) {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:UserText.text forKey:#"infoString"];
[defaults setObject:PasswdText.text forKey:#"infoString1"];
[defaults synchronize];
UserText.text=[[NSUserDefaults standardUserDefaults] objectForKey:#"infoString"];
}
// do the next thing
}
- (IBAction)checkButton:(id)sender {
if (checked) {
checked = NO;
[checkBoxButton setImage:[UIImage imageNamed:#"checkbox_not_ticked.png"] forState:UIControlStateNormal];
} else {
checked = YES;
[checkBoxButton setImage:[UIImage imageNamed:#"checkbox_ticked.png"] forState:UIControlStateNormal];
}
}
I am working on a project that has a simple tableview with detail view.
Data source is a plist. I am trying to allow user input to be saved into the plist and shown in tableview. i have created a add view controller which gets presented and dismissed modally and has two text fields which allow the user to add the name of the city and name of the states, also a text field to input description.
Problem: how to save this data to my existing plist and show it in the tableview. Here is my code for the table view:
#implementation TableViewController
#synthesize content, searchResults;

i know there are tons of almost similar questions and believe me i have looked at so many of them and i think i am hitting the wall with this one and i cant think of a proper way to do this. it may be so simple but for the life of me i cant figure this out and thats why i am trying to ask for help. i truly appreciate any help i can get. if needs be i can place the sample project on git hub for ease of access. also the project is built in ios 6 and the latest Xcode.
P.S. here is the link to the project on git hub: https://github.com/AdrianPhillips/TableSearch
I can't find your code that do the actual "save" work. I guess it should be in the UIAlertView delegate,right ? And you did not tell us what's your problem. Following code maybe what's you seeking.
[content writeToFile:filePath atomically:YES]
Another reminder is: you should NOT save the plist back to main bundle, save it to Documents or Cache or other folder.
Just as every one has pointed out you can not write to the plist that is in your main bundle. You need to copy it from the bundle to your application document directory. Then you can just init from and write to the path in your documents directory. The other issue you have, is that nothing is communicating the new data from the AddViewController back to the TableViewController. You should create a protocol and delegate for your AddViewController.
For all the gore details see my pull request on GitHub.
https://github.com/GayleDDS/TableSearch.git
You have to copy the plist to the Documents folder first. You can't edit it into the original app folder. You can use this class to do this:
- (void) CreatePlistCopyInDocuments:(NSString *)plistName {
// First, test for existence.
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writablePath = [documentsDirectory stringByAppendingPathComponent:plistName];
success = [fileManager fileExistsAtPath:writablePath];
if (success) {
return;
}
// The writable file does not exist, so copy from the bundle to the appropriate location.
NSString *defaultPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:plistName];
success = [fileManager copyItemAtPath:defaultPath toPath:writablePath error:&error];
if (!success) {
NSAssert1(0, #"Failed to create writable file with message '%#'.", [error localizedDescription]);
}
}
You have just to pass the plist name to it.
Then you have to load it into some NSMutableDictionary like this:
NSString *documents = [NSHomeDirectory() stringByAppendingString:#"/Documents"];
NSString *plistInDocuments = [documents stringByAppendingPathComponent:#"UserData.plist"];
NSMutableDictionary *plistData = [[NSMutableDictionary alloc]initWithContentsOfFile:plistInDocuments];
After you have updated the values for the dictionary, you have to write the file back to the documents like this:
[plistData writeToFile:plistInDocuments atomically:YES];
I'm new to Xcode and I'm having an issue, if you click the sound buttons multiple times they overlap each other. How would I set my code so that if you click a button while a sound is playing it will stop the current sound playing and start the new one.
If you could post the code it would be much appreciated.
Thanks,
Dominick
Here is a copy of my current code:
#import "Sound3ViewController.h"
#implementation Sound3ViewController
-(IBAction)playnow:(id)sender;{
soundFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"winning"
ofType:#"mp3"]];
sound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFile error:nil];
sound.delegate = self;
[sound play];
}
- (IBAction)play2:(id)sender {
soundFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"onadrug"
ofType:#"mp3"]];
sound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFile error:nil];
sound.delegate = self;
[sound play];
}
- (void)dealloc
{
[super dealloc];
[sound release];
[super dealloc];
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad

[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
I would suggest you to disallow playing the sound with a variable and schedule an action that allows it again after the duration of the file. Eg:
boolean allowed = true
-(IBAction)playnow:(id)sender
{
if (allowed) { // <--- ADD THIS
allowed = false;
soundFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"winning"
ofType:#"mp3"]];
sound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFile error:nil];
sound.delegate = self;
[sound play];
NSInvocation *invocation = [[NSInvocation alloc] init];
[invocation setTarget:self];
[invocation setSelector:#selector(allowPlaying)];
[NSTimer scheduledTimerWithTimeInterval:[sound duration] invocation:invocation repeats:NO];
} // <-- AND THIS
}
-(void)allowPlaying
{
allow = true;
}
Didn't test it since just wrote on the fly but you've got the general idea..
I'm new to objC also, so I'm not sure this is correct, but try this:
#import "Sound3ViewController.h"
#implementation Sound3ViewController
-(IBAction)playnow:(id)sender;{
soundFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]

// NEW STUFF
if (sound) {
if ([sound playing]) {
[sound stop];
}
[sound release];
}
sound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFile error:nil];
sound.delegate = self;
[sound play];
}
- (IBAction)play2:(id)sender {
soundFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]
