BUG IN CLIENT OF LIBTRACE: don't close random fds
I am new to objective c. Thanks in advance for your valuable time.
It looks like the NSURL shared cache uses SQLite for its on-disk storage. I did not know that. Interesting.
I'm guessing this call is not happening on the main thread. If that's true, then this backtrace raises a number of red flags for me, because SQLite is not thread-safe by default, and I've seen fascinating database corruption and other bugs when one assumes that it is.
I'd try explicitly calling [NSURLCache sharedURLCache] from your main thread before spawning this code, and see if the problem goes away. If not, you probably have a corrupt cache database on disk.

I have created a WCF Service to insert data in sql server, so that why I have followed the below structure.
I created first the method and his Implementation;
In WCF interface:
[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "json/InsertEmployee/{id1}/{id2}/{id3}")]
bool InsertEmployeeMethod(string id1,string id2, string id3);
In Implementation:
public bool InsertEmployeeMethod(string id1, string id2, string id3)
{
int success = 0;
using (SqlConnection conn = new SqlConnection("Data Source=NXT1;User ID=zakaria;Password=11;Initial Catalog=EmpDB;Integrated Security=false"))
{
conn.Open();
decimal value = Decimal.Parse(id3);
string cmdStr = string.Format("INSERT INTO EmpInfo VALUES('{0}','{1}',{2})", id1, id2, value);
SqlCommand cmd = new SqlCommand(cmdStr, conn);
success = cmd.ExecuteNonQuery();
conn.Close();
}
return (success != 0 ? true : false);
}
to test the web service, try that URL:
"41.142.251.142/JsonWcfService/GetEmployees.svc/json/InsertEmployee/myName/MylastName/6565"
until here all is working well,
So to test this web servcie, I created in my Main.storyboard 3 textFields (firstName.text and lastName.text and salary.text and a button to send the data entered). note that I have worked with xcode 5 and ios 7.
I declared the url inside my viewcontroller.m as following:
myViewController.m:
#define BaseWcfUrl [NSURL URLWithString:#"41.142.251.142/JsonWcfService/GetEmployees.svc/json/InsertEmployee/{id1}/{id2}/{id3}"]
Then I implemented the Insert Employee Method related to click button.
-(void) insertEmployeeMethod
{
if(firstname.text.length && lastname.text.length && salary.text.length)
{
NSString *getValue= [BaseWcfUrl stringByAppendingFormat:#"InsertEmployee/%#/%#/%#",firstname.text,lastname.text,salary.text];
NSURL *WcfServiceURL = [NSURL URLWithString:getValue];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:WcfServiceURL];
[request setHTTPMethod:#"POST"];
// connect to the web
NSData *respData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
// NSString *respStr = [[NSString alloc] initWithData:respData encoding:NSUTF8StringEncoding];
NSError *error;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:respData
options:NSJSONReadingMutableContainers
error:&error];
NSNumber *isSuccessNumber = (NSNumber*)[json objectForKey:#"InsertEmployeeMethodResult"];
}
}
So the issue that I have encountered is that the system always return the str value as "Nil"
NSString *getValue= [BaseWcfUrl stringByAppendingFormat:#"InsertEmployee/%#/%#/%#",firstname.text,lastname.text,salary.text];
so you can see all the message error here :

can you please help me on that, i'm very stressed with.
much appreciate .
I think you just have the wrong URL, you're adding InsertEmployee twice.
Change BaseWcfUrl to just [NSURL URLWithString:#"41.142.251.142/JsonWcfService/GetEmployees.svc/json/"] instead of [NSURL URLWithString:#"41.142.251.142/JsonWcfService/GetEmployees.svc/json/InsertEmployee/{id1}/{id2}/{id3}"]
To be absolutely sure, log the final URL to the console (or look at it in the debugger) to make sure it's correct.
Also, in your code, in NSURL *WcfServiceURL = [NSURL URLWithString:str];, where is str coming from? Did you mean getValue there?
So I'm trying to run some terminal commands from my program, and I am getting some confusing errors.
Im a newer developer coming from Java, so I may be missing something.
Heres the code:
NSTask *task = [[NSTask alloc] init];
NSString *commitText = [commitMessage stringValue];
NSString *a = [NSString stringWithFormat:#"cd %#", dirPath];
NSString *c = [NSString stringWithFormat:#"git commit -m '%#'", commitText];
NSArray *commands = [[NSArray alloc]initWithObjects:a,
#"git add 'Project'",
c,
#"git push origin HEAD",
nil];
[task setLaunchPath:#"/bin/sh"];
// Do commands
NSArray *args = [NSArray arrayWithObjects:commands,
nil];
[task setArguments: args];
[task launch];
And here are the errors:

Thanks!
Your arguments array contains an array. It should be an array of strings. Use your commands object as that parameter for NSTask.
I think the problem is that your passing a array with a array of strings to setArguments. You should pass an array with strings only not an nested array.
But I think you misunderstand how the arguments to NSTask works. You should probably do something like this:
[task setArguments:[[[NSArray alloc] initWithObjects:
#"git", #"add", #"Project", nil]
autorelease]];
Etc, or if you really want to use sh you probably need to add some ; to separate the shell commands.

terminate called throwing an exception(lldb)
It says "file exists". Isn't that enough of a clue?
From the NSFileManager docs:
If a file with the same name already exists at dstPath, this method aborts the copy attempt and returns an appropriate error.
By the way, you should check the error after each copy, not once at the end because if an error occurs on the first copy, and the second copy, you'll lose the error information from the first copy.
Trying to create a request only to have a runtime error thrown. Method initiating the request:
- (void)loadMemberData {

NSMutableString *url = [[NSMutableString alloc] initWithString:appDelegate.apiURL];

//Create conn
NSURLRequest *request = [[NSURLRequest alloc] requestWithURL:tempURL];
NSLog(#"%#", request);
//conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
//[request release];
}
The URL logs correctly. I have even checked the object type to make sure everything is correct, and all seems good. No compile time errors or warnings. Stack Trace & Log:

You should be doing
NSURLRequest *request = [NSURLRequest requestWithURL:tempURL];
The requestWithURL: creates NSURLRequest objects that are autorelease-d.
The actual error message says "unrecognized selector" because requestWithURL: is a class method, but you are using it like an instance method.

terminate called after throwing an instance of 'NSException'
For the sake of anybody else running into this - it's likely that you're passing an NSManagedObject subclass to a method that wants an NSManagedObjectID. Check that your method signatures line up between .h and .m files.
It may not be the actual source of your problem; but ManagedObjectContexts are intended to used one per thread. If you want to access Core Data objects you have to use a separate context for each thread and pass IDs between them.

I got this issue by passing in the wrong ID to existingObjectWithID:error:. I was passing in the object's id when I should have used objectID.
