I am getting warning [UIApplication delegate] must be used from main thread only in the below line of code
((AppDelegate *)[[UIApplication sharedApplication]
delegate]).loginProfile.accessToken;
Following is my code.
+ (NSString *)accessTokenHashForDate:(NSDate *)date withParameters:(NSArray *)params{
NSString *accessToken = ((AppDelegate *)[[UIApplication sharedApplication] delegate]).loginProfile.accessToken;
NSString *paramsStr = [params componentsJoinedByString:#""];
NSString *hashStr = [NSString stringWithFormat:#"%#%#%#%#", [CommonUtil IMEI], [date agileHashFormattedString], (!paramsStr) ? #"" : paramsStr, accessToken];
return hashStr
}
Can anyone tell me how to remove this warning message?

I need some help in passing data from AppDelegate to another controller which is a Table View Controller. In AppDelegate , i have a server response which i converted it to string. What i want is to pass that string to the another controller(Table View Controller) and display it to the Cell.

U can try this, i'm not sure if it work but hope it help
In AppDelegate.h: Add property to that stuff u want to pass, eg. #property (strong, nonatomic) NSString *string;
In AppDelegate.m: Assign value to it
In YourVC.m:
#import "AppDelegate.h"
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *yourString = [appDelegate string];
You have your data in Appdelegate now. Just create an object of it in file(Table view for you) where you need data and you can access your data now anywhere you want in that project.
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSlog(#"appDelegate.fechedArray==%#",appDelegate.fechedArray);
in AppDelegate.h
#define XAppDelegate ((AppDelegate *)[[UIApplication sharedApplication] delegate])
#interface AppDelegate : UIResponder <UIApplicationDelegate>
#end
and now you can access to your AppDelegate everywhere like this :
XAppDelegate.something
I need to upload an Image to the sever, and have to request in the background in case of the user press the home button.

[re setRequestMethod:#"POST"];
[re setDidFinishSelector:#selector(finish:)];
[re setDidFailSelector:#selector(failed:)];
// [re startAsynchronous];
[re startSynchronous];
}
In case the request is failed, I let it request automatically:
- (void)failed:(ASIFormDataRequest *)request
{
NSLog(#"error %#",request.error);
[self performSelector:#selector(uploadIDImageWithImage:) withObject:nil afterDelay:REQUEST_AGAIN_TIME];
// [SVProgressHUD showImage:nil status:#"验证提交成功，等待审核"];
}
When I press the home button, it may works but it can be out of time sometimes. When it fails, it won't request again! If the request asynchronous, it won't work until I enter the foreground again.
How can I fix it?
I put the code
[[UIApplication sharedApplication] endBackgroundTask:_uploadImageTask];
_uploadImageTask = UIBackgroundTaskInvalid;
in the success method finish:, it seems worked:
If there are other methods or any problem in this way, please let me know, thanks!

I can get log: "task 1a" ! but why I can't receive "task connect receive" ????
What should I do ?
Thanks.
To use a delegate for either NSURLConnection or CLLocationManager you'll need to create them as properties with a strong reference. Otherwise the delegate implementation will not get called. Since you did not provide the part where you declared those that may be the problem.
NSString* pp =[NSString stringWithFormat:#"xxxx.xx/xx.cshtml, newLocation.coordinate.latitude, newLocation.coordinate.longitude,0.0];
NSURL* response =[NSURL URLWithString:pp];
NSString* response_str =[NSString stringWithContentsOfURL:response encoding:NSUTF8StringEncoding error:nil];
NSLog(#"%#, response of report=%#", pp, response_str);
If I rewrite the code in didUpdateLocations as above,
I can get response_str and it is correct!
But question is: How can it pass ssl https without be challenged ??
even if it ready work very well!
I wonder whether it is possible to have multiple downloads when background fetch is happening (iOS7 Background Fetch).
Currently I have an app which download data from around 6 RESTful api. These API calls use NSURLSession and download data parallelly. This works when the app is in foreground. I have implemented the background fetch feature with my application where app can update while it's in background. Unfortunately when background fetch is happening only the first API is calling six time. I really appreciate if anyone can help me on this.
This is the code for download tasks.

Finally I found an answer by my self. If I use default delegate then the problem is solved. I afraid don't know the reason behind why the background fetch doesn't work with custom delegates when concurrently downloading.
NSURLSession *session = [NSURLSession sharedSession];
for (int i=0; i<[self.apiList count]; i++) {
BSJSONInfo *fdi = [self.apiList objectAtIndex:i];
NSURLSessionTask *downloadTask = [session downloadTaskWithURL:[NSURL URLWithString:fdi.downloadSource] completionHandler:^(NSURL *url, NSURLResponse *response, NSError *error){
NSData *d = [NSData dataWithContentsOfURL:url];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:d options:0 error:nil];
}];
[downloadTask resume];
}
I am trying to call alert view first then go to NSManagedObject. But when i click on button then it skip alert view and call this at the end of rest code.
Any one know's how can i force this uialertview to load first

[_alert show] displays the alert window and returns immediately. The "selection block"
is then called when an alert item has been pressed, or the "cancel block" is called
when the Cancel button has been pressed.
Therefore you have to move the code that fetches the managed object into the "selection block":
[_alert configureSelectionBlock:^(NSIndexPath *selectedIndex){
NSLog(#"Index is = %d", selectedIndex.row);
// ...
// Fetch object depending on selectedIndex.
// ...
} andCompletionBlock:^{
NSLog(#"Cancel Button Pressed\nNo Cells Selected");
}];
