change this into
updated answer
#interface myViewController : UIViewController <UIAlertViewDelegate>
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSError* error111;
json111 = [NSJSONSerialization JSONObjectWithData: mutableData
options:kNilOptions
error:&error111];
NSLog(#"%#",json111);
NSArray *temp = [ json111 objectForKey:#"Currencies"];
// you can directly fetch like
NSDictionary *fetchDict = [temp objectAtIndex:0];
NSDictionary *fetchUnit = [temp objectAtIndex:1];
// finally you can fetch like
NSString * total = [fetchDict objectForKey:#"total"];
NSString * one_unit = [fetchUnit objectForKey:#"one_unit"];
//updated
NSString *final = [NSString stringWithFormat:#"%# , %#", total,one_unit];
// in here you can assign the value to Alert
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Value"
message:final
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"ok", nil];
alert.tag = 100;
[alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (alertView.tag == 100)
{
if (buttonIndex == 0)
{
// ok button pressed
//[self sendDataToServer :#"POST" params:str];
}else
{
// cancel button pressed
}
}

You should know the basics of NSString, refer here.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Value"
message:[NSString stringWithFormat:#"%#", str]
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"ok", nil];

Answer 3

You can save your response in an NSString and then pass this string in the message field of your alert view.
However, as of iOS 8,
UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead

Answer 4

Change your Alert View as following :
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Value"
message:[NSString stringWithFormat:#"Response Message : %#",str]
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"ok", nil];
This will display your response message instead %#..
If you want to send Data to Server on Click on alertView, you need to write code in alertView Delegate clickedButtonAtIndex
Hope it helps..
