Displaying Integer value in a Label , int to String conversion?

Question

How to display an integer value in a UILabel in ViewDidLoad? I did for text and date and image but how to convert int to string. I was trying with following code

 NSString* label=[aa stringWithFormat:@"%d",((Comments *) [self.list objectAtIndex:0]).noofcomm]]; 
 [self.comments2 setText:label];

but didn't work.Please help me.How to set with the Integer with UILabel?

This is my comments.h

    @interface Comments : NSObject
{
    NSInteger iD;
    UIImage *photo;
    NSString *name;
    NSString *descrp;
    NSDate *date;
    NSString *msg;
    NSInteger noofcomm;
    NSInteger nooflikes;
}
@property(nonatomic,assign)NSInteger iD;
@property(nonatomic,retain)UIImage *photo;
@property(nonatomic,retain)NSString *name;
@property(nonatomic,retain)NSString *descrp;
@property(nonatomic,strong)NSDate *date;
@property(nonatomic,retain)NSString *msg;
@property(nonatomic,assign)NSInteger noofcomm;
@property(nonatomic,assign)NSInteger nooflikes;

Answer 1

NSInteger someInteger = myInteger;
NSString *someString = [NSString stringWithFormat:@"%d", someInteger];
myLabel.text = someString;

or

NSNumber *someNumber = @(myInteger);
NSString *someString = [someNumber stringValue];
myLabel.text = someString;

Both will work.

EDIT:

In your case, it will be something like this:

NSInteger someInteger = ((Comments *) [self.list objectAtIndex:0]).noofcomm;
NSString someString = [NSString stringWithFormat:@"%d", someInteger];
self.comments2.text = someString;

If it's still not working, FOR SURE the problem is somewhere else, and not with the conversion. Check with property noofcomm has a valid value, check if your label reference is ok (test with a random value before the conversion), and somethings like that.

Answer 2

You need to build an NSString

int someInteger = 10;
NSString *someString = [[NSString alloc] initWithFormat:@"%d", someInteger];

Answer 3

You can use something like [NSString string_from_int:42] in LCategory since 0.1.3: https://github.com/superarts/LCategory

Answer 4

_lbl_yourLabel.text=[NSString stringWithFormat:@"%d",[[dic valueForKey:@"your integer value"] intValue]];

On the top left is your label named "yourLabel" , "dic" is your json response dictionary where all the data is coming in key value terms, "your integer value" is the key for which the value will be assign to the label "yourLabel", we have taken intValue because we cannot assign integer value directly to the label.

or you also can try below:

int anyInteger = 13;
NSString *yourString = [[NSString alloc] initWithFormat:@"%d", anyInteger];
self.yourLabel.text = yourString;
