Question

NSUInteger arrayLength = [annotations count];

    UILabel* arrayLengthLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 200, 100)];
    arrayLengthLabel.text = @"%@", arrayLength;
    [self.view addSubview:arrayLengthLabel];

I have the above code, which I have researched.

The problem is when outputting the arrays length count to the label.

I should have 4 elements in the array, but this is not outputting the number of elements, and I am sure I am making a schoolboy error here.

Cheers for help in advance

Answer 1

Here is the code I would use:

int arrayLength = [annotations count];
UILabel* arrayLengthLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 200, 100)];
arrayLengthLabel.text = [NSString stringWithFormat:@"%i",arrayLength];
[self.view addSubview:arrayLengthLabel];

I’m using a standard int and using the code %i instead of %@. This may be your issue. I don’t know offhand if an NSUInteger requires %i, but I definitely know int uses %i.

Also, I don’t know if your way of doing an NSString works without testing, so I’ve used the “full” format, which I know definitely works.
