viewDidLoad becomes an infinite loop. HELP

This is probably the easiest/lamest question.

So I am trying to initialize an array with values 0 to 3 increments of 0.25 in the viewDidLoad method, and I can see an infinite loop here开发者_高级运维.

NSArray *pickArray3 = [[NSMutableArray alloc] init];
int i = 0;
//for(i = 0.25; i<=3; i=i+0.25) 
while (i<3)
{ 
//NSString *myString = [NSString stringWithFormat:@"%d", i]; 
    i=i+0.25;
    NSLog(@"The Value of i is %d", i );
//[pickArray3 addObject:myString]; // Add the string to the tableViewArray.
 }
NSLog(@"I am out of the loop now");
self.doseAmount=pickArray3;
[pickArray3 release];

And This is the Output.

   2011-06-01 11:49:30.089 Tab[9837:207] The Value of i is 0
   2011-06-01 11:49:30.090 Tab[9837:207] The Value of i is 0
   2011-06-01 11:49:30.091 Tab[9837:207] The Value of i is 0
   2011-06-01 11:49:30.092 Tab[9837:207] The Value of i is 0
   // And this goes on //   
   // I am out of the loop now does not get printed //

Your i is an integer, it will never increment adding 0.25. Use a float or double.

**float** i = 0;
//for(i = 0.25; i<=3; i=i+0.25) 
while (i<3)
{ 
//NSString *myString = [NSString stringWithFormat:@"**%f**", i]; 
    i=i+0.25;
    NSLog(@"The Value of i is **%f**", i );
//[pickArray3 addObject:myString]; // Add the string to the tableViewArray.
 }

i is an int. Therefore 0+0.25 = 0.

use float instead of int .

because every time the expression value i+0.25 => (0 + 0.25 ) => 0.25.

i = i+0.25;

Now you are assigning the value 0.25 to integer therefore it become 0 every time and condition in while will never be false with 0 , So it goes to infinite loop.

So your code must be

float i = 0;
//for(i = 0.25; i<=3; i=i+0.25) 
while (i<3)
{ 
//NSString *myString = [NSString stringWithFormat:@"%d", i]; 
    i=i+0.25;
    NSLog(@"The Value of i is %f", i );
//[pickArray3 addObject:myString]; // Add the string to the tableViewArray.
 }
