NSArry of floats issue
Im trying to create an NSArray of floats. However, once the value is added to the arrays it is alway 0.0000000.
What am i doing wrong?
NSLog(@"percent: %f" , percent); prints the correct value and
NSLog(@"timeArray: %f", [timeArray objectAtIndex:i]); is always 0.00000.
NSMutableArray *timeArray = [[NSMutableArray alloc] initWithCapacity:count];
for (int i = 0; i < count; i++) {
int time 开发者_开发技巧= Counter->getTime(i);
float percent = (float)(time - startTime) / (float)endTime;
NSLog(@"percent: %f" , percent); // This prints correct value
[timeArray addObject:[NSNumber numberWithFloat: percent]];
NSLog(@"timeArray: %f", [timeArray objectAtIndex:i]); // This prints 0.00000
}
Im on the iphone and running out of memory, could that be causing it?
in the second NSLog, you are printing an NSNumber, not the float inside..to see that value..
NSLog(@"timeArray: %f", [[timeArray objectAtIndex:i] floatValue]);
try
NSLog(@"timeArray: %f", [[timeArray objectAtIndex:i] floatValue]);
at the end.
You're trying to print out the pointer to the NSNumber, not the value stored in it.
