can I store an id value in array of float type ?
- by srikanth rongali
I used,
for(id value in values) to get the value from an NSArray. Now I want to store it in 2 dimensional float array[][]. When I try to assign the values to array it is giving error:incompatible types in assignment.
I tried to cast the value but I got error: pointer value used where a floating point value was expected. I need to store the values in an 2 dimensional array . How can I make it ?
Thank You.
@implementation fromFileRead1
NSString *fileNameString;
int numberOfEnemies, numberOfValues;
-(id)init
{
if( (self = [super init]) )
{
NSString *path = @"/Users/sridhar/Desktop/Projects/exampleOnFile2/enemyDetals.txt";
NSString *contentsOfFile = [[NSString alloc] initWithContentsOfFile:path];
NSArray *lines = [contentsOfFile componentsSeparatedByString:@"\n"];
numberOfEnemies = [lines count];
NSLog(@"The number of Lines: %d", numberOfEnemies);
for (id line in lines)
{
NSLog(@"Line %@", line );
NSString *string1 = line;
NSArray *split1 = [string1 componentsSeparatedByString:@","];
numberOfValues = [split1 count];
NSLog(@"The number of values in Row: %d", numberOfValues);
for (id value in split1)
{
NSLog(@"value %@", value);
float value1;
value1 = [split1 objectAtIndex:2]);
NSLog(@"VAlue of Value1 at index 2: %f", value1 );
}
}
}
return self;
}
@end
In enemyDetal.txt I have
1,3,3
2,3,2.8
10,2,1.6
