I have 

NSString *strAmount = @"10.00";
NSInteger totalAmount = totalAmount + [strAmount integerValue];

The output is

totalAmount = 80

but I want the output to be totalAmount = 10

  1. First of all totalAmount should not be of pointer type.
  2. Variable 'totalAmount' is uninitialized when used within its own initialization

replace your code with

NSString *strAmount = @"10.00";
NSInteger totalAmount =  0;
totalAmount = totalAmount + [strAmount integerValue];
 NSLog(@" %ld",(long)totalAmount);

Output = 10

why you did pointer to int?

NSInteger totalAmount 0;
totalAmount = totalAmount + [strAmount integerValue];

Replace NSInterger *total by NSInteger total or convert NSInteger to int (C based)

NSString *strAmount = @"10.00";

NSInteger totalAmount = 0;
totalAmount = totalAmount + [strAmount integerValue];
