Convert NSString to NSInteger?

Question

I want to convert string data to NSInteger.

Answer 1

NSNumber *tempVal2=[[[NSNumberFormatter alloc] init] numberFromString:@"your text here"];

returns NULL if string or returns NSNumber

NSInteger intValue=[tempVal2 integerValue];

returns integer of NSNumber

Answer 2

int myInt = [myString intValue];
NSLog(@"Display Int Value:%i",myInt);

Answer 3

If the string is a human readable representation of a number, you can do this:

NSInteger myInt = [myString intValue];

Answer 4

[myString intValue] returns a cType "int"

[myString integerValue] returns a NSInteger.

In most cases I do find these simple functions by looking at apples class references, quickest way to get there is click [option] button and double-click on the class declarations (in this case NSString ).

Answer 5

I've found this to be the proper answer.

NSInteger myInt = [someString integerValue];

Answer 6

NSString *string = [NSString stringWithFormat:@"%d", theinteger];
