Convert NSString to NSInteger?

Question

I want to convert string data to NSInteger .

Answer 1

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

 NSInteger myInt = [myString intValue]; 

Answer 2

[myString intValue] returns cType "int"

[myString integerValue] returns a NSInteger .

In most cases, I find these simple functions by looking at links to apple classes, the fastest way to get the [option] button pressed and double-click class declarations (in this case NSString).

Answer 3

I found this to be the correct answer.

 NSInteger myInt = [someString integerValue]; 

Answer 4

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

returns NULL if string or returns NSNumber

 NSInteger intValue=[tempVal2 integerValue]; 

returns an integer NSNumber

Answer 5

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

Answer 6

it is safer than integerValue:

 -(NSInteger)integerFromString:(NSString *)string { NSNumberFormatter *formatter=[[NSNumberFormatter alloc]init]; [formatter setNumberStyle:NSNumberFormatterDecimalStyle]; NSNumber *numberObj = [formatter numberFromString:string]; return [numberObj integerValue]; } 

Answer 7

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