ObjectiveC Parse Integer from String

I really don't know what was so hard about this question, but I managed to do it this way:

[myStringContainingInt intValue];

It should be noted that you can also do:

myStringContainingInt.intValue;

You can just convert the string like that [str intValue] or [str integerValue]

integerValue Returns the NSInteger value of the receiver’s text.

(NSInteger)integerValue Return Value The NSInteger value of the receiver’s text, assuming a decimal representation and skipping whitespace at the beginning of the string. Returns 0 if the receiver doesn’t begin with a valid decimal text representation of a number.

for more information refer here

NSArray *_returnedArguments = [serverOutput componentsSeparatedByString:@":"];

_returnedArguments is an array of NSStrings which the UITextField text property is expecting. No need to convert.

Syntax error:

[_appDelegate loggedIn:usernameField.text:passwordField.text:(int)[[_returnedArguments objectAtIndex:2] intValue]];

If your _appDelegate has a passwordField property, then you can set the text using the following

[[_appDelegate passwordField] setText:[_returnedArguments objectAtIndex:2]];
