- (BOOL)boolValue
Return Value
The Boolean value of the receiver’s text. Returns YES on encountering one of "Y", "y", "T", "t", or a digit 1-9—the
method ignores any trailing characters. Returns NO if the receiver doesn’t begin with a valid decimal text representation of a number.


In the explanation of above method, i am unable to understand why it is only restrict to "Y", "y", "T", "t", or a digit 1-9....please reply me...

Because "Yes" and "True" are the common (in English) words for a "positive" boolean value. And since 0 is the common value for a "negative" or "false" boolean, any number other than 0 must result in a "positive" result.

Is there some reason you're just reading the API documentation and asking questions about it, rather than posting actual programming questions?
