Some time in our string some space is remain and so bitly not convert it and return null value so first remove the null or space from string and then try to convert it..
Add my these two methods in your .m file and then use with your variable.. see the example also how to use it...
-(NSString*) trimString:(NSString *)theString {
NSString *theStringTrimmed = [theString stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];
return theStringTrimmed;
}
-(NSString *) removeNull:(NSString *) string {
NSRange range = [string rangeOfString:#"null"];
//NSLog(#"in removeNull : %d >>>> %#",range.length, string);
if (range.length > 0 || string == nil) {
string = #"";
}
string = [self trimString:string];
return string;
}
And use this like bellow...
string = [self removeNull:string];
[string retain];
Bitlyzer *bitlyzer = [[Bitlyzer alloc] initWithDelegate:self];
[bitlyzer shortURL:string];
