So my textfield has the following text. @"A big Tomato is red."
I want to get the word before "is".
When I type
NSString *someString = [[textfield componentsSeparatedByString:@"is"]objectAtIndex:0];
I always get "A big Tomato" instead of just "Tomato". In the app people will type things before "is" so I need to always get the string before "is". I would appreciate any help I can get. *Warning,
This is a very difficult problem.
Try this,
NSString *value = @"A big Tomato is red.";
NSArray *array = [value componentsSeparatedByString:@" "];
if ([array containsObject:@"is"]) {
NSInteger index = [array indexOfObject:@"is"];
if (index != 0) {
NSString *word = [array objectAtIndex:index - 1];
NSLog(@"%@", word);
}
}
Try this
NSString *string = @"A big Tomato is red.";
if ([string rangeOfString:@"is"].location == NSNotFound) {
NSLog(@"string does not contain is");
} else {
NSLog(@"string contains is!");
}
try this
NSString *str = @"A big tomato is red";
NSArray *arr = [str componentsSeparatedByString:@" "];
int index = [arr indexOfObject:@"is"];
if(index > 1)
NSString *str_tomato = arr[index-1];
else
//"is" is the first word of sentence
