How can I get a substring between predefined strings. For example:
NSString* sentence = @"Here is my sentence. I am looking for {start}this{end} word";
NSString* start = @"{start}";
NSString* end = @"{end}";
NSString* myWord = [do some stuff with:sentence and:start and:end];
NSLog(@"myWord - %@",myWord);
Log: myWord - this
The following will give you the output you want:
NSString* sentence = @"Here is my sentence. I am looking for {start}this{end} word";
NSString* start = @"{start}";
NSString* end = @"{end}";
NSRange startRange = [sentence rangeOfString:start];
NSRange endRange = [sentence rangeOfString:end];
if (startRange.location != NSNotFound && endRange.location != NSNotFound) {
NSString *myWord = [sentence substringWithRange:NSMakeRange(startRange.location + startRange.length, endRange.location - startRange.location - startRange.length)];
NSLog(@"myWord - %@", myWord);
}
else {
NSLog(@"myWord not found");
}
You can use rangeOfString:to get the location of each of the markers. Then use subStringWithRange:to extract the string part you want.
NSRange startRange = [sentence rangeOfString:start];
NSRange endRange = [sentence end];
NSString myWord = [NSString subStringWithRange:NSMakeRange(startRange.location+startRange.length, endRange.location-startRange.location+startRange.length)];
All code typed in Safari and no error handling included!
NSRange startRange = [sentence rangeOfString:start];
NSRange endRange = [sentence rangeOfString:end];
int startLocation = startRange.location + startRange.length;
int lenght = endRange.location - startLocation;
NSString* myWord = [sentence substringWithRange:NSMakeRange(startLocation, lenght)];
rangeOfStringfunction.
