I want to extract string between [ ] brackets
for Example Original string: @"this is a test [to get this string]."
I want to get extract string between [] ie "to get this string" in this example.
Please find below my code
NSMutableString *predicateString = [[NSMutableString alloc] initWithFormat:@"%@",@"this is a test [to get this string]."];
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"\[[^\].]*\]"
options:NSRegularExpressionCaseInsensitive
error:&error];
NSMutableArray *rangeArray = [[NSMutableArray alloc] init];
__block NSUInteger count = 0;
[regex enumerateMatchesInString:predicateString options:0 range:NSMakeRange(0, [predicateString length]) usingBlock:^(NSTextCheckingResult *match, NSMatchingFlags flags, BOOL *stop){
NSRange matchRange = [match range];
matchRange.length = matchRange.length+1;
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
NSLog(@"matchRange.location: %d",matchRange.location);
NSLog(@"matchRange.length: %d",matchRange.length);
if (++count >= 100) *stop = YES;
}];
Please let me know if I am doing something wrong.
Thanks.
看起来表达式是错误的,你需要转义斜杠(例如: @"\\\\[[^\\\\].]*\\\\]"
)。
