Closed 5 years ago.
My string text is Like -
1) .....bla ..bla...
2)...bla.. bla…bla.
3).bla.. bla…bla.
dots are not static.I want to remove dots only from starting. not All dots
I have tried with this
NSString *newString = [myString stringByReplacingOccurrencesOfString:#"." withString:#""];
but this is removing all dots.

Answer 1

try this.
NSString* regex = #"^\\.*";
NSString* input = #"....abc..z";
NSString* output = [input stringByReplacingOccurrencesOfString:regex withString:#"" options:NSRegularExpressionSearch range: [input rangeOfString:input]];

Answer 2

var test = "...abc";
while test.hasPrefix(".") {
test.remove(at: test.startIndex)
}
//test variable will have dots removed at the start.
Try this.

Answer 3

Try this:
NSString *str = #"...Videt...IDL";
__block NSInteger loc = 0;
[str enumerateSubstringsInRange:NSMakeRange(0, str.length) options:NSStringEnumerationByWords usingBlock:^(NSString * _Nullable substring, NSRange substringRange, NSRange enclosingRange, BOOL * _Nonnull stop) {
loc = substringRange.location;
*stop = YES;
}];
NSString *convStr = [str substringFromIndex:loc];
NSLog(#"%#", convStr);

Answer 4

NSString *str = #"....bla .... bla..... bla";
NSCharacterSet *charSet = [NSCharacterSet letterCharacterSet];
int letterNO = 0;
for (int i =0; i<str.length; i++)
{
NSString *letter = [NSString stringWithFormat:#"%c",[str characterAtIndex:i]];
if ([letter rangeOfCharacterFromSet:charSet].location != NSNotFound)
{
letterNO = i;
break;
}
}
NSString * newString = [str substringFromIndex:letterNO];
NSLog(#"newString %#",newString);
