objective c - need one methods to quantities replace for NSMutableAttributedString same as stringByReplacingOccurrencesOfString for NSString? -

is there replace method nsmutableattributedstring similar stringbyreplacingoccurrencesofstring: nsstring?

nsstring *newstring = [mystring stringbyreplacingoccurrencesofstring:@"," withstring:@""]; 

i need same method nsmutableattributedstring. (i need replace string image).

nsmutableattributedstring *mutableattstring = [[nsmutableattributedstring alloc] init];  nstextattachment *attachment = [[nstextattachment alloc] init];      attachment.image = [uiimage imagenamed:@"a.png"];  nsattributedstring *attachmentstring = [nsattributedstring attributedstringwithattachment:attachment];   [mutableattstring replacecharactersinrange:getanswer                            withattributedstring:attachmentstring]; 

this way replace 1 time. need quantities replace

replacecharactersinrange:withattributedstring: correct method use, need find range want replace first.

to that, use string method of attributed string , 1 of rangeof... methods find appropriate range want replace.

also, example shows calling [[nsmutableattributedstring alloc] init] , replacecharactersinrange:withattributedstring:, should have in mutable string before try replace it.
