在XCode中替换字符 - Objective-C

Question

我已经使用此代码将"\n"替换为"",但它无效.

我该怎么做？

NSString *descString = [values objectForKey:@"description"];
descString = [descString stringByReplacingOccurrencesOfString:@"\n" withString:@""];

NSLog(@"Description String ---->>> %@",descString);
catlog.description = descString;
[webview loadHTMLString:catlog.description baseURL:nil];
webview.opaque = NO;

Answer 1

试试这个

NSString *s = @"foo/bar:baz.foo";
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"/:."];
s = [[s componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];
NSLog(@"%@", s);

Answer 2

descString = [descString stringByReplacingOccurrencesOfString:@"\\n" withString:@""];
