您只需使用

雨燕1

var str: String = "\"Hello\""

print(str) // "Hello"

print(str.stringByReplacingOccurrencesOfString("\"", withString: "")) // Hello

Swift 3和4的更新

print(str.replacingOccurrences(of: "\"", with: "")) // Hello

"\"Hello\"".stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "\""))

在斯威夫特3中：

let myString = "\"Hello\""
print(myString)  // "Hello"

let myNewString = myString.replacingOccurrences(of: "\"", with: "")
print(myNewString) // Hello

str.stringByReplacingOccurrencesOfString("\"", withString: "")

//这样尝试

var strString = "\"Hello\""

strString = strString.stringByReplacingOccurrencesOfString("\"", withString: "")

您可以使用\从字符串中删除引号
\”（双引号）
'（单引号）
例如：

NSString *s = @"your String";
NSCharacterSet *newStr = [NSCharacterSet characterSetWithCharactersInString:@"/""];
s = [[s componentsSeparatedByCharactersInSet: newStr] componentsJoinedByString: @""];
NSLog(@"%@", s);
