Question

我有一个字符串："mocktail, wine, beer"

如何将其转换为："mocktail", "wine", "beer"？

Answer 1

以下内容为您提供了所需的结果：

NSString *_inputString = @"\"mocktail, wine, beer\"";
NSLog(@"input string : %@", _inputString);
NSLog(@"output string : %@", [_inputString stringByReplacingOccurrencesOfString:@", " withString:@"\", \""]);

结果是：

input string : "mocktail, wine, beer"
output string : "mocktail", "wine", "beer"

Answer 2

您需要使用：

NSArray * components = [myString componentsSeparatedByString: @", "];

Answer 3

NSString *string = @"mocktail, wine, beer";
//remove whitespaces
NSString *trimmedString = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

//get array of string
NSArray *array = [trimmedString componentsSeparatedByString:@","];
NSMutableArray *newArray = [[NSMutableArray alloc] init];

for (NSString *trimmedString in array) {
    NSString *newString = [NSMutableString stringWithFormat:@"'%@'", trimmedString];
    [newArray addObject:newString];
}

//merge new strings
NSString *finalString = [NSString stringWithFormat:@"%@", [newArray objectAtIndex:0]];

for (NSInteger i = 1; i < [newArray count]; i++) {
        finalString = [NSString stringWithFormat:@"%@, %@", finalString, [newArray objectAtIndex:i]];
}

Answer 4

如果不清楚地了解iOS或objective-c，我假设您可以使用拆分功能。

在几乎任何更高级别的编程语言中都有这样的功能。

尝试： Objective-C split

这会为您提供一系列字符串。然后，您可以实际处理您想要做的事情，例如：用单引号包围它们并将它们重新附加在一起。：d

将String转换为特殊 - 拆分NSString
