我有一个包含三个单词的字符串，由管道 ( | ) 分隔 我想将它们分成三个单独的字符串
NSArray *bits = [word.variants componentsSeparatedByString: @"|"];
NSLog(@"BITS: %@", bits);
这将返回一个无法识别的选择器。我在项目的其他区域使用了这行代码，并且运行良好。但不是这个。
-[__NSArrayI componentsSeparatedByString:]: unrecognized selector sent to instance 0x6dbfa80
有什么想法吗？
最佳答案
我也有同样的问题，而我的字符串有这么多白色字符、换行符，所以我无能为力，但最后我得到了如下解决方案:
NSString *artwork = [currentURL valueForKey:@"artwork_large"];
//i got the string artwork ,which is fetch from json.
[smg addObject:artwork];
// add this string to 0th index of an array name:smg
NSSet *setObj1 = [NSSet setWithArray:smg];
//make the nsset for my array (named :smg)
NSString *pictureName = [[setObj1 allObjects] componentsJoinedByString:@","];
//make the string from all the sets joined by ","
picArray = [pictureName componentsSeparatedByString:@","];
//now its time for normal operation means makes the array (name: picArray) from string by componenet separatedbystring method
这样我现在就得到了我们可以控制的完美数组
