本文介绍了将由逗号分隔的NSString转换为NSArray的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个NSArray myArray数组,这里是内容:
I have an array of an NSArray myArray, here is the content:
(
"<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246",
"<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324",
"<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367"
)
我使用下面的代码分配给NSString myString:
I used the code below to assign to an NSString myString:
NSString *myString = [myArray description];
输出仍然如预期:
(
"<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246",
"<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324",
"<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367"
)
现在,我想将myString转换回数组名为newArray,我使用了这个:
Now, say I want to convert myString back to an array named newArray, I used this:
NSArray *newArray = [[NSArray alloc]init];
newArray = [myString componentsSeparatedByString:@","];
但是newArray的内容现在不同了:
But the content of the newArray is now different:
(
"(
\"<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246\"",
"
\"<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324\"",
"
\"<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367\""
)"
)
我知道我需要做些什么来解决这个问题?
Any idea what I need to do to fix this?
推荐答案
有两种方法
- - (NSArray *)componentsSeparatedByString :(NSString *)分隔符
- - (NSString *)componentsJoinedByString:(NSString *)separator
- - (NSArray *)componentsSeparatedByString:(NSString *)separator
- - (NSString *)componentsJoinedByString:(NSString *)separator
使用
NSString *myString = [myArray componentsJoinedByString:@","]; //instead of [myArray description];
