nsstring stringByReplacingOccurrencesOfString frustration?
提问by BlockReader
I am trying to replace/remove this:
我正在尝试替换/删除这个：
[\"
[\"
from string bump3
从字符串bump3
NSString *bump5 = [bump3 stringByReplacingOccurrencesOfString:@"[\"" withString:@""];
ERROR: missing terminating "" character.
错误：缺少终止的“”字符。
could someone please help me out? My brain is so fried from staring at this screen..
有人可以帮我吗？盯着这个屏幕我的脑子都炸了。。
UPDATE:
更新：
Figured it out by chance and tried it out!
偶然发现并尝试了它！
@"\" is a single backslash @"\\" is a double backslash
@"\" 是单反斜杠 @"\\" 是双反斜杠
so I used NSString *bump5 = [bump3 stringByReplacingOccurrencesOfString:@"[\\"" withString:@""];
所以我使用 NSString *bump5 = [bump3 stringByReplacingOccurrencesOfString:@"[\\"" withString:@""];

You should escape both \and "
你应该同时逃避\和"
NSString *bump5 = [bump3 stringByReplacingOccurrencesOfString:@"[\\"" withString:@""];

Try this to remove a "-" from a string. for example a chain 2773848-2294-2929
试试这个从字符串中删除“-”。例如链 2773848-2294-2929
string = 2773848-2294-2929;
NSString * replace = [string stringByReplacingOccurrencesOfString: @ "-" withString: @ ""];
The result will return the following string: 277384822942929
结果将返回以下字符串：277384822942929
