Objective-C —文本字段到字符串数组

Question

I have this and it works:

[pole insertObject: [NSString stringWithFormat:@"%s",[textfield text]] atIndex:idpole];

But this doesn't save to string what is in the texfield, but some numbers or other unspecified characters. What can I do, to save real text from a textfield?

Answer 1

There is no need to create a new string:

[pole insertObject: [textfield text] atIndex:idpole];

Or if you want to make sure the the string a new object:

[pole insertObject: [NSString stringWithString:[textfield text]] atIndex:idpole];

Answer 2

尝试：

[pole insertObject:[textfield text] atIndex:idpole];

Answer 3

Thats because [textfield text] is a reference to a NSString object.

Answer 4

[pole insertObject: [NSString stringWithFormat:@"%@",[textfield text]] atIndex:idpole];

    NSlog(@"%@",pole);
