无法将文本从UITextField添加到数组 [英] Unable to add text from UITextField to an Array
问题描述
当前,我在其上方有一个自定义视图表格单元格和一个文本字段。我想从 UItextfield
获取文本,并将其放入 NSMutableArray
中。
Currently I have a custom view table cell and a text field just above it. I want to get the text from the UItextfield
and put that into an NSMutableArray
.
伪代码:
String text = _textfield.text;
[array addObject:text];
NSLog{array}
在我的头文件中,我创建了文本字段和数组。
In my header file I have created the textfield and the array.
我目前收到错误:'CustomTableView:[340:11303] array:(null)'
NSLog。
I currently receive the error : 'CustomTableView:[340:11303] array: (null)'
when I NSLog.
我不确定为什么文本字段中的文本没有被添加到数组中。如果有人能够提供帮助,将不胜感激。
I am not to sure why the text from the textfield is not getting added to the array. If any one is able to help it will be greatly appreciated.
注意-我的文本字段位于自定义单元格上方,不在其中。我什至尝试将字符串直接直接添加到数组中并记录下来,但我得到了相同的错误。因此,我认为这与数组有关。
Note - My textfield is above the custom cell not in it. I have even tried just adding a string to the array directly and logging it and I get the same error. So I would assume that this is something to do with the array.
推荐答案
您初始化了Array。采用MutableArray并将其初始化。
did you initialize your Array.take a MutableArray and initialize it.
NSMutableArray *array=[NSMutableArray alloc]init];
