Question

我有五个文本框，它们是子类视图，在触摸时循环来自数组的值。他们都是空白的开始。

如果框中收到@"\u2714"的值，我想用N / A自动填充其他框。

到目前为止，我尝试了什么，在收到@"\u2714"时更改了文本框值。不知道我在这里做错了什么？

这是我的nsarray：//self.valuesArray = [NSArray arrayWithObjects:@"\u2714", @"X", @"LIM", @"N/A", nil];

如果我将字符串设置为数组中的任何值，则文本框不会填充N / A.如果我将isEqualToString:sting设置为@""，我可以将我的文本框值全部默认为N / A，但不是基于循环播放数组时的任何输入

    self.tncsTapView.textValue = ([self attributeWithName:@"systemTypeTncs"]).value;
    if ([self.tncsTapView.textValue isEqualToString:@"X"]){
    self.tncTapView.textValue = @"N/A";
    self.tnsTapView.textValue = @"N/A";
    self.itTapView.textValue = @"N/A";
    self.ttTapView.textValue = @"N/A";
    }
    self.tnsTapView.textValue = ([self attributeWithName:@"systemTypeTns"]).value;
    if ([self.tnsTapView.textValue isEqualToString:@""]){

Answer 1

试试

self.tncsTapView.text = [self attributeWithName:@"systemTypeTncs"];

    if ([self.tncsTapView.text hasPrefix:@"\u2714"])
    {
    }

我想你必须在任何地方删除Value ...当你分配时，你将它指定为文本，同时检查你也检查它只是文本..

self.tncsTapView.text = [self attributeWithName:@"systemTypeTncs"];
if ([self.tncsTapView.text isEqualToString:@"\u2714"]){
self.tncTapView.text = @"N/A";
self.tnsTapView.text = @"N/A";
self.itTapView.text = @"N/A";
self.ttTapView.text = @"N/A";
}
self.tnsTapView.text = [self attributeWithName:@"systemTypeTns"];
if ([self.tnsTapView.text isEqualToString:@"\u2714"]){
self.tncsTapView.text = @"N/A";
self.tncTapView.text = @"N/A";
self.itTapView.text = @"N/A";
self.ttTapView.text = @"N/A";
}
self.tncTapView.text = [self attributeWithName:@"systemTypeTnc"];
if ([self.tncTapView.text isEqualToString:@"\u2714"]){
self.tncsTapView.text = @"N/A";
self.tnsTapView.text = @"N/A";
self.itTapView.text = @"N/A";
self.ttTapView.text = @"N/A";
}

self.itTapView.text = [self attributeWithName:@"systemTypeIt"];
if ([self.itTapView.text isEqualToString:@"\u2714"]){
self.tncTapView.text = @"N/A";
self.tnsTapView.text = @"N/A";
self.tncsTapView.text = @"N/A";
self.ttTapView.text = @"N/A";
}

self.ttTapView.text = [self attributeWithName:@"systemTypeTt"];
if ([self.ttTapView.text isEqualToString:@"\u2714"]){
self.ttTapView.text = @"N/A";
self.tnsTapView.text = @"N/A";
self.itTapView.text = @"N/A";
self.tncsTapView.text = @"N/A";
}

NSString中的反斜杠由两个连续的反斜杠表示。在所有if语句中，请尝试以下操作：

if ([self.tncsTapView.textValue isEqualToString:@"\\u2714"])

如果带有文本框的语句不起作用
