Iphone 如何删除UIAlertView中的括号

我正在使用这个代码

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Call Forward Enabled" 
    message:[NSString stringWithFormat:@"All calls to %@ are now forwarded to voicemail.\n Condition:\n %@ ",selected_phone_numbe ,selectedOption] 
    delegate:self cancelButtonTitle:@"Ok" 
    otherButtonTitles:nil, nil];

---

我认为

selected\u phone\u number&selectedOption

附带该括号，将其移除，然后在警报中使用

NSCharacterSet *charsToTrim = [NSCharacterSet characterSetWithCharactersInString:@"()"];
s = [s stringByTrimmingCharactersInSet:charsToTrim];

---

selected\u phone\u number

和

selectedOption

看起来要么是数组，要么是字符串本身包含（和）

检查类类型（类内省）。如果是数组，请使用数组[0]

---

如果是字符串，则可以用空字符串替换

（

&

）

。

在显示警报之前，可以放置此代码，您可以一次替换所有不需要的字符

 NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"()"];// declare set of unwanted charecters here.

selected_phone_numbe = [[selected_phone_numbe componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];

selectedOption = [[selectedOption componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];

输出：

请尝试使用这个。我希望它能帮助你

NSString *msgStr = [NSString stringWithFormat:@"All calls to %@ are now forwarded to voicemail.\n Condition:\n %@ ",selected_phone_numbe ,selectedOption]

     msgStr =  [msgStr stringByReplacingOccurrencesOfString:@"(" withString:@""];
     msgStr = [msgStr stringByReplacingOccurrencesOfString:@")" withString:@""];

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Call Forward Enabled" 
    message:msgStr  delegate:self cancelButtonTitle:@"Ok" 
    otherButtonTitles:nil, nil];

试试这个：

NSString * changeString =  [NSString stringWithFormat:@"All calls to %@ are now forwarded to voicemail.\n Condition:\n %@ ",[[selected_phone_numbe stringByReplacingOccurrencesOfString:@"(" withString:@""] stringByReplacingOccurrencesOfString:@")" withString:@""] ,[[selectedOption stringByReplacingOccurrencesOfString:@"(" withString:@""] stringByReplacingOccurrencesOfString:@")" withString:@""]];
    UIAlertView *callAlert = [[UIAlertView alloc] initWithTitle:@"Call Forward Enabled"
                                                        message:changeString
                                                       delegate:self cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil, nil];
    [callAlert show];

并检查此方法：

-(NSString *)replacingString:(NSString*)mainString removeString:(NSString *)rmString withReplace:(NSString*)rpString{
    mainString = [mainString stringByReplacingOccurrencesOfString:rmString withString:rpString];

    return mainString;

}

你得到了你的答案

谢谢：）

-(NSString *)replacingString:(NSString*)mainString removeString:(NSString *)rmString withReplace:(NSString*)rpString{
    mainString = [mainString stringByReplacingOccurrencesOfString:rmString withString:rpString];

    return mainString;

}
