按字符串删除所有重音符号

Question

surnameField.text = "Fal à èà ò l'opo";    

// remove space and apostrophe
NSString *surnarmeInput = [[surnameField.text stringByReplacingOccurrencesOfString:@" " withString:@""] stringByReplacingOccurrencesOfString:@"'" withString:@""];

我也会删除重音符。

结果“Falaeaolopo”

Answer 1

// convert to a data object, using a lossy conversion to ASCII
NSData *asciiEncoded = [yourOriginalString dataUsingEncoding:NSASCIIStringEncoding
                         allowLossyConversion:YES];

// take the data object and recreate a string using the lossy conversion
NSString *other = [[NSString alloc] initWithData:asciiEncoded
                                        encoding:NSASCIIStringEncoding];
// relinquish ownership
[other autorelease];

将删除所有重音符号。删除所有空格

NSString *yourFinalString = [other stringByReplacingOccurrencesOfString:@" " withString:@""];

删除重音的第一部分，从this线程中的dreamlax的答案复制的代码..

Answer 2

使用dataUsingEncoding：allowLossyConversion：似乎不适用于某些字符 - 例如Đ和đ。我对这些进行了特定的检查，然后是ascii编码。

Answer 3

尝试使用NSString中的dataUsingEncoding:allowLossyConversion:方法。
