NSString - 如何从“ÁlgeBra”到“代数”

问题描述

有没有人知道锄头会得到一个像ÁlgeBra到代数的NSString，没有重音，并只大写首字母？

解决方案

NSString 有一个名为：

  NSString * str = @AlgeBra 
 NSString * other = [str capitalizedString]; 
 
 NSLog（@Old：％@，New：％@，str，other）; 
  

编辑：

也想删除重音。您可以通过一系列步骤：

  //原始字符串
 NSString * str = @ÁlgeBra 
 
 //转换为数据对象，使用有损的转换为ASCII 
 NSData * asciiEncoded = [str dataUsingEncoding：NSASCIIStringEncoding 
 allowLossyConversion：YES]; 
 
 //获取数据对象并使用有损转换重建一个字符串
 NSString * other = [[NSString alloc] initWithData：asciiEncoded 
 encoding：NSASCIIStringEncoding]; 
 //放弃所有权
 [其他autorelease]; 
 
 //创建最终大写字符串
 NSString * final = [other capitalizedString]; 
  

明确表示，信件‘Á&rsquo ;将转换为‘ A’当转换为ASCII。

Does anyone knows hoe to get a NSString like "ÁlgeBra" to "Algebra", without the accent, and capitalize only the first letter?

Thanks,

解决方案

NSString has a method called capitalizedString:

NSString *str = @"AlgeBra";
NSString *other = [str capitalizedString];

NSLog (@"Old: %@, New: %@", str, other);

Edit:

Just saw that you would like to remove accents as well. You can go through a series of steps:

// original string
NSString *str = @"ÁlgeBra";

// convert to a data object, using a lossy conversion to ASCII
NSData *asciiEncoded = [str 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];

// create final capitalized string
NSString *final = [other capitalizedString];

The documentation for dataUsingEncoding:allowLossyConversion: explicitly says that the letter ‘Á’ will convert to ‘A’ when converting to ASCII.
