NSString - 如何从“ÁlgeBra”到“代数” [英] NSString - how to go from "ÁlgeBra" to "Algebra"

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 capitalizedString ：

接收器中每个字词的第一个字符的字符串更改为其对应的大写字母值，所有其余字符均设置为其对应的小写字母值。

  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]; 
  

dataUsingEncoding：allowLossyConversion： 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:

Return Value

A string with the first character from each word in the receiver changed to its corresponding uppercase value, and all remaining characters set to their corresponding lowercase values.

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.
