iPhone：dataUsingEncoding支持哪些不同类型的编码？

Question

任何人都可以指向我的任何文章或文档列出iPhone中的“dataUsingEncoding”支持的所有编码类型？

Answer 1

的NSString availableStringEncodings方法将返回可用的编码列表 - 电流（如的iOS 4.2的）选项的存在：

• NSASCIIStringEncoding
• NSUnicodeStringEncoding
• NSISOLatin1StringEncoding
• NSISOLatin2StringEncoding
• NSSymbolStringEncoding

Answer 2

[NSString的availableStringEncodings]

Answer 3

//This can print all of encoding that iPhone supports 
NSMutableArray *arrayOfEncodings = [[NSMutableArray alloc] init]; 

const NSStringEncoding *encodings = [NSString availableStringEncodings]; 
while (*encodings != 0){ 
    [arrayOfEncodings addObject:[NSNumber numberWithUnsignedLong:*encodings]]; 
    encodings++; 
} 

for (int i=0; i<arrayOfEncodings.count; i++) { 
    NSStringEncoding aNSStringEncoding = [[arrayOfEncodings objectAtIndex:i] unsignedLongValue]; 
    CFStringEncoding aCFStringEncoding = CFStringConvertNSStringEncodingToEncoding(aNSStringEncoding); 
    CFStringRef encodingNameInCFString = CFStringGetNameOfEncoding(aCFStringEncoding); 
    NSString * encodingName = (NSString*)encodingNameInCFString; 
    NSLog(@"%@", encodingName); 
}
