在請求服務器時，如果參數(shù)中帶有中文字符。就會報參數(shù)格式錯誤，需要將其轉換成UTF8

?

@interface NSString (NSURLUtilities)

?

/* Adds all percent escapes necessary to convert the receiver into a legal URL string.? Uses the given encoding to determine the correct percent escapes (returning nil if the given encoding cannot encode a particular character).? See CFURLCreateStringByAddingPercentEscapes in CFURL.h for more complex transformations

?*/

- (NSString *)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)enc;

?

/* Replaces all percent escapes with the matching characters as determined by the given encoding.? Returns nil if the transformation is not possible (i.e. the percent escapes give a byte sequence not legal in the given encoding).? See CFURLCreateStringByReplacingPercentEscapes in CFURL.h for more complex transformations

?*/

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)enc;

?

@end

代碼如下：

? ? ? ? ? ? ? ??@"keyword": [searchSoft.text?stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
