NSData& NSURL - 空间有问题的网址 [英] NSData & NSURL - url with space having problem

问题描述

我的应用程序中有以下代码。

I have following code in my application.

NSData *data=[NSData dataWithContentsOfURL:[NSURL URLWithString:pathOfThumbNail]];

pathOfThumbNail有以下路径

pathOfThumbNail has following path

http://70.84.58.40/projects/igolf/TipThumb/ GOLF 58B.jpg

当我在safari浏览器中打开上述路径时 - 路径自动更改&图像已成功显示。

When I open above path in safari browser - path is changed automatically & image is successfully displayed.

http://70.84.58.40/projects/igolf/TipThumb/GOLF%2058B.jpg

但在iPhone中，由于路径中的空间，图像未加载到nsdata中。

But in iPhone, due to space in path, image isn't loaded in nsdata.

推荐答案

使用：stringByAddingPercentEscapesUsingEncoding：

Use: stringByAddingPercentEscapesUsingEncoding:

使用给定的编码返回接收器的表示，以确定将接收器转换为合法URL字符串所需的转义百分比。

Returns a representation of the receiver using a given encoding to determine the percent escapes necessary to convert the receiver into a legal URL string.

-(NSString *)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

接收器的表示，使用编码来确定将接收器转换为合法URL字符串所需的转义百分比。如果编码不能编码特定字符，则返回nil

A representation of the receiver using encoding to determine the percent escapes necessary to convert the receiver into a legal URL string. Returns nil if encoding cannot encode a particular character

Added per request by @rule

NSString* urlText = @"70.84.58.40/projects/igolf/TipThumb/GOLF 58B.jpg";
NSString* urlTextEscaped = [urlText stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString: urlTextEscaped];
NSLog(@"urlText:        '%@'", urlText);
NSLog(@"urlTextEscaped: '%@'", urlTextEscaped);
NSLog(@"url:            '%@'", url);

NSLog输出：

urlText:        '70.84.58.40/projects/igolf/TipThumb/GOLF 58B.jpg'  
urlTextEscaped: '70.84.58.40/projects/igolf/TipThumb/GOLF%2058B.jpg'  
url:            '70.84.58.40/projects/igolf/TipThumb/GOLF%2058B.jpg'
