空格NSURL连接
空格NSURL连接

我正在尝试有一个名字字段，人们可以把名字放在那里，它将发送到一个php页面。
我已经在没有空格的情况下用这段代码工作了。
- (IBAction)Submit:(id)sender {
NSString *strURL=[NSString stringWithFormat:@"http://www.bigwavemedia.co.uk/ios/contact.php?name=%@", nameField.text];
NSURL *url=[NSURL URLWithString:strURL];
self.request=[NSURLRequest requestWithURL:url];
self.nsCon=[[NSURLConnection alloc] initWithRequest:self.request delegate:self];
NSLog(@"out put = %@", self.request);
}但一旦我使用空格加法器修复，它就不会被我的php页面拾取，埃文，尽管日志说它是工作的。
- (IBAction)Submit:(id)sender {
NSString *strURL=[NSString stringWithFormat:@"http://www.bigwavemedia.co.uk/ios/contact.php?name=", nameField.text];
strURL = [strURL stringByAppendingString:nameField.text];
strURL = [strURL stringByAppendingString:@"'"];
strURL = [strURL stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
NSURL *url=[NSURL URLWithString:strURL];
self.request=[NSURLRequest requestWithURL:url];
self.nsCon=[[NSURLConnection alloc] initWithRequest:self.request delegate:self];
NSLog(@"out put = %@", self.request);
}我是不是遇到了语法错误，或者以错误的方式处理此方法？
我的.h文件
#import <UIKit/UIKit.h>
@interface ContactViewController : UIViewController <UITextFieldDelegate, UITextViewDelegate, NSURLConnectionDataDelegate>{
IBOutlet UITextField *nameField;
}
- (IBAction)Submit:(id)sender;
@property (nonatomic, retain) IBOutlet UITextField *nameField;
@property (strong) NSURLConnection *nsCon;
@property (strong) NSURLConnection *request;
@property (strong) NSURLConnection *receivedData;
@end谢谢

在发出请求之前，您需要使用stringByAddingPercentEscapesUsingEncoding。
NSURL *url = [NSURL URLWithString:
[[str stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];对于您的代码，请尝试以下代码。
- (IBAction)Submit:(id)sender {
NSString *strURL=[NSString stringWithFormat:@"http://www.bigwavemedia.co.uk/ios/contact.php?name=%@", nameField.text];
NSURL *url = [NSURL URLWithString:
[[strURL stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];
self.request=[NSURLRequest requestWithURL:url];
self.nsCon=[[NSURLConnection alloc] initWithRequest:self.request delegate:self];
NSLog(@"out put = %@", self.request);
