实用代码
1.将UIView设置成圆角的矩形需要加QuartzCore.framework
m_mainImgView.layer.cornerRadius = 6;m_mainImgView.layer.masksToBounds = YES;
2.segment要添加图片
[mapType_SegmentedControl insertSegmentWithImage:[UIImage imageNamed:@"d_cn_32.png"] atIndex:0 animated:YES];
[mapType_SegmentedControl insertSegmentWithImage:[UIImage imageNamed:@"w_cn_32.png"] atIndex:1 animated:YES];
[mapType_SegmentedControl insertSegmentWithImage:[UIImage imageNamed:@"r_cn_32.png"] atIndex:2 animated:YES];
3.上传图片
//上传到服务器
//分界线的标识符
NSString *TWITTERFON_FORM_BOUNDARY = @"AaB03x";
//根据url初始化request
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",web_site]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSLog(@"url:%@",url);
//分界线 --AaB03x
NSString *MPboundary=[[NSString alloc]initWithFormat:@"--%@",TWITTERFON_FORM_BOUNDARY];
//结束符 AaB03x--
NSString *endMPboundary=[[NSString alloc]initWithFormat:@"%@--",MPboundary];
//得到图片的data
NSLog(@"daxiao:%dKB",[UIImageJPEGRepresentation(image, 0.1) length]/1024);
NSData* data = UIImageJPEGRepresentation(image, 0.1);
//http body的字符串
NSMutableString *body=[[NSMutableString alloc]init];
NSString *message = [NSString stringWithFormat:@"%@\r\n",[dict JSONRepresentation]];
NSMutableDictionary *dictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:message,@"message",nil];
NSArray *keys = [dictionary allKeys];
for (int j=0; j<[keys count]; j++) {
NSString *key =[keys objectAtIndex:j];
//添加分界线，换行
[body appendFormat:@"%@\r\n",MPboundary];
//添加字段名称，换2行
[body appendFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n",key];
//添加字段的值
[body appendFormat:@"%@\r\n",[dictionary objectForKey:key]];
}
[body appendFormat:@"%@\r\n",MPboundary];
//添加字段名称，换2行
[body appendFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"image.PNG\"\r\n"];
////添加分界线，换行
[body appendFormat:@"%@\r\n",MPboundary];
//声明上传文件的格式
[body appendFormat:@"Content-Type: image/PNG\r\n\r\n"];
//声明结束符：--AaB03x--
NSString *end=[[NSString alloc]initWithFormat:@"\r\n%@",endMPboundary];
//声明myRequestData，用来放入http body
NSMutableData *myRequestData=[NSMutableData data];
//将body字符串转化为UTF8格式的二进制
[myRequestData appendData:[body dataUsingEncoding:NSUTF8StringEncoding]];
//将image的data加入
[myRequestData appendData:data];
//加入结束符--AaB03x--
[myRequestData appendData:[end dataUsingEncoding:NSUTF8StringEncoding]];
//设置HTTPHeader中Content-Type的值
NSString *content=[[NSString alloc]initWithFormat:@"multipart/form-data; boundary=%@",TWITTERFON_FORM_BOUNDARY,nil];
//设置HTTPHeader
[request setValue:content forHTTPHeaderField:@"Content-Type"];
//设置Content-Length
[request setValue:[NSString stringWithFormat:@"%d", [myRequestData length]] forHTTPHeaderField:@"Content-Length"];
//http method
[request setHTTPMethod:@"POST"];
[request setHTTPBody:myRequestData];
//建立连接，设置代理
NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request delegate:self];
[self.connections addObject:[NSDictionary dictionaryWithObjectsAndKeys:connection,@"connection",[dict objectForKey:@"MessageID"],@"assId", nil]];
4.计算2点之间距离
CLLocation* orig=[[[CLLocation alloc] initWithLatitude:** longitude:**] autorelease];
CLLocation* dist=[[[CLLocation alloc] initWithLatitude:** longitude:** ] autorelease];
俩点间的距离=[orig distanceFromLocation:dist];
这个算出来的是俩点间的直线距离。偏差50米左右
5.字符串过滤
NSString *str = @"一个 （ABC） ＃＠!＃^＃G＠＃Dd21e12d!E＠!212s012yhsn 汉0932字＃＠!中..文//>？输~~~＠＃￥＃＠％＃^＃^％&^*&（*）入";
NSMutableCharacterSet *set = [[NSMutableCharacterSet alloc] init];
[set formUnionWithCharacterSet:[NSCharacterSet lowercaseLetterCharacterSet]];//小写字母
NSLog(@"1 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet uppercaseLetterCharacterSet]];//大写字母
NSLog(@"2 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet symbolCharacterSet]];//符号
NSLog(@"3 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet punctuationCharacterSet]];//标点
NSLog(@"4 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet controlCharacterSet]];//把握符
NSLog(@"5 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet decimalDigitCharacterSet]];//小数
NSLog(@"6 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet letterCharacterSet]];//文字
NSLog(@"7 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet nonBaseCharacterSet]];//非根蒂根基
NSLog(@"8 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet alphanumericCharacterSet]];//字母数字
NSLog(@"9 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet decomposableCharacterSet]];//可分化
NSLog(@"10 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet illegalCharacterSet]];//不法
NSLog(@"11 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet capitalizedLetterCharacterSet]];//大写
NSLog(@"12 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet newlineCharacterSet]];//换行符
NSLog(@"13 %@",[str stringByTrimmingCharactersInSet:set]);
[set formUnionWithCharacterSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];//空格换行
NSLog(@"14 %@",[str stringByTrimmingCharactersInSet:set]);
6.字符串操作
1.截取字符串
NSString*string =@"sdfsfsfsAdfsdf";
string = [string substringToIndex:7];//截取下标7之后的字符串
NSLog(@"截取的值为：%@",string);
[string substringFromIndex:2];//截取下标2之前的字符串
NSLog(@"截取的值为：%@",string);
2.匹配字符串
NSString*string =@"sdfsfsfsAdfsdf";
NSRangerange = [stringrangeOfString:@"f"];//匹配得到的下标
NSLog(@"rang:%@",NSStringFromRange(range));
string = [string substringWithRange:range];//截取范围类的字符串
NSLog(@"截取的值为：%@",string);
3.分隔字符串
NSString*string =@"sdfsfsfsAdfsdf";
NSArray *array = [string componentsSeparatedByString:@"A"]; //从字符A中分隔成2个元素的数组
NSLog(@"array:%@",array); //结果是adfsfsfs和dfsdf
// 触摸背景，关闭键盘
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [touches anyObject];
UIView *view = (UIView *)[touch view];
if (view == self.scrollView) {
[self.txtViewContent resignFirstResponder];
[self.txtTel resignFirstResponder];
[self.txtContact resignFirstResponder];
}
}
或者是
在.h文件中，添加 - ( IBAction)backgroundTap:( id)sender;
在.m中，添加
- (IBAction)backgroundTap:(id)sender{
[self.txtTele resignFirstResponder];
[self.txtPerson resignFirstResponder];
[self.txtViewContent resignFirstResponder];
}
然后将View的class改为UIControl，如图
最后连接Control的Touch Down事件
修改navigation的push动画
导入QuartzCore/QuartzCore.h
CATransition *transition = [CATransition animation];
transition.duration = 1;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = @"cube";
transition.subtype = kCATransitionFromTop;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController pushViewController:sub2 animated:NO];
