1.iOS9新特性：Bitcode
当运行之前的项目报错时，我们可以在”Build Settings”->”Enable Bitcode”中设置属性为NO
2.获取设备名字
[Device machineName]
3.获取沙盒Documents路径
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0];
4.发短信方法
4.1openURL
[[UIApplication sharedApplication] openURL:@"sms:12345678"];
4.2MFMessageComposeViewController
首先在程序中导入MessageUI.framework。import头文件：#import "DeviceDetection.h"
然后在代码中使用下面的语句来调用短信发送窗口，并指定号码和短信内容：
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init]; controller.title = @"短信房源"; controller.body = HouseInfo; controller.recipients = nil; controller.messageComposeDelegate = self; [self presentViewController:controller animated:YES completion:nil];
5.复制内容到剪切板
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; pasteboard.string = ResponseObj;
6。iOS字符创中去除特殊字符串
NSInteger leftLength=[[leftStr stringByTrimmingCharactersInSet:[NSCharacterSet decimalDigitCharacterSet]] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]].length;
7.NSCharacterSet 简单用法
NSMutableCharacterSet *base = [NSMutableCharacterSet lowercaseLetterCharacterSet]; //字母
NSCharacterSet *decimalDigit = [NSCharacterSet decimalDigitCharacterSet]; //十进制数字
[base formUnionWithCharacterSet:decimalDigit]; //字母加十进制
NSString *string = @"[email protected]#@sfn$5`SF$$%x^(#e{]e";
//用上面的base隔开string然后组成一个数组，然后通过componentsJoinedByString，来连接成一个字符串
NSLog(@"%@",[[string componentsSeparatedByCharactersInSet:base] componentsJoinedByString:@"-"]);
[base invert]; //非 字母加十进制
NSLog(@"%@",[[string componentsSeparatedByCharactersInSet:base] componentsJoinedByString:@"-"]);
答应结果：
[email protected]-s#@sfn$-`SF$$%x^(#e{]e

8.从系统选择多张图片
先导入库ELCImagePicker（第三方）
//从照片库
if ([self shouldImage])
{
ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];
elcPicker.maximumImagesCount = 16-[images_ numberOfPhotos];
elcPicker.returnsOriginalImage = NO;
elcPicker.imagePickerDelegate = self;
[self presentViewController:elcPicker animated:YES completion:nil];
}else
{
UIAlertView *al=[[UIAlertView alloc]initWithTitle:@"权限受限" message:@"设置-手机梵讯-隐私" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];
[al show];
}
#pragma mark ELCImagePickerController delegate
-(void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info
{

{

//需要准备的数据

[self houseimageNumber:nil];
}
if (isSuccess)
{
[ProgressHUD showSuccess:@"添加成功"];
[picker dismissViewControllerAnimated:YES completion:nil];
[self reloadSubviews];
}
}
-(void)elcImagePickerControllerDidCancel:(ELCImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

}
}
}
-(void)image:(UIImage*)image didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo{

{

}
else
{
NSLog(@"错误提示%@", error);
}
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:nil];
}
9.判断是否支持拍照和相册
-(BOOL)shouldPhoto
{
BOOL agree=NO;
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
if(authStatus == AVAuthorizationStatusAuthorized||authStatus == AVAuthorizationStatusNotDetermined)
{
agree=YES;
}else
{
agree=NO;
}
return agree;
}
-(BOOL)shouldImage
{
BOOL agree=NO;
ALAuthorizationStatus author = [ALAssetsLibrary authorizationStatus];
if(author == ALAuthorizationStatusAuthorized||author == ALAuthorizationStatusNotDetermined)
{
agree=YES;
}else
{
agree=NO;
}
return agree;
}
10.上传图片
+(void)httpUploadHeadImage:(NSString *)Actio WithParam:(NSDictionary *)param success:(void(^)(id ResponseObject))Success Failure:(void (^)(id ResponseObject))Failure
{
NSMutableDictionary *mDict = [NSMutableDictionary dictionary];
if (param!=nil)
{
[mDict setDictionary:param];
}
AFHTTPRequestOperationManager * manager =[AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:Actio parameters:NULL constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
[formData appendPartWithFormData:[[NSString stringWithString:[mDict objectForKey:@"PKUser"]] dataUsingEncoding:NSUTF8StringEncoding] name:@"PKUser"];
[formData appendPartWithFormData:[[NSString stringWithString:[mDict objectForKey:@"relPath"]] dataUsingEncoding:NSUTF8StringEncoding] name:@"relPath"];
NSData * data=[NSData dataWithContentsOfFile:[mDict objectForKey:@"HeadBig"]];
[formData appendPartWithFileData:data name:@"big" fileName:[mDict objectForKey:@"HadebigName"] mimeType: @"Image/jpep"];
NSData * data1=[NSData dataWithContentsOfFile:[mDict objectForKey:@"Headsmall"]];
[formData appendPartWithFileData:data1 name:@"small" fileName:[mDict objectForKey:@"HadesmallName"] mimeType: @"Image/png"];
} success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSData * responseData = responseObject;
NSString * responseStr = [[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
Success(responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
}];
}
