文件，文件夹问题
IOS 获取 Document 文件夹路径
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath2 = [documentsDirectory stringByAppendingPathComponent:@"Screenshot.png"];
IOS调取摄像头并拍照
<UIImagePickerControllerDelegate>
1、打开摄像头
- (IBAction)Open:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
NSArray *temp_MediaTypes = [UIImagePickerControlleravailableMediaTypesForSourceType:picker.sourceType];
picker.mediaTypes = temp_MediaTypes;
picker.delegate = self;
picker.allowsImageEditing = YES;
}
[self presentModalViewController:picker animated:YES];
[picker release];
}
2.拍照回调
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
if ([mediaType isEqualToString:@"public.image"]){
UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"];
NSLog(@"found an image");
NSString *imageFile = [documentsDirectory stringByAppendingPathComponent:@"temp.jpg"];
NSLog(@"%@", imageFile);
success = [fileManager fileExistsAtPath:imageFile];
if(success) {
success = [fileManager removeItemAtPath:imageFile error:&error];
}
imageView.image = image;
[UIImageJPEGRepresentation(image, 1.0f) writeToFile:imageFile atomically:YES];
//SETIMAGE(image);
//CFShow([[NSFileManager defaultManager] directoryContentsAtPath:[NSHomeDirectory() stringByAppendingString:@"/Documents"]]);
}
else if([mediaType isEqualToString:@"public.movie"]){
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(@"%@", videoURL);
NSLog(@"found a video");
NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
NSString *videoFile = [documentsDirectory stringByAppendingPathComponent:@"temp.mov"];
NSLog(@"%@", videoFile);
success = [fileManager fileExistsAtPath:videoFile];
if(success) {
success = [fileManager removeItemAtPath:videoFile error:&error];
}
[videoData writeToFile:videoFile atomically:YES];
//CFShow([[NSFileManager defaultManager] directoryContentsAtPath:[NSHomeDirectory() stringByAppendingString:@"/Documents"]]);
//NSLog(videoURL);
}
[picker dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
}
IOS下载文件（同步下载）
NSString *urlAsString = @"http://files.cnblogs.com/zhuqil/UIWebViewDemo.zip";
NSURL *url = [NSURL URLWithString:urlAsString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSError *error = nil;
NSData* data= [NSURLConnection sendSynchronousRequest:request returningResponse:nilerror:&error];
/* 下载的数据 */
if (data != nil){
NSLog(@"下载成功");
if ([data writeToFile:@"/Users/jilucky/UIWebViewDemo.zip" atomically:YES]) {
NSLog(@"保存成功.");
}
else
{
NSLog(@"保存失败.");
}
} else {
NSLog(@"%@", error);
}
IOS震动效果
AudioToolBox.framework
#import "AudioToolbox/AudioToolbox.h"
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
IOS获取设备号
UIDevice *device = [UIDevice currentDevice];//创建设备对象
NSString *deviceUID = [[NSString alloc] initWithString:[device uniqueIdentifier]];
UIAlertView *view = [[UIAlertView alloc]initWithTitle:nil message:deviceUID delegate:selfcancelButtonTitle:@"ok" otherButtonTitles: nil];
[view show];
Unity 3D截屏
1.js脚本（添加到ARCamera上）
#pragma strict
function Start () {}
function Update () {}
function ScreenImage(){
Application.CaptureScreenshot("Scr
补充：移动开发 , IOS ,
