Shareing Example
NSString *shareString = @"CapTech is a great place to work."; UIImage *shareImage = [UIImage imageNamed:@"Icon.png"]; NSURL *shareUrl = [NSURL URLWithString:@"http://www.captechconsulting.com"]; NSArray *activityItems = [NSArray arrayWithObjects:shareString, shareImage, shareUrl, nil]; UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil]; activityViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentViewController:activityViewController animated:YES completion:nil]; [activityViewController setCompletionHandler:^(NSString *activityType, BOOL completed) { NSLog(@"Activity is %@", activityType); NSLog(@"Completed Status = %d", completed); if (completed) { } else { } }];

SLComposeViewController

參考1
參考2
參考中文網站

首先先加入Social.framework跟Accounts.framework

有三種可以使用

SLServiceTypeTwitter;
SLServiceTypeFacebook;
SLServiceTypeSinaWeibo;

分享facebook

SLComposeViewController *fbController=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) { SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){ [fbController dismissViewControllerAnimated:YES completion:nil]; switch(result){ case SLComposeViewControllerResultCancelled: default: { NSLog(@"Cancelled....."); } break; case SLComposeViewControllerResultDone: { NSLog(@"Posted...."); } break; }}; [fbController addImage:[UIImage imageNamed:@"1.jpg"]]; [fbController setInitialText:@"Check out this article."]; [fbController addURL:[NSURL URLWithString:@"http://soulwithmobiletechnology.blogspot.com/"]]; [fbController setCompletionHandler:completionHandler]; [self presentViewController:fbController animated:YES completion:nil]; }

Custom Fonts

參考網站

在專案裡面需要用到ttf的字型
所以記錄一下

加入the .ttf檔案到專案裡



確定Add to targets是勾起來的



點選.ttf檔確定右手邊的Target Memvership是打勾的



在回專案的TARGETS->Build Phases->Copy Bundle Resources



最後在專案的info.plist增加Fonts provided by application並加上.ttf的檔案名稱



然後取得.ttf的全名



使用方法
NSLog(@"vagrounded-bold.ttf is %@", [UIFont fontNamesForFamilyName:@"VAGRounded-Bold"] ); NSLog(@"vagrounded-thin.ttf is %@", [UIFont fontNamesForFamilyName:@"VAGROUNDED-Thin"] ); UILabel *lab = [UILabel new]; [lab setFrame:CGRectMake(50, 50, 100, 30)]; UIFont *swissLight = [UIFont fontWithName:@"VAGRounded-Bold" size:20.0f]; [lab setFont:swissLight]; [lab setText:@"GodCam"]; [self.view addSubview:lab]; UILabel *lab2 = [UILabel new]; [lab2 setFrame:CGRectMake(50, 100, 100, 30)]; UIFont *swissLight2 = [UIFont fontWithName:@"VAGROUNDED-Thin" size:20.0f]; [lab2 setFont:swissLight2]; [lab2 setText:@"GodCam"]; [self.view addSubview:lab2]; 2013-04-17 13:48:20.635 UseTTF[787:c07] vagrounded-bold.ttf is ( "VAGRounded-Bold" ) 2013-04-17 13:48:20.636 UseTTF[787:c07] vagrounded-thin.ttf is ( "VAGROUNDED-Thin" )

objective-c type

今天在查objective-c的資料形態
發現一個網站介紹的很仔細
參考網站
主要是為了要查long long怎麼format
我個人只有用過每個format的第一種方法
另外id的format我是都用%@

iphone5 launch image

現在的專案都要支援iphone5
所以忽然不知道怎麼加入iphone5 launch image
上網查了一下很簡單
只要把圖取名為Default-568h@2x.png
這樣就可以了

UIImageView zoom

專案裡需要一個小功能
針對圖片放大縮小

花了點時間找了些資料
實作的時候卻發現在zoom的時候圖片怪怪的
原來魔鬼藏在細節裡
大致上最重要的一句話就是

//如果不加这句的话
[imageView setFrame:CGRectMake(0, 0, scrollView.frame.size.width, scrollView.frame.size.height)];
//那么正常拖动是可以的，但是如果zoom了 就会有问题

全整的程式碼
scrollViewController.h
記得加上UIScrollViewDelegate
這樣才有拖拉放大縮小的效果
#import @interface scrollViewController : UIViewController { IBOutlet UIScrollView *scrollView; UIImageView *imageView; } @end
scrollViewController.m

- (void)viewDidLoad { [super viewDidLoad]; [scrollView setMinimumZoomScale:1.0]; [scrollView setMaximumZoomScale:5.0]; scrollView.delegate = self; scrollView.bounces = NO; [scrollView setShowsHorizontalScrollIndicator:NO]; [scrollView setShowsVerticalScrollIndicator:NO]; [scrollView setBackgroundColor:[UIColor blackColor]]; imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"test.jpg"]]; [imageView setContentMode:UIViewContentModeScaleAspectFit]; //如果不加这句的话 [imageView setFrame:CGRectMake(0, 0, scrollView.frame.size.width, scrollView.frame.size.height)]; //那么正常拖动是可以的，但是如果zoom了 就会有问题 //zoom发生后会把frame变成当前显示大小[imageview默认大小 屏幕显示大小 如是全屏则就是全屏大小] zoom变化导致frame同步改变了image的size 大小为frame大小 //image 的size改变后导致self.scrollView.contentSize 变成了frame的大小 从而contentSize变小了 无法实现正常拖动。 //然后根据zoom缩放比例变化。而不是根据实际图片大小。这么导致zoom后就无法拖动了[因为frame大小] scrollView.contentSize = imageView.frame.size; [scrollView addSubview:imageView]; [scrollView setZoomScale:scrollView.minimumZoomScale]; } #pragma mark - UIScrollViewDelegate - (UIView *)viewForZoomingInScrollView:(UIScrollView *)_scrollView { return imageView; }
