我只想添加明显的按钮“在Safari中打开”
@H_301_2@我怎么能以简单的方式做到这一点.
#pragma mark - Share the link - (IBAction)activityButtonPressed:(id)sender { NSString *textToShare = @"I just shared this from my App"; // UIImage *imageToShare = [UIImage imageNamed:@"Image.png"]; NSURL *urlToShare = [NSURL URLWithString:@"http://www.google.com"]; NSArray *activityItems = [NSArray arrayWithObjects:textToShare,urlToShare,nil]; UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:Nil]; //This is an array of excluded activities to appear on the UIActivityViewController //activityVC.excludedActivityTypes = @[UIActivityTypeMessage,UIActivityTypeCopyToPasteboard,UIActivityTypeSaveToCameraRoll]; [self presentViewController:activityVC animated:TRUE completion:nil]; }
解决方法
因为nevo shalev说你需要子类
UIActivity class
这是一个例子:
UrlActivity.h
#import <UIKit/UIKit.h> @interface UrlActivity : UIActivity @end
UrlActivity.m:
#import "UrlActivity.h" @implementation UrlActivity - (NSString *)activityType { return @"your Custom Type"; } - (NSString *)activityTitle { return @"Title to display under your icon"; } - (UIImage *)activityImage { return [UIImage imageNamed:@"your icon.png"]; } - (BOOL)canPerformWithActivityItems:(NSArray *)activityItems { // basically in your case: return YES if activity items are urls } - (void)prepareWithActivityItems:(NSArray *)activityItems { //open safari with urls (activityItems) } +(UIActivityCategory)activityCategory { return UIActivityCategoryShare; // says that your icon will belong in application group,not in the lower part; } @end
并在您的主文件(导入UrlActivity.h后):
#pragma mark - Share the link - (IBAction)activityButtonPressed:(id)sender { NSString *textToShare = @"I just shared this from my App"; // UIImage *imageToShare = [UIImage imageNamed:@"Image.png"]; NSURL *urlToShare = [NSURL URLWithString:@"http://www.google.com"]; NSArray *activityItems = [NSArray arrayWithObjects:textToShare,nil]; // create an array with your custom activity and add it to the activityVC NSArray *appActivities = [NSArray arrayWithObjects:[[UrlActivity alloc] init]]]; UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:appActivities]; //This is an array of excluded activities to appear on the UIActivityViewController //activityVC.excludedActivityTypes = @[UIActivityTypeMessage,UIActivityTypeSaveToCameraRoll]; [self presentViewController:activityVC animated:TRUE completion:nil]; }
