小编use*_*231的帖子

我遇到了一个问题,即确定如何检测UIView被触及和UIView被点击.当它被触及时,我希望UIView改变它的背景颜色.当它被触摸时,我希望UIView执行某些任务.我想知道我是如何解决这个问题的.

-(void)viewDidLoad
{        
    UITapGestureRecognizer *dismissGestureRecognition = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDismissDoubleTap:)];
    dismissGestureRecognition.numberOfTapsRequired = 1;
    [sectionDismissDoubleView addGestureRecognizer:dismissGestureRecognition];

    UITapGestureRecognizer *dismissGestureDownRecognition = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissGestureDownRecognition:)];
    dismissGestureRecognition.numberOfTouchesRequired = 1;
    [sectionDismissDoubleView addGestureRecognizer:dismissGestureDownRecognition];
}

- (void)handleDismissDoubleTap:(UIGestureRecognizer*)tap {
    SettingsDismissDoubleViewController *settingsDouble = [[SettingsDismissDoubleViewController alloc] initWithNibName:@"SettingsDismissDoubleViewController" bundle:nil];
    [self.navigationController pushViewController:settingsDouble animated:YES];
}

- (void)dismissGestureDownRecognition:(UIGestureRecognizer*)tap {
    NSLog(@"Down");
}

我有一个问题,如下图所示,原始图像底部的图像向左倾斜90度.有没有办法计算角度的变化.我已经尝试了霍夫的变换,我可以检测到位置,但是我无法检测到变化的天使.是否有替代方法可以检测度数.

我目前正在尝试使用YII Framework扩展.但是,我遇到了一些问题.

我已经按照本网站中的一步一步程序进行了操作:https://github.com/drumaddict/skydrive-api-yii

但是,当我打电话的时候

Yii::import('protected.extensions.skydrive.SkyDriveAPI');

在PHP中.

它给了我 Uncaught exception 'CException' with message 'Alias "protected.extensions.skydrive.SkyDriveAPI" is invalid.

我是Yii框架的新手,需要一些帮助.愿任何人给我一些指示.

谢谢,Chan Yeoh

我遇到了将数据放入表视图的问题.这是我目前的代码.我无法从我尝试使用NSFetchedResultsController的类加载结果,但它不起作用.任何人都可以看到错误.这是头文件.

#import <UIKit/UIKit.h>
#import <CoreData/CoreData.h>
#import <sqlite3.h>
#import "FlickrFetcher.h"
@interface PersonList : UITableViewController {
    FlickrFetcher *fetcher;
    NSArray *nameList;
    NSArray *names;
    NSFetchedResultsController *results;
    NSArray *photos;
}
@property (retain, nonatomic)NSArray *nameList;
@property (retain, nonatomic)NSArray *names;
@property (retain, nonatomic)NSArray *photos;
@property (retain, nonatomic)NSFetchedResultsController *results;
@end

这是.m文件.

#import "PersonList.h"


@implementation PersonList
@synthesize nameList,names,results,photos;

 // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.

    if (self = …
