小编Gen*_*ios的帖子

朋友我有简单的音频播放器(MPMoviePlayerController),可以播放音频流.在iOS 11上我有非常麻烦的麻烦,一千次我有错误,我的流被停止:

NSURLConnection finished with error - code -1002

我粘贴这段代码(我在stackowerflow上看到这段代码),但这对我没有帮助:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>cast.mysite.com</key>
            <dict>
                <key>NSExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSIncludesSubdomains</key>
                <true/>
            </dict>
        </dict>
    </dict>

也许你知道最好的解决方案

我有一些项目,我必须从JSON粘贴图像.我试图找到关于这个的任何教程,试着看看这个主题的任何视频,但没有.所以我的问题有:

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSDictionary *allDataDictionary = [NSJSONSerialization JSONObjectWithData:webdata options:0 error:nil];
    NSDictionary *playlist =[allDataDictionary objectForKey:@"playlist_data"];

    for (NSDictionary *diction in playlist) {

        NSString *name = [diction objectForKey:@"text1"];
        NSString *namesong = [diction objectForKey:@"text2"];
        NSString *images = [diction objectForKey:@"image"];
        NSLog(@"%@", images);        
        [array addObject:text1];
        [array2 addObject:text2];
    }
    [[self tableTrack]reloadData];
}

我添加了文本1到单元格也文本2它的工作完美,但如何将图像添加到数组3(我的tableView中的单元格中的图像)？我也尝试添加图像,但它对我不起作用:

NSURL *imageURL = [NSURL URLWithString:[appsdict objectForKey:@"image"]];
NSData *imageData = [NSData dataWithContentsOfURL:imageURL];
UIImage *imageLoad = [[UIImage alloc] initWithData:imageData];
cell.imageView.image = imageLoad;

请帮助解决我的问题,或者给JSON提供一些解析图片的教程,youtube也没有JSON解析的完美教程.谢谢!

我有一些有趣的问题我的Xcode 6.1.1蓝色图标就像在xcodeproj文件上消失了,我已经安装了新版本千次,但它不是解决方案.此外,我试图找到一些关于它的主题,但真的没有!

我需要获取当前用户位置（纬度、经度），但我找不到解决方案，因为所有解决方案仅适用于 iOS 6,7,8。例如，我有这段代码，但在 iOS 11.3.1 上它仍然无法工作。

#import <CoreLocation/CoreLocation.h>

@interface ViewController () <CLLocationManagerDelegate>

@property (weak, nonatomic) IBOutlet UILabel *latitudeValue;
@property (weak, nonatomic) IBOutlet UILabel *longtitudeValue;

@property (nonatomic,strong) CLLocationManager *locationManager;

- (void)viewDidLoad
{
    [super viewDidLoad];

    if ([CLLocationManager locationServicesEnabled]) {
        self.locationManager = [[CLLocationManager alloc] init];
        self.locationManager.delegate = self;
        [self.locationManager startUpdatingLocation];
    } else {
        NSLog(@"Location services are not enabled");
    }
}

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations lastObject];
    self.latitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.latitude];
    self.longtitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.longitude];
}

我有问题.我有动态tableview.所以我需要在textLabel中更改文本大小.我试过了:

一:

cell.textLabel.font = [UIFont systemFontOfSize:30.0f];

二:

cell.textLabel.font = [UIFont boldSystemFontOfSize:12.0];

三:

UIFont *myFont = [ UIFont fontWithName: @"Arial" size: 30.0 ];
cell.textLabel.font  = myFont;

但我的文字标签没有改变.所以detailtextlabel - 完全改变但文本标签 - 没有.我做错了什么？谢谢

我有UIImageView就像简单的Gallery,可以从JSON获取数据.

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSDictionary *allDataDictionary = [NSJSONSerialization JSONObjectWithData:webdata options:0 error:nil];
    NSArray *tmp =[allDataDictionary objectForKey:@"gallery"];
    if (tmp.count>0){

        for (NSDictionary *diction in tmp) {
            [self.patternImagesArray addObject:diction];
        }

        NSLog(@"%@", self.patternImagesArray);
      //  [loading stopAnimating];

    }

    [self.collectionView reloadData];
}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    PatternView *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"PatternCell" forIndexPath:indexPath];

    NSString *myPatternString = [[self.patternImagesArray objectAtIndex:indexPath.row] valueForKey:@"thumb"];

    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:myPatternString]];
    cell.patternImageView.image = [UIImage imageWithData:data];

    return cell;


}

为了给出完整的图像我使用这个:

-(void)viewDidLoad{

    NSString *path=[_newsData valueForKey:@"bigimg"];

    NSData* imageData = [NSData dataWithContentsOfURL: [NSURL URLWithString: path]];

    UIImage* image …
