图像未正确加载到uiimageView中

Question

Please check attached imageImage not loaded properly in UIImageView .

 profileCell.currentMsgView.userPicImageView sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",object.mediaPath]] placeholderImage:[UIImage imageNamed:@"defaultImage"] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { }]; 

Answer 1

Try by setting content mode like,

    profileCell.currentMsgView.userPicImageView.contentMode = UIViewContentModeScaleAspectFit;

And make sure that you have set proper constraints. If you have imageview of cell's size then your constraints should be like : top,leading,trailing,bottom

This may solve the problem.

Answer 2

Try this simple demo app for just learning :-

ViewController.h code is here :-

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIImageView *imageOutput;
- (IBAction)btnOutput:(id)sender;

@end

ViewController.m code is here :-

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)btnOutput:(id)sender {
    NSString *picUrl = @"http://cdn.wonderfulengineering.com/wp-content/uploads/2016/01/nature-wallpapers-9.jpg";
    NSURL *theUrl = [NSURL URLWithString:picUrl];
    NSData *imageData = [[NSData alloc]initWithContentsOfURL:theUrl];
    _imageOutput.image = [UIImage imageWithData:imageData];
}
@end

Replace whole code of info.plist with the following because without that you will not be able access "http site" because apple will block http site for security reason(for that right click on info.plist and open as source) :-
