Adding left padding to the UITextField, when add background Image

 Adding left padding to the UITextField, when add background Image

#import "QuartzCore/QuartzCore.h"  

  // First import this Framework

......

UITextField *commentTextField = [[UITextField alloc]initWithFrame:CGRectMake(40, 8, 250, 34)];

    commentTextField.delegate = self;

    commentTextField.placeholder = @"Comment";

    [commentTextField setFont:[UIFont boldSystemFontOfSize:12]];

    commentTextField.textAlignment = UITextAlignmentLeft;

    commentTextField.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 12, 20)];

    commentTextField.leftViewMode = UITextFieldViewModeAlways;

    commentTextField.background = [[UIImage imageNamed:@"textBox.png"] stretchableImageWithLeftCapWidth:7topCapHeight:17];

    [self.view addSubview: commentTextField];

IOS 7 AVPlayer - AVPlayerItem duration incorrect in iOS 7

AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:movieURL];
CMTime duration = playerItem.duration; float seconds = CMTimeGetSeconds(duration);
NSLog(@"duration: %.2f", seconds);
This worked fine with iOS 6 but with iOS 7 for some reason it returns NaN. When inspecting  playerItem.duration the CMTime object has 0's with a flag of 17.
But player works fine, just the duration is wrong.
So over come this problem Please import these frameworks.
#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>
#import <MediaPlayer/MediaPlayer.h>
#import <CoreMedia/CoreMedia.h>
#import <AVFoundation/AVAsset.h>

In place of above code you can paste this code:AVURLAsset *asset = [AVURLAsset assetWithURL: movieURL];Float64 duration = CMTimeGetSeconds(asset.duration);NSLog(@"duration..%f", duration);

Disable ARC for a Single file in a project in iOS

Disable ARC for individual files by adding the -fno-objc-arc compiler flag for those files.

You add compiler flags in Targets -> Build Phases -> Compile Sources. You have to double click on the right column of the row under Compiler Flags.
