【iOS】アプリ系小ネタ4つ+UIColor系小ネタ

iOS

続いてアプリ系小ネタいきます！

指定した名前のStoryboardインスタンス取得

UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"HogeStoryboard" bundle:nil];



AppDelegate取得

HogeAppDelegate *appDelegate = (HogeAppDelegate *)[UIApplication sharedApplication].delegate;



UUID生成

CFUUIDRef uuidObj = CFUUIDCreate(nil);
NSString *uuid = (NSString*)CFBridgingRelease(CFUUIDCreateString(nil, uuidObj));
CFRelease(uuidObj);



アプリショートバージョン取得

Info.plistのBundle versions string, shortを取得しますー

NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];



【UIColor】#ffffff形式の文字列からUIColor取得

はい、alphaはスルーしてますw

+ (UIColor *)colorWithHexString:(NSString*)string {
	string = [string stringByReplacingOccurrencesOfString:@"#" withString:@""];
	uint32_t hex = 0x0;
	NSScanner *scanner = [NSScanner scannerWithString:string];
	[scanner scanHexInt:&hex];

	CGFloat red = ((hex & 0xff0000) >> 16) / 255.0f;
	CGFloat green = ((hex & 0x00ff00) >> 8) / 255.0f;
	CGFloat blue = ((hex & 0x0000ff) >> 0) / 255.0f;

	return [UIColor colorWithRed:red green:green blue:blue alpha:1];
}
