If you store the data for the conversations in an NSData object, the folks at the CocoaDev wiki have posted an NSData category that adds gzip and zlib compression / decompression as simple methods.

Have you tried this delegate Objective-C: – (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar Swift: func searchBarSearchButtonClicked(searchBar: UISearchBar) See the documentation for any searchbar delegates. https://developer.apple.com/documentation/uikit/uisearchbardelegate

The perfect and short way to convert nsstring to hexadecimal values NSMutableString *tempHex=[[NSMutableString alloc] init]; [tempHex appendString:@”0xD2D2D2″]; unsigned colorInt = 0; [[NSScanner scannerWithString:tempHex] scanHexInt:&colorInt]; lblAttString.backgroundColor=UIColorFromRGB(colorInt); The macro used for this code is—- #define UIColorFromRGB(rgbValue) [UIColor \colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \ green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \ blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
Use the selectedIndex property on the UITabBarController. More information can be found in the UITabBarController Class Reference. controller.selectedIndex = 4; or use [controller setSelectedIndex:4];
