系统字体及动画

1.设置圆角的UITextView

首先，添加头文件：#import <QuartzCore/QuartzCore.h>

第二，设置textview的layer

textview.layer.cornerRadius = 5;

textview.layer.masksToBounds = YES;

第三，ok了。哈哈

2.获取全部的系统字体

NSArray *familyNames = [UIFont familyNames]; NSMutableDictionary *dics = [[NSMutableDictionary alloc] init]; NSMutableArray *ar = [[NSMutableArray alloc] init]; for( NSString *familyName in familyNames ) { printf( "Family: %s \n", [familyName UTF8String] ); NSArray *fontNames = [UIFont fontNamesForFamilyName:familyName]; for( NSString *fontName in fontNames ) { printf( "\tFont: %s \n", [fontName UTF8String] ); [dics setObject: fontNames forKey: familyName]; } NSLog( @"dics is %@" , dics ); [ar addObject: dics]; }

NSMutableArray *array = [[[NSMutableArray alloc] init] autorelease]; NSArray* familys = [UIFont familyNames]; for (NSString *obj in familys) { NSArray* fonts = [UIFont fontNamesForFamilyName:obj]; for (id font in fonts) { [array addObject:font]; } }

3.设置动画

[UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations];
