iOS學習，ios學習路線

iOS學習，ios學習路線

思路：

　　1.new 一個 Empty 尾碼為 .txt 檔案，內容隨筆拷貝一段

　　2.用 NSString 接收本地檔案，再用一個標題拼接字串

　　3.建立一個 NSMutableParagraphStyle 執行個體，設定標題置中、標題距離本文間隔

　　4.建立一個 NSMutableParagraphStyle 執行個體，設定本文靠左對齊、每段開頭縮排 10

　　5.建立一個基礎動畫的執行個體，用代理監聽動畫結束

話不多說上代碼

#pragma mark -- 拼接字元- (void)loadData:(NSString *)filename {        //第一個段落    NSMutableParagraphStyle *first = [[NSMutableParagraphStyle alloc]init];    first.alignment = NSTextAlignmentCenter;    first.lineSpacing = 10;        //第二個段落    NSMutableParagraphStyle *second = [[NSMutableParagraphStyle alloc]init];    //從左開始寫    second.alignment = NSTextAlignmentLeft;    //首行縮排    second.firstLineHeadIndent = 10;    //間距    second.lineSpacing = 10;        UIFont *titleFont = [UIFont systemFontOfSize:16];    UIFont *contextFont = [UIFont systemFontOfSize:13];        NSMutableAttributedString *str1 = [[NSMutableAttributedString alloc]initWithString:@"遊戲許可及服務合約" attributes:@{NSParagraphStyleAttributeName:first,NSFontAttributeName:titleFont}];        //標題拼接本文，本文前加分行符號    NSString *str = [NSString stringWithFormat:@"\n%@",filename];        NSMutableAttributedString *str2 = [[NSMutableAttributedString alloc]initWithString:str attributes:@{NSParagraphStyleAttributeName:second,NSFontAttributeName:contextFont}];        [str1 appendAttributedString:str2];    _textView.attributedText = str1;}#pragma mark -- 關閉動畫- (void)closeAniamtion:(UIView *)view {    CABasicAnimation *animation = [CABasicAnimation animation];    animation.keyPath = @"transform.scale";    animation.toValue = @0.9;    animation.duration = 0.4;    animation.delegate = self;    animation.removedOnCompletion = NO;    animation.fillMode = kCAFillModeForwards;    [view.layer addAnimation:animation forKey:@"closeAnimation"];}#pragma mark -- 本地 txt 檔案內容- (NSString *)filename {    //本地 txt 檔案    NSString *path = [[NSBundle mainBundle]pathForResource:@"淺遇時光，靜好無恙.txt" ofType:nil];    //取出內容    NSString *filename = [[NSString alloc]initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];    return filename;}

#pragma mark -- 代理監聽動畫停止- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag {    if ([_bgView.layer animationForKey:@"closeAnimation"] == anim) {        [_bgView removeFromSuperview];    }}
