BasicGraphics

iOS基本圖形繪製, 包括: 線, 弧線, 三角形, 橢圓, 矩形, 圓角矩形, 貝塞爾曲線等. 效果如下圖:

+ bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:
+ bezierPathWithArcCenter:radius:startAngle:endAngle:clockwise:
 

+ bezierPathWithCGPath:

這是另一種更加底層的繪製方法.

深色背景下設定標題欄為白色

背景色為黑色, 需設定狀態列(顯示訊號, 時間, 電量等)為亮色, 有兩種方法:

• Info.plist新增View controller-based status bar appearance, 設定value為NO. 新增

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent
 
];  

• ViewController.m中實現 - (UIStatusBarStyle) preferredStatusBarStyle 方法

- (UIStatusBarStyle) preferredStatusBarStyle
{
    return UIStatusBarStyleLightContent;
}

並且在ViewController.m中呼叫此方法.

[self preferredStatusBarStyle];

(注意刪掉Info.plist中的View controller-based status bar appearance項)
