iOS7 相关资料整理

一、更改self.title中字体颜色及大小

解释：self.title为显示navigationController中间的标题文字.iOS5默认为白色，iOS7以后，默认为黑色。且没有直接修改的api

思路：获得当前navigationItem.titleView,强制转换为UILabel，然后做相应的颜色。

三、iOS7 UIStatusBar 字体颜色设置

iOS7后，字体颜色默认只有白黑两种，可以自定义window的方式，不过比较麻烦，先不介绍。

此处以设置为白颜色为例。

a、直接在xxx-info.plist来设置

info.plist中添加View controller-based status bar appearance，设置为NO

info.plist中添加Status bar style，设置为Transparent black style (alpha of 0.5)

b、xxx-info.plist结合代码

info.plist中添加View controller-based status bar appearance，设置为NO

在.m文件中加[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

或者在.m文件中加以下代码

//- (BOOL)prefersStatusBarHidden {

// return NO;

//}

//

//- (UIStatusBarStyle)preferredStatusBarStyle {

// return UIStatusBarStyleLightContent;

//}

四、iOS7 tintColor for
navigationBar

// for iOS7.0+

float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];

if (systemVersion >= 7.0)

{

[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

}

五、iOS6.0后，类似xxxFunction
is deprecated编译警告warning处理。

最近在把一个iOS5.0的老项目升级到iOS7.1,发现在iOS6.0的时候，就有一些函数和枚举值被废弃。

那么在做版本兼容的时候，我们可以使用respondsToSelector这个函数，具体怎么使用就不多说了。

iOS6.0以下版本的函数、枚举（红色表示iOS6.0以上可用）

- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated NS_DEPRECATED_IOS(2_0, 6_0);

- (void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion NS_AVAILABLE_IOS(5_0);

- (void)dismissModalViewControllerAnimated:(BOOL)animated NS_DEPRECATED_IOS(2_0, 6_0);

- (void)dismissViewControllerAnimated: (BOOL)flag completion: (void (^)(void))completion NS_AVAILABLE_IOS(5_0);

typedef NS_ENUM(NSInteger, UILineBreakMode) {

UILineBreakModeWordWrap = 0, // Wrap at word boundaries

UILineBreakModeCharacterWrap, // Wrap at character boundaries

UILineBreakModeClip, // Simply clip when it hits the end of the rect

UILineBreakModeHeadTruncation, // Truncate at head of line: "…wxyz". Will truncate multiline text on first line

UILineBreakModeTailTruncation, // Truncate at tail of line: "abcd…". Will truncate multiline text on last line

UILineBreakModeMiddleTruncation, // Truncate middle of line: "ab…yz". Will truncate multiline text in the middle

} NS_DEPRECATED_IOS(2_0,6_0);

typedef NS_ENUM(NSInteger, NSLineBreakMode) { /* What to do with long lines */

NSLineBreakByWordWrapping = 0, /* Wrap at word boundaries, default */

NSLineBreakByCharWrapping, /* Wrap at character boundaries */

NSLineBreakByClipping, /* Simply clip */

NSLineBreakByTruncatingHead, /* Truncate at head of line: "…wxyz" */

NSLineBreakByTruncatingTail, /* Truncate at tail of line: "abcd…" */

NSLineBreakByTruncatingMiddle /* Truncate middle of line: "ab…yz" */

} NS_ENUM_AVAILABLE_IOS(6_0);

// Deprecated: use NSTextAlignment enum in UIKit/NSText.h

typedef NS_ENUM(NSInteger, UITextAlignment) {

UITextAlignmentLeft = 0,

UITextAlignmentCenter,

UITextAlignmentRight, // could add justified in future

} NS_DEPRECATED_IOS(2_0,6_0);

/* Values for NSTextAlignment */

typedef NS_ENUM(NSInteger, NSTextAlignment) {

NSTextAlignmentLeft = 0, // Visually left aligned

#if TARGET_OS_IPHONE

NSTextAlignmentCenter = 1, // Visually centered

NSTextAlignmentRight = 2, // Visually right aligned

#else /* !TARGET_OS_IPHONE */

NSTextAlignmentRight = 1, // Visually right aligned

NSTextAlignmentCenter = 2, // Visually centered

#endif

NSTextAlignmentJustified = 3, // Fully-justified. The last line in a paragraph is natural-aligned.

NSTextAlignmentNatural = 4, // Indicates the default alignment for script

} NS_ENUM_AVAILABLE_IOS(6_0);
