自定义title 后导致的坐标无法居中 问题解决方案

//Overide the drawing of the background UINavigationBar

@implementation UINavigationBar (CustomImage)

- (Class)class

{

returnNSClassFromString(@"HFNavigationBar");

}

- (void)drawRect:(CGRect)rect

{

UIImage *image = [UIImageimageNamed:@"[e-mail]"];

[image drawInRect:CGRectMake(self.bounds.origin.x,self.bounds.origin.y,self.bounds.size.width,self.bounds.size.height+5) ];

self.tintColor = [UIColorclearColor];

}

//让title居中 否则会根据lefttile 和righttitle的存在与否进行变化

-(void)layoutSubviews {

[superlayoutSubviews];

for (id viewinself.subviews) {

if ([viewisKindOfClass:NSClassFromString(@"UILabel")]) {

// Do whatever you want with view here

[viewsetFrame:CGRectMake(0 ,0,320,44) ];

}

}

}

@end

titleLabel.font = [UIFontboldSystemFontOfSize:22.0];

titleLabel.shadowColor = [UIColorcolorWithWhite:0.0alpha:0.5];

titleLabel.textAlignment =UITextAlignmentCenter;

titleLabel.textColor = [UIColorwhiteColor];// change this color
